Medicinal plants from wild sources cannot ensure consistent quality due to genetic variability found in the natural population, geographical variations and season of collection. Therefore, there is a need to cultivate medicinal plants containing active principles, and to enhance their yields using organic farming practices and post harvest technologies. The present investigation was taken up to enhance the root biomass using NPK as well as forskolin levels under different fertilizer amendments. Both root biomass as well as forskolin contents were higher by 3-folds when 50% NPK plus 10 tonnes of farm yard manure were supplied to the plants followed 50% NPK plus 5 tonnes of vermicompost per hectare.

Indian J pharm Sci 2012, 74(3), 261-5.

Aim of present study was to investigate the antimicrobial activity of Cenchrus ciliaris and Cenchrus setigerus extracts in order to use it as a possible source for new antimicrobial substances against important human pathogens. Crude extracts of the stem of Cenchrus ciliaris and Cenchrus setigerus were evaluated against some medically important pathogens viz. Escherichia coli, Raoultella planticola, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Enterobacter aerogenes, Candida albicans and Aspergillus flavus. The dried and powdered stems were successively extracted with hexane, toluene, isopropyl alcohol, acetone and ethanol using soxhlet assembly. The antimicrobial activity assay was done by both disc diffusion and serial dilution methods. Isopropyl alcohol extract of Cenchrus setigerus showed highest activity against Escherichia coli. The test pathogens were more sensitive to the isopropyl alcohol, acetone and ethanol extracts than to the hexane and toluene extracts except against Bacillus subtilis. Result reveals that the most bioactive compound was cycloleucolenol-9,19-cycloergost-24 (28)-en-3-ol, 4, 14-dimethyl acetate in both the species of Cenchrus grass, (19.15%) in isopropanol extract of Cenchrus setigerus whereas, (14.03%) in acetone extract of Cenchrus ciliaris.

Algal biodiversity, population and percentage composition of different algal groups from river Godavari was studied for two consecutive years (Aug, 2003-July, 2005). Algal collection was carried out from five selected sampling stations of river from Nashik to Nandur-Madhmeshwar dam. Monthly collection of algal forms were carried out and analyzed for its qualitative and quantitative study. At many sampling stations domestic wastes and municipal sewage is being dumped daily in addition to agricultural run-off, which causes the enrichment of nutrients in river water causing the luxurious growth of algae. During present investigations, six algal groups were recorded, viz, Chlorophyceae, Charophyceae, Cyanophyceae, Euglenophyceae, Dinophyceae and Bacillariophyceae. During present studies tremendous variations in algal diversity, its population and percentage composition was noticed. Change in water flow, transparency and temperature affected the growth and abundance of algae in river water. Chlorophyceae was found to be the dominant group followed by Bacillariophyceae, Cyanophyceae and Euglenophyceae. Charophyceae and Dinophyceae members were sparsely recorded.

Wide range of morphological mutations affecting almost all the parts of the plant and seed characteristics were isolated in M₂ generation of a popularly grown cultivar of urdbean, TAU-1, treated with three well known mutagens, ethyl methane sulphonate (EMS), methyl methane sulphonate and gamma rays (GR). Seeds of this cultivar were treated with three doses of EMS (0.02, 0.03 and 0.04 M), MMS (0.0025, 0.05 and 0.01 M) and gamma rays (30, 40 and 50 KR). The mutagen administered seeds were sown in experimental fields to raise M₁ progeny. Seeds of M₁ plants and control were harvested separately and sown to raise M₂ population. The M₂ propeny were screened for viable mutations. In all seventeen different types of viable morphological mutations were observed. These included seven types of plant type mutations (sterile, tall,dwarf, viney, spreading, early, high yielding) and three types of leaf mutations (narrow elogated, thick leathery and curly leaf mutations), six types of pod (long pod, short pod, hariy pod, narrow elongated pod, fiat pod and large pod) and one type of seed (bold seed) mutations. Results indicated that all mutagenic treatments were effective in inducing mutations in urdbean, during M₂ generation. The spectrum and frequency of mutations varied with the type of mutagen. Some mutation types occurred more frequently than others. The frequency and spectrum of viable mutations were relatively high with gamma radiation followed by EMS and MMS.

Polyhydroxybutyrate is a polyhydroxyalkonate, a polymer belonging to the polyester class. It is regarded as a source of potentially useful biodegradable natural plastic such as polypropylene. PHB accumulate as reserve energy material in the cytoplasm of certain bacteria during unbalanced growth conditions. As the production cost of PHB is quite high compared to non - degradable plastics, the present work has been focused on the isolation of potential bacterial strains with high PHB accumulating ability. PHB producing Bacillus strain was isolated through standard protocols and identified using Nile Blue A staining technique. The dye induces florescence on binding to the polymer. Further, PHB was extracted using sodium hypochlorite and its chemical nature of the material was confirmed using UV, IR and NMR analysis.

It is well known that plant growth is affected in soils. Arbuscular mycorrhizal fungi play a significant beneficial role in 95% of the vascular plants on the earth. We hypothesize that mycorrhizal fungi reduces salt stress in plants. To prove our hypothesis, an experiment was conducted to determine the benefit of mycorrhizal fungi by comparing mycorrhizal fungal inoculated Bt-Cotton to non-inoculated Bt-Cotton under salts like NaCl, Na₂SO₄ and combination of NaCl & Na₂SO₄ in different concentrations in soil. Salinity did affect the plant growth with increasing stress rate at higher salt concentrations particularly in non-inoculated plants. Inoculated plants were healthier at low to medium salt concentrations; however, higher salt concentration affected the growth. Mycorrhiza inoculated plants in low to medium salt concentrations had higher root mass and colonization compared to high salt concentration. Further research is needed to study the physiological response of mycorrhizal plants to salt stress.

Study was conducted to determine the effects of arbuscular mycorrhizal (AM) fungi inoculation on growth of cotton grown under well watered and water stressed pot culture conditions. 15 days old cotton seedlings were planted in earthen pots after treatment with or without the AM fungi. Roots were sampled after 45, 90, and 135 days of growth stages to quantify AM fungi. Mycorrhizal colonization was higher in water-stressed plants than well-watered plants. Biomass was higher in mycorrhizal than non-mycorrhizal plants irrespective of water treatments. However the plants irrigated with alternate watering schedule had shown higher biomass and than those treated with daily watering. The improved growth in cotton plants reported here demonstrate the potential of mycorrhizal inoculation to reduce the effects of drought stress and useful for the better performance under stress conditions.

This work was carried out for studying the aero-algal flora from Pune. For this, various terrestrial and sub-aerial samples were collected. Terrestrial samples were collected from dry soil and sub-aerial samples were collected from brick wall, tree trunk, cemented wall, roof etc. during the month of July-August 2009. All the samples were cultured using B.G - 11 medium and were allowed to grow under natural condition. Slides were prepared and scanned for identification of various algal forms. It has been observed that one of the soil sample collected outside physics department, Fergusson College, Pune shows the presence of Oedodadium in it. Oedocladium, recognized as distinst genera is being reported for the first time from Pune. Only fourteen species have been known worldwide, out of which only five species are reported from India. The present form has been further identified as Oedocladium prescottii. It is associated with genera such as Lyngbya, Chroococcus, Phormidium, Chlorella, Spirulina, Aphanocapsa, Gloeotheca and Microcoleus, the dominant being, Chroococcus. Due to the dominance of the associated blue-green algae, this can be one of the major reasons, for suppressing the growth of Oedocladium and thus affecting its existence.

Dacryodes edulis - African Pear is of socio-economic importance in the Southern region of Nigeria where it is a major auxiliary revenue source for farmers. Cluster and Principal Component analyses of the fruit data showed three distinct groupings; small-sized fruit, large-sized fruit and an intermediary group of mixed fruit types. These reflect the cadre of genetic diversity inherent in the taxon, and constitute a possible veritable tool for its improvement. Notwithstanding the diversity, the prevailing spread pattern of the taxon across the region threatens to erode a section of the species genetic richness; the small-sized fruit types - var. parvicarpa, as well as undermine the genetic integrity of large-sized fruit var. edulis population. The trend is driven by a vendor/farmer preference for the large-sized fruit type across the region, and except there is deliberate In situ and Ex-situ conservation efforts, these intraspecific diversities of the species may be lost altogether.

Survey on the symptoms and severity of the leaf spot disease of Pongamia pinnata L. was conducted in the different nurseries in areas around Bangalore. Survey revealed that leaf spot was major disease found in many nurseries causing severe problems in seedlings. Severely infected leaves defoliated prematurely. The associated organism of leaf spot disease of P. pinnata was found to be Colletotrichum gloeosporioides Penz., isolated from the diseased leaves and the pathogenicity was established with the isolated fungus. Efficacy of methanol extract of leaf and bark (0.25, 0.5, 1, & 2%) of Prosopis juliflora (Sw.) DC. was evaluated against C. gloeosporioides both in vitro and in vivo condition along with one standard fungicide (Indofil-M 45 - Mancozeb 75% WP). Extract of bark and leaf showed considerable inhibition (up to 90% and above) against tested pathogen in both 1 & 2% concentrations. But, the fungitoxicity varied with bark and leaf extracts. As 1 & 2% of extract did not show much difference in in vitro study, field trial was carried out using 3 concentrations (0.25, 0.5 &1%) of leaf and bark extract of P.juliflora by two sequential foliar sprays at an interval of 15 days to the seedlings which are infected with leaf spots. Reduction in disease severity was not significant in the first month after treatment. But in second month onwards, significant decrease in percentage of infection and disease severity index (DSI) was observed and the 0.5 &1% treatment was on par with chemical fungicide (Indofil-M45).

Aloe vera is a wonder plant with numerous health benefits. It acts as a natural fighter against all sorts of infection, an efficient anti-oxidant, helps in treating all digestion related problems, heartburn, arthritis, stress, diabetes, rheumatic pain, asthma, cancer and AIDS. It also acts as a laxative, beauty enhancer and has an effect on lowering blood sugar levels in diabetics. When taken internally works on congestion, intestinal worms, indigestion, stomach ulcers, colitis, hemorrhoids, liver problems such as cirrhosis and hepatitis, kidney infections, urinary tract infections, prostate problems and acts as a general detoxifier. Aloe has been proved to be a plant of amazing medicinal properties by researchers. The medicinal value of the plant is in its gel like pulp obtained by peeling its leaves which has been recognized since centuries. Its juice has cooling properties, is anabolic in action, a fighter of 'pitta', storehouse of phytochemicals and guards against fever, skin diseases, burns, ulcers, boils eruptions, etc. Commercially, Aloe can be found in pills, sprays, ointments, lotions, liquids, drinks, jellies, and creams, to name a few of the thousands of products available. In the present scenario, the Aloe industry is blooming but the consumers are misguided leading to unfavourable outcome. So, there is an urgent need to educate about the importance of Aloe vera for human race and popularize it for greater interest.

Clitoria ternatea L. is an important rare medicinal plant species with memory-enhancing ability used as crude drugs in many ayurvedic medicines. The objectives were as follows: A. To develop a protocol for rapid clonal propagation of the important medicinal climber, C. ternatea L., through in vitro tissue culture of embryo explants through callogenesis and organogenesis, and B. Antibacterial study of ethanolic extract of in vitro raised plant and callus mass against Pseudomonas aeruginosa (MTCC189), Bacillus subtilis (MTCC8), Escherichia coli (MTCC1), and Klebsiella pneumonia (MTCC3883), respectively. Explants were cultured on Murashige and Skoog's (MS) medium supplemented with different concentrations and combinations of 6-benzylamino purine (BAP), (2,4-dichlorophenoxy acetic acid (2,4-D), and α-naphthalene acetic acid (NAA) for shoot and root induction. The disc diffusion method was adopted for antimicrobial study of the plant extract. The sub-cultured of callus on MS basal medium supplemented with BAP (2.5 mg/l) and NAA (0.5 mg/l) showed highest rate of shoot multiplication. In vitro shoots were rooted on to the MS basal medium supplemented with NAA (0.5 mg/l). The sub-culture of callus on MS basal medium supplemented with BAP (1 mg/l) and NAA (0.5 mg/l) showed highest rate of root multiplication from callus. The antibacterial activity of the ethanolic extracts of in vitro grown products of C. ternatea L. was found to have antimicrobial activity against all tested microorganisms. Preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, saponins, carbohydrates, and steroids in the in vitro grown products of C. ternatea L. An efficient protocol was developed for successful micropropagation and multiple plant regeneration of an important medicinal plant C. ternatea L. It is a widely used in ayurvedic medicine because of its multi-potent bioactive molecules and significant antibacterial properties.

Bio-pesticides (also known as Biological Pesticides) are certain types of pesticides derived from such natural materials as animals, plants, bacteria and certain minerals, for example at the end of 1998 there were approximately 175 registered Bio-pesticide active ingredients and 700 products of bio-pesticides. The Chemical Pesticide consumption is increasing @ 20% per annum. The pest and disease cause over Rs.29,000 cores crop losses per annum. This situation has been caused by indiscriminate use of chemical pesticides resulting in development of resistance in pests and resurgence of minor pests. Rejection of Indian argil exports are more than Rs.4000 cores per annum, because of very high pesticide residue contents. WHO estimates 1 million pesticide-poisoning cases and 20,000 death every year globally. This is due to high pesticide residues in food chain. Chemical pesticides cause significant health hazards like Vomiting, Paralysis, Blindness, Coma, Death, damage to respiratory tract, allergies, anemia etc.

Deals with rapid and efficient micropropagation protocol of Oroxylum indicum Vent., an important medicinal plant. Owing to very short viability period of its seeds as well as need for extra care in the first four years after conventional propagation, and excessive use by local people, its population in natural habitats has declined in the recent years. The in vitro culture of its nodal segments in Gamborg's B5 medium was performed for multiple shoot propagation and rooting in presence of various cytokinins and auxins. A maximum of ten shoots per explant was produced when 5.0 mg/l BA was supplemented in the medium, with maximum shoot length (3.74 cm) and leaf number (33.6) in presence of 0.3 mg/l KN and 5.0 mg/l BA, respectively after 60 days of culture. The maximum in vitro roots (5.2 per microshoot) was produced in half strength B5 medium supplemented with 0.5 mg/l NAA. The hardened and acclimatized plantlets were successfully transferred into potting mixture of soil, perlite and compost (1:1:1) with 70% survival rate.

Plant growth promoting rhizobacteria promote plant growth and productivity has internationally been accepted. Fluorescent pseudomonas have been extensively studied as a plant growth promoting rhizobacteria (PGPR). Pseudomonads are known to interact with host plant via chemical mediators that develop a symbiotic relationship. During their close association, they influence the growth of host plant by delivering beneficial effects in rhizosphere. Pseudomonads promote the growth of plants either by direct supply of nutrients, synthesis of phytohormones, solubilization of minerals, or indirectly as a biocontrol agent suppressing the pathogens. Cumulative effect of combination of above properties projects it as bacteria of great economic importance. This is usually achieved by either one or blend of several factors released in rhizosphere bysymbiont. These include secretive secondary metabolites e.g. Antibiotics, toxins, enzymes, HCN etc. which inhibits the pathogen or chelators like siderophores which generate the microenvironment, a competitive one for pathogen. These bioformulations also enhanced soil fertility and the PGPR activity also increased grain yield.
