There is a growing demand for ecologically compatible environment friendly technique in agriculture that might be able to provide adequate supply of nutrients for the increasing human populations through improvement of the quality and quantity of agricultural products. Under the changing climatic scenario of global fluxes of the key biogenic greenhouse gases (CO 2 , methane and nitrous oxide), and some other environmental problems, the application of beneficial microorganisms in agriculture would serve as an important alternative gateway to some of the traditional agricultural techniques. Microorganisms of agricultural importance represent key ecological strategy for integrated management practices like nutrient management, disease and pest management in order to reduce the use of chemicals in agriculture as well to improve cultivar performance. The present review is intended to focus on the emergence of agriculturally important microorganisms (AIMs) to develop an ideal agricultural system through efficient utilization of nutrients and recycling of energy and thereby to preserve the natural ecosystem resources under climate change. The progress to date in using the beneficial microflora in a variety of applications related to agriculture along with key mechanism of action is also discussed in this review.","PeriodicalId":22829,"journal":{"name":"The Journal of Phytology","volume":"21 1","pages":"26-41"},"PeriodicalIF":0.0,"publicationDate":"2016-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85676148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Media supplemented with the growth regulator naphthalene acetic acid (NAA) (1.5 mg/l) + 6-benzyle adenine (0.25 mg/l) was used for the initial induction of the callus and further subcultured to the same media for the proliferation of the callus. Pale yellow and green calli were noticed, which depends on incorporation of the growth hormones and their varying concentrations. Murashige and Skoog medium in addition with 2 mg/l kinetin+ 0.5 mg/l indole-3-acetic acid (IBA) + 500 mg/l casein hydrolysate resulted in maximum regeneration. Media supplemented via IBA (0.5 mg/l) and NAA (0.5 mg/l) (98%) was found to be optimum for rhizogenesis for in vitro regenerated plants. For acclimatization 5-6 weeks mature in vitro regenerated plants were transferred into the greenhouse for acclimatization. The histological study revealed the presence actively dividing meristematic cells in callus. The occurrence of the peripheral meristematic zone associated with callus was noticed in after 20 days, which formed the shoot meristems after 45 days of incubation. To our knowledge, this is the first report on high-frequency plant regeneration which was carried out indirectly from the leaf explants which was grown in controlled environment with varying concentration of the growth regulators and histology of callus of different stages from leaf explants of C. intybus.","PeriodicalId":22829,"journal":{"name":"The Journal of Phytology","volume":"19 1","pages":"7-12"},"PeriodicalIF":0.0,"publicationDate":"2016-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87247196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most natural compounds exhibit their protective effects by eliciting antioxidant potential. Sulfated polysaccharide was isolated from the brown algae Padina tetrastromatica , then purified and evaluated for its composition and in vitro antioxidant and antimitotic activities. Both ethanolic sulfated polysaccharide (ESPS) and ethanolic sulfated polysaccharide-column purified (ESPS-CP) exhibited considerable amount of carbohydrates (11.2% and 17.6%), sulfate (11.4% and 7.4%), fucose (5.5% and 15.7%), uronic acid (4.7% and 11.8%), xylose (0.5% and 0.03%) and sulfated polysaccharide (2.4% and 12.7%) content. The FTIR analysis and phytochemical screening also confirmed the presence of sulfated polysaccharides. In the in vitro antioxidant activity determination using DPPH (1-1-diphenyl 2-picryl hydrazyl) radical scavenging activity, hydroxyl radical scavenging activity, superoxide anion scavenging activity, hydrogen peroxide scavenging activity, total antioxidant activity and reducing power, ESPS showed more activity than ESPS-CP. In the case of nitric oxide radical scavenging, ESPS-CP was found to be more effective. At a concentration of 2mg/ml, both samples were potent antioxidants with significant IC 50 values. The antimitotic studies such as mitotic index in onion root tips and sprouting assay in green gram seeds also proved that both the extracts are able to prevent mitosis. The extrapolation of these results can find opportunities in therapeutic regiments of cancer.","PeriodicalId":22829,"journal":{"name":"The Journal of Phytology","volume":"29 1","pages":"39-51"},"PeriodicalIF":0.0,"publicationDate":"2015-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76443365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are the vectors for the transmission of many viral pathogens and pose serious threat to human health. Chemical insecticides are widely used but they are non-selective and harmful to beneficial organisms. In the present study G. Sepium leaves extracts were used to analyse its effect against Aedes aegypti , to compare the mortality rate while using different solvent extracts of the leaf, to identify the solvent extract which give high rate of larval mortality and to characterise the compounds present in the corresponding leaf extract using phytochemical analysis. The ethanolic extract of G. sepium leaves constitute flavanoids, steroids, glycoside, carbohydrate and saponins compound. Thus it was found to have an inhibitory effect on the growth of larvae than other solvent extracts. In the statistical analysis highest significant difference was observed between 1.5g/l and 2.0g/l concentration of ethanolic extract and other extracts. However no significant difference was observed in other concentrations. The larvicidal activity of the plant extract may be attributed to the presence of active compounds like terpinoids, saponins and steroids.","PeriodicalId":22829,"journal":{"name":"The Journal of Phytology","volume":"1 1","pages":"26-31"},"PeriodicalIF":0.0,"publicationDate":"2015-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82891241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cereals form an integral part of human diet along with pulses, especially in India. Cereals contain a high percentage of carbohydrates along with the considerable amount of proteins. The present experiment was carried out to induce the variability in Hordeum vulgare L. variety RD-2035 and BH-393. The mutagen used in this experiment was hydrazine hydrate (Hz). The mutagen was used singly and in combination with dimethyl sulfoxide (DMSO). Usually, the DMSO is considered as a carrier for a mutagen to enhance the mutagenic activity of that particular mutagen used in combination. The two varieties of seeds were treated with individual concentrations of Hz along with combination treatments with DMSO. The seeds were sown to raise the M1 generation. Cytology of both control and treated plants was observed in the M1 generation. The control plants showed normal meiosis, whereas the treated plants showed different chromosomal abnormalities. The different chromosomal abnormalities were laggard, bridge, micronucleus, and univalents. The meiotic abnormalities were low at lower concentrations of both individual and combination treatments while as the percentage abnormalities increased with increasing concentrations of both individual and combination treatments. M1 seeds were sown to raise the M2 generation. Quantitative characters of both control and treated plants were observed. The lower concentrations of both individual and combination treatments induced desirable changes in quantitative characters while as the higher ones induced negative effects.","PeriodicalId":22829,"journal":{"name":"The Journal of Phytology","volume":"24 1","pages":"19-25"},"PeriodicalIF":0.0,"publicationDate":"2015-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78084696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
