Silica and secondary metabolites as chemophenetic markers for characterization of bamboo species in relation to genetic and morphometric analysis.

Bamboo is a non-timber forest product and one of the most important grass plants of industrial and domestic use. It is widely distributed in tropical countries including India, China and Southeast Asian countries with wide genetic diversity. The diversity in the available genotypes becomes an important resource for the selection and improvement of the plants for ecological and commercial use.

Ecological restoration of coal fly ash-dumped area through bamboo plantation.

The present study entails the phytoremediation potential of different bamboo species on 5-year-old FA-dumped site near Koradi thermal power plant of Nagpur, Maharashtra, India. The selected FA-dumped site was treated with farmyard manure, press mud, and bio fertilizer followed by plantation of six promising species of bamboo namely Bambusa balcooa Roxb., Dendrocalamus stocksii (Munro.

Root transcripts associated with arsenic accumulation in hyperaccumulator Pteris vittata.

Hyperaccumulation of arsenic (As) by brake fern Pteris vittata has been described as an important genetic trait that provides an option for development of a sustainable phytoremediation process for As mitigation. Accumulation of very high concentration of arsenic in above-ground tissues may be the result of arsenic vacuole compartmentalization, but the mechanism(s) of arsenic uptake and transport by underground tissues are largely unknown. In this study, we made an attempt towards understanding the molecular mechanism of As hyperaccumulation in this plant.

Characterization of UDP-glucosyltransferase from Indigofera tinctoria.

Indican is a secondary metabolite in Indigofera tinctoria; its synthesis from indoxyl and UDP-glucose is catalyzed by a UDP-glucosyltransferase (UGT). In this study, we partially purified UGT extracted from I. tinctoria leaves and analyzed the protein by peptide mass fingerprinting.

Identification of arsenic resistant endophytic bacteria from Pteris vittata roots and characterization for arsenic remediation application.

Mitigation of arsenic (As) pollution is a topical environmental issue of high R&D priority. The present investigation was carried out to isolate As resistant endophytes from the roots of Indian ecotype Pteris vittata and characterize their As transformation and tolerance ability, plant growth promoting characteristics and their role to facilitate As uptake by the plant. A total of 8 root endophytes were isolated from plants grown in As amended soil (25 mg As kg(-1)).

RNA-Seq analysis for indigo biosynthesis pathway genes in Indigofera tinctoria and Polygonum tinctorium.

Natural indigo is the most important blue dye for textile dyeing and valuable secondary metabolite biosynthesized in Indigofera tinctoria and Polygonum tinctorium plants. Present investigation is made to generation of gene resource for pathway enrichment and to understand possible gene expression involved in indigo biosynthesis. The data about raw reads and the transcriptome assembly project has been deposited at GenBank under the accessions SRA180766 and SRX692542 for I.

Molecular docking and ADME studies of natural compounds of Agarwood oil for topical anti-inflammatory activity.

Aquilaria agallocha Roxb. family, Thymelaeaceae, is an evergreen plant of South-East Asia, commonly described as aloe wood or agarwood. Traditionally, the bark, root and heartwood are used for their medicinal properties as a folk medicine for hundreds of years.

Impact of geographic range on genetic and chemical diversity of Indian valerian (Valeriana jatamansi) from northwestern Himalaya.

An effort was made to determine the impact of geographic range on genetic richness and chemical constituents of Valeriana jatamansi Jones, an herb indigenous to the northwestern Himalaya. The genetic structure of 16 accessions from two major divisions of Uttarakhand state (Kumaon and Garhwal) was analyzed by ISSR markers. Overall genetic diversity among the populations was 45 %, with a cumulative range of 35-92 % similarity for most of the high-altitude plants and a comparatively narrow range, 50-88 %, for the population below the altitude of 1,800 m.

Molecular profiling for genetic variability in Capsicum species based on ISSR and RAPD markers.

The taxonomic identity of Capsicum species is found to be difficult as it displays variations at morpho-chemical characters. Twenty-two accessions of six Capsicum species, namely, C. annuum, C.

An efficient protocol for high-frequency direct multiple shoot regeneration from internodes of peppermint (Mentha x piperita).

A simple, repeatable and efficient protocol for direct multiple shoot regeneration from internodal explants has been defined in peppermint (Mentha x piperita var. Indus). In vitro regenerated shoots of peppermint were excised into 4 to 8 mm long internodes and cultured on Murashige and Skoog's medium supplemented with different cytokinins.

Genetic and chemical diversity of high mucilaginous plants of Sida complex by ISSR markers and chemical fingerprinting.

A method was developed based on multiple approaches wherein DNA and chemical analysis was carried out toward differentiation of important species of Sida complex that is being used for commercial preparation. Isolated DNA samples were successfully performed through PCR amplification using ISSR markers and degree of genetic diversity among the different species of Sida is compared with that of chemical diversity. For genetic fingerprint investigation, selected 10 ISSR primers generating reproducible banding patterns were used.
