Indigenous knowledge plays a vital role in assessing the trend of evolution of human civilization; hence documentation of local uses of plants and traditional practices developed through use of human intellect now has become an important activity due to implementation of various issues related to Convention on Biological Diversity (CBD), Intellectual Property Rights (IPR), etc. Keeping this in view, an attempt has been made to document indigenous knowledge on fibre extraction of sunnhemp still practiced in some pockets among the tribal communities of Bundelkhand region, reflecting to preserve the age old tradition of farming communities residing there.

The present study confirms the occurrence of Chilli veinal mottle virus (ChiVMV) under the genus Potyvirus in Naga chilli (Capsicum chinense) in Meghalaya based on mechanical transmission assay, transmission electron microscopy, RT-PCR and sequence analysis. This is the first record of Chivmv in Naga chilli in North-East India. © 2013, Indian Virological Society. Source

Basal stem rot (BSR) is an important disease caused by Ganoderma lucidum in economically important palms and forest trees. Thirty-five isolates were collected from all over India under different agroclimatic zones from different hosts and these isolates were characterized for cultural, phenotypical and molecular variations. The colony colour range from white to pale yellow or yellow. The aerial mycelium consist mostly thin walled, branched hyphae with clamp connections. Some isolates showed sparse mycelial growth and chlamydospore formation on the PDA medium. Amongst the three liquid media tested for growth of G. lucidum, the potato dextrose broth was significantly superior to other Waksman media and Glucose special media in the order of importance. Lignin degrading enzyme laccase activity was observed higher on fast growing isolates followed by medium and slow growing G. lucidum isolates. Molecular variability studies were also done with six random primers after preliminary screening with thirty random primers to group the G. lucidum isolates. All the slow growing isolates and few medium growing G. lucidum isolates were grouped in cluster A, but all the fast growing isolates were grouped in cluster B to G. Source

The grain and flour characteristics of different field pea (FP) accessions were evaluated. Accessions with higher grain weight had less compact structure with a greater proportion of large-sized starch granules. Accessions with higher protein content had lower starch content, blue value and λmax whereas accessions with higher amylose showed higher resistant starch (RS) and final viscosity and lower rapidly digestible starch (RDS). Ca, Zn, K and Fe content vary significantly amongst different accessions and creamish green and white seeds accessions showed higher Fe and Zn content. Yellow coloured accessions (1.36-3.71%) showed lower antioxidant activity as compared to brownish and green coloured accessions (4.06-9.30%). Out of 21 major polypeptides observed (9-100 kDa), 11 showed differential trypsin inhibitory activity (TIA) under non-reducing conditions. Polypeptides of 68, 46, 33 and 22 kDa showed prominent TIA. © 2014 Published by Elsevier Ltd. Source

Pomegranate (Punica granatum L.) is one of the oldest known edible fruit tree species, originating in Central Asia, but with a wide geographical global distribution, reflecting its adaptation to a wide range of climatic conditions. It is important for its nutritional, medicinal and ornamental properties and its high consumption and industrial value. In a bid to better utilize and improve the current genetic resources, there is a need to understand and appreciate studies related to the use, centre of origin and diversity, as well as the characterization, evaluation and conservation, taxonomy and systematics of the genus Punica. In addition to understanding the basic biology of the plant, how biotechnological tools, including cell and tissue culture and micropropagation (i.e. somatic embryogenesis, organogenesis, synthetic seeds, somaclonal variation, mutagenesis, haploidy, and in vitro conservation), genetic transformation and marker technology, have been used to improve pomegranate germplasm are all topics that have been covered in this review. © 2013 Elsevier B.V.
