Transcript Dynamics at Early Stages of Molecular Interactions of MYMIV with Resistant and Susceptible Genotypes of the Leguminous Host, Vigna mungo
The present findings revealed an insight on the molecular warfare during host-virus interaction suggesting plausible signaling mechanisms and key biochemical pathways overriding MYMIV invasion in resistant genotype of V. mungo. Expand
An improved method of DNA isolation suitable for PCR-based detection of begomoviruses from jute and other mucilaginous plants.
The modification including use of more volume of extraction buffer and dissolving crude nucleic acid pellet in 1 M NaCl, reduced markedly the viscosity of the mucilage and thus in the final purification step yielded a larger quantity of mucilage-free DNA suitable for subsequent PCR-based detection of begomoviruses.

Molecular evidence for existence of a New World begomovirus associated with yellow mosaic disease ofCorchorus capsularis in India
Yellow mosaic disease of jute (Corchorus capsularis) was found to be associated with a whitefly-vectored begomovirus. Sequencing of part of the begomovirus DNA-A indicated the presence of a New WorldExpand
Isolation, Characterization, and Structure Analysis of a Non-TIR-NBS-LRR Encoding Candidate Gene from MYMIV-Resistant Vigna mungo
3D models of NBS and LRR regions of this candidate protein and MYMIV-coat protein revealed that CYR1-LRR forms an active pocket and successively interacts with MYM IV-CP during docking, indicating a critical role of CYR 1 as signalling molecule to protect V.mungo plants from MyMIV. Expand
Characterization of a temperature‐sensitive mutation that impairs the function of yeast tRNA nucleotidyltransferase
Comparative biophysical and biochemical characterization of both the wild‐type and variant proteins indicates that amino acid substitutions at this position can result in a structural change in the protein that reduces enzyme activity, decreases the melting temperature of the protein and alters its stability at the non‐permissive temperature.

Distribution, epidemiology and molecular variability of the begomovirus complexes associated with yellow vein mosaic disease of mesta in India.
A regression approach was adopted to consider the relationship of whitefly vector populations with weather conditions and disease spread which explained that different conducive weather factors facilitated the build up of white fly populations and contributed to the spread of the disease. Expand
The Micro-RNA172c-APETALA2-1 Node as a Key Regulator of the Common Bean-Rhizobium etli Nitrogen Fixation Symbiosis1[OPEN]
Increased miR172 resulted in improved root growth, increased rhizobial infection, increased expression of early nodulation and autoregulation of nodulation genes, and improved nodulations and nitrogen fixation. Expand
Identification and validation of conserved microRNAs along with their differential expression in roots of Vigna unguiculata grown under salt stress
18 conserved V. unguiculata miRNAs belonging to 16 distinct miRNA families are identified and found to be up-regulated during salt stress as revealed by quantitative real time PCR (qRT-PCR). Expand
Identification and expression profiling of Vigna mungo microRNAs from leaf small RNA transcriptome by deep sequencing.
MicroRNAs (miRNAs) represent a class of small non-coding RNA molecules that play a crucial role in post-transcriptional gene regulation. Several conserved and species-specific miRNAs have beenExpand
A Mutation in the Essential Gene gmk (Encoding Guanlyate Kinase) Generates a Requirement for Adenine at Low Temperature in Salmonella enterica
A model in which previously described regulatory effects of GMP are responsible for these phenotypes is proposed, in which the mutant enzyme had a more than 20-fold-higher Km for ATP than the wild-type enzyme. Expand
