Plant often responds to fungal pathogens by expressing a group of proteins known as pathogenesis-related proteins (PRs). The expression of PR is mediated through pathogen-induced signal-transduction pathways that are fine-tuned by phytohormones such as methyl jasmonate (MeJA). Here, we report functional characterization of an Ocimum basilicum PR5 family member (ObTLP1) that was identified from ...

A cDNA clone encoding a basic thaumatin-like protein of Zea mays was recovered from a mid-development seed cDNA library. The gene, Zlp, encoded a protein that was nearly identical with maize zeamatin and alpha-amylase/trypsin inhibitor. Expression of Zlp mRNA was highest in the endosperm tissue of seed 4 weeks after pollination. Expression of zeamatin-like (ZLP) protein correlated with mRNA; al...

Gymnema sylvestre(G. sylvestre) (Asclepiadaceae) commonly known as ‘Gudmar’ in Hindi is an important medicinal plant (Climber) used in different systems of medicine as a remedy for the treatment of diabetes, rheumatism, cough, ulcer, jaundice, dyspepsia, constipation, eyes pain and also in snakebite. The major phytoconstituents of gymnema sylvestra are gymnemic acids, gudmarin and saponins[1]. ...

The T1R taste receptors, like other type 3 G-protein-coupled receptors (GPCRs), have a large amino terminal extracellular domain. Type 3 GPCRs typically function as dimers, but each monomer can independently bind ligand. Based on studies with the metabotropic glutamate receptors (mGluRs) the site for ligand binding in type 3 GPCRs is thought to be in a shell-like cleft formed by two lobes withi...

During ripening of grape (Vitis labruscana L. cv Concord) berries, abundance of several proteins increased, coordinately with hexoses, to the extent that these became the predominant proteins in the ovary. These proteins have been identified by N-terminal amino acid-sequence analysis and/or function to be a thaumatin-like protein (grape osmotin), a lipid-transfer protein, and a basic and an aci...

Excess manganese (Mn) supply causes formation of visible brown depositions in the cell walls of leaves of cowpea (Vigna unguiculata), which consist of oxidized Mn and oxidized phenols. Because oxidation of Mn and phenolic compounds in the leaf apoplast was proposed to be catalyzed by apoplastic peroxidases (PODs), induction of these enzymes by Mn excess was investigated. POD activity increased ...

White rust, caused by Albugo candida, is a serious pathogen of Brassica juncea (Indian mustard) and poses a potential hazard to the presently developing canola-quality B. juncea industry worldwide. A comparative proteomic study was undertaken to explore the molecular mechanisms that underlie the defence responses of Brassica juncea to white rust disease caused by the biotrophic oomycete Albugo ...
