Nitric oxide (NO) is a signaling molecule that affects a myriad of processes in plants. However, the mechanistic details are limited. NO post-translationally modifies proteins by S-nitrosylation of cysteines. The soluble S-nitrosoproteome of a medicinal, crassulacean acid metabolism (CAM) plant, Kalanchoe pinnata, was purified using the biotin switch(More)
Although in the last few years good number of S-nitrosylated proteins are identified but information on endogenous targets is still limiting. Therefore, an attempt is made to decipher NO signaling in cold treated Brassica juncea seedlings. Treatment of seedlings with substrate, cofactor and inhibitor of Nitric-oxide synthase and nitrate reductase (NR),(More)
Nitric oxide (NO), a new addition to plant hormones, affects numerous processes in planta. It is produced as a part of stress response, but its signaling is poorly understood. S-nitrosylation, a PTM, is currently the most investigated modification of NO. Recent studies indicate significant modulation of metabolome by S-nitrosylation, as the identified(More)
Nitric oxide (NO), a recent addition to the signaling molecules in plants, plays an important role in mediating both biotic and abiotic stress responses. The occurrence of reproductive/vegetative structures, known as epiphylly, on the surface of leaves is a stress survival mechanism exhibited by some plants, including Kalanchoe pinnata. In the present study(More)
Plant proteomics has made tremendous contributions in understanding the complex processes of plant biology. Here, its current status in India and Nepal is discussed. Gel-based proteomics is predominantly utilized on crops and non-crops to analyze majorly abiotic (49 %) and biotic (18 %) stress, development (11 %) and post-translational modifications (7 %).(More)
International Plant Proteomics Organization (INPPO) outlined ten initiatives to promote plant proteomics in each and every country. With greater emphasis in developing countries, one of those was to "organize workshops at national and international levels to train manpower and exchange information". This third INPPO highlights covers the workshop organized(More)
Nitric oxide (NO) has emerged as a key-signaling molecule affecting plant growth and development right from seed germination to cell death. It is now being considered as a new plant hormone. NO is predominantly produced by nitric oxide synthase (NOS) in animal systems. NOS converts L-arginine (substrate) to citrulline and NO is a byproduct of the reaction.(More)
