Mitogen activated protein kinase (MAPK) cascade is an important signaling cascade that operates in stress signal transduction in plants. The biologically active monoterpenoid indole alkaloids (MIA) produced in Catharanthus roseus are known to be induced under several abiotic stress conditions such as wounding, UV-B etc. However involvement of any signaling(More)
Protein-protein interaction is one of the crucial ways to decipher the functions of proteins and to understand their role in complex pathways at cellular level. Such a protein-protein interaction network in many crop plants remains poorly defined owing largely to the involvement of high costs, requirement for state of the art laboratory, time and labour(More)
The root system is an imperative component of a plant, involved in water and nutrient acquisition from the soil. Any subtle change in the root system may lead to drastic changes in plant productivity. Both auxin and cytokinin are implicated in regulating various root developmental aspects. One of the major signaling cascades facilitating various hormonal(More)
The canonical mitogen activated protein kinase (MAPK) signaling pathway plays a vital role in carrying out the normal growth and development of the plant. The pathway, connecting the upstreams signal with the downstream target is considered to be linear, mostly starting with a MAPKKK and ending in a MAPK. Here we report a novel interaction between two rice(More)
Mitogen-activated protein kinase (MAPK) signal transduction networks have been extensively explored in plants; however, the connection between MAPK signaling cascades and submergence tolerance is currently unknown. The ethylene response factor-like protein SUB1A orchestrates a plethora of responses during submergence stress tolerance in rice (Oryza sativa).(More)
Ultra violet radiation leads to accumulation of phytoalexins (PA) in rice (Oryza sativa) which are typically accumulated when the plants are infected with rice blast pathogen Magnaporthe oryzae. Although extensive works have been done in elucidating phytoalexin biosynthesis, UV stress signal transduction leading to accumulations of rice phytoalexin is(More)
Mitogen-activated protein kinase (MAPK) signaling cascade has been extensively studied in plants. Recently, this important network has been implicated in imparting submergence tolerance by facilitating the phosphorylation of the SUB1A1 protein. In this study, we try to examine the speculative role of MAPK cascade components in another rice mega-variety Pusa(More)
A 19-year-old man presented with unilateral sudden onset vision loss following an intra-articular triamcinolone injection in the right temporomandibular joint. At fundus examination emboli of triamcinolone were visible in multiple retinal arteries. Choroidal ischaemia and occlusion of the central retinal artery and its branches were documented at(More)
Plant physiology, in particular, is governed by a repertoire of endogenous as well as environmental cues. Auxin and cytokinin constitute an indispensable phytohormonal system required for plant growth and development. Another pivotal aspect of plant physiological process that thoroughly affects various plant growth and developmental attributes is the(More)
Increased level of Ultra violet-B radiation at earth’s surface has several deleterious consequences for plants and ecosystems. Higher UV-B level affects crop plants in several ways and also gives penalty in terms of crop yield. With changing climatic conditions it is crucial to elucidate signal transduction pathway involved in UV-B stress. Here, involvement(More)
