FUNCTIONING OF DIFFERENT PLANT HEAT-SHOCK PROTEINS IN MAIZE (ZEA MAYS) AND MOLECULAR CHAPERONES - AN INSIGHT

摘要

Biotic and abiotic stresses like temperature, drought, herbivores, salinity, chemical pollutants, pathogens etc affect or interfere in the normal growth of maize growth, leading to yield reduction. Series of molecular responses shows by maize to thesestresses. Because of elevated temperature exposure the induction and production of heat-shock protein (HSP) are common phenomena in crop plant like maize {Zea mays). Heat-shock proteins are ubiquitous protein present within all studied cell organisms. Expression of a family of genes together with other stresses induces by heat referred as the HSP genes. Heat tolerance in maize include comprehensively an orderly, complex and dynamic regulatory system of other groups of HSPs, data are present on the connection maintenance and induction of HSPs under high temperature with improved heat tolerance in maize. Plants experiencing high-temperature stress is well known expressed as HSPs. HSPs called so due to their expression behavior or similarity of sequenceto other HSP genes.
