Quantitative iTRAQ-based proteomic analysis of rice grains to assess high night temperature stress.

ABSTRACT: Rice yield and quality are adversely affected by increasing global surface temperature, and are strongly attributed to high night temperature (HNT) than high daytime temperature. However, the molecular mechanism underlying the heat-tolerant characteristics of rice remains unclear. In the present study, we compared the proteomes of heat-tolerant and -sensitive lines of rice at early milky stage using an iTRAQ method. We have identified 38 differentially expressed proteins between the two lines, of which 32 proteins have been functionally annotated in NCBI and/or the UniProt database. These proteins were then classified into seven functional subgroups, which include signal transduction, transcript regulation, oxidation, defense response, transport, energy metabolism, and biosynthesis.
