Interplay of rice vitamin E under osmotic and extreme temperature stresses revealed by a comparative transcriptomic approach.

ABSTRACT:

Background

Rice (Oryza sativa L.) is vulnerable to abiotic challenges. Understanding stress response mechanisms is therefore a priority for enhancing rice development. Tocopherol is a known antioxidant that helps plants adapt to various abiotic stresses. We analysed bibliographic data from 13 years of studies on abiotic stresses. We also performed a meta-analysis of 231 microarray samples from 12 different studies on genotypes sensitive and tolerant to drought, salinity, heat, and heat-related effects on vitamin E biosynthesis in rice. Common differentially expressed genes (DEGs - 30) were identified with p-value < 0.05 and |log₂FC| > 1. An in silico expression analysis of the DEGs and a Protein-Protein Interaction (PPI) network analysis were performed using bioinformati
