Dynamic profile of gene expression in rice flag leaf under high temperature

ABSTRACT: To comprehend the profile of rice gene expression at reproductive stage under high temperature, Agilent 4x44k rice oligo microarray experiments were carried out using rice panicle of developmental stage 7-9 at 0min, 10min, 20min, 60min, and 2hr after the treatment of 40 degree centigrade, and the significantly expressed genes mainly involved in transcriptional regulation, transport, cellular homeostasis, and stress response were identified. Among them, the predominant transcription factor gene families were Hsf, NAC, AP2/ERF, WRKY, MYB, and C2H2. KMC analysis discovered the time-dependent gene expression pattern under heat. The results of motif co-occurrence on the promoters of genes from an early up-regulated cluster showed the important roles of GCC box, HSE, ABRE, and CE3, and unraveled
