Genome-wide identification, transcriptome analysis and alternative splicing events of Hsf family genes in maize.

ABSTRACT: Heat shock transcription factor (Hsf) plays a transcriptional regulatory role in plants during heat stress and other abiotic stresses. 31 non-redundant ZmHsf genes from maize were identified and clustered in the reference genome sequenced by Single Molecule Real Time (SMRT). The amino acid length, chromosome location, and presence of functional domains and motifs of all ZmHsfs sequences were analyzed and determined. Phylogenetics and collinearity analyses reveal gene duplication events in Hsf family and collinearity blocks shared by maize, rice and sorghum. The results of RNA-Seq analysis of anthesis and post-anthesis periods in maize show different expression patterns of ZmHsf family members. Specially, ZmHsf26 of A2 subclass and ZmHsf23 of A6 subclass were distinctly up-regulated after h
