Analysis of heat shock protein 70 gene family in Capsicum chinense Jacq.

Based on genomic data of Capsicum chinense Jacq., whole genome identification of the HSP70 gene family was carried out using bioinformatics. In total, 20 HSP70 genes were identified, with coding protein length ranging from 516 to 854 aa and molecular weight ranging from 56.21 to 94.26 kD. Phylogenetic analysis showed that the HSP70 gene family was divided into three subfamilies:A, B, and C. Comparative transcriptome analysis showed that 16 HSP70 genes were responsive to heat stress.
