Comprehensive Genomic Analysis and Expression Profile of Hsp70 Gene Family Related to Abiotic and Biotic Stress in Cucumber

Heat shock protein 70 (Hsp70) is a class of HSPs involved in plant growth and development, stress response regulation. The Hsp70 proteins exist widely the world, but detail information about Hsp70s still unclear cucumber. Based on available cucumber genome, total 12 genes (CsHsp70-1 to CsHsp70-12) were identified this study, they distributed among five out seven chromosomes. CsHsp70s divided into four groups based phylogenetic analysis by using sequences from other plants, their conserved motifs relatively conserved. Gene duplication showed that segmental main driving force expansion CsHsp70 genes. Promoter contained many cis-acting elements hormone responses. Expression RNA-seq qRT-PCR indicated expression most was associated with multiple biotic abiotic stresses This study introduces characteristics regulation levels various stresses, which provided basis for functional exploration utilization future.
