TL;DR
This study identifies and characterizes the HSP70 gene family in carrot, revealing their evolutionary relationships and roles in stress response.
Contribution
The first comprehensive genome-wide analysis of the HSP70 gene family in carrot (Daucus carota L.).
Findings
52 DCHSP70 genes were identified and classified into six phylogenetic subgroups.
Segmental duplication and purifying selection were key in the evolution of the DCHSP70 gene family.
Promoter analysis revealed stress-responsive regulatory elements, suggesting roles in environmental adaptation.
Abstract
Heat-shock protein 70 (HSP70) chaperones play indispensable roles in protein folding, homeostasis, and protecting plants against abiotic stress. While well-characterized in model species, a comprehensive genome-wide analysis of the HSP70 family in carrot (Daucus carota L.) has been lacking. The study aimed to identify the DCHSP70 gene family members in the Daucus carota genome and elucidate their evolutionary relationships, structural characteristics, and potential functional roles under stress conditions. We performed a systematic genome-wide analysis using bioinformatic approaches to identify family members. Phylogenetic relationships were analyzed using neighbor-joining methods, while chromosomal distribution and synteny were visualized to track evolutionary analysis. Promoter regions were screened for cis-regulatory elements, and protein-protein interaction (PPI) networks were…
