Genome-wide analysis of DC1 domain proteins in Ipomoea species reveals IbCHR10 as a positive regulator of salt tolerance in sweet potato

This study provides a systematic characterization of DC1 domain (CHR) proteins in <i>Ipomoea</i> species and identifies IbCHR10 as an important regulator associated with salt stress tolerance, offering valuable genetic resources for developing stress-resilient sweet potato cultivars.
