Comprehensive analysis of GGCT genes in u's triangle Brassica species: insights into abiotic stress responses and potential association of BnaGGCT11/26 with seed weight.

ABSTRACT:

Background

Glutathione homeostasis, crucial for plant growth and stress adaptation, is regulated by the enzyme γ-glutamylcyclotransferase (GGCT). As the critical component of the glutathione recycling pathway, GGCT plays a vital role in maintaining cellular redox balance under normal and stressful conditions. While the GGCT gene family has been characterized in Arabidopsis thaliana, its diversity, evolution, and functional roles remain unexplored in the U's triangle Brassica species, which includes important oilseed crops.

Results

We identified and characterized 154 putative GGCT genes in U's triangle Brassica species (Brassica nigra, 20; Brassica oleracea, 21; Brassica rapa, 18; Brassica juncea, 35; Brassica napus, 31; Brassica carinata, 29). Phylogenetic analysis grouped t
