Genome-Wide Identification of the Sulfate Transporter Gene Family Reveals That <i>BolSULTR2;1</i> Regulates Plant Resistance to <i>Alternaria brassicicola</i> Through the Modulation of Glutathione Biosynthesis in Broccoli.

ABSTRACT: Sulfate transporters (SULTRs) are key players that regulate sulfur acquisition and distribution within plants, thereby influencing cellular redox hemostasis under pathogen attacks, such as Alternaria brassicicola (Ab). In this study, a total of 23 BolSULTR (Brassica oleracea SULTR) genes were identified from the Brassica genome. These BolSULTRs are distributed across nine chromosomes, with all collinear BolSULTR gene pairs undergoing purifying selections. Phylogenetic analysis reveals that the SULTR family is evolutionarily conserved among plant kingdoms. qRT-PCR analysis demonstrated that the expression of BolSULTRs varies across different plant organs and is modulated by hormonal signals. Furthermore, transcriptome analysis identifi
