Genome-Wide Analysis of the Thiamine Biosynthesis Gene Families in Common Bean Reveals Their Crucial Roles Conferring Resistance to Fusarium Wilt.

ABSTRACT: Fusarium wilt, caused by Fusarium oxysporum f. sp. phaseoli (Fop), is a major constraint to global common bean (Phaseolus vulgaris L.) production. Thiamine (vitamin B1), an essential coenzyme in plant metabolism, has recently emerged as a potential regulatory factor in plant defense. Here, we performed a comprehensive genome-wide analysis of thiamine biosynthesis-related genes in common bean and elucidated their roles in resistance to Fusarium wilt. Five key thiamine biosynthetic genes were identified and characterized, showing conserved functional domains and evolutionary conservation across species. Expression profiling revealed tissue-specific patterns, with PvTHI1-1 and PvTHIC being highly expressed in reproductive and photosynthetic organs, with thei
