Steroid alkaloids (SAs) and their glycosylated forms (steroidal glycoalkaloids, SGAs) are a group of specialized metabolites widely present in Solanaceae plants, which have defense effects against plant pathogens and herbivores. So far, nearly 100 types of steroid alkaloids have been detected in tomato.
Recently, the team led by Shouchuang Wang from Hainan University published a research paper titled "SlERF.H6 mediates the orchestration of ethylene and gibberellin signaling that suppresses bitter-SGAs biosynthesis in tomato". In this study, an AP2/ERF transcription factor, SlERF.H6, was identified using forward genetics and genome-wide association analysis, and its key role in regulating the biosynthesis of SGAs by mediating crosstalk between ethylene and gibberellin signaling pathways was elucidated.
This study not only provides new insights into the regulation mechanism of SGAs, but also provides a reference for using various technologies to cultivate superior tomato varieties.
