Brief bio: I started my PhD study and accepted systematic scientific training in Ming-Yi Bai’s laboratory of Shandong University. Since then, I have focused on the function of the transcription factor HBI1. We found that the expression of HBI1 and its homologous gene BEE2 was induced by nitrate. We further proved that mutations of HBI1 and its three most homologous (HBIs) weaken the sensitivity of plants to nitrate in terms of growth and gene expression. HBIs induces the expression of a set of antioxidant genes and reduces the content of reactive oxygen species in plants, while reactive oxygen species and nitrate nitrate antagonize the subcellular localization of NLP7, a key transcription factor that regulates nitrate signal transduction, thereby regulating downstream gene expression and plant growth and development.
