Abstract With the rapid development of modern molecular biology and bioinformatics, many studies have proved that transcription factors play an important role in regulating the growth and development of plants. SPATULA (SPT) belongs to the bHLH transcription family and participates in many processes of regulating plant growth and development. This review systemically summarizes the multiple roles of SPT in plant growth, development, and stress response, including seed germination, flowering, leaf size, carpel development, and root elongation, which is helpful for us to better understand the functions of SPT.

Abstract It is known that the high level of sugar including glucose suppresses seed germination through ABA signal. ABI5 is an essential component to mediate ABA-dependent seed germination inhibition, but underlying mechanism needs more investigation. Previous study demonstrated the PIF4 activated the expression of ABI5 to suppress seed germination in darkness. Here we reported that PIF4 also mediated the seed germination inhibition through ABI5 under high concentration of glucose treatment. Furthermore, we found that PIF4 interacted with PAP1, the central factor to control anthocyanin biosynthesis. Such interaction was confirmed in vitro and in planta. Biochemical and physiological analysis revealed that PAP1… More >
