Research progress on mechanisms of FHY3/FAR1 transcription factors in plants
FHY3(FAR-RED ELONGATED HYPOCOTYL 3)and its homologous protein FAR1(FAR-RED IM-PAIRED RESPONSE 1)are widely regarded as two important transcription factors of classical light signal transduction pathway.Three domains consist of a typical FHY3/FAR1 protein family,which is N-terminal C2H2 zinc-finger domain,C-terminal SWIM zinc-finger domain and a core transposase domain respective-ly.FHY3/FAR1 transcription factor family is involved in several developmental processes and responses to environmental stress,which means it plays an important role in the maintenance of plant homeostasis.In this review,we summarized research progress of FHY3/FAR1 family in recent years,and discussed more possibilities in plant stress responses.We hope this article would lay theoretical foundation for further ex-ploring molecular mechanisms of FHY3/FAR1 family responding to environmental stress.
