Abstract
This entry represents a group of plant Myb domain proteins, including LUX, BOA and MYBC1 from Arabidopsis. LUX and BOA are transcription factors and critical components of the regulatory circuit of the circadian clock [ 1 , 2 ]. LUX also binds to ELF3 and associates with ELF4 in a diurnal complex which is required for the expression of the growth-promoting transcription factors PIF4 and PIF5 and subsequent hypocotyl growth in the early evening [ 3 ]. MYBC1 has been shown to negatively regulate freezing tolerance in Arabidopsis [ 4 ].
