Dimerization and blue light regulation of PIF1 interacting bHLH proteins in Arabidopsis.

Plant molecular biology - 1 Nov 2011

Abstract excerpt

Phytochrome Interacting Factor 1 (PIF1), a basic helix-loop-helix (bHLH) protein, functions as a negative regulator of various facets of photomorphogenesis. To indentify PIF1-interacting proteins, we performed yeast two-hybrid screening using PIF1 as a bait and identified a group of proteins including PIF1 itself, PIF3 and long hypocotyl in far-red 1 (HFR1), an atypical HLH protein. Directed yeast two-hybrid...
