MIDGET cooperates with COP1 and SPA1 to repress flowering in Arabidopsis thaliana.

Plant signaling & behavior - 1 Sept 2013

Schrader Andrea, Uhrig Joachim

Abstract excerpt

The life cycle of plants is strictly regulated by light, which directly influences the initiation of developmental programs such as photomorphogenesis of seedlings and induction of flowering. When environmental conditions are unsuitable, both processes are actively repressed by the action of COP1/SPA protein complexes which participate in ubiquitylation and subsequent degradation of transcription factors. We have...
