Résumé
Abscisic acid (ABA) and the AP2/ERF (APETALA 2/ETHYLENE-RESPONSIVE FACTOR)-type transcription factor ABA INSENSITIVE 4 (ABI4) control plant growth and development. We review how singlet oxygen, which is produced in chloroplasts of the fluorescent mutant of Arabidopsis thaliana (arabidopsis), and ABI4 may cooperate in transcriptional and translational reprogramming to cause plants to halt growth or demise. Key elements of singlet oxygen- and ABI4-dependent chloroplast-to-nucleus retrograde signaling involve the chloroplast EXECUTER (EX) 1 and EX2 proteins as well as nuclear WRKY transcription factors. Mutants designed to study singlet oxygen signaling, that lack either ABI4 or the EX1 and EX2 proteins, do not show most of the growth effects of singlet oxygen. We propose a model that positions ABI4 downstream of WRKY transcription factors and EX1 and EX2.
