title: Chromatin modification and remodelling: a regulatory landscape for the control of Arabidopsis defence responses upon pathogen attack.
abstract: Due to their sessile lifestyle, plants have to cope with an ever-changing environment and to defend themselves against a multitude of biotic aggressors that compromise their development and reproduction. Responses to various biotic stresses largely depend on the plant's capacity to modulate rapidly and specifically its transcriptome. In a stress type-dependent manner, external signals are translocated into the nucleus to activate transcription factors, resulting in the increased expression of particular sets of defence-related genes. Among mechanisms of transcriptional regulation, chromatin remodelling accomplished through the activity of histone-modifying enzymes and ATP-dependent chromatin-remodelling complexes is emerging as a key process in the orchestration of plant biotic stress responses. In this review, we summarize and discuss roles that chromatin-remodelling mechanisms may play in regulating Arabidopsis defence responses.
