摘要: Reactive oxygen species (ROS) are produced when plants exposed to environmental stresses, such as drought and heat conditions. Oxidative stress imposed by ROS under conditions profoundly affects plant growth development. However, production scavenging mechanisms adverse largely unknown. We have recently reported that a NAM/ATAF1/2/CUC2 (NAC) transcription factor NTL4 is required for generation of in Arabidopsis. 35S:4ΔC transgenic overexpressing truncated form (4ΔC) lacking the C‑terminal transmembrane (TM) motif were hypersensitive stress, accumulated high level plants. In contrast, NTL4-deficient ntl4 mutants less sensitive contained reduced levels ROS. Furthermore, plasma membrane-associated proteolytically activated treatments with abscisic acid (ABA) nuclear-localized, where it ...
