Rice NAC transcription factor ONAC066 functions as a positive regulator of drought and oxidative stress response.

ABSTRACT:

Background

NAC (NAM, ATAF and CUC) transcriptional factors constitute a large family with more than 150 members in rice and several members of this family have been demonstrated to play crucial roles in rice abiotic stress response. In the present study, we report the function of a novel stress-responsive NAC gene, ONAC066, in rice drought and oxidative stress tolerance.

Results

ONAC066 was localized in nuclei of cells when transiently expressed in Nicotiana benthamiana and is a transcription activator with the binding ability to NAC recognition sequence (NACRS) and AtJUB1 binding site (JBS). Expression of ONAC066 was significantly induced by PEG, NaCl, H₂O₂ and abscisic acid (ABA). Overexpression of ONAC066 in transgenic rice improved drought and oxida
