Overexpressing a NAM, ATAF, and CUC (NAC) transcription factor enhances drought resistance and salt tolerance in rice.
Drought and salinity are major abiotic stresses to crop production. Here, we show that overexpression of stress responsive gene SNAC1 (STRESS-RESPONSIVE NAC 1) significantly enhances drought resistance in transgenic rice (22-34% higher seed setting than control) in the field under severe drought stress conditions at the reproductive stage while showing no phenotypic changes or yield penalty. Th...
متن کاملNAC transcription factor JUNGBRUNNEN1 enhances drought tolerance in tomato
Water deficit (drought stress) massively restricts plant growth and the yield of crops; reducing the deleterious effects of drought is therefore of high agricultural relevance. Drought triggers diverse cellular processes including the inhibition of photosynthesis, the accumulation of cell-damaging reactive oxygen species and gene expression reprogramming, besides others. Transcription factors (...
متن کاملImproved drought and salt tolerance in transgenic Arabidopsis overexpressing a NAC transcriptional factor from Arachis hypogaea.
The NAC (NAM, ATAF, and CUC) proteins share a highly conserved NAC domain and constitute a large family of plant-specific transcriptional factors. We have isolated a drought-induced NAC gene from Arachis hypogaea, named AhNAC2 (Arachis hypogaea NAC2) but its specific role remains unknown. In this study, we found that transgenic Arabidopsis overexpressing AhNAC2 lines were hypersensitive to ABA ...
متن کاملOverexpression of a Stress-Responsive NAC Transcription Factor Gene ONAC022 Improves Drought and Salt Tolerance in Rice
The NAC transcription factors play critical roles in regulating stress responses in plants. However, the functions for many of the NAC family members in rice are yet to be identified. In the present study, a novel stress-responsive rice NAC gene, ONAC022, was identified. Expression of ONAC022 was induced by drought, high salinity, and abscisic acid (ABA). The ONAC022 protein was found to bind s...
متن کاملImproving Rice (Oryza sativa L.) Drought Tolerance by Suppressing a NF-YA Transcription Factor
The response to drought stress is a complicated process involving stress sensing, intracellular signaltransduction, and the execution of a cellular response. Transcription factors play important roles in the signaling pathways including abiotic stress. In the present study a rice NF-YA transcription factor gene was partially characterized following dehydration. Disrupting the gene via a T...
