Auxin-independent NAC pathway regulates cell wall metabolism in response to explant-specific wounding during regeneration in Arabidopsis II

ABSTRACT: In this study, through a genome-wide transcriptome analysis of wounding in the leaf explant, we identified NAC1 (petunia NAM and Arabidopsis ATAF1, ATAF2, and CUC2) family transcription factor gene that acts in response to wounding and functions in regulation of cell wall metabolism.

A novel NAC transcription factor cooperates with bZIP-type transcription factors in dehydration and osmotic stress responses

Project description:Multiple transcription factors (TFs) play essential roles in plants under abiotic stress, one of the most challenging conditions of plant survival. However, how these multiple TFs cooperate in abiotic stress responses still remains largely unknown. In this study, we provide evidence that a novel NAC (NAM, ATAF1/2, and CUC2) transcription factor (ANAC096) cooperates with bZIP-type TFs [ABRE-binding factor/ABRE-binding protein (ABF/AREB)] in ensuring survival under dehydration and osmotic stress conditions. Intriguingly, ANAC096 directly interacted with ABF2 and ABF4, but not with ABF3, both in vitro and in vivo. ANAC096 and ABF2 synergistically activated RD29A transcription. The genome-wide gene expression analysis revealed that a major proportion of ABA-responsive genes are under the transcriptional regulation of ANAC096.An Arabidopsis mutant, anac096, was hyposensitive to exogenous abscisic acid (ABA), and showed impaired ABA-induced stomatal closure and increased water loss under dehydration stress conditions. Furthermore, the anac096 abf2 abf4 triple mutant was much more sensitive to dehydration and osmotic stresses than the anac096 single mutant or the abf2 abf4 double-mutant. Based on these results, we propose that ANAC096 is involved in a synergistic relationship with a subset of ABFs for the transcriptional activation of ABA-inducible genes in response to dehydration and osmotic stresses.

mRNA transcription profile of potato (Solanum tuberosum L.) in response to explant cutting

Project description:The explant is likely the most essential parameter of plant tissue culture. The vast majority of tissue culture studies have focused almost exclusively on the use of explants as a tool for organogenesis or propagation, and there is limited information that documents the changes that occur in an explant in response to cutting during explant preparation just prior to culture. To better understand the molecular changes occurring during the wounding process that accompanies the preparation of an explant, this study examined the mRNA transcription profile of potato (Solanum tuberosum L. cv. Desirée) single-node segments. To achieve this, RNA-seq analysis was performed to identify significantly differentially expressed genes (DEGs) that existed between uncut in vitro plantlets and cut explants. DEGs were connected to cellular processes in the extracellular region, nucleus, and plasma membrane, and were associated with biosynthesis, carbohydrate metabolism and catabolism, cellular protein modification, growth and development, and response to stress. These results provide a novel perspective of the changes taking place within explants when they are cut and serve as a valuable basis for the study of explant-related stress in plant tissue culture in other plant species, and may provide an understanding of the success or failure of the tissue culture protocol and subsequent establishment of in vitro cultures.

Overexpression of OsNAC14 improves drought tolerance in rice

Project description:Plants have evolved to possess adaptation mechanism to cope with drought stress by reprograming transcriptional networks through drought responsive transcription factors, which in turn mediate morphological and physiological changes. NAM, ATAF1-2, and CUC2 (NAC) transcription factors are known to be associated with various developmental processes and stress tolerance. In this study, we functionally characterized the rice drought responsive NAC transcription factor OsNAC14. OsNAC14 was predominantly induced at meiosis stage, and induced by drought, high salinity, ABA and low temperature in leaves than roots. Overexpression of OsNAC14 resulted in drought tolerance at the vegetative growth stage and enhanced filling rate at vegetative growth. OsNAC14 overexpression elevated expression of genes related to DNA damage repair, defense response, strigolactone biosynthesis, which correlated with resistance to drought tolerance. Furthermore, OsNAC14 directly bound to the promoter of drought inducible OsRAD51A1, a key component in homologous recombination in DNA repair system. These results indicate that OsNAC14 mediate drought tolerance by recruiting factors involved in DNA damage repair and defense response to enable plant to protect from cellular damage caused by drought stress, thereby provide mechanism for drought tolerance.
