“…4a and Supplementary Table 22). PSGs in the D subgenome such as RCD1 and NAC transcription factor genes 46 are predicted to facilitate fiber development by regulating abiotic stress tolerance. These data suggest that fiber-related genes in the A subgenome contribute to fiber improvement, which is consistent with the phenotype in the A progenitor but not in the D progenitor.…”

“…7). The NAC domain-containing proteins are involved in the regulation of stress tolerance (Puranik et al, 2012). Inhibition of bud outgrowth by shade signals in Arabidopsis is associated with increased expression of genes involved in ABA biosynthesis/response in plants ( González-Grandío et al, 2013;Reddy et al, 2013).…”

Phytochrome B (phyB) enables plants to modify shoot branching or tillering in response to varying light intensities and ratios of red and far-red light caused by shading and neighbor proximity. Tillering is inhibited in sorghum genotypes that lack phytochrome B (58M, phyB-1) until after floral initiation. The growth of tiller buds in the first leaf axil of wild-type (100M, PHYB) and phyB-1 sorghum genotypes is similar until 6 d after planting when buds of phyB-1 arrest growth, while wild-type buds continue growing and develop into tillers. Transcriptome analysis at this early stage of bud development identified numerous genes that were up to 50-fold differentially expressed in wild-type/phyB-1 buds. Up-regulation of terminal flower1, GA2oxidase, and TPPI could protect axillary meristems in phyB-1 from precocious floral induction and decrease bud sensitivity to sugar signals. After bud growth arrest in phyB-1, expression of dormancy-associated genes such as DRM1, GT1, AF1, and CKX1 increased and ENOD93, ACCoxidase, ARR3/6/9, CGA1, and SHY2 decreased. Continued bud outgrowth in wild-type was correlated with increased expression of genes encoding a SWEET transporter and cell wall invertases. The SWEET transporter may facilitate Suc unloading from the phloem to the apoplast where cell wall invertases generate monosaccharides for uptake and utilization to sustain bud outgrowth. Elevated expression of these genes was correlated with higher levels of cytokinin/sugar signaling in growing buds of wild-type plants.

“…The regulation of NAC transcription factors depend on the environmental condition. Approximately 20 to 25% of NAC transcription factor genes are expressed in response to one type of abiotic or biotic stress [5]. NAC transcription factor has excessive role in plant metabolic activity during any change to transcribe different genes, which are responsible for that influential factor.…”

Grapevine is an economically important crop throughout the world. However commonly cultivated species Vitis vinifera is susceptible to powdery mildew fungi. The objective of this study was to analyze the promoter of VvNAC36 transcription factor gene, which was induced by powdery mildew infection, as it was shown by previous microarray results. Analysis of VvNAC36 transcription factor promoter allows identifying the important cis-elements, which are responsible for gene regulation during infection. Knowing that the responsible cis-element of the gene is crucial for further study, the role of this gene is in powdery mildew infected grapevine. The study was performed using circumspect methodology. To confirm the presence of transgene in transgenic plants the PCR and glufosinate total herbicide application was used. The transplanted transgenic seedlings were infected with Golovinomyces orontii. To detect the GUS reporter gene expression, histochemical GUS staining and spectrophotometric assays were applied in each deletion variant. Finally the promoter sequence was analyzed by the PLACE (a database for PLAntCisacting Elements) program for identifying cis-elements. The results of the study showed significant difference in mock treated and induced expression in transgenic plants transformed with VvNAC36 promoter segments of different lengths, fused to GUS reporter gene. In basal expression level, the deletion variants 1178 bp and 257 bp differed significantly. Powdery mildew infection significantly increased the expression in all promoter variants, except the two shortest fragments. Based on the promoter motif analysis, it can be concluded, that the GT1-box (GAAAAA) supposed to have crucial role in regulating of VvNAC36 transcription factor gene during powdery mildew infection.
