“…In transgenic rice, overexpression of EcNAC67 upon drought stress displayed higher seedling vigor, lower spikelet sterility and enhanced tolerance to drought stress [75]. Overexpression of TaNAC47 and ONAC066 enhanced drought tolerance in wheat [76] and rice [77], respectively. Moreover, GhNAC2 [78] showed the potential to enhance root growth and tolerance against limited water supply in transgenic cotton and Arabidopsis.…”

Increasing vulnerability of crops to a wide range of abiotic and biotic stresses can have a marked influence on the growth and yield of major crops, especially sugarcane (Saccharum spp.). In response to various stresses, plants have evolved a variety of complex defense systems of signal perception and transduction networks. Transcription factors (TFs) that are activated by different pathways of signal transduction and can directly or indirectly combine with cis-acting elements to modulate the transcription efficiency of target genes, which play key regulators for crop genetic improvement. Over the past decade, significant progresses have been made in deciphering the role of plant TFs as key regulators of environmental responses in particular important cereal crops; however, a limited amount of studies have focused on sugarcane. This review summarizes the potential functions of major TF families, such as WRKY, NAC, MYB and AP2/ERF, in regulating gene expression in the response of plants to abiotic and biotic stresses, which provides important clues for the engineering of stress-tolerant cultivars in sugarcane.

“…MdNAC1 was found to be associated with plant height, and overexpression of the gene resulted in a dwarf phenotype in transgenic apple plants. Furthermore, NAC TFs are involved in responding to multiple stresses, such as pathogen immunity [ 24 ], salt [ 25 ], drought [ 26 ], cold [ 27 ] and heat [ 28 ]. The membrane-bound protein NTL8 induced by salt stress can regulate Arabidopsis seed germination through the gibberellin acid (GA) pathway.…”

Plant-specific NAC (NAM, ATAF, CUC) transcription factor (TF) family plays important roles in biological processes such as plant growth and response to stress. Nevertheless, no information is known about NAC TFs in Cleistogenes songorica, a prominent xerophyte desert grass in northwestern China. In this study, 162 NAC genes were found from the Cleistogenes songorica genome, among which 156 C. songoricaNAC (CsNAC) genes (96.3%) were mapped onto 20 chromosomes. The phylogenetic tree constructed by CsNAC and rice NAC TFs can be separated into 14 subfamilies. Syntenic and Ka/Ks analyses showed that CsNACs were primarily expanded by genomewide replication events, and purifying selection was the primary force driving the evolution of CsNAC family genes. The CsNAC gene expression profiles showed that 36 CsNAC genes showed differential expression between cleistogamous (CL) and chasmogamous (CH) flowers. One hundred and two CsNAC genes showed differential expression under heat, cold, drought, salt and ABA treatment. Twenty-three CsNAC genes were commonly differentially expressed both under stress responses and during dimorphic floret development. Gene Ontology (GO) annotation, coexpression network and qRT-PCR tests revealed that these CsNAC genes may simultaneously regulate dimorphic floret development and the response to stress. Our results may help to characterize the NAC transcription factors in C. songorica and provide new insights into the functional research and application of the NAC family in crop improvement, especially in dimorphic floret plants.

“…), NAC TF GmSIN1 participates in the process of plants response to salt stress by promoting the accumulation of ABA (abscisic acid)and reactive oxygen species (ROS); meanwhile, it could also activate the development of plant root [17]. In rice (Oryza sativa L.), the ONAC066 overexpression plants showed an increased drought tolerance compared with wild-type (WT), whereas the drought-tolerance ability of plants was significantly inhibited by RNA interference [18]. Furthermore, many studies have demonstrated that plants respond to abiotic stresses by altering the levels of endogenous hormones, such as ABA and GA (gibberellin acid) [19,20].…”

“…Despite the universal investigation of NAC TFs in model plants such as Arabidopsis and rice in response to abiotic stresses [18,23], little is known about the characterization and molecular mechanism of NAC TFs in blueberry tree when subjected to drought stress. In the present study, the chlorophyll a fluorescence parameters of leaf (ϕ Po , ϕ Eo , ϕ Ro , and PIabs) and several phytohormones were measured under drought stress.…”

Research Highlights: Phenotypic changes and expression profiles, phylogeny, conserved motifs, and expression correlations of NAC (NAM, ATAF1, ATAF2 and CUC2) transcription factors (TFs) in blueberry genome were detected under drought stress, and the expression patterns and functions of 12 NACs were analyzed. Background and Objectives: Blueberry is an important shrub species with a high level of flavonoids in fruit, which are implicated in a broad range of health benefits. However, the molecular mechanism of this shrub species in response to drought stress still remains elusive. NAC TFs widely participate in stress tolerance in many plant species. The characterization and expression profiles of NAC TFs were analyzed on the basis of genome data in blueberry when subjected to drought stress. Materials and Methods: Combined with the analysis of chlorophyll a fluorescence and endogenous phytohormones, the phenotypic changes of blueberry under drought stress were observed. The phylogenetic tree, conserved motifs, differently expressed genes, and expression correlation were determined by means of multiple bioinformatics analysis. The expression profiles of NACs in different organs were examined and compared through RNA-seq and qRT-PCR assay. Results: The chlorophyll a fluorescence parameters φPo, φEo, φRo, and PIabs of leaves were significantly inhibited under drought stress. ABA (abscisic acid) content noticeably increased over the duration of drought, whereas GA3 (gibberellic acid) and IAA (indole acetic acid) content decreased continuously. A total of 158 NACs were identified in blueberry genome and 62 NACs were differently expressed in leaf and root of blueberry under drought stress. Among them, 14 NACs were significantly correlated with the expression of other NAC genes. Conclusions: Our results revealed the phenotypic changes of this shrub under drought stress and linked them with NAC TFs, which are potentially involved in the process of response to drought stress.
