“…In rice, it was reported that SNAC3 play a positive role in heat resistance through regulating downstream ROS-associated genes expression [53]. In plants, NAC genes overexpression also generated cold tolerance by upregulating some thermotolerance-related genes, as well as inducing the increased activity of antioxidant enzymes [54]. In the present study, 16 genes related to NAC TFs were enriched in the three clusters, and six of these genes were expressed in cluster 7.…”

Background: Gossypium barbadense L. is the most important renewable source of textile fiber. Cotton fiber cell initiation and elongation are often affected by various environmental stimulus, such as high temperature. However, little is known about the underlying mechanisms of temperature regulating the fuzz fiber initiation.Results: In the present study, phenotypic observation revealed that high temperature (HT) accelerated the fiber development, improved fiber quality and induced fuzz fiber initiation. It has been proved that the fuzz fiber initiation was inhibited by low temperature (LT), and 4 days post-anthesis (DPA) was the key stage for fuzz fiber initiation. Based on comparative transcriptome analysis, a total of 43,826 differentially expressed genes (DEGs) were identified, of which 9,667 were involved in both fiber development and temperature response with 901 transcription factor genes and 189 genes related to plant hormone signal transduction. Further analysis of gene expression patterns revealed that 240 genes were involved in fuzz fiber initiation. Functional annotation revealed that the candidate genes related to fuzz initiation were significantly involved in asparagine biosynthetic process, cell wall biosynthesis and stress response. Furthermore, the expression trends of sixteen selected genes from the RNA-seq data were almost consistent with the results of qRT-PCR results.Conclusions: Our study revealed several potential candidate genes and pathways that related to fuzz fiber initiation induced by high-temperature and provided a new view of temperature-induced tissue and organ development in Gossypium barbadense.

Agave, monocotyledonous succulent plants, is endemic to arid regions of North America, exhibiting exceptional tolerance to their xeric environments. They employ various strategies to overcome environmental constraints, such as crassulacean acid metabolism, wax depositions, and protective leaf morphology. Genomic resources of Agave species have received little attention irrespective of their cultural, economic and ecological importance, which so far prevented the understanding of the molecular bases underlying their adaptations to the arid environment. In this study, we aimed to elucidate molecular mechanism(s) using transcriptome sequencing of A. sisalana. A de novo approach was applied to assemble paired-end reads. The expression study unveiled 3,095 differentially expressed unigenes between well-irrigated and drought-stressed leaf samples. Gene ontology and KEGG analysis specified a significant number of abiotic stress responsive genes and pathways involved in processes like hormonal responses, antioxidant activity, response to stress stimuli, wax biosynthesis, and ROS metabolism. We also identified transcripts belonging to several families harboring important drought-responsive genes. Our study provides the first insight into the genomic structure of A. sisalana underlying adaptations to drought stress, thus providing diverse genetic resources for drought tolerance breeding research.

“…Moreover, significant progress has demonstrated that many NAC TFs are also involved in the response to various abiotic stresses, such as drought, salt, and cold. There is plenty of evidence, even in field trials, that transgenic plants overexpressing NAC genes have improved stress resistance, suggesting that they are promising candidate genes for genetic engineering of crops aimed at enhancing productivity under environmental stresses (Tran et al, 2010; Marques et al, 2017). Bioinformatics data obtained by transcriptome sequencing predict that ~20 to 25% of NAC genes function in at least one type of abiotic stresses including drought, salt, and cold (Puranik et al, 2012).…”

NAC (NAM, ATAF, and CUC) transcription factors function as the nodes of regulatory networks in response to various biotic and abiotic stresses. Although they have been widely studied in many species, no knowledge concerning salt‐stress‐responsive NAC genes is available in sweetpotato (Ipomoea batatas L.). In the present study, 12 novel putative NAC genes, designated as IbNAC1L and IbNAC3 through IbNAC13, were isolated on the basis of the salt‐stress‐treated RNA sequencing data of two sweetpotato cultivars (‘XuShu 22’ and ‘XuShu 32’) with different levels of salt tolerance. Motif compositions showed that all the IbNAC proteins except IbNAC9 contain five conserved subdomains in the NAC domain region that characterizes the NAC gene family. Furthermore, systematic expression analysis and function evaluation of these IbNAC genes were conducted using quantitative real‐time polymerase chain reaction. The results showed that the expression of most IbNAC genes was exclusively induced by multiple abiotic stresses, including NaCl, dehydration, cold, and heat. Varying degrees of induction were also observed in the transcription levels of these IbNACs, except IbNAC10, when treated with various hormones, including abscisic acid, 1‐aminocyclopropane‐1‐carboxylate, gibberellic acid, and jasmonic acid. Cumulatively, the data of stress‐responsive IbNAC genes in the present study will provide valuable information for further exploring the crucial and diverse roles of IbNAC genes in sweetpotato stress tolerance.
