Genome-wide investigation and analysis of NAC transcription factor family in Populus tomentosa and expression analysis under salt stress. PLANT BIOLOGY (STUTTGART, GERMANY) 2024; 26:764-776. [PMID: 38859551 DOI: 10.1111/plb.13657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 04/20/2024] [Indexed: 06/12/2024]
Abstract
The NAC transcription factor family is one of the largest families of TFs in plants, and members of NAC gene family play important roles in plant growth and stress response. Recent release of the haplotype-resolved genome assembly of P. tomentosa provide a platform for NAC protein genome-wide analysis. A total of 270 NAC genes were identified and a comprehensive overview of the PtoNAC gene family is presented, including gene promoter, structure and conserved motif analyses, chromosome localization and collinearity analysis, protein phylogeny, expression pattern, and interaction analysis. The results indicate that protein length, molecular weight, and theoretical isoelectric points of the NAC TF family vary, while gene structure and motif are relatively conserved. Chromosome mapping analysis showed that the P. tomentosa NAC genes are unevenly distributed on 19 chromosomes. The interchromosomal evolutionary results indicate 12 pairs of tandem and 280 segmental duplications. Segmental duplication is possibly related to amplification of P. tomentosa NAC gene family. Expression patterns of 35 PtoNAC genes from P. tomentosa subgroup were analysed under high salinity, and seven NAC genes were induced by this treatment. Promoter and protein interaction network analyses showed that PtoNAC genes are closely associated with growth, development, and abiotic and biotic stress, especially salt stress. These results provide a meaningful reference for follow-up studies of the functional characteristics of NAC genes in the mechanism of stress response and their potential roles in development of P. tomentosa.

Abstract
NAC transcription factors play a significant role in plant stress responses. In this study, an NAC transcription factor, with a CDS of 792 bp encoding 263 amino acids, was cloned from Fagopyrum tataricum (L.) Gaertn. (F. tataricum), a minor cereal crop, which is rich in flavonoids and highly stress resistant. The transcription factor was named FtNAC10 (NCBI accession number: MK614506.1) and characterized as a member of the NAP subgroup of NAC transcriptions factors. The gene exhibited a highly conserved N-terminal, encoding about 150 amino acids, and a highly specific C-terminal. The resulting protein was revealed to be hydrophilic, with strong transcriptional activation activity. FtNAC10 expression occurred in various F. tataricum tissues, most noticeably in the root, and was regulated differently under various stress treatments. The over-expression of FtNAC10 in transgenic Arabidopsis thaliana (A. thaliana) seeds inhibited germination, and the presence of FtNAC10 enhanced root elongation under saline and drought stress. According to phylogenetic analysis and previous reports, our experiments indicate that FtNAC10 may regulate the stress response or development of F. tataricum through ABA-signaling pathway, although the mechanism is not yet known. This study provides a reference for further analysis of the regulatory function of FtNAC10 and the mechanism that underlies stress responses in Tartary buckwheat.

Abstract
To explore the role of NAC transcription factors in mung bean (Vigna ratiata), we here comprehensively analyzed VrNAC13 structure and expression patterns in the mung bean cultivar "Yulin No.1". The nucleotide sequence of VrNAC13 (GenBank accession number xp014518431.1) was determined by cloning and sequencing the gene. A predicted transcriptional activation domain in VrNAC13 was validated with a yeast one-hybrid assay. The composition and functional characteristics of VrNAC13 were analyzed using basic bioinformatics techniques, and the expression characteristics of VrNAC13 were analyzed via quantitative reverse transcription-PCR. The results showed that VrNAC13 was 1,068 bp in length and encoded a product of 355 amino acids. VrNAC13 was predicted to contain a NAM domain and to belong to the NAC transcription factor family. The protein was hydrophilic and contained several threonine phosphorylation sites. Phylogenetic analysis showed that VrNAC13 was highly similar in sequence to two Arabidopsis thaliana NAC proteins; we hypothesize that VrNAC13 may perform functions in mung bean similar to those of the two closely related proteins in Arabidopsis. Promoter analysis of VrNAC13 revealed cis-acting elements predicted to respond to abscisic acid (ABA), gibberellin, auxin, light, drought, low temperature, and other stressors. VrNAC13 was most highly expressed in the leaves and expressed at very low levels in the stem and root. It was experimentally determined to be induced by drought and ABA. Based on these results, VrNAC13 appears to regulate stress resistance in mung bean.

JOURNAL OF HAZARDOUS MATERIALS 2023; 452:131318. [PMID: 37011447 DOI: 10.1016/j.jhazmat.2023.131318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 03/13/2023] [Accepted: 03/27/2023] [Indexed: 05/03/2023]
Abstract
To clarify how phosphorus (P) influences arbuscular mycorrhizal fungi (AMF) interactions with host plants, we measured the effects of variation in environmental P levels and AMF colonization on photosynthesis, element absorption, ultrastructure, antioxidant capacity, and transcription mechanisms in Phragmites australis (P. australis) under cadmium (Cd) stress. AMF maintained photosynthetic stability, element balance, subcellular integrity and enhanced antioxidant capacity by upregulating antioxidant gene expression. Specifically, AMF overcame Cd-induced stomatal limitation, and mycorrhizal dependence peaked in the high Cd-moderate P treatment (156.08%). Antioxidants and compatible solutes responded to P-level changes: the primary driving forces of removing reactive oxygen species (ROS) and maintaining osmotic balance were superoxide dismutase, catalase, and sugars at limited P levels and total polyphenol, flavonoid, peroxidase, and proline at abundant P levels, we refer to this phenomenon as "functional link." AMF and phosphorus enhanced Cd tolerance in P. australis, but the regulation of AMF was P-dependent. Phosphorus prevented increases in total glutathione content and AMF-induced GSH/GSSG ratio (reduced to oxidized glutathione ratio) by inhibiting the expression of assimilatory sulfate reduction and glutathione reductase genes. The AMF-induced flavonoid synthesis pathway was regulated by P, and AMF activated Cd-tolerance mechanisms by inducing P-dependent signaling.

Abstract
Plant cell wall biosynthesis is a complex and tightly regulated process. The composition and the structure of the cell wall should have a certain level of plasticity to ensure dynamic changes upon encountering environmental stresses or to fulfil the demand of the rapidly growing cells. The status of the cell wall is constantly monitored to facilitate optimal growth through the activation of appropriate stress response mechanisms. Salt stress can severely damage plant cell walls and disrupt the normal growth and development of plants, greatly reducing productivity and yield. Plants respond to salt stress and cope with the resulting damage by altering the synthesis and deposition of the main cell wall components to prevent water loss and decrease the transport of surplus ions into the plant. Such cell wall modifications affect biosynthesis and deposition of the main cell wall components: cellulose, pectins, hemicelluloses, lignin, and suberin. In this review, we highlight the roles of cell wall components in salt stress tolerance and the regulatory mechanisms underlying their maintenance under salt stress conditions.

Abstract
TIFY proteins play crucial roles in plant abiotic and biotic stress responses. Our transcriptome data revealed several TIFY family genes with significantly upregulated expression under drought, salt, and ABA treatments. However, the functions of the GmTIFY family genes are still unknown in abiotic stresses. We identified 38 GmTIFY genes and found that TIFY10 homologous genes have the most duplication events, higher selection pressure, and more obvious response to abiotic stresses compared with other homologous genes. Expression pattern analysis showed that GmTIFY10e and GmTIFY10g genes were significantly induced by salt stress. Under salt stress, GmTIFY10e and GmTIFY10g transgenic Arabidopsis plants showed higher root lengths and fresh weights and had significantly better growth than the wild type (WT). In addition, overexpression of GmTIFY10e and GmTIFY10g genes in soybean improved salt tolerance by increasing the PRO, POD, and CAT contents and decreasing the MDA content; on the contrary, RNA interference plants showed sensitivity to salt stress. Overexpression of GmTIFY10e and GmTIFY10g in Arabidopsis and soybean could improve the salt tolerance of plants, while the RNAi of GmTIFY10e and GmTIFY10g significantly increased sensitivity to salt stress in soybean. Further analysis demonstrated that GmTIFY10e and GmTIFY10g genes changed the expression levels of genes related to the ABA signal pathway, including GmSnRK2, GmPP2C, GmMYC2, GmCAT1, and GmPOD. This study provides a basis for comprehensive analysis of the role of soybean TIFY genes in stress response in the future.

Abstract
The nuclear factor Y (NF-Y) is an important transcription factor family that regulates plant developmental processes and abiotic stress responses. Currently, genome-wide studies of the NF-Y family are limited in Fagopyrum tataricum, an important economic crop. Based on the released genome assembly, we predicted a total of 38 NF-Y encoding genes (FtNF-Ys), including 12 FtNF-YAs, 18 FtNF-YBs, and eight FtNF-YCs subunits, in F. tataricum. Phylogenetic tree and sequence alignments showed that FtNF-Ys were conserved between F. tataricum and other species. Tissue expressions and network analyses suggested that FtNF-Ys might be involved in regulating developmental processes in different tissues. Several FtNF-YAs and FtNF-Ybs were also potentially involved in light response. In addition, FtNF-YC-like1 and FtNF-YC-like2 partially rescued the late flowering phenotype in nf-yc1 nf-yc3 nf-yc4 nf-yc9 (ycQ) mutant in Arabidopsis thaliana, supporting a conserved role of FtNF-Ys in regulating developmental processes. Together, the genomic information provides a comprehensive understanding of the NF-Y transcription factors in F. tataricum, which will be useful for further investigation of their functions in F. tataricum.
