Cui C, Wan H, Li Z, Ai N, Zhou B. Long noncoding RNA TRABA suppresses β-glucosidase-encoding BGLU24 to promote salt tolerance in cotton. PLANT PHYSIOLOGY 2024; 194:1120-1138. [PMID: 37801620 DOI: 10.1093/plphys/kiad530] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 08/23/2023] [Accepted: 09/04/2023] [Indexed: 10/08/2023]
Abstract
Salt stress severely damages the growth and yield of crops. Recently, long noncoding RNAs (lncRNAs) were demonstrated to regulate various biological processes and responses to environmental stresses. However, the regulatory mechanisms of lncRNAs in cotton (Gossypium hirsutum) response to salt stress are still poorly understood. Here, we observed that a lncRNA, trans acting of BGLU24 by lncRNA (TRABA), was highly expressed while GhBGLU24-A was weakly expressed in a salt-tolerant cotton accession (DM37) compared to a salt-sensitive accession (TM-1). Using TRABA as an effector and proGhBGLU24-A-driven GUS as a reporter, we showed that TRABA suppressed GhBGLU24-A promoter activity in double transgenic Arabidopsis (Arabidopsis thaliana), which explained why GhBGLU24-A was weakly expressed in the salt-tolerant accession compared to the salt-sensitive accession. GhBGLU24-A encodes an endoplasmic reticulum (ER)-localized β-glucosidase that responds to salt stress. Further investigation revealed that GhBGLU24-A interacted with RING-type E3 ubiquitin ligase (GhRUBL). Virus-induced gene silencing (VIGS) and transgenic Arabidopsis studies revealed that both GhBGLU24-A and GhRUBL diminish plant tolerance to salt stress and ER stress. Based on its substantial effect on ER-related degradation (ERAD)-associated gene expression, GhBGLU24-A mediates ER stress likely through the ERAD pathway. These findings provide insights into the regulatory role of the lncRNA TRABA in modulating salt and ER stresses in cotton and have potential implications for developing more resilient crops.

A homolog of AtCBFs, SmDREB A1-4, positively regulates salt stress tolerance in Arabidopsis thaliana and Salix matsudana. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2023; 202:107963. [PMID: 37595402 DOI: 10.1016/j.plaphy.2023.107963] [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: 06/20/2023] [Revised: 07/22/2023] [Accepted: 08/10/2023] [Indexed: 08/20/2023]
Abstract
CBFs (C-repeat binding factors) have multiple functions in abiotic stress adaption; functional research of these genes will provide precious gene resources for plant genetic improvement. In this study, a homolog of AtCBFs, SmDREB A1-4 was cloned and its role in salt tolerance was explored. SmDREB A1-4 is a member of DREB A1 subgroup with 10 members. SmDREB A1-4 localized in nuclei and cytoplasm and expressed ubiquitously in different tissue and organs. The expression level of SmDREB A1-4 could be induced by NaCl treatment and the TC-rich repeat and DREB motif on the SmDREB A1-4 gene promoter may mediate the NaCl-induced expression pattern. Overexpression of the SmDREB A1-4 gene in Arabidopsis enhanced the salt tolerance of transgenic Arabidopsis lines, while down-regulated the expression level in Salix plantlets by Virus induce gene silencing decreased the salt tolerance capacity in VIGS Salix plantlets. Experiments data from both sides confirmed that SmDREB A1-4 is a positive regulatory factor in salt stress tolerance. qRT-PCR and luciferase reporter assays revealed that SOS1 and DREB2A are downstream genes of SmDREB A1-4. Through upregulating the expression of SOS1 and DREB2A, SmDREB A1-4 enhanced plant tolerance to salinity by regulating ion homeostasis, reduction of Na+/K+ ratio, and improvement of proline biosynthesis. This research offers a potentially valuable gene resource for the stress-resistant varieties breeding of Salix matsudana in the future.

Peng Z, Rehman A, Li X, Jiang X, Tian C, Wang X, Li H, Wang Z, He S, Du X. Comprehensive Evaluation and Transcriptome Analysis Reveal the Salt Tolerance Mechanism in Semi-Wild Cotton ( Gossypium purpurascens). Int J Mol Sci 2023; 24:12853. [PMID: 37629034 PMCID: PMC10454576 DOI: 10.3390/ijms241612853] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/03/2023] [Accepted: 08/14/2023] [Indexed: 08/27/2023] Open
Abstract
Elevated salinity significantly threatens cotton growth, particularly during the germination and seedling stages. The utilization of primitive species of Gossypium hirsutum, specifically Gossypium purpurascens, has the potential to facilitate the restoration of genetic diversity that has been depleted due to selective breeding in modern cultivars. This investigation evaluated 45 G. purpurascens varieties and a salt-tolerant cotton variety based on 34 morphological, physiological, and biochemical indicators and comprehensive salt tolerance index values. This study effectively identified a total of 19 salt-tolerant and two salt-resistant varieties. Furthermore, transcriptome sequencing of a salt-tolerant genotype (Nayanmian-2; NY2) and a salt-sensitive genotype (Sanshagaopao-2; GP2) revealed 2776, 6680, 4660, and 4174 differentially expressed genes (DEGs) under 0.5, 3, 12, and 24 h of salt stress. Gene ontology enrichment analysis indicated that the DEGs exhibited significant enrichment in biological processes like metabolic (GO:0008152) and cellular (GO:0009987) processes. MAPK signaling, plant-pathogen interaction, starch and sucrose metabolism, plant hormone signaling, photosynthesis, and fatty acid metabolism were identified as key KEGG pathways involved in salinity stress. Among the DEGs, including NAC, MYB, WRKY, ERF, bHLH, and bZIP, transcription factors, receptor-like kinases, and carbohydrate-active enzymes were crucial in salinity tolerance. Weighted gene co-expression network analysis (WGCNA) unveiled associations of salt-tolerant genotypes with flavonoid metabolism, carbon metabolism, and MAPK signaling pathways. Identifying nine hub genes (MYB4, MYB105, MYB36, bZIP19, bZIP43, FRS2 SMARCAL1, BBX21, F-box) across various intervals offered insights into the transcriptional regulation mechanism of salt tolerance in G. purpurascens. This study lays the groundwork for understanding the important pathways and gene networks in response to salt stress, thereby providing a foundation for enhancing salt tolerance in upland cotton.
