Abstract
Frequent flooding events induced by extreme weather significantly threaten plant growth and productivity. Salix matsudana, a willow species, demonstrates exceptional tolerance to hypoxia and submergence stress, providing an ideal model for exploring underlying molecular mechanisms. This study highlights the roles of two transcriptional factors and their interplay in enhancing hypoxia and submergence stress resilience in Salix matsudana. SmTTF30, a GT-1 trihelix transcription factor, is specifically induced under root hypoxia, with its promoter enriched in hypoxia-responsive elements. Functional analyses reveal that overexpression of SmTTF30 in Arabidopsis thaliana improves submergence tolerance, whereas its downregulation in Salix matsudana results in heightened submergence stress sensitivity. SmDREB A1-10, identified through yeast one-hybrid screening and dual-luciferase assays as an upstream regulator of SmTTF30, directly interacts with its promoter. Overexpression of SmDREB A1-10 in Arabidopsis thaliana also enhances submergence tolerance, similar to SmTTF30. Virus-induced gene silencing (VIGS) experiments confirm that silencing SmDREB A1-10 diminishes SmTTF30 expression and hypoxia-responsive gene activation, exacerbating submergence stress effects. These findings unveil a regulatory cascade involving SmDREB A1-10 and SmTTF30 in submergence stress responses, providing insights into transcriptional networks governing submergence tolerance in trees.

Enhanced multistress tolerance of Saccharomyces cerevisiae with the sugar transporter-like protein Stl1 F427L mutation in the presence of glycerol. Microbiol Spectr 2025; 13:e0008924. [PMID: 39679667 PMCID: PMC11792538 DOI: 10.1128/spectrum.00089-24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 10/05/2024] [Indexed: 12/17/2024] Open
Abstract
During microbial industrial production, microorganisms often face diverse stressors, including organic solvents, high salinity, and high sugar levels. Enhancing microorganism tolerance to such stresses is crucial for producing high-value-added products. Previous studies on the mechanisms of 2-phenylethanol (2-PE) tolerance in Saccharomyces cerevisiae revealed a potential connection between the sugar transporter-like protein (Stl1) mutation (F427L) and increased tolerance to high sugar and salt stress, suggesting a broader role in multistress tolerance. Herein, we showed that the Stl1F427L mutant strain (STL) exhibits significantly improved multistress tolerance in the presence of glycerol. Molecular dynamics simulations indicated that Stl1F427L may enhance glycerol molecular binding, resulting in a significant increase in the intracellular glycerol content of the mutant strain STL. Additionally, under multistress conditions, pyruvate and ergosterol levels and catalase (CAT) and superoxide dismutase (SOD) activities were significantly increased in the mutant strain STL compared with the control strain 5D. This resulted in a notable increase in cell membrane toughness and a decrease in intracellular reactive oxygen species levels. These findings highlight the mechanism by which Stl1F427L enhances S. cerevisiae tolerance to multistress. Importantly, they provide novel insights into and methodologies for improving the resilience of industrial microorganisms. IMPORTANCE Stl1F427L exhibits improved strain tolerance to multistress when adding glycerol, may enhance glycerol molecular binding, and can make a significant increase in intracellular glycerol content. It can reduce reactive oxygen species levels and increase ergosterol content. This paper provides novel insights and methods to get robust industrial microorganisms.

Populus euphratica R2R3-MYB transcription factor RAX2 binds ANN1 promoter to increase cadmium enrichment in Arabidopsis. PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2024; 344:112082. [PMID: 38583807 DOI: 10.1016/j.plantsci.2024.112082] [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: 01/20/2024] [Revised: 03/21/2024] [Accepted: 04/02/2024] [Indexed: 04/09/2024]
Abstract
The expression of R2R3-MYB transcription factor PeRAX2 increased transiently upon CdCl2 exposure (100 μM, 48 h) in leaves and roots of Populus euphratica. We observed that overexpression of PeRAX2 increased Cd2+ concentration in Arabidopsis root cells and Cd2+ amount in whole plant, which was due to the increased Cd2+ influx into root tips. However, the Cd2+ influx facilitated by PeRAX2 overexpression was substantially reduced by LaCl3 (an inhibitor of Ca2+-channels), suggesting that PeRAX2 could promote the Cd2+ entering through PM Ca2+-permeable channels (CaPCs) in the roots. It is noting that the expression of annexin1 (AtANN1), which mediates the influx of divalent cations through the PM calcium channels, was upregulated by Cd2+ in PeRAX2-transgenic Arabidopsis. Bioinformatic analysis revealed that the AtANN1 promoter (AtANN1-pro) contains four cis-elements for MYB binding. The PeRAX2 interaction with AtANN1-pro was validated by LUC reporter assay, EMSA, and Y1H assay. Our data showed that PeRAX2 binds to the AtANN1 promoter region to regulate gene transcription and that AtANN1 mediates the Cd2+ entry through CaPCs in the PM, leading to a Cd2+ enrichment in transgenic plants. The PeRAX2-stimulated Cd2+ enrichment consequently resulted in high H2O2 production in root cells of transgenic plants. The expression of AtSOD and AtPOD and activities of CAT, SOD, POD increased in the transgenic lines under Cd2+ stress. However, the Cd2+-upregulated expression and activity of antioxidative enzymes were less pronounced in the PeRAX2-overexpressed lines, compared to the wildtype and vector controls. As a result, root length and plant growth were more suppressed by Cd2+ in the transgenic lines. Our data suggest that transcriptional regulation of AtANN1 by PeRAX2 can be utilized to improve Cd2+ enrichment and phytoremediation, although the enriched Cd2+ affected antioxidant defense system and plant growth in the model species.

Abstract
The toxic metal cadmium (Cd) poses a serious threat to plant growth and human health. Populus euphratica calcium-dependent protein kinase 21 (CPK21) has previously been shown to attenuate Cd toxicity by reducing Cd accumulation, enhancing antioxidant defense and improving water balance in transgenic Arabidopsis. Here, we confirmed a protein-protein interaction between PeCPK21 and Arabidopsis nuclear transcription factor YC3 (AtNF-YC3) by yeast two-hybrid and bimolecular fluorescence complementation assays. AtNF-YC3 was induced by Cd and strongly expressed in PeCPK21-overexpressed plants. Overexpression of AtNF-YC3 in Arabidopsis reduced the Cd inhibition of root length, fresh weight and membrane stability under Cd stress conditions (100 µM, 7 d), suggesting that AtNF-YC3 appears to contribute to the improvement of Cd stress tolerance. AtNF-YC3 improved Cd tolerance by limiting Cd uptake and accumulation, activating antioxidant enzymes and reducing hydrogen peroxide (H2O2) production under Cd stress. We conclude that PeCPK21 interacts with AtNF-YC3 to limit Cd accumulation and enhance the reactive oxygen species (ROS) scavenging system and thereby positively regulate plant adaptation to Cd environments. This study highlights the interaction between PeCPK21 and AtNF-YC3 under Cd stress conditions, which can be utilized to improve Cd tolerance in higher plants.

Abstract
Abiotic stresses including cold, drought, salt, and iron deficiency severely impair plant development, crop productivity, and geographic distribution. Several bodies of research have shed light on the pleiotropic functions of BASIC HELIX-LOOP-HELIX (bHLH) proteins in plant responses to these abiotic stresses. In this review, we mention the regulatory roles of bHLH TFs in response to stresses such as cold, drought, salt resistance, and iron deficiency, as well as in enhancing grain yield in plants, especially crops. The bHLH proteins bind to E/G-box motifs in the target promoter and interact with various other factors to form a complex regulatory network. Through this network, they cooperatively activate or repress the transcription of downstream genes, thereby regulating various stress responses. Finally, we present some perspectives for future research focusing on the molecular mechanisms that integrate and coordinate these abiotic stresses. Understanding these molecular mechanisms is crucial for the development of stress-tolerant crops.

Populus euphratica GRP2 Interacts with Target mRNAs to Negatively Regulate Salt Tolerance by Interfering with Photosynthesis, Na +, and ROS Homeostasis. Int J Mol Sci 2024; 25:2046.

Abstract
The transcription of glycine-rich RNA-binding protein 2 (PeGRP2) transiently increased in the roots and shoots of Populus euphratica (a salt-resistant poplar) upon initial salt exposure and tended to decrease after long-term NaCl stress (100 mM, 12 days). PeGRP2 overexpression in the hybrid Populus tremula × P. alba '717-1B4' (P. × canescens) increased its salt sensitivity, which was reflected in the plant's growth and photosynthesis. PeGRP2 contains a conserved RNA recognition motif domain at the N-terminus, and RNA affinity purification (RAP) sequencing was developed to enrich the target mRNAs that physically interacted with PeGRP2 in P. × canescens. RAP sequencing combined with RT-qPCR revealed that NaCl decreased the transcripts of PeGRP2-interacting mRNAs encoding photosynthetic proteins, antioxidative enzymes, ATPases, and Na+/H+ antiporters in this transgenic poplar. Specifically, PeGRP2 negatively affected the stability of the target mRNAs encoding the photosynthetic proteins PETC and RBCMT; antioxidant enzymes SOD[Mn], CDSP32, and CYB1-2; ATPases AHA11, ACA8, and ACA9; and the Na+/H+ antiporter NHA1. This resulted in (i) a greater reduction in Fv/Fm, YII, ETR, and Pn; (ii) less pronounced activation of antioxidative enzymes; and (iii) a reduced ability to maintain Na+ homeostasis in the transgenic poplars during long-term salt stress, leading to their lowered ability to tolerate salinity stress.

Li J, Yang Y. How do plants maintain pH and ion homeostasis under saline-alkali stress? FRONTIERS IN PLANT SCIENCE 2023; 14:1217193. [PMID: 37915515 PMCID: PMC10616311 DOI: 10.3389/fpls.2023.1217193] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 09/25/2023] [Indexed: 11/03/2023]
Abstract
Salt and alkaline stresses often occur together, severely threatening plant growth and crop yields. Salt stress induces osmotic stress, ionic stress, and secondary stresses, such as oxidative stress. Plants under saline-alkali stress must develop suitable mechanisms for adapting to the combined stress. Sustained plant growth requires maintenance of ion and pH homeostasis. In this review, we focus on the mechanisms of ion and pH homeostasis in plant cells under saline-alkali stress, including regulation of ion sensing, ion uptake, ion exclusion, ion sequestration, and ion redistribution among organs by long-distance transport. We also discuss outstanding questions in this field.
