Abstract
Cold stress is a key climatic factor that limits grape productivity and quality. Although β-amylase (BAM) is known to play an important role as a mediator of starch degradation under conditions of cold stress, the mechanism by which BAM regulates cold tolerance in grape remains unclear. Here, we identified VaBAM1 from Vitis amurensis and characterized its interactive regulating mechanism under cold stress in Arabidopsis thaliana and grape. VaBAM1-overexpressing A. thaliana plants (OEs) exhibited high freezing tolerance. Soluble sugar content and amylase activity were increased in OEs and VaBAM1-overexpressing grape calli (VaBAM1-OEs) under cold stress; however, they were decreased in grape calli in which VaBAM1 was edited using CRISPR/Cas9. The results of yeast two-hybrid, bimolecular fluorescence complementation, and pull-down experiments showed that serine/arginine-rich splicing factor 1 (VaSR1) interacted with VaBAM1. Furthermore, the expression of VaSR1 was opposite that of VaBAM1 in phloem tissue of Vitis amurensis during winter dormancy. In VaSR1-overexpressing grape calli (VaSR1-OEs), BAM activity and the expression levels of C-repeat binding transcription factor and cold response genes were all significantly lower than that in untransformed calli subjected to cold stress. Moreover, VvBAM1 was downregulated in VaSR1-OEs under cold stress. Overall, we identified that VaSR1 interacts with VaBAM1, negatively regulating BAM activity and resulting in decreased plant cold tolerance.

Advances in Biological Control and Resistance Genes of Brassicaceae Clubroot Disease-The Study Case of China. Int J Mol Sci 2023; 24:ijms24010785. [PMID: 36614228 PMCID: PMC9821010 DOI: 10.3390/ijms24010785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 12/20/2022] [Accepted: 12/21/2022] [Indexed: 01/03/2023] Open
Abstract
Clubroot disease is a soil-borne disease caused by Plasmodiophora brassicae. It occurs in cruciferous crops exclusively, and causes serious damage to the economic value of cruciferous crops worldwide. Although different measures have been taken to prevent the spread of clubroot disease, the most fundamental and effective way is to explore and use disease-resistance genes to breed resistant varieties. However, the resistance level of plant hosts is influenced both by environment and pathogen race. In this work, we described clubroot disease in terms of discovery and current distribution, life cycle, and race identification systems; in particular, we summarized recent progress on clubroot control methods and breeding practices for resistant cultivars. With the knowledge of these identified resistance loci and R genes, we discussed feasible strategies for disease-resistance breeding in the future.

Abstract
Protein S-acylation, also known as palmitoylation, is an important lipid post-translational modification of proteins in eukaryotes. S-acylation plays critical roles in a variety of protein functions involved in plant development and responses to abiotic and biotic stresses. The status of S-acylation on proteins is dynamic and reversible, which is catalyzed by protein S-acyltransferases (PATs) and reversed by acyl protein thioesterases. The cycle of S-acylation and de-S-acylation provides a molecular mechanism for membrane-associated proteins to undergo cycling and trafficking between different cell compartments and thus works as a switch to initiate or terminate particular signaling transductions on the membrane surface. In plants, thousands of proteins have been identified to be S-acylated through proteomics. Many S-acylated proteins and quite a few PAT-substrate pairs have been functionally characterized. A recently characterized acyl protein thioesterases family, ABAPT family proteins in Arabidopsis, has provided new insights into the de-S-acylation process. However, our understanding of the regulatory mechanisms controlling the S-acylation and de-S-acylation process is surprisingly incomplete. In this review, we discuss how protein S-acylation level is regulated with the focus on catalyzing enzymes in plants. We also propose the challenges and potential developments for the understanding of the regulatory mechanisms controlling protein S-acylation in plants.

Int J Mol Sci 2022; 23:ijms23136971. [PMID: 35805971 PMCID: PMC9266415 DOI: 10.3390/ijms23136971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 06/20/2022] [Accepted: 06/20/2022] [Indexed: 02/01/2023] Open
Abstract
The citrus industry has been threatened by Huanglongbing (HLB) for over a century. Here, an HLB-induced Arabidopsis RPM1-interacting protein 4 (RIN4) homologous gene was cloned from Citrus clementina, and its characteristics and function were analyzed to determine its role during citrus–Candidatus Liberibacter asiaticus (CLas) interactions. Quantitative real-time PCR showed that RIN4 was expressed in roots, stems, leaves and flowers, with the greatest expression level in leaves. Its expression was suppressed by gibberellic acid, indole-3-acetic acid, salicylic acid and jasmonic acid treatments, but was induced by abscisic acid and salt treatments, as well as wounding. The transient expression of a RIN4-GFP showed that RIN4 was localized in the cell membrane. RIN4-overexpressing transgenic C. maxima cv. ‘Shatianyou’ plants were obtained, and some transgenic plants showed greater sensitivity to CLas infection and earlier HLB symptoms appearance than non-transgenic controls. Results obtained in this study indicated that the upregulated expression of RIN4 in HLB diseased citrus may aid CLas infection.
