Arch Microbiol 2024; 206:241. [PMID: 38698267 DOI: 10.1007/s00203-024-03925-5] [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: 12/02/2023] [Revised: 02/25/2024] [Accepted: 03/04/2024] [Indexed: 05/05/2024]
Abstract
The epidemic of stripe rust, caused by the pathogen Puccinia striiformis f. sp. tritici (Pst), would reduce wheat (Triticum aestivum) yields seriously. Traditional experimental methods are difficult to discover the interaction between wheat and Pst. Multi-omics data analysis provides a new idea for efficiently mining the interactions between host and pathogen. We used 140 wheat-Pst RNA-Seq data to screen for differentially expressed genes (DEGs) between low susceptibility and high susceptibility samples, and carried out Gene Ontology (GO) enrichment analysis. Based on this, we constructed a gene co-expression network, identified the core genes and interacted gene pairs from the conservative modules. Finally, we checked the distribution of Nucleotide-binding and leucine-rich repeat (NLR) genes in the co-expression network and drew the wheat NLR gene co-expression network. In order to provide accessible information for related researchers, we built a web-based visualization platform to display the data. Based on the analysis, we found that resistance-related genes such as TaPR1, TaWRKY18 and HSP70 were highly expressed in the network. They were likely to be involved in the biological processes of Pst infecting wheat. This study can assist scholars in conducting studies on the pathogenesis and help to advance the investigation of wheat-Pst interaction patterns.

Qin H, Cui X, Shu X, Zhang J. The transcription factor VaNAC72-regulated expression of the VaCP17 gene from Chinese wild Vitis amurensis enhances cold tolerance in transgenic grape (V. vinifera). PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2023; 200:107768. [PMID: 37247556 DOI: 10.1016/j.plaphy.2023.107768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 05/02/2023] [Accepted: 05/15/2023] [Indexed: 05/31/2023]
Abstract
Papain-like cysteine proteases (PLCP) play diverse roles in plant biology. In our previous studies, a VaCP17 gene from the cold-tolerant Vitis amurensis accession 'Shuangyou' was isolated and its role in cold tolerance was preliminarily verified in Arabidopsis. Here, we confirmed the function of VaCP17 in cold tolerance by stably overexpressing VaCP17 in the cold-sensitive Vitis vinifera cultivar 'Thompson Seedless' and transiently silencing VaCP17 in 'Shuangyou' leaves. The results showed that overexpression of VaCP17 improved the cold tolerance in 'Thompson Seedless' as manifested by reduced electrolyte leakage and malondialdehyde accumulation, chlorophyll homeostasis, increased antioxidant enzymes (superoxide dismutase, peroxidase, and catalase) activitiy, and rapid up-regulation of stress-related genes (VvKIN2, VvRD29B, and VvNCED1) compared with wild-type line. Conversely, RNA interfere-mediated knockdown of VaCP17 in 'Shuangyou' leaves resulted in opposite physiological and biochemical responses and exacerbated leaves wilting compared with control. Subsequently, by yeast one-hybrid, dual-luciferase assays, and transient overexpression of VaNAC72 in 'Shuangyou' leaves, a VaCP17-interacting protein VaNAC72 was confirmed to promote the expression of VaCP17 under cold stress, which depends on abscisic acid, methyl jasmonate, and salicylic acid signaling. By yeast two-hybrids, bimolecular fluorescence complementation and luciferase complementation assays, it was found that VaNAC72 could form homodimers or heterodimers with VaCBF2. Furthermore, co-expression analysis confirmed that VaNAC72 works synergistically with VaCBF2 or VaCP17 to up-regulate the expression of VaCP17. In conclusion, the study revealed that the VaNAC72-VaCP17 module positively regulated cold tolerance in grapevine, and this knowledge is useful for further revealing the cold-tolerance mechanism of V. amurensis and grape molecular breeding.

Reveals Hypersensitive Responses to Plasmopara viticola. Front Microbiol 2022; 13:846504. [PMID: 35572700 PMCID: PMC9097084 DOI: 10.3389/fmicb.2022.846504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Accepted: 03/24/2022] [Indexed: 11/13/2022] Open
Abstract
Grapevine downy mildew is the most serious disease of grapevine cultivars that affects the rate of resistance/susceptibility to Plasmopara viticola. In this study, we used the susceptible cultivar "Zitian Seedless" and the resistant cultivar "Kober 5BB" as materials to determine the transcriptome differences and phenotypes of the leaves after inoculation with downy mildew. The differences in microstructures and molecular levels were compared and analyzed. Fluorescence staining and microscopic observations confirmed that hypersensitive cell death occurred around the stomata in "Kober 5BB" infected by downy mildew zoospores. Meanwhile, transcriptomic profiling indicated that there were 11,713 and 6,997 gene expression differences between the resistant and susceptible cultivars at 72 h after inoculation when compared to control (0 h), respectively. The differentially expressed genes of the two cultivars are significantly enriched in different pathways, including response to plant-pathogen interaction, mitogen-activated protein kinase (MAPK) signaling pathway, plant hormone signal transduction, phenylpropanoid, and flavonoid biosynthesis. Furthermore, the results of functional enrichment analysis showed that H2O2 metabolism, cell death, reactive oxygen response, and carbohydrate metabolism are also involved in the defense response of "Kober 5BB," wherein a total of 322 key genes have been identified. The protein interaction network showed that metacaspases (MCAs), vacuolar processing enzymes (VPEs), and Papain-like cysteine proteases (PLCPs) play an important role in the execution of hypersensitive responses (HR). In conclusion, we demonstrated that HR cell death is the key strategy in the process of grape defense against downy mildew, which may be mediated or activated by Caspase-like proteases.
