摘要

尽管在以前的文章中已经发现了病原相关 10(PR-10)蛋白,但它仍然相对被忽视,在许多植物物种中尚未得到全面表征。本研究采用了一种全面的数据挖掘方法,对全球重要的农作物--木薯中的 PR-10 蛋白进行了硅学表征。在这项研究中,重点研究了在硅学中鉴定出的 53 种木薯 PR-10 蛋白,根据它们之间的系统发育关系,这些蛋白可分为两大类:34 种主要乳胶蛋白(MLPs)和 13 种主要过敏原蛋白 Pru ar 1。与橡胶树的基因组共线性分析表明,这两种大戟科植物之间的 PR-10 基因可能存在进化关系,特别是在它们的 15 号染色体上。值得注意的是,在以前发表的各种木薯转录组数据集中,发现了 MLP423 和其他 MLP 蛋白对炭疽病菌、病毒和细菌性枯萎病等多种植物病原体的生物处理的响应。三个 MLP423 蛋白的配体预测和分子对接揭示了它们与细胞分裂素和脱落酸激素的潜在相互作用。本文讨论了它们的表达和预测的结合亲和力,强调了它们在木薯防御关键病害网络中的作用。

Genome-wide identification and data mining reveals major-latex protein (MLP) from the PR-10 protein family played defense-related roles against phytopathogenic challenges in cassava (Manihot esculenta Crantz).

Genome-wide identification and data mining reveals major-latex protein (MLP) from the PR-10 protein family played defense-related roles against phytopathogenic challenges in cassava (Manihot esculenta Crantz).

Despite being identified in previous articles, the pathogenesis-related 10 (PR-10) protein remains relatively overlooked and has yet to be fully characterized in numerous plant species. This research employs a comprehensive data mining approach to in silico characterize PR-10 proteins in cassava, a vital crop plant globally. In this study, the focus was on in silico identified 53 cassava PR-10 proteins, which can be categorized into two main subgroups: 34 major latex proteins (MLPs) and 13 major allergen proteins, Pru ar 1, based on their phylogenetic relationship. The genome collinearity analysis with the rubber tree showed a possible evolutionary relationship of the PR-10 gene between these two Euphorbiaceae species, specifically on their chromosome 15. Notably, MLP423 and other MLP proteins were identified in various previously published cassava transcriptome datasets in response to biotic treatments from diverse phytopathogens, including anthracnose fungus, viruses, and bacterial blight. Ligand prediction and molecular docking of three MLP423 proteins have revealed potential interaction with cytokinin and abscisic acid hormones. Their expressions and predicted binding affinities are discussed here, highlighting their role as contributors to cassava's defense network against key diseases.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
