{"title":"De novo assembly-based transcriptome analysis of resistant and susceptible potato varieties to Phytophthora infestans","authors":"Heba A. Mahfouze, O. E. El-Sayed","doi":"10.1007/s42161-024-01636-w","DOIUrl":"https://doi.org/10.1007/s42161-024-01636-w","url":null,"abstract":"<p>An effective tool for discovering differentially expressed genes (DEGs) related to late blight (LB) resistance is the transcriptome sequencing of potatoes. The aim of this study was to compare transcriptome expression analysis in incompatible and compatible interactions via high-throughput sequencing. Furthermore, we performed a bioinformatics analysis to screen a large number of specific transcription factors (TFs) and DEGs linked to <i>Phytophthora infestans</i> infection. Two locally cultivated potato varieties were chosen from evaluation assays conducted in two consecutive seasons and based on the disease severity (DS) values. These varieties were the highly resistant Jelly (HR) to <i>P. infestans</i> and the moderately susceptible Annabelle (MS). Ribonucleic acid-sequencing (RNA-seq) was achieved for the two varieties with their controls through the BGISEQ-500 sequencing platform. The RNA-seq analysis identified <i>P. infestans</i>-responsive genes and their expression in potatoes. The mechanism of the response of these cultivars to the <i>P. infestans</i> pathogen by TFs and DEG genes, which play an important role in defense response, was investigated. The Gene Ontology (GO) analysis classified 46,248 unigenes in the HR and 26,921 unigenes in MS into the following three categories: biological process, cellular component, and molecular functions. More genes were responsible for the cellular component category, biological process, and molecular functions in HR compared to MS. Moreover, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that the significantly enriched DEGs were included in the plant–pathogen interaction, biosynthesis of secondary metabolites, and ribosome. In addition, 1874 transcription factor genes belonging to 85 families were indicated in the DEGs, of which MYB and AP2-EREBP genes were the most abundant. Besides, multiple genes related to LB resistance showed differential expression during infection. It also sheds light on the molecular mechanisms behind potato resistance to <i>P. infestans</i> infection.</p>","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study aimed to uncover the structure and diversity of the fungal and bacterial communities associated with <i>B. striata</i>. Bioinformatics, biocontrol and biochemical experiments were carried out. In terms of relative abundance of the top 15 phyla of microbial species, tenericutes in stems (58.74%) and roots (39.36%) showed the highest relative abundance, while cyanobacteria in leaves presented the most (64.53%). At the genus level, there were 32 genera of bacteria detected in three tissues. <i>Sphingomonas</i> showed relative abundances in leaves (41.54%) and stems (22.68%), while <i>Paraburkholderia</i> showed the highest relative abundance in roots (20.87%). In contrast, the dominant genera of the fungi were <i>Melampsora</i> (28.55–43.61%) and <i>Cryptococcus</i> (6.1-25.56%) among the top 15 genera of fungi species. Twenty microorganisms were obtained from roots, stems, and leaves and isolated, which also confirmed the results of the bioinformatics analysis. The isolated <i>Bacillus velezensis</i> exhibits the capability to enhance both the growth and nutrient accumulation of <i>B. striata</i>. Additionally, <i>B. velezensis</i>, along with its fermentation products, contributes to the improvement of antioxidant enzyme activity. Notably, there are variations in the species and abundance of microflora present in the leaves, stems, and roots of <i>B. striata</i> at both the phylum and genus levels. The components of the microbial flora that were isolated and identified align with the results obtained from bioinformatic analyses. It is noteworthy that <i>B. velezensis</i> exerts a positive impact on the increase in yield of <i>B. striata</i>. This work provides important insights into <i>B. striata</i>-associated microorganisms that are essential for promoting growth and disease resistance by revealing the complex structure and variety of fungal and bacterial communities.</p>","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140565098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
