AI Article Synopsis

  • The study focuses on the impact of pathogenic strains on common bean plants, exploring how they use a Type III Secretion System to inject effectors that disturb plant defense mechanisms.
  • The experiment examined the transcriptomic responses of one susceptible (Flavert) and one resistant (Vezer) bean cultivar after inoculation with both a virulent strain and its T3SS-defective mutant.
  • The results yielded a comprehensive dataset with 36,978 transcripts available in the NCBI Gene Expression Omnibus for further research on how these bacterial effectors influence plant cellular functions.

Article Abstract

pv. () and pv. () are responsible for the Common Bacterial Blight (CBB), a major common bean () disease. The pathogenicity of and is known to be dependent upon a functional Type III Secretion System (T3SS) allowing the injection of numerous bacterial Type III Effectors (T3Es) into plant cells. T3Es have been described as able to disrupt plant defence and manipulate plant metabolism. In this work we described the transcriptomic response of one susceptible (Flavert) and one resistant (Vezer) cultivars of to the inoculation of the virulent strain CFBP4885 or its avirulent T3SS-defective mutant (CFBP13802). Leaves of both bean cultivars were infiltrated with water or bacterial suspensions. Inoculated leaves were sampled at 24 or 48 h post inoculation (hpi). The experiment was independently repeated three times for total RNA extraction and sequencing analysis. Library construction and total RNA sequencing were performed with BGISEQ-500 at Beijing Genomics Institute (BGI, Hong-Kong), generating an average of 24M of paired-end reads of 100bp per sample. FastQC was used to check reads quality. Mapping analyses were made using a quasi-mapping alignment from Salmon (version 1.2.1) against the reference genome (version 2.1), revealing the expression profiles of 36,978 transcripts in leaf tissues. Fastq raw data and count files from 36 samples are available in the Gene Expression Omnibus (GEO) repository of the National Center for Biotechnology Information (NCBI) under the accession number GSE271236. This dataset is a valuable resource to investigate the role of T3Es in subverting the cellular functions of bean.
