Bioinformatics Workflow for Co-Transcriptome Analysis of Plant-Bacterial Interactions

Area of Science:

• Plant-microbe interactions
• Genomics and transcriptomics
• Bioinformatics

Background:

• Understanding plant-bacterial interactions is crucial for deciphering molecular mechanisms of parasitism, commensalism, and mutualism.
• RNA sequencing (RNA-seq) allows simultaneous analysis of plant and bacterial transcriptomes during colonization.
• Existing computational workflows for co-transcriptome analysis are limited.

Purpose of the Study:

• To present a step-by-step bioinformatics pipeline for analyzing co-transcriptome landscapes in plant-bacterial interactions.
• To provide a comprehensive tool for researchers with basic command-line and R programming skills.
• To facilitate hypothesis generation regarding plant-bacterial transcriptional interplay.

Main Methods:

• Quality control and processing of raw RNA-seq data for both plant and bacterial samples.
• Statistical analysis for differential gene expression.
• Prediction of orthologous bacterial genes and functional annotation using KEGG database.
• Integration and comparative analysis across multiple bacterial strains.
• Correlation-based analysis of transcriptional dynamics between plants and bacteria.

Main Results:

• A comprehensive bioinformatics pipeline for co-transcriptome analysis in plant-bacterial interactions has been established.
• The pipeline enables detailed examination of gene expression in both host plants and colonizing bacteria.
• It facilitates comparative analysis across different bacterial strains and correlation of transcriptional dynamics.

Conclusions:

• The developed pipeline offers a valuable resource for studying plant-bacterial transcriptional interplay.
• It supports research in both pathogenic and symbiotic contexts, advancing our understanding of these interactions.
• This workflow empowers researchers to generate novel hypotheses in plant-microbe biology.
