Dual-transcriptome of post-germinating mutant lines of Arabidopsis thaliana infected by Alternaria brassicicola
Description
Alternaria brassicicola is a seed-borne pathogen causing black spot disease in Brassica crops, yet the seed defense mechanisms against this fungus remain poorly understood. Building upon recent reports that highlighted the involvement of indole pathways in seeds infected by Alternaria, this study provides transcriptomic resources to further elucidate the role of these metabolic pathways during the interaction between seeds and fungal pathogens. Using RNA sequencing, we exam-ined gene expression of glucosinolate-deficient mutant lines (cyp79B2/cyp79B3 and qko) and a camalexin-deficient line (pad3), generating a dataset from 14 samples. These samples were inoc-ulated with Alternaria or water, and collected at 3, 6, and 10 Days After Sowing to extract total RNA. Sequencing was performed using DNBseq™ technology, followed by bioinformatics anal-yses with tools such as FastQC, multiQC, Venny, Salmon software, and R packages DESeq2, ClusterProfiler and ggplot2. By providing this valuable dataset, we aim to contribute to a deeper understanding of seed defense mechanisms against Alternaria, leveraging RNA-seq for various analyses, including differential gene expression and co-expression correlation. This work serves as a foundation for a more comprehensive grasp of the interactions during seed infection and highlights potential targets for enhancing crop protection and management.
