Transcriptome Analysis of Chenopodium album in Response to Infection by Botrytis Strain HZ-011
Year: 2025

Abstract: This study conducted a transcriptome sequencing analysis of the interaction between Chenopodium album and Botrytis strain HZ-011 to identify genes involved in the response to fungal infections and elucidate the molecular mechanisms underlying the interaction. High-throughput RNA-seq technology was employed to analyze the transcriptomes of C. album leaves at 1, 4, and 5 days post-inoculation (dpi) with Botrytis strain HZ-011. The results revealed 11,645 differentially expressed genes (DEGs) at 1 dpi, including 7399 upregulated and 4246 downregulated genes; 11,285 DEGs at 4 dpi (7801 upregulated and 3484 downregulated); and 9976 DEGs at 5 dpi (7723 upregulated and 2253 downregulated). GO functional analysis indicated that downregulated DEGs were significantly enriched in chloroplast and plastid functional expression at 1, 4, and 5 dpi. Following infection by Botrytis strain HZ-011, downregulated genes were significantly enriched in pathways related to photosynthesis, including photosynthetic pathways, light-harvesting antenna proteins, and carotenoid biosynthesis. This suggests that the photosynthetic process in C. album was markedly inhibited, disrupting nutrient supply and leading to herbicidal effects. Notably, genes such as PSB28, PSBP, CAP10A, and CRTL-E-1 were significantly enriched in these pathways, indicating their potential roles in the herbicidal mechanism. These findings provide a foundation for understanding the herbicidal activity of strain HZ-011 and identifying potential targets for developing novel microbial herbicides.
