Abstract Catalpa bungei, a fast-growing timber tree, is threatened by the lepidopteran pest Omphisa plagialis. Previous studies in our laboratory successfully generated transgenic C. bungei lines overexpressing Cry genes (Cry1Ab, Cry2A, and Cry9-2) that exhibited resistance to O. plagialis, but their potential impact on soil bacterial communities remains unclear. In this study, we analyzed nine transgenic C. bungei lines (three independent lines for each Cry gene) to characterize their rhizosphere bacterial communities using high-throughput sequencing of the 16S ribosomal DNA (rDNA) V4–V5 regions. A total of 628 amplicon sequence variants (ASVs) were shared among all transgenic and wild-type (WT) lines, forming a stable core… More >
