Two TAL Effectors of Xanthomonas citri pv. malvacearum Induce Water Soaking by Activating GhSWEET14 Genes in Cotton.

ABSTRACT: Bacterial blight of cotton (BBC) caused by Xanthomonas citri pv. malvacearum (Xcm) is an important and destructive disease affecting cotton plants. Transcription activator-like effectors (TALEs) released by the pathogen regulate cotton resistance to the susceptibility. In this study, we sequenced the whole genome of Xcm Xss-V₂-18 and identified eight tal genes: seven on the plasmids and one on the chromosome. Deletion and complementation experiments of Xss-V₂-18 tal genes demonstrated that Tal1b is required for full virulence on cotton. Transcriptome profiling coupled with TALE-binding element prediction revealed that Tal1b targets GhSWEET14A04/D04 and GhSWEET14D02 simultaneously. Expression analysis confirmed the independent inducibility of GhSWEET14A04/D04 and GhSWE
