摘要： The bacterial strain HT11 isolated from broad bean (Vicia faba L.) exhibited strong antifungal activity against Botrytis fabiopsis, the causative agent of red spot disease in broad bean. To gain insights into the secondary metabolites produced by HT11,its entire genome was sequenced and subjected to comprehensive analysis. The genome comprised a single circular chromosome of 6,335,588 base pairs (bp) in length. Comparative analysis of the 16 S rRNA gene and the average nucleotide identity (ANI) confirmed the HT11 strain as a new Pseudomonas strain. The complete genome encoded 5,366 predicted open reading frames (ORFs), 66 tRNA genes and 16 rRNA genes. The total length of the annotated genes accounted for 82.93% (5,254,103/6,335,588 bp) of the complete genome. Functional categorization of the predicted ORFs revealed 24 Clusters of Orthologous Groups of proteins (COG). Fourteen gene clusters were identified with in the genome, associated with the biosynthesis of pyochelin, pyocyanin, viscosin, and tolaasin I/tolaasin F. Additionally, three gene clusters were implicated in the biosynthesis of unknown metabolites. These findings establish a foundational basis for further investigations into the interactions between Pseudomonas sp. HT11 and the pathogenic fungus Botrytis fabiopsis.
