Soybean [Glycine max (L.) Merr.] is an economically important crop with high protein and oil contents. A range of biotic stresses constantly threaten soybean production and lead to decreases in yield and quality, but bacterial pustule caused by Xanthomonas citri pv. glycines (Xcg) is one of the most destructive diseases affecting worldwide soybean production. This review provides an extensive summary of multidisciplinary research on the soybean–Xcg interaction. First, we introduce general biological features of the causal agent Xcg as well as symptoms of the bacterial pustule disease it causes. Second, we review the geographic distribution of and genetic changes in the Xcg population over time, based on molecular evidence from recent studies. Third, we integrate several published studies to identify resistance loci against Xcg using bi-parental mapping populations and collections of germplasm along with genetic sources and molecular markers associated with resistance. Fourth, we summarize the molecular interactions between soybean and Xcg. Lastly, we discuss perspectives on future genomic research and breeding for improved resistance to Xcg in soybean.

Xanthomonas citri pv. glycines is a major pathogen of soybean in Korea. Here, we analyzed pathogenicity genes based on a comparative genome analysis of five Korean strains and one strain from the United States, 8ra. Whereas all six strains had nearly identical profiles of carbohydrate-active enzymes, they varied in diversity and number of candidate type III secretion system effector (T3SE) genes. The five Korean strains were similar in their effectors, but differed from the 8ra strain. Across the six strains, transcription activator-like effectors (TALEs) showed diverse repeat sizes and at least six forms of the repeat variable di-residue (RVD) sequences, with differences not correlated with the origin of the strains. However, a phylogenetic tree based on the alignment of RVD sequences showed two distinct clusters with 17.5 repeats, suggesting that two distinct 17.5 RVD clusters have evolved, potentially to adapt Xcg to growth on distinct soybean cultivars. The predicted effector binding elements of the TALEs fell into six groups and were strongly overlapping in sequence, suggesting evolving target specificity of the binding domains in soybean cultivars. Our findings reveal the variability and adaptability of T3SEs in the Xcg strains and enhance our understanding of Xcg pathogenicity in soybean. Full article
