Abstract
Foliar symptoms resembling those associated with late-season decline (LSD) disease of corn, caused by the bacteria Pantoea ananatis, were observed in commercial fields of sorghum plants in 2023 in the Texas Panhandle. Diagnosis of symptomatic tissues consistently recovered bacterial isolates that were subsequently identified, based on partial sequences of their respective 16S rRNA gene, as P. ananatis. The pathogenicity of a representative isolate on sorghum was investigated using the method of Koch’s postulate and resulted in the successful reproduction of LSD-like foliar symptoms identical to those described for corn, as well as those observed in affected sorghum fields.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
