Interpretive Summary: In 2000, a previously unobserved inner cotton boll rot caused seed and fiber yield losses that reached 20%. Past work from our lab demonstrated that certain fungi and bacteria are responsible for the boll rot disease and these microbes are vectored by insects that feed using a piercing-sucking mechanism. Although the pathogens vary in species, they have the common ability to infect and produce the boll rot disease. Hence, we hypothesized that the cotton pathogens share a common set of genes involved in producing disease. This report provides the whole genome sequence of an infective bacterium that is associated with boll feeding by the verde plant bug, a prominent pest of cotton in South Texas. Information generated from our study is essential for understanding the boll infection process and for developing a user-friendly system to directly detect the presence of this disease in cotton fields.

Technical Abstract: Serratia species are Gram-negative bacteria consisting of isolates that can infect both animals and plants. The presented annotated genome is the first of a Serratia sp. (called CC119) that is a cotton boll pathogen. The opportunistic strain is associated with the Creontiades signatus that is a boll piercing-sucking insect.
