Draft genome sequence resource of the citrus stem-end rot fungal pathogen Lasiodiplodia theobromae CITRA15

Abstract

Lasiodiplodia theobromae is a fungal pathogen associated with perennial tropical fruit plants worldwide. In citrus, L. theobromae causes stem-end rot (Diplodia stem-end rot), a damaging postharvest disease that is aggravated when trees are also infected with the citrus greening bacteria ‘Candidatus Liberibacter asiaticus’. Due to the latent infection of L. theobromae during the preharvest stage, it becomes difficult to control the disease by chemical or physical treatment. In the current study, we sequenced and assembled strain CITRA15, the first genome of L. theobromae obtained from diseased Citrus paradise ‘Flame’ grapefruit in Florida, and thereby provided a genomic resource for future research on diagnostics, and postharvest and preharvest disease management of citrus and other fruit crops.
