Abstract

LOPEZ-SAN JUAN, Mireya Paloma et al. Endosymbionts associated with Diaphorina citri, vector of Candidatus Liberibacter asiaticus. Rev. Chapingo Ser.Hortic [online]. 2021, vol.27, n.1, pp.43-54.  Epub Apr 23, 2021. ISSN 2007-4034.  https://doi.org/10.5154/r.rchsh.2019.12.022.

Diaphorina citri is considered the most dangerous citrus pest because it transmits Candidatus Liberibacter asiaticus, the causal agent of Huanglongbing (HLB). Like other hemiptera insects, D. citri has developed mutualistic interactions with prokaryotic organisms known as endosymbionts. This symbiosis can be obligatory, when the interaction occurs with a primary endosymbiont, or facultative, when it is a secondary endosymbiont. Symbiosis is essential for various physiological functions, but some endosymbionts can adversely affect the psyllid's abilities. D. citri is associated with a great diversity of endosymbionts, with Candidatus Carsonella ruddii, Candidatus Profftella armatura, Candidatus Wolbachia spp. and Candidatus Liberibacter spp standing out. The aim of this review was to explore the importance and function of endosymbionts associated with D. citri, as well as their role in the transmission of Candidatus Liberibacter asiaticus.

Keywords : symbiotic relationship; prokaryotes; Candidatus Wolbachia; transmission.
