La enfermedad del permanente tomate o zebra chip cau- sada por “Candidatus Liberibacter solanacearum” (Ca. L. solanacearum), es de gran importancia en las regiones productoras México, la cual causa pérdidas entre el 60 y 100% producción. El objetivo trabajo fue evaluar efecto seis fosfitos (FOS), ácido salicílico acibenzolar s-metil sobre crecimiento cultivo severidad Ca. solanacearum. Las plan...

Huanglongbing is a devastating disease of citrus. In this study, a comprehensive profile of phloem sap amino acids (AA) in four permissive host plants of Candidatus Liberibacter asiaticus (CLas) and three non-permissive Rutaceae plants was conducted to gain a better understanding of host factors that may promote or suppress the bacterium. The AA profiles of Diaphorina citri nymphs and adults we...

BACKGROUND The Candidate Phyla Radiation (CPR) is a recently described expansion of the tree of life that represents more than 15% of all bacterial diversity and potentially contains over 70 different phyla. Despite this broad phylogenetic variation, these microorganisms appear to feature little functional diversity, with members generally characterized as obligate fermenters. Additionally, muc...

Candidatus Liberibacter asiaticus is a fastidious, phloem-inhabiting, gram-negative bacterium transmitted by Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae). The bacterium is the presumed causal agent of huanglongbing (HLB), one of the most destructive and economically important diseases of citrus. We investigated whether Las is transmitted between infected and uninfected...

Diaphorina citri is a serious insect pest of citrus and an vector Candidatus Liberibacter asiaticus (CLas) that causes Huanglongbing disease (citrus greening). In this study, we investigated the effect CLas pathogen on life history parameters D. at different temperature regimes. Our results demonstrated survival rate first to fifth instar CLas-positive CLas-negative fluctuate with change in ove...
