The Cajal body (CB) is a nuclear organelle present in all eukaryotes that have been carefully studied. It is identified by the signature protein coilin and by CB-specific RNAs (scaRNAs). CBs contain high concentrations of splicing small nuclear ribonucleoproteins (snRNPs) and other RNA processing factors, suggesting that they are sites for assembly and/or posttranscriptional modification of the...

Citrus huanglongbing (HLB) is one of the most devastating citrus diseases in the world. The disease is associated with three species of Candidatus Liberibacter, „Ca. L. asiaticus‟, „Ca. L. africanus‟, and „Ca. L. americanus‟, and transmitted mainly by the Asian citrus psyllid (Diaphorina citri) and the African citrus psyllid (Trioza erytreae). Upon the first report of the disease in São Paulo, ...

Diaphorina citri Kuwayama transmits a destructive citrus disease caused by fastidious bacterium ‘Candidatus Liberibacter asiaticus’ (CLas) designated as Huanglongbing (HLB) which posed risk of detrimental threat to the Malaysian industry. All D. life stages show lumped habit on young flushes and its population fluctuations was closely related accessibility flushes. The study aimed investigate i...

Throughout the history of citrus production in Florida one of the diseases with a major impact has been the Asian form of citrus greening (HLB), which was first detected in 2005. As a response to this introduction, new survey and detection methods had to be developed utilizing field observations directed not only to corroborate symptoms already reported in the literature, but to describe any va...

Candidatus Liberibacter asiaticus (CLas) is a phloem-limited, gram-negative, fastidious bacterium that is associated with the development of citrus greening disease, also known as Huanglongbing (HLB). CLas is transmitted by the Asian citrus psyllid (ACP) Diaphorina citri, in a circulative manner. Two major barriers to transmission within the insect are the midgut and the salivary glands. We per...

Since the advent of Huanglongbing (HLB) disease, Florida’s citrus production has dropped by 70%. HLB-affected trees decline rapidly under high pH growing conditions. Limited nutrient availability at soil been speculated to be cause such rapid in trees; however, is not observed healthy trees. Therefore, objective this study was understand uptake, physiological, and molecular responses (HLY) swee...

BACKGROUND Roots are the primary site for plant-microbe interactions. Among the three root-associated layers (i.e., rhizosphere, rhizoplane, and endorhiza), the rhizoplane is a key component serving a critical gating role that controls microbial entry into plant roots. The microbial communities colonizing the three layers are believed to be gradually enriched from the bulk soil inoculum. Howeve...
