Distribution and Research Advances of Citrus tristeza virus
Published 2012-03-01Get full textCitrus tristeza virus (CTV) is one of the most important causal agents of citrus diseases and exists as numerous strains. CTV is replicated in phloem cells of plants within the family Rutaceae and is transmitted by a few of aphid species. CTV epidemics have caused death of millions of citrus trees i...

Development of a sensitive and reliable droplet digital PCR assay for the detection of ‘Candidatus Liberibacter asiaticus’
Published 2018-02-01Get full textCitrus Huanglongbing (HLB, yellow shoot disease) is one of the most serious citrus diseases worldwide. To better improve the detection sensitivity, a droplet digital PCR (ddPCR) assay was developed for the rapid detection of ‘Candidatus Liberibacter asiaticus’ (Las), the putative causal agent of HLB...

Small RNA deep sequencing reveals full-length genome of Citrus yellow vein clearing virus in Chongqing, China
Published 2017-02-01Get full textTo identity the potential pathogen associated with the yellow vein clearing symptom on lemon trees, the profiles of virus-derived small interfering RNAs from citrus samples were obtained and analyzed by deep sequencing method in this study. Twenty-seven contigs almost cover the full length genome of...

Decreasing detection frequency of MITE (MCLas-A) in the population of ‘Candidatus Liberibacter asiaticus’ recently collected in southern China
Published 2020-10-01Get full textAn active miniature inverted-repeat transposable element (MITE), MCLas-A, was previously identified from ‘Candidatus Liberibacter asiaticus’ known to be associated with citrus Huanglongbing (HLB, yellow shoot disease). To explore the recent transposition status of MCLas-A, 389 ‘Ca. L. asiaticus’ str...

Development and pathogenicity analysis of full-length infectious cDNA clones of citrus yellow mottle-associated virus in citrus plants
Published 2023-10-01Get full textCitrus yellow mottle-associated virus (CiYMaV) belonging to the subgenus Mandarivirus within the genus Potexvirus, was first identified in 2018 from Pakistan (CiYMaV-PK), where it is endemic in several regions. Here, three full-length cDNA clones (pCiYMaV-FL-1, pCiYMaV-FL-18, and pCiYMaV-FL-22) corr...

High genetic variation and recombination events in the vicinity of non-autonomous transposable elements from ‘Candidatus Liberibacter asiaticus’
Published 2015-10-01Get full textTwo miniature inverted-repeat transposable elements (MITEs), MCLas-A and MCLas-B, were recently identified from ‘Candidatus Liberibacter asiaticus’ known to be associated with citrus Huanglongbing (HLB, yellow shoot disease). MCLas-A was suggested as an active MITE because of its mobility. The immed...

A 2-bp frameshift deletion at GhDR, which encodes a B-BOX protein that co-segregates with the dwarf-red phenotype in Gossypium hirsutums L.
Published 2023-07-01Get full textPlant architecture and leaf color are important factors influencing cotton fiber yield. In this study, based on genetic analysis, stem paraffin sectioning, and phytohormone treatments, we showed that the dwarf-red (DR) cotton mutant is a gibberellin-sensitive mutant caused by a mutation in a single...

A rapid multiplication system for ‘Candidatus Liberibacter asiaticus’ through regeneration of axillary buds in vitro
Published 2022-06-01Get full text‘Candidatus Liberibacter asiaticus (CLas)’, which causes citrus Huanglongbing (HLB) disease, has not been successfully cultured in vitro to date. Here, a rapid multiplication system for CLas was established through in vitro regeneration of axillary buds from CLas-infected ‘Changyecheng’ sweet orange...
