Analysis of a Prophage Gene Frequency Revealed Population Variation of ‘Candidatus Liberibacter asiaticus’ from Two Citrus-Growing Provinces in China

Names
Ca. Liberibacter asiaticus
Abstract
Prophages are important genetic elements of bacterial genomes and are involved in lateral gene transfer, pathogenicity, environmental adaptations, and interstrain genetic variability. In this study, the sequence of a prophage terminase gene of ‘Candidatus Liberibacter asiaticus’, a bacterium associated with citrus Huanglongbing (HLB), was selected as a molecular marker to assess the genetic variation in two ‘Ca. L. asiaticus’ populations from geographically distinct provinces (Guangdong and Yun

Amycolatopsis thailandensis sp. nov., a poly(l-lactic acid)-degrading actinomycete, isolated from soil

Citation
Chomchoei et al. (2011). International Journal of Systematic and Evolutionary Microbiology 61 (4)
Names
Amycolatopsis thailandensis Amycolatopsis coloradensis Amycolatopsis alba
Abstract
A novel actinomycete that was capable of degrading poly(l-lactic acid), strain CMU-PLA07T, was isolated from soil in northern Thailand. Strain CMU-PLA07T had biochemical, chemotaxonomic, morphological and physiological properties that were consistent with its classification in the genus Amycolatopsis. 16S rRNA gene sequence analysis showed that the isolate formed a phyletic line within the genus Amycolatopsis. Strain CMU-PLA07T was most similar to Amycolatopsis coloradensis IMSNU 22096T (99.5 %

Glutathione Transferase and Cytochrome P450 (General Oxidase) Activity Levels in Candidatus Liberibacter Asiaticus-Infected and Uninfected Asian Citrus Psyllid (Hemiptera: Psyllidae)

Names
Liberibacter
Abstract
Abstract Candidatus Liberibacter asiaticus (Las) has been reported to increase the susceptibility of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), to selected insecticides. Reduced general esterase activity in Las-infected, compared with uninfected, D. citri has been proposed as a possible explanation for this difference in insecticide susceptibility. The current study was conducted to quantify glutathione transferase (GST) and cytochrome P450 (genera

Physiological role of the respiratory quinol oxidase in the anaerobic nitrite-reducing methanotroph ‘Candidatus Methylomirabilis oxyfera’

Citation

Names
Methylomirabilis oxygeniifera Ts
Abstract
The anaerobic nitrite-reducing methanotroph ‘CandidatusMethylomirabilis oxyfera’ (‘Ca.M. oxyfera’) produces oxygen from nitrite by a novel pathway. The major part of the O2is used for methane activation and oxidation, which proceeds by the route well known for aerobic methanotrophs. Residual oxygen may serve other purposes, such as respiration. We have found that the genome of ‘Ca.M. oxyfera’ harbours four sets of genes encoding terminal respiratory oxidases: two cytochromecoxidases, a third put
