Anaerobic Degradation of Non-Methane Alkanes by “ Candidatus Methanoliparia” in Hydrocarbon Seeps of the Gulf of Mexico

Names
Ca. Argarchaeum Methanoliparia Ca. Syntrophoarchaeum Methanoliparum thermophilum Ts
Abstract
Oil-rich sediments from the Gulf of Mexico were found to contain diverse alkane-degrading groups of archaea. The symbiotic, consortium-forming “ Candidatus Argoarchaeum” and “ Candidatus Syntrophoarchaeum” are likely responsible for the degradation of ethane and short-chain alkanes, with the help of sulfate-reducing bacteria. “ Ca. Methanoliparia” occurs as single cells associated with oil droplets. These archae

Comparative Genomics Reveals Ecological and Evolutionary Insights into Sponge-Associated Thaumarchaeota

Abstract
Sponges represent ecologically important models to understand the evolution of symbiotic interactions of metazoans with microbial symbionts. Thaumarchaeota are commonly found in sponges, but their potential adaptations to a host-associated lifestyle are largely unknown. Here, we present three novel sponge-associated thaumarchaeal species and compare their genomic and predicted functional features with those of closely related free-living counterparts. We foun

A high-throughput system to identify inhibitors of Candidatus Liberibacter asiaticus transcription regulators

Citation

Names
Ca. Liberibacter asiaticus
Abstract
Citrus greening disease, also known as huanglongbing (HLB), is the most devastating disease of Citrus worldwide. This incurable disease is caused primarily by the bacterium Candidatus Liberibacter asiaticus and spread by feeding of the Asian Citrus Psyllid, Diaphorina citri. Ca. L. asiaticus cannot be cultured; its growth is restricted to citrus phloem and the psyllid insect. Management of infected trees includes use of broad-spectrum antibiotics, which have disadvantages. Recent work has sought

Filodia de la margarita (Dimorphotheca sinuata) asociada a Candidatus phytoplasma asteris

Citation

Names
Abstract
En Montecillo Texcoco, Estado de México se observaron plantas de margarita (<em>Dimorphotheca</em> <em>sinuata</em>) exhibiendo síntomas de filodia, virescencia y proliferación de ramas axilares putativos a los inducidos por fitoplasmas.  Por lo que el objetivo de esta investigación fue detectar el fitoplasma asociado a estos síntomas mediante PCR con los iniciadores P1/P7 y R16F2n/R2. Se detectó la presencia de fitoplasmas en tejido foliar sintomático. El producto de PCR

Analysis of Site-dependent Pinus halepensis Mill. Defoliation Caused by ‘Candidatus Phytoplasma pini’ through Shape Selection in Landsat Time Series

Citation
Trujillo-Toro, Navarro-Cerrillo (2019). Remote Sensing 11 (16)
Names
Ca. Phytoplasma pini
Abstract
High levels of ‘Candidatus Phytoplasma pini’ have produced extensive forest mortality on Pinus halepensis Mill forests in eastern Spain. This has led to the widespread levels of forest mortality. We used archival Landsat imagery and shapes algorithm implemented in the Google Earth Engine to explore the potential of the LandTrendr algorithm and its outputs, together with field observations, to analyze and predict the health status in P. halepensis stands affected by ‘Candidatus Phytoplasma pini’

Multi-omic analysis of medium-chain fatty acid synthesis byCandidatusWeimerbacter bifidus, gen. nov., sp. nov., andCandidatusPseudoramibacter fermentans, sp. nov

Abstract
ABSTRACTChain elongation is emerging as a bioprocess to produce valuable medium-chain fatty acids (MCFA; 6 to 8 carbons in length) from organic waste streams by harnessing the metabolism of anaerobic microbiomes. Although our understanding of chain elongation physiology is still evolving, the reverse β-oxidation pathway has been identified as a key metabolic function to elongate the intermediate products of fermentation to MCFA. Here, we describe two chain-elongating microorganisms that were enr
