Submergence of the filamentous Zygnematophyceae Mougeotia induces differential gene expression patterns associated with core metabolism and photosynthesis

Protoplasma. 2021 Dec 22. doi: 10.1007/s00709-021-01730-1. Online ahead of print. ABSTRACT The streptophyte algal class Zygnematophyceae is the closest algal sister lineage to land plants. In nature, Zygnematophyceae can grow in both terrestrial and freshwater habitats and how they do this is an important unanswered question. Here, we studied what happens to the zygnematophyceaen alga …

Author Correction: Genomic analysis finds no evidence of canonical eukaryotic DNA processing complexes in a free-living protist

Nat Commun. 2021 Dec 16;12(1):7350. doi: 10.1038/s41467-021-27605-w. NO ABSTRACT PMID:34916502 | DOI:10.1038/s41467-021-27605-w

Investigation of the impact of commonly used medications on the oral microbiome of individuals living without major chronic conditions

PLoS One. 2021 Dec 9;16(12):e0261032. doi: 10.1371/journal.pone.0261032. eCollection 2021. ABSTRACT BACKGROUND: Commonly used medications produce changes in the gut microbiota, however, the impact of these medications on the composition of the oral microbiota is understudied. METHODS: Saliva samples were obtained from 846 females and 368 males aged 35-69 years from a Canadian population cohort, the …

Biological and physico-chemical mechanisms accelerating the acclimation of Mn-removing biofilters

Water Res. 2021 Oct 23;207:117793. doi: 10.1016/j.watres.2021.117793. Online ahead of print. ABSTRACT This study investigated treatment strategies which accelerated the acclimation of new Mn-removing biofilters to help utilities respond to changing Mn regulations, such as the recent introduction of a health-based maximum acceptable concentration and a reduction in the aesthetic objective for Mn in drinking …

Genomic analysis finds no evidence of canonical eukaryotic DNA processing complexes in a free-living protist

Nat Commun. 2021 Oct 14;12(1):6003. doi: 10.1038/s41467-021-26077-2. ABSTRACT Cells replicate and segregate their DNA with precision. Previous studies showed that these regulated cell-cycle processes were present in the last eukaryotic common ancestor and that their core molecular parts are conserved across eukaryotes. However, some metamonad parasites have secondarily lost components of the DNA processing and …

RNA-Seq analysis reveals potential regulators of programmed cell death and leaf remodelling in lace plant (Aponogeton madagascariensis)

BMC Plant Biol. 2021 Aug 13;21(1):375. doi: 10.1186/s12870-021-03066-7. ABSTRACT BACKGROUND: The lace plant (Aponogeton madagascariensis) is an aquatic monocot that develops leaves with uniquely formed perforations through the use of a developmentally regulated process called programmed cell death (PCD). The process of perforation formation in lace plant leaves is subdivided into several developmental stages: pre-perforation, …

Shifts in amino acid preferences as proteins evolve: a synthesis of experimental and theoretical work

Protein Sci. 2021 Jul 28. doi: 10.1002/pro.4161. Online ahead of print. ABSTRACT Amino acid preferences vary across sites and time. While variation across sites is widely accepted, the extent and frequency of temporal shifts are contentious. Our understanding of the drivers of amino acid preference change is incomplete: To what extent are temporal shifts driven …

Gut bacterial gene changes following pegaspargase treatment in pediatric patients with acute lymphoblastic leukemia

Leuk Lymphoma. 2021 Jul 19:1-12. doi: 10.1080/10428194.2021.1953006. Online ahead of print. ABSTRACT Treatment of pediatric acute lymphoblastic leukemia (ALL) with pegaspargase exploits ALL cells dependency on asparagine. Pegaspargase depletes asparagine, consequentially affecting aspartate, glutamine and glutamate. The gut as a confounding source of these amino acids (AAs) and the role of gut microbiome metabolism of …

Correction to: A multi-OMIC characterisation of biodegradation and microbial community succession within the PET plastisphere

Microbiome. 2021 Jul 6;9(1):155. doi: 10.1186/s40168-021-01120-y. NO ABSTRACT PMID:34229759 | DOI:10.1186/s40168-021-01120-y

A multi-OMIC characterisation of biodegradation and microbial community succession within the PET plastisphere

Microbiome. 2021 Jun 21;9(1):141. doi: 10.1186/s40168-021-01054-5. ABSTRACT BACKGROUND: Plastics now pollute marine environments across the globe. On entering these environments, plastics are rapidly colonised by a diverse community of microorganisms termed the plastisphere. Members of the plastisphere have a myriad of diverse functions typically found in any biofilm but, additionally, a number of marine plastisphere …
