Genomic innovations, transcriptional plasticity and gene loss underlying the evolution and divergence of two highly polyphagous and invasive Helicoverpa pest species
TLDR
The extreme polyphagy of the two heliothines is associated with extensive amplification and neofunctionalisation of genes involved in host finding and use, coupled with versatile transcriptional responses on different hosts.
Heat-evolved microalgal symbionts increase coral bleaching tolerance
TLDR
It is shown that coral stock with enhanced climate resilience can be developed through ex hospite laboratory evolution of their microalgal endosymbionts, and the more tolerant symbiosis exhibited additional higher constitutive expression of algal carbon fixation genes and coral heat tolerance genes.
Phylogenetic and Kinetic Characterization of a Suite of Dehydrogenases from a Newly Isolated Bacterium, Strain SG61-1L, That Catalyze the Turnover of Guaiacylglycerol-β-Guaiacyl Ether Stereoisomers
TLDR
A suite of dehydrogenase candidates were heterologously expressed and kinetically characterized and exhibited stereoselectivity toward the GGE stereoisomers, indicating a variety of potential applications for these enzymes in the manufacture of lignin-derived commodities.
Whole-Genome Expression Analysis in the Third Instar Larval Midgut of Drosophila melanogaster
TLDR
RNA sequencing is used to investigate whole-genome expression in subsections of third instar larval midguts of Drosophila melanogaster and analysis of the expression of gene families that are implicated in the metabolism of xenobiotics suggests that metabolism may not be uniform along the midgut.
Genomic changes associated with adaptation to arid environments in cactophilic Drosophila species
TLDR
Adaptations to new cactus hosts and hot desiccating environments were associated with periods of accelerated evolutionary change in diverse biochemistries, suggesting adaptations of this sort would be difficult to achieve in the timeframes projected for anthropogenic climate change.
Erratum to: Genomic innovations, transcriptional plasticity and gene loss underlying the evolution and divergence of two highly polyphagous and invasive Helicoverpa pest species
Upon publication of the original article [1], it was noticed that Dr Papanicolaou's surname was spelt incorrectly. The correct spelling is "Papanicolaou", as shown in the author list of this erratum.
Draft Genome Sequence of Pandoraea sp. Strain SD6-2, Isolated from Lindane-Contaminated Australian Soil
TLDR
The genome of SD6-2 was sequenced to investigate its ability to degrade δ-hexachlorocyclohexane, and the annotated genome sequence of this strain is reported.
Oxidative Catabolism of (+)-Pinoresinol Is Initiated by an Unusual Flavocytochrome Encoded by Translationally Coupled Genes within a Cluster of (+)-Pinoresinol-Coinduced Genes in Pseudomonas sp.
TLDR
Comp comparative genomics, proteomics, protein semipurification, and heterologous expression are used to identify a flavoprotein from the vanillyl alcohol oxidase/p-cresol methyl hydroxylase (VAO/PCMH) enzyme family in SG-MS2 that carries out the initial hydroxymation of (+)-pinoresinol at the benzylic carbon.
