Toward understanding the catalytic mechanism for two classes of bacterial phospholipid N‐methyltransferases

open access: yesThe FEBS Journal, EarlyView.
Phospholipid N‐methyltransferases (Pmts) synthesize phosphatidylcholine in many bacteria. In this study, we compared the catalytic mechanisms of two bacterial Pmt classes: the Rhodobacter (R‐) and the Sinorhizobium (S‐) type. Representative enzymes for each class were derived from Rubellimicrobium thermophilum and Agrobacterium tumefaciens ...

Mechanisms underpinning the progression of nondysplastic Barrett's oesophagus to cancer

open access: yesThe FEBS Journal, EarlyView.
Barrett's oesophagus confers a low but significant cancer risk. The condition is common but we do not have effective biomarkers to identify susceptible patients. We believe that there is no single factor that determines cancer risk and an understanding of the combinations of interactions (via gene expression and natural selection) between the Barrett's

Empirical prediction of organic matter digestibility in grasses, legumes and their mixtures from dairy farms in Atlantic Spain

open access: yesGrassland Science, EarlyView.
Abstract This study characterized the chemical composition and organic matter digestibility (OMD) of herbage from commercial dairy farms in Galicia (NW Spain), a humid‐temperate Atlantic region, and developed empirical prediction equations for OMD based on routine wet‐chemistry traits.

Non‐crop habitats and cover crops as potential ecological corridors and stepping stones for autumnal migrating hoverflies

open access: yesInsect Conservation and Diversity, EarlyView.
Mass migration of hoverflies was observed near Prague city in a highly agricultural landscape, representing only the second record of hoverfly migration in the Czech Republic. This rare observation was likely driven by the need to rest, shelter and replenish energy, although most flowers had already finished blooming.

Canadian boreal restored mining sites sustain diverse pollinator communities, including species of conservation concern

open access: yesInsect Conservation and Diversity, EarlyView.
Revegetated mine tailing storage facilities support pollinator abundance, diversity, richness and evenness comparable to recently logged boreal forest sites. Agronomic and spontaneous revegetation strategies host similar pollinator and Bombus community structures, indicating multiple rehabilitation approaches can effectively restore pollinator habitat.

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

open access: yesInsect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

The ZmRACK1–ZmCDPK7–ZmAPX1 module regulates plant antiviral immunity

open access: yesJournal of Integrative Plant Biology, EarlyView.
In maize, ZmRACK1 acts as a scaffold protein that bridges the cyclin‐dependent kinase ZmCDPK7 and the ascorbate peroxidase ZmAPX1, promoting ZmAPX1 activity to mitigate MCMV infection. Upon viral infection, P31 obstructs formation of the ZmRACK1‐ZmCDPK7‐ZmAPX1 complex, inhibiting ZmCDPK7‐mediated ZmAPX1 activity and promoting reactive oxygen species ...
