[Q]: Abstract: The DELLA proteins GAI, RGA, RGL1 and RGL2 in Arabidopsis are plant growth repressors, repressing diverse developmental processes. Studies have shown that gibberellin (GA) attenuates the repressive function of DELLA proteins by triggering their degradation via the proteasome pathway. However, it is not known if GA-induced protein degradation is the only pathway for regulating the bioactivity of DELLA proteins. We show here that tobacco BY2 cells represent a suitable system for studying GA signaling. RGL2 exists in a phosphorylated form in BY2 cells. RGL2 undergoes GA-induced degradation, and this process is blocked by proteasome inhibitors and serine/threonine phosphatase inhibitors; however, serine/threonine kinase inhibitors had no detectable effect, suggesting that dephosphorylation of serine/threonine is probably a prerequisite for degradation of RGL2 via the proteasome pathway. Site-directed substitution of all 17 conserved serine and threonine residues showed that six mutants (RGL2(S441D, RGL2(S542D), RGL2(T271E), RGL2(T319E), RGL2(T411E) and RGL2(T535E)) mimicking the status of constitutive phosphorylation are resistant to GA-induced degradation. This suggests that these sites are potential phosphorylation sites. A functional assay based on the expression of GA 20-oxidase revealed that RGL2(T271E) is probably a null mutant, RGL2(S441D), RGL2(S542D), RGL2(T319E) and RGL2(T411E) only retained about 4-17% of the activity of the wild type RGL2, whereas RGL2(T535E) retained about 66% of the activity of the wild type RGL2. However, expression of GA 20-oxidase in BY2 cells expressing these mutant proteins is still responsive to GA, suggesting that the stabilization of RGL2 protein is not the only pathway for regulating its bioactivity..

[Q]: Abstract: Standard virulence evolution theory assumes that virulence factors are maintained because they aid parasitic exploitation, increasing growth within and/or transmission between hosts. An increasing number of studies now demonstrate that many opportunistic pathogens (OPs) do not conform to these assumptions, with virulence factors maintained instead because of advantages in non-parasitic contexts. Here we review virulence evolution theory in the context of OPs and highlight the importance of incorporating environments outside a focal virulence site. We illustrate that virulence selection is constrained by correlations between these external and focal settings and pinpoint drivers of key environmental correlations, with a focus on generalist strategies and phenotypic plasticity. We end with a summary of key theoretical and empirical challenges to be met for a fuller understanding of OPs..

[Q]: Abstract: The quantification and characterization of circulating immune cells provide key indicators of human health and disease. To identify the relative effects of environmental and genetic factors on variation in the parameters of innate and adaptive immune cells in homeostatic conditions, we combined standardized flow cytometry of blood leukocytes and genome-wide DNA genotyping of 1,000 healthy, unrelated people of Western European ancestry. We found that smoking, together with age, sex and latent infection with cytomegalovirus, were the main non-genetic factors that affected variation in parameters of human immune cells. Genome-wide association studies of 166 immunophenotypes identified 15 loci that showed enrichment for disease-associated variants. Finally, we demonstrated that the parameters of innate cells were more strongly controlled by genetic variation than were those of adaptive cells, which were driven by mainly environmental exposure. Our data establish a resource that will generate new hypotheses in immunology and highlight the role of innate immunity in susceptibility to common autoimmune diseases. Both environmental factors and genetic factors influence human immunity. Albert and colleagues leverage data from the Milieu Interieur Consortium to comprehensively describe the effects of lifestyle, environment and genetics on human innate and adaptive immunity..
