Sibling care is a hallmark of the social insects, but its evolution remains challenging to explain. The hypothesis that sibling care evolved from ancestral maternal care in the primitively eusocial insects has been elaborated to involve heterochronic changes in gene expression. This elaboration lead...

During the nest-founding phase of the bumble bee colony cycle, queens undergo striking changes in maternal care behavior. Early in the founding phase, prior to the emergence of workers in the nest, queens are reproductive and also provision and feed their offspring. However, later in the founding ph...

The relationship between sequence variation and phenotype is poorly understood. Here, we use metabolomic analysis to elucidate the molecular mechanism underlying the filamentous phenotype of E. coli strains that carry destabilizing mutations in dihydrofolate reductase (DHFR). We find that partial lo...

ppcA is a member of a family of small, periplamic c-type cytochromes in Geobact sulfurreducens. The ppcA mutant displays displays a growth defect on ferric citrate medium, but the mutant has been adapted to grow to near wild-type levels on ferric citrate. The aim of this study was to elucidate gen...
