Pair-rule genes in the wasp Nasonia function as in Drosophila in patterning anterior segments, and similar to ancestral insects in patterning posterior segments, illustrating a mixed-mode transition state between short and long germ embryogenesis.
Identification of two arbuscular mycorrhiza-specific lipid biosynthesis mutants and fatty acid transfer experiments reveal that host plant lipids are transferred to symbiotic fungi and needed for their development.
Variation in the gene NaMPK4 in plant populations increases reproductive yield, an effect which appears to be independent of soil water availability, neighbor-scale interactions and associations with arbuscular mycorrhizal fungi.
The general transcription elongation factor NusG functions as an intrinsic termination factor in Bacillus subtilis and together with NusA coordinates global gene expression including the motility regulon.
Mitogen-activated protein kinase phosphatase 1 (DUSP1) deficiency causes early redox imbalance and increased inflammatory response in the cochlea, leading to cell loss and progressive neurosensory hearing loss.
