Bacteria diversify
Bacteria diversify nfectious bacteria often grow in their hosts as biofilms. Blaise Boles, Matthew Thoendel, and Pradeep Singh (University of Iowa, Iowa City, IA) now report that growth in biofilms causes Pseudomonas aeruginosa bacteria to diversify. The resultant diverse populations are probably more able to cope with changing environmental conditions, providing a bacterial correlate of the re...
متن کاملCardiac 7-transmembrane-spanning domain receptor portfolios: diversify, diversify, diversify.
Enhanced signaling in myocytes by the G protein Gq has been implicated in cardiac hypertrophy and the transition to heart failure. alpha1-Adrenergic receptors (alpha1-ARs) are members of the 7-transmembrane-spanning domain (7-TM) receptor family and signal via interaction with Gq in the heart. The specific effects of a loss of alpha1-AR signaling in the heart are explored by O'Connell et al. in...
متن کاملELKS1 helps neuronal synapses diversify
Study reveals how neurons vary the properties of individual synapses by recruiting different Munc13 proteins to presynaptic active zones.
متن کاملSpeciation: Don't Fly and Diversify?
Loss of flight in Japanese carrion beetles is correlated with greater population subdivision and higher speciation rate. This reveals the complex relationship of trait evolution with dispersal power, range size and diversification.
متن کاملMicrobiome: Should we diversify from diversity?
Studies on microbiome diversity are flooding the current literature, yet lessons from ecology clearly demonstrate that diversity is just one factor to consider when analyzing an ecosystem, along with its stability, structure and function. Measures of diversity may be a useful tool for interpreting metagenomic data but the question remains as to how informative they are and what insight they may...
