The protein CpoB regulates PBP1B activity in response to the Tol energy state, which facilitates feedback and synchronicity between envelope constriction processes during Gram-negative bacterial cell division.
Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
Hybridization and introgression blur species boundaries and broaden genetic diversity available for adaptation; and widespread introgression underpins the evolution of races of the generalist pathogen Albugo candida that specialise on different host plant species.
Specialized fungal pathogen populations infect rice varieties with contrasting immune systems co-cultivated in a traditional agro-system, indicating the relevance of crop diversity to restricting epidemics in the landscape.
An atypical subtilase protein, resulting from an alternative splicing event, mediates retention of the defence related-transcription factor MYB30 at endosomal vesicles, thus repressing Arabidopsis antibacterial immunity.
A transport mechanism is uncovered in the major drug-efflux system in E. coli involving two remote alternating-access conformational cycles, which could provide the basis for the development of allosteric inhibitors against multidrug resistance.
