Bacterial viruses are an unexpected ‘third party’ that imposes a strong predatory pressure on a bacterial pathogen during the natural course of infection in humans.
HIV vaccine-induced binding and neutralizing antibody epitope specificities were mapped at high resolution directly from polyclonal sera, overcoming shortcomings in traditional serum mapping approaches and enabling highly detailed vaccine design.
Models of plant behaviour show that flowering early in a warming world is an adaptive strategy to insulate progeny seed behaviour from the affects of climate change.
Genetic and molecular analyses identify and characterize an evolutionary battle over lysis timing wherein a bacteriophage delays lysis through lysis inhibition while a defensive phage satellite accelerates lysis.
Seed-specific and cold-induced DNA methylation is deposited in the seed progeny to form a transient and transgenerational memory of past environmental conditions to optimize seed germination timing.
