A three-stage symbiosis forms the foundation of seagrass ecosystems.
Seagrasses evolved from terrestrial plants into marine foundation species around 100 million years ago. Their ecological success, however, remains a mystery because natural organic matter accumulation within the beds should result in toxic sediment sulfide levels. Using a meta-analysis, a field study, and a laboratory experiment, we reveal how an ancient three-stage symbiosis between seagrass, ...

What is in store for the guppy? Variation is essential to understanding the genetics underlying biological processes. The guppy provides a huge amount of natural variation that can be studied genetically. This variation has not been produced by mutagenesis screens, but instead has been shaped by natural selection. Thus, combined with emerging genomic resources, the guppy is an ideal organism fo...
متن کاملSymbiosis-independent and symbiosis-incompetent mutants of Bdellovibrio bacteriovorus 109J.
Symbiosis-independent (Sin) mutants were isolated from the symbiosis-dependent and symbiosis-competent (Sdcomp+) Bdellovibrio bacteriovorus 109J. Independently isolated Sin mutants were examined for their symbiosis competence and most were found to be comp+. Bdellovibrios comp- were selected from the Sincomp+ mutants. The Sincomp+ bdellovibrios are always at a selective disadvantage, either aga...
متن کاملElectrifying symbiosis.
A role of ion channels in the interactions between bacterial pathogens and their animal hosts is well established. In some cases, regulation of endogenous channels in the target species is disrupted by bacterial toxins, resulting in an alteration of ion flux and a perturbation of cellular function (1). In a more extreme example, hemolytic bacteria actually insert poreforming proteins into the p...
