Cuing environmental responses in fungi

Fungi can sense environmental signals and react accordingly, changing their development, direction of growth, and metabolism. Sensory perception lies at the heart of adaptation to changing conditions, and helps fungi to improve ...

Salmon genome collaboration published in Nature

SFU professor Willie Davidson is part of an international research team shedding new light on genome evolution. The researchers have established a "human" quality sequence of the Atlantic salmon genome that is now available ...

Mysteries of bony fish genome evolution

As the 20th-century novelist Joseph Conrad famously wrote, "It's only those who do nothing that make no mistakes, I suppose," and Nature is very busy, so she makes lots of them. But as a genius, she can use them to advantage. ...

How yeast doubled its genome—by mating between species

The common baker's yeast (Saccharomyces cerevisiae) is used to make bread, wine and beer, and is the laboratory workhorse for a substantial proportion of research into molecular and cell biology. It was also the first non-bacterial ...

Some plants regenerate by duplicating their DNA

When munched by grazing animals (or mauled by scientists in the lab), some herbaceous plants overcompensate - producing more plant matter and becoming more fertile than they otherwise would. Scientists say they now know how ...

A-maize-ing double life of a genome

Early maize farmers selected for genes that improved the harvesting of sunlight, a new detailed study of how plants use 'doubles' of their genomes reveals. The findings could help current efforts to improve existing crop ...
