Two genes better than one for important plant pest

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have revealed a novel molecular mechanism that triggers plant infection by Pseudomonas syringae, the bacteria responsible for bacterial ...

Getting around gene loss

Genes ‘knocked out’ experimentally in metabolic networks of the model plant species, Arabidopsis thaliana (Fig. 1), are compensated for by duplicate genes or alternative synthetic pathways, according to research ...

Traces of early Native Americans -- in sunflower genes

New information about early Native Americans' horticultural practices comes not from hieroglyphs or other artifacts, but from a suite of four gene duplicates found in wild and domesticated sunflowers.

Spare gene is fodder for fishes' evolution

Scientists have suspected that spare parts in the genome—extra copies of functional genes that arise when genes or whole genomes get duplicated -- might sometimes provide the raw materials for the evolution of new traits. ...
