Comparative transcriptomic analyses of black grass (Alopecurus myosuroides) and bread wheat (Triticum aestivum) response to waterlogging
Black-grass is a problematic weed of winter wheat. We conducted controlled waterlogging studies comparing the physiology and molecular responses of both black-grass and wheat. These revealed differences in roots and aerial tissues within and between species. Molecular analyses showed that wheat mounts a robust molecular response, altering gene expression and metabolites with waterlogging, whereas black-grass showed minimal responses to waterlogging despite its apparent tolerance.
