URL http://dx.doi.org/10.1093/aob/mcs139 (free access) Individual plant species thrive in specific environments, some growing well across a wide area, others being restricted to survival in very narrow ecological niches. Within a niche, a species must compete for space, light and other resources with the same and other…

He is involved with media presentations, gives strategic and policy input, and reviews research.

Banana genome sequence in the news

The full sequence of the banana genomic DNA was published last week, giving access to the sequences of all the 36000 genes in this important crop. The publication of this information is of both applied importance, giving knowledge of the genes giving the agronomic and food-related properties, and of fundamental importance to research since it…

Trude Schwarzacher PI

Dr Trude Schwarzacher is a co-project leader of the Molecular Cytogenetics research group in the University of Leicester. Current research interests include: Wheat and related species I am studying introgression of alien chromosomes and introgression of alien chromosomes from wild species into bread wheat. In wheat and related species, we have found differences in cytosine…
