The phylogenetic pattern in phytolith shape was successfully revealed by applying geometric morphometrics to 2D phytolith shape outlines, strengthening the potential of phytoliths to track the evolutionary history and paleoecology of grasses.Continue reading How much does a phytolith look like an average phytolith?
Stomatal trait variation may have evolved more in response to pathogens than climate, or climate may be affecting the traits in unexpected ways.Continue reading Stomatal traits do not determine species range via abiotic stress tolerance in Pooideae
The transfer of chromosomes and/or segments between related species can be used in the development of novel plant phenotypes and also provides an important resource both for dissecting the genetic control of important traits and gene isolation. Harper et al. describe the generation and the molecular and cytological characterization of seven monosomic substitution lines between Lolium perenne and Festuca pratensis. Parallels between the this system and cereals such as wheat and barley and the model grass Brachypodium distachyon present opportunities for a comparison across the species in terms of genotype and phenotype.Continue reading Alien introgression in Lolium and Festuca
