Abstract:Leaf margins are complex plant morphological features and contribute to the diversity of leaf shapes which effect on plant structure, yield and adaptation. Although several regulators of leaf margins have been identified, the genetic basis of natural variation therein has not been fully elucidated. We first profiled two distinct types (serration and smooth) of leaf morphology using the persistent homology mathematical framework (PHMF) in poplar. Combined genome-wide association studies (GWAS) and expression qu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
