Evolutionary Diversification across the legume landscape: from order to genus

As the old adage states: Variety is the spice of life! – and legumes are no exception. Be they morphological, chemical, or genetic, the evolutionary marvels that have arisen through diversification within the legume family are unique and varied, demonstrated by such phenomenona as rapid species diversification within the Astragalus + Oxytropis clade, the largest biotic clade of life inclusive of ~3500 species, evolution of the all-important chloroplast from the perspective of orders down to genera, and speciation, phylogeny, and morphological evolution within key genera such as Cladrastis, Chamaecrista, and Rhynchosia. This symposium brings together researchers studying the diversification of legumes from molecules to morphologies to detail the impacts of evolution on legume diversity. By investigating evolution from order to genus, the evolutionary mechanisms and marvels that have resulted in the diverse legume of the world are investigated.
