Towards an ecological understanding of biological nitrogen fixation
N limitation to primary production and other ecosystem processes is widespread. To understand the causes and distribution of N limitation, we must understand the controls of biological N fixation.Expand

Legumes evolved about 60 million years ago (Ma), and nodulation 58 Ma. Nonnodulation remains common in Caesalpinioideae, with smaller numbers in Mimosoideae and Papilionoideae. The first type ofExpand

Legume-nodulating betaproteobacteria: diversity, host range, and future prospects.
Rhizobia form specialized nodules on the roots of legumes (family Fabaceae) and fix nitrogen in exchange for carbon from the host plant. Although the majority of legumes form symbioses with membersExpand

The dalbergioid legumes (Fabaceae): delimitation of a pantropical monophyletic clade.
A monophyletic pantropical group of papilionoid legumes, here referred to as the "dalbergioid" legumes, is circumscribed to include all genera previously referred to the tribes Aeschynomeneae andExpand

Burkholderia species are ancient symbionts of legumes.
Burkholderia has only recently been recognized as a potential nitrogen-fixing symbiont of legumes, but we find that the origins of symbiosis in Burkholderia are much deeper than previously suspected.Expand

Organic matter in soil particle size and density fractions from maize and legume cropping systems
Soil organic matter (SOM) plays an essential role in biologically-mediated nutrient availability. There is, however, a lack of functionally-defined measures of SOM. We analysed C and N inExpand

A new subfamily classification of the leguminosae based on a taxonomically comprehensive phylogeny
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supportedExpand
