Aeschynomene (jointvetch)

Aeschynomene is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. They are known commonly as jointvetches. These legumes are most common in warm regions and many species are aquatic. The genus as currently circumscribed is paraphyletic and it has been suggested that the subgenus Ochopodium be elevated to a new genus within the Dalbergieae, though other changes will also be required to render the genus monophyletic.

Aeschynomene evenia: shrubby jointvetch

The legume genus Aeschynomene L. includes approximately 150 tropical and subtropical species, part of them having a semi-aquatic lifestyle. Some hydrophytic Aeschynomene species display unusual symbiotic features such as stem nodulation and the presence of a Nod factor-independent infection process with some Bradyrhizobium strains. To decipher the mechanisms of this original symbiotic process, Aeschynomene evenia has emerged as a new model legume because of its advantageous genetic and developmental characteristics for molecular genetics. A. evenia (2n=20, 400 Mb/1C) is an autogamous diploid species that is annual or short-lived perennial, consisting of various genotypes.

Aeschynomene evenia accessions

CIAT22838 (Malawi)
The sequenced A. evenia genotype is an inbred line produced by IRD from the accession CIAT22838 originating from Malawi. 94% of the 400 Mb genome was assembled, 80% anchored to the 10 A. evenia chromosomes and 32,667 protein-coding genes predicted, providing a platform for comparative genomics and analysis of the nitrogen-fixing symbiosis in legumes.
