“…However, none of these works suggested the exclusion of P. wallichii from Pueraria . The previous study of Pueraria with other phaseoloid genera described Haymondia as a distinct phylogenetic lineage . Based on the electrochemical profile recorded for Haymondia wallichii , it is necessary to further study its molecular phylogenetics.…”

Electrochemical profiles of Pueraria bouffordii, P. montana var. lobata, P. montana var. montana, P. montana var. thomsonii, Haymondia wallichii, Teyleria stricta and Toxicopueraria yunnanensis were recorded from leaf tissue after different solvent extractions. The voltammetric data recorded after different solvent extractions can be derived as patterns for species identification. The electrochemical behavior of plant tissue contains its electrochemical active compounds profile. As the distribution of chemical compounds in plants is controlled by genes, these profiles can reflect differences at the genetic level between species. The dendrogram deduced from the electrochemical profile has been used for polyphyly analysis. The result suggests the Teyleria stricta showed very distant relationships with other species. P. montana var. lobata, P. montana var. montana and P. montana var. thomsonii showed a close relationship because they were varietas. Interestingly, H. wallichii showed a close infrageneric relationship within these species, which disagrees with other morphological studies. In addition, the result also provides insight into phylogenetic status of the regionally Toxicopueraria yunnanensis.

Extrafloral nectaries in Leguminosae: phylogenetic distribution, morphological diversity and evolution

et al. 2019

Extrafloral nectaries (EFNs) mediating ecologically important ant–plant protection mutualisms are especially common and unusually diverse in the Leguminosae. We present the first comprehensively curated list of legume genera with EFNs, detailing and illustrating their systematic and phylogenetic distributions, locations on the plant, morphology and anatomy, on the basis of a unified classification of EFN categories and a time-calibrated phylogeny, incorporating 710 of the 768 genera. This new synthesis, the first since Mckey (1989)’s seminal paper, increases the number of genera with EFNs to 153 (20% of legumes), distributed across subfamilies Cercidoideae (1), Detarioideae (19), Caesalpinioideae (87) and Papilionoideae (46). EFNs occur at nine locations, and are most prevalent on vegetative plant parts, especially leaves (74%) and inflorescence axes (26%). Four main categories (with eight subcategories) are recognised and include the following: formless, trichomatic (exposed, hollow), parenchymatic (embedded, pit, flat, elevated) and abscission zone EFNs (non-differentiated, swollen scars). Phylogenetic reconstruction of EFNs suggests independent evolutionary trajectories of different EFN types, with elevated EFNs restricted almost exclusively to Caesalpinioideae (where they underwent spectacular morphological disparification), flat EFNs in Detarioideae, swollen scar EFNs in Papilionoideae, and Cercidoideae is the only subfamily bearing intrastipular EFNs. We discuss the complex evolutionary history of EFNs and highlight future research directions.
