Analytical Model for Pulsed-Laser Induced Mode-Mismatched Dual-Beam Thermal Lens Spectroscopy in Liquids.

Analytical models are very important to understand physical, chemical, and biological phenomena. In many cases, obtaining an analytical model is a complex, even an impossible task. In this work, an analytical model for thermal lens spectroscopy has been developed.

The origin of bird pollination in Macaronesian Lotus (Loteae, Leguminosae).

The four red-flowered, apparently bird-pollinated Lotus species from the Canary Islands have previously been classified in their own genus, Rhyncholotus. Currently, they are considered as a separate section within genus Lotus, distinct from other herbaceous Canarian congeners which are yellow-flowered and bee-pollinated. A combined analysis of four nuclear regions (including ITS and three homologues of CYCLOIDEA) and three plastid regions (CYB6, matK and trnH-psbA) nests the four bird-pollinated species within a single extant species of bee-pollinated Lotus (L.

Evolution of petal epidermal micromorphology in Leguminosae and its use as a marker of petal identity.

Background And Aims: The legume flower is highly variable in symmetry and differentiation of petal types. Most papilionoid flowers are zygomorphic with three types of petals: one dorsal, two lateral and two ventral petals. Mimosoids have radial flowers with reduced petals while caesalpinioids display a range from strongly zygomorphic to nearly radial symmetry.

Bird-pollinated flowers in an evolutionary and molecular context.

Evolutionary shifts to bird pollination (ornithophily) have occurred independently in many lineages of flowering plants. This shift affects many floral features, particularly those responsible for the attraction of birds, deterrence of illegitimate flower visitors (particularly bees), protection from vigorous foraging by birds, and accurate placement of pollen on bird's bodies. Red coloration appears to play a major role in both bee-deterrence and bird-attraction.

Legume comparative genomics: progress in phylogenetics and phylogenomics.

The legumes are the focus of numerous rapidly expanding genomic projects, all of which involve members of one part of the Leguminosae, the subfamily Papilionoideae. This subfamily is monophyletic, and recent studies concur on a series of clades within it that are well supported and have received informal names. These include the Cladrastis clade, the genistoids (including Lupinus), the mirbelioids, the dalbergioids (including Arachis), the millettioids (including Glycine and Phaseolus), and the hologalegina (galegoid) legumes, which comprise the robinioids (including Lotus) and the inverted repeat loss (IRL) clade (including Medicago and Pisum).
