Relationships of bradyrhizobia from Platypodium and Machaerium (Papilionoideae: tribe Dalbergieae) on Barro Colorado Island, Panama.
Enzyme electrophoresis and rRNA sequencing indicated that root nodule bacteria from the canopy tree Platypodium elegans and the lianas Machaerium milleflorum and Machaerium arboreum on Barro Colorado Island, Panama, were highly diverse on a local scale. A total of 11 distinct multilocus genotypes [ETs (electrophoretic types)] was found among the 33 isolates analysed. On average, ETs differed fr...
متن کاملMorphological and micromorphological characteristics of Desmodium fruits (Leguminosae: Papilionoideae).
The genus Desmodium is represented in Santa Catarina State, Brazil, by 13 species, all with lomen- taceous fruits. Shape, size and isthmus margin of loments vary, while the surface is glabrous, or covered by trichomes of different types. Morphological diversity of trichomes becomes particularly relevant to taxonomic description. The trichome types present on the surface of Desmodium fruits prov...
متن کاملFemale gametophyte development in Adesmia latifolia ( Spreng . ) Vog . ( Leguminosae – Papilionoideae )
(Female gametophyte development in Adesmia latifolia (Spreng.) Vog. (Leguminosae – Papilionoideae)). The female gametophyte has a monosporic origin and a Polygonum type development. The female gametophyte growth consumes a large part of the neighboring nucellar cells and, in the micropylar region, part of the nucellar epidermis and internal integument. The mature gametophyte is composed of only...
متن کاملVigna yadavii (Leguminosae: Papilionoideae), a new species from Western Ghats, India
A new species of Vigna Savi, subgenus Ceratotropis (Piper) Verdc., Vignayadavii S.P. Gaikwad, R.D. Gore, S.D. Randive & K.U. Garad, sp. nov. is described and illustrated here. It is morphologically close to Vignadalzelliana (Kuntze) Verdc. but differs in its underground obligate cleistogamous flowers on positively geotropic branches, hairy calyx, small corolla, linear style beak and dimorphic s...
متن کاملEcological interpretations of the leaf anatomy of amphibious species of Aeschynomene L. (Leguminosae - Papilionoideae).
We present the leaf anatomy of seven amphibious species of Aeschynomene L. (Papilionoideae, Leguminosae), interpreting their structures and ecological functions, and also, providing information on which their taxonomy can be based, especially of morphologically similar species. We evaluated Aeschynomene americana, A. ciliata, A. evenia, A. denticulata, A. fluminensis, A. rudis and A. sensitiva....
