Pollination ecology of Swartzia apetala Raddi var. apetala (leguminosae-papilionoideae)

DNA microsatellite markers for Swartzia glazioviana (Fabaceae), a threatened species from the Brazilian Atlantic Forest.

PREMISE OF THE STUDY Development and characterization of a set of DNA microsatellite markers for Swartzia glazioviana (Fabaceae), a naturally rare and threatened tree species, were carried out to investigate its conservation genetics. METHODS AND RESULTS Through an enriched genomic library procedure, 10 DNA microsatellite loci were isolated and characterized for the species. The mean expected...

Function of the apetala-1 gene during Arabidopsis floral development.

We have characterized the floral phenotypes produced by the recessive homeotic apetala 1-1 (ap1-1) mutation in Arabidopsis. Plants homozygous for this mutation display a homeotic conversion of sepsis into brachts and the concomitant formation of floral buds in the axil of each transformed sepal. In addition, these flowers lack petals. We show that the loss of petal phenotype is due to the failu...

Invasive Capacity of the Mangrove Sonneratia Apetala in Hainan Island, China

XIN K, ZHOU Q, ARNDT SK & YANG X. 2013. Invasive capacity of the mangrove Sonneratia apetala in Hainan Island, China. The mangrove Sonneratia apetala has been introduced into China since 1985 as a plantation species in coastal area. There has been long time speculation regarding the invasive capacity of this species and its contribution to the degradation of native plant communities. In this st...

Morphological 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...
