A genetic study on subtropical Anadenanthera colubrina (Vell.) Brenan var. cebil (Griseb.) Altschul tree from Northwestern Argentina
2017
Anadenanthera colubrina (Vell.) Brenan var. cebil (Griseb.) Altschul is a tree species in South America important for its cultural, economic, and medicinal uses. In addition, it represents a trace in memory of the forests that have decreased over the years and for this reason it is not only interesting to study but also important to preserve the tree species for future generations. In this paper, we have characterized the genetic diversity of four populations. We collected seeds from four different sites: San Bernardo (B), El Cebilar (C), Metán (M), and El Gallinato (G) in Salta Province, North Argentina. We then compared the intergenic transcribed sequences of ribosomal DNA, a known geneti…
The seed endosphere of Anadenanthera colubrina is inhabited by a complex microbiota, including Methylobacterium spp. and Staphylococcus spp. with pot…

Background and aims: Plant seeds are emerging micro–habitats, whose importance as reservoir and vector of beneficial microbes just begins to be recognized. Here we aimed to characterize the bacterial microbiota of the Anadenanthera colubrina seed endosphere, with special focus to beneficial traits and to the colonization pattern. Methods: Cultivation–dependent (isolation from surface–sterilized seeds) and cultivation–independent (pyrosequencing of 16S rRNA gene from metagenomic seed DNA) analyses, functional tests and microscopical investigations (fluorescence in situ hybridization coupled with confocal laser scanning microscopy (FISH-CLSM) were performed. Results: We isolated several Methy…
Plant bugs of the tribe Bothriomirini (Hemiptera: Heteroptera: Miridae: Cylapinae) from the Oriental Region: descriptions of eight new species and ke…
2012
Eight new species of the tribe Bothriomirini are described from the Oriental Region, namely Dashymenia cognata sp. nov., Dashymenia colubrina sp. nov., Dashymenia conspersa sp. nov., Dashymenia tenmalai sp. nov., Dashymenia webbi sp. nov., Dashymeniella spatulatiformis sp. nov., Dashymeniella ulu sp. nov., and Dashymeniella viklundi sp. nov. Five species are redescribed: Bothriomiris dissimulans (Walker), B. lugubris Poppius, B. testaceus Distant, Dashymenia croesus (Distant), and Dashymenia remus (Distant). Illustrations of the male genitalia, a color dorsal habitus photograph of the adult of most species, scanning electron micrographs of selected structures of Bothriomiris dissimulans, Da…
