Hamelia patens JAQC. (Rubiaceae) is a medicinal bush widely distributed in tropical areas of the American continent. It is used in Mexican Traditional Medicine for the treatment of menstrual disorders, therefore suggesting that its chemical constituents may have some effect on myometrium contractility. Physiological effects might differ due to quantitative variations in the content of alkaloids...

Pentatricopeptide repeat (PPR) proteins are widespread in eukaryotes and in particular, include several hundred members in land plants. The majority of PPR proteins are localized in mitochondria and plastids, where they play a crucial role in various aspects of RNA metabolism at the post-transcriptional level in gene expression. However, many of their functions remain to be characterized. In co...

The following new species are described: Limnesia (Limnesia) elongata sp. nov., gledhilli Limnesia. pseudomaceripalpis scutata victoria Tubophorella paluma nov. and T. queenslandica szalayi K. Viets, 1955 is synonymized with L. patens 1935. first description given of the females babinda Cook, 1986 hopa 1986. Keys provided for genera Tubophorella. Many records family in Australia.

Primer registro de colibrí cola pinta (Tilmatura dupontii, Trochilidae) para la Reserva Biosfera Sierra Huautla, Morelos, México.En agosto 2005 observamos y fotografiamos un macho dupontii) que forrajeaba sobre flores del arbusto Hamelia patens (Rubiaceae). Esta observación representa el primer esta especie en sur México, ca. 50 km al sureste registros anteriores Morelos.

Background: Analyses of complete genomes and large collections of gene transcripts have shown that most, if not all seed plants have undergone one or more genome duplications in their evolutionary past. Results: In this study, based on a large collection of EST sequences, we provide evidence that the haploid moss Physcomitrella patens is a paleopolyploid as well. Based on the construction of li...

Studies of the anther transcriptome on non-model plants without a known genome are surprisingly scarce. RNA-Seq and digital gene expression (DGE) profiling provides a comprehensive approach to identify candidate genes contributing to developmental processes in non-model species. Here we built a transcriptome library of developing anthers of Hamelia patens and analyzed DGE profiles from each sta...
