Abstract

The editorial in Frontiers in Genetics discusses comparative and evolutionary analyses of organelle genomes, focusing on studies of chloroplast and mitochondrial genomes in non-model species. The paper highlights genomic rearrangements and gene evolution in parasitic plants like Love Vines and the impact of a parasitic lifestyle on chloroplast genomes. Additionally, the editorial covers the sequencing of the mitochondrial genome of the Asian freshwater fish Osteochilus salsburyi and the evolution of the CHS gene in plants. Lastly, it explores population genetics in rats, specifically the Brown Rat and Oriental Rat, to understand genetic diversity and migration patterns. The research topic provides insights into the potential of organelle genome analyses for scientific studies and highlights the importance of new sequencing technologies for future research.

22. Dendrophthora kuijtiana(Santalaceae: Visceae), a new species and additions to the genus in Venezuela

Author

Canelón, Daniela S., Niño, Santos M., Dorr, Laurence J., and Caraballo-Ortiz, Marcos A.

Abstract

Dendrophthora kuijtiana(Santalaceae), a new species of mistletoe endemic to the páramos and subpáramos of the Venezuelan Andes, is described and illustrated. We discuss aspects of its ecology, and taxonomic affinities with Dendrophthora davidsei. In addition, we report a new record (D. paucifolia) and two updates (D. karuaianay D. warmingii) to Dendrophthorain Venezuela and present a dichotomous key to identify the species of Dendrophthorareported for the Guaramacal National Park.

Abstract

The impact of introduced species on native organisms is one of the main conservation concerns around the world. To fully understand the effect of introduced pollinators on native plants, it is important to know the reproductive biology of the focal species, especially its pollination biology. In this study we examined the breeding system of the endangered tree Goetzea elegans (Solanaceae), and compared pollination effectiveness of the two main floral visitors, Coereba flaveola (an avian nectarivore), and Apis mellifera (the introduced European Honeybee). We assessed the breeding system of G. elegans by applying several pollination treatments to flowers of cultivated trees to test fruit set, seed set, and seed viability. We also examined the pollination efficiency of A. mellifera and C. flaveola , and compared all the treatments with positive and negative controls. Our results indicate that the introduced honeybee A. mellifera is as efficient as the native bird C. flaveola in pollinating the flowers of G. elegans. This study also showed that G. elegans requires cross–pollination for fruit and seed set, and to obtain high seed viability rates. Despite the fact that many studies report exotic species as detrimental for native organisms, we document a case where an introduced insect has a beneficial impact on the reproductive biology of an endangered tropical tree.
