Background. The investigation of the genetic nature of plant phenotypic variability is of great importance for understanding biological diversity, distribution and adaptation of plants to environmental conditions. The aim of our work was to study the genetic differentiation of two phenotypes of Plantago media in South Timan. Materials and methods. The genetic differentiation of light and shadow phenotypes of Plantago media plants was evaluated using intersimple sequence repeats (ISSR) markers. Results. The population-genetic analysis of 210 loci revealed two clusters, which boundaries coincided with the boundaries between plants of light and shadow phenotypes. The results of the discriminatory analysis of the main components and AMOVA (FST = 0.07, p = 0.001) confirmed that there are statistically significant genetic differences between these phenotypes even though they possess a high genetic similarity. Conclusion. Light and shadow Plantago media phenotypes adapted to different ecological conditions are genetically differentiated. The population genetic analysis using ISSR markers is a sensitive tool for identifying the genetic diversity of phenotypic plant variations formed under the influence of environmental factors.

Abstract NF-κB and IκB proteins have central roles in regulation of inflammation and innate immunity in mammals. Homologues of these proteins also play an important role in regulation of the Drosophila immune response. Here we present a molecular population genetic analysis of Relish, a Drosophila NF-κB/IκB protein, in Drosophila simulans and D. melanogaster. We find strong evidence for adaptive protein evolution in D. simulans, but not in D. melanogaster. The adaptive evolution appears to be restricted to the IκB domain. A possible explanation for these results is that Relish is a site of evolutionary conflict between flies and their microbial pathogens.

Rhodnius ecuadoriensis Lent & León (Hemiptera: Reduviidae) es el prinicipal vector de    la enfermedad de Chagas en Ecuador, donde la estructura genética de sus poblaciones es poco conocida. Nosotros probamos seis Repeticiones Cortas en Tamdem (RCT) de R. pallescens Barber en poblaciones selváticas y domésticas de R. ecuadoriensis. Dos microsatelites fueron monomórficos, dos dieron resultados ambiguos y dos fueron polimórficos (16 y 19 alelos) y fueron utilizados para análisis. Los resultados de las frecuencias alélicas, AMOVA y los pruebas Bayesianas para genética favorecen la teorí­a de la existencia de una sola población. Estos resultados preliminares sugieren que las poblaciones selváticas y domésticas d R. ecuadoriensis intercambian frecuentemente migrantes. Por consiguiente el control de la Enfermedad de Chagas requiere vigilancia entomológica continua en la costa del Ecuador.
