Recent progress in genome-scale sequencing and comparative mapping raises new challenges in studies of genome rearrangements. Although the pairwise genome rearrangement problem is well-studied, algorithms for reconstructing rearrangement scenarios for multiple species are in great need. The previous approaches to multiple genome rearrangement problem were largely based on the breakpoint distanc...

Throughout the world DNA banks are used as storage repositories for genetic diversity of organisms ranging from plants to insects to mammals. Designed to preserve the genetic information for organisms of interest, these banks also indirectly preserve organisms' associated microbiomes, including fungi associated with plant tissues. Studies of fungal biodiversity lag far behind those of macroorga...

Bees require large amounts of pollen for their own reproduction. While several morphological flower traits are known to have evolved to protect plants against excessive pollen harvesting by bees, little is known on how selection to minimize pollen loss acts on the chemical composition of pollen. In this study, we traced the larval development of four solitary bee species, each specialized on a ...

Gyrodromella represents a subgenus of the osmiine bee genus Chelostoma (Megachilidae) containing eight species, which are confined to the Palaearctic region. Analysis of female pollen loads, field observations and literature data suggest that all C. (Gyrodromella) species are oligolectic harvesting pollen exclusively on flowers of Campanula and possibly also closely related Campanulaceae genera...

PREMISE OF THE STUDY Microsatellite markers were identified and characterized to study the genetic diversity and structure, conservation status, taxonomy, and biogeography of subspecific taxa and populations of Campanula pyramidalis (Campanulaceae). METHODS AND RESULTS Eleven microsatellite markers were developed from genomic libraries enriched for di- and trinucleotide repeats. A total of 80...
