Gene flow between domesticated species and their wild relatives is receiving growing attention. This study addressed introgression between wheat and natural populations of its wild relatives (Aegilops species). The sampling included 472 individuals, collected from 32 Mediterranean populations of three widespread Aegilops species (Aegilops geniculata, Ae. neglecta and Ae. triuncialis) and compar...

Extensive gene flow between wheat (Triticum sp.) and several wild relatives of the genus Aegilops has recently been detected despite notoriously high levels of selfing in these species. Here, we assess and model the spread of wheat alleles into natural populations of the barbed goatgrass (Aegilops triuncialis), a wild wheat relative prevailing in the Mediterranean flora. Our sampling, based on ...

This paper presents new records and noteworthy data on the following taxa in SE Europe adjacent regions: parasitic fungus Antherospora hortensis, saprotrophic fungi Loweomyces fractipes Pholiota henningsii, stonewort Chara canescens, mosses Grimmia caespiticia Rhodobryum ontariense, fern Woodsia alpina, monocots Aegilops triuncialis, Epipactis purpurata, Galanthus elwesii Typha shuttleworthii d...

It is important to predict which invasive species will benefit from future changes in climate, and thereby identify those invaders that need particular attention and prioritization of management efforts. Because establishment, persistence, and spread determine invasion success, this prediction requires detailed demographic information. Explicit study of the impact of pattern on demographic resp...

Homoeologous metaphase I (MI) associations in hybrids between durum wheat and its wild allotetraploid relatives Aegilops neglecta, Ae. triuncialis and Ae. ventricosa have been characterized by a genomic in situ hybridization procedure that allows simultaneous discrimination of A, B and wild species genomes. Earlier results in equivalent hybrids with the wild species Ae. cylindrica and Ae. genic...

the genus aegilops is one of the wheat relatives which comprise the main part of its gene pool.the identification of the aegilops species is difficult due to their vast morphological similarities and geneflow among different species of aegilops and cultivated wheat. some morphological characters are used todistinguish different species in aegilops. in this study, we evaluate all these character...

Polyploidy has been ubiquitous in plant evolution and is thought to be an important engine of biodiversity that facilitates speciation, adaptation, and range expansion. Polyploid species can exhibit higher ecological tolerance than their progenitor species. For allotetraploid species, this higher tolerance is often attributed to the existence of heterosis resulting from entire genome duplicatio...
