Evolution of the Selfing Syndrome in Arabis alpina (Brassicaceae)
INTRODUCTION The transition from cross-fertilisation (outcrossing) to self-fertilisation (selfing) frequently coincides with changes towards a floral morphology that optimises self-pollination, the selfing syndrome. Population genetic studies have reported the existence of both outcrossing and selfing populations in Arabis alpina (Brassicaceae), which is an emerging model species for studying t...
متن کاملComparative evolutionary analysis of chalcone synthase and alcohol dehydrogenase loci in Arabidopsis, Arabis, and related genera (Brassicaceae).
We analyzed sequence variation for chalcone synthase (Chs) and alcohol dehydrogenase (Adh) loci in 28 species in the genera Arabidopsis and Arabis and related taxa from tribe Arabideae. Chs was single-copy in nearly all taxa examined, while Adh duplications were found in several species. Phylogenies constructed from both loci confirmed that the closest relatives of Arabidopsis thaliana include ...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولPolyploidy and hybridization in Bulgarian Brassicaceae: distribution and evolutionary role
The results from the investigation and analysis of the chromosome numbers and ploidy levels of 141 species and not nominal subspecies of Brassicaceae, their distribution and phytogeographical relations are discussed. Nearly 65 % of the taxa are diploids, most of them perennials, Mediterranean, Anatolian and Pontic floristic elements. Another 35 % are polyploids, c. 2/3 of them with tetraploid c...
متن کاملSpecies distribution modelling of invasive alien species; Pterois miles for current distribution and future suitable habitats
The present study aims to predict the potential geographic distribution and future expansion of invasive alien lionfish (Pterois miles) with ecological niche modelling along the Mediterranean Sea. The primary data consisted of occurrence points of P. miles in the Mediterranean and marine climatic data layers were collected from global databases. All the used models run 100% su...
