摘要:Abstract(#br) Background(#br)Transitions between perennial and an annual life history occur often in plant lineages, but the genes that control whether a plant is an annual or perennial are largely unknown. To identify genes that confer differences between annuals and perennials ...

摘要:Abstract(#br)Continental-wide phylogeographic studies of plants in North America are rare. In our study we examined the phylogeographic history of Boechera (Brassicaceae) on a continental-wide scale testing if it is possible to do an analysis for 57 of the currently accepted taxa...

摘要:ABSTRACT(#br)The North American genus Boechera comprises according to current taxonomic classification 110 species. Most of them are centered in western North America, with some species extending from the west into eastern North America and seven exclusively occurring in eastern ...

摘要:Abstract(#br)The northern Chilean Atacama Desert is among those regions on Earth where life exists at its dry limits. There is almost zero rainfall in its core zone, and the only source of water is a spatio-temporally complex fog system along the Pacific coast, which is reaching ...

摘要:Abstract(#br)The genetic mechanisms causing seed development by gametophytic apomixis in plants are predominantly unknown. As apomixis is consistently associated with hybridity and polyploidy, these confounding factors may either (a) be the underlying mechanism for the expression...

摘要:Abstract(#br)In several studies we used the 5′- trn L(UAA)– trn F(GAA) region of the chloroplast DNA for phylogeographic reconstructions, gene diversity calculations and phylogenetic analyses among the genera Arabidopsis and Boechera . Despite the fact that extensive gene du...

摘要:Abstract(#br)Molecular DNA based data sets are the most important resource for phylogenetic reconstruction. Among the various marker systems, which were introduced and optimized within the last decade, coding sequences played an important role, especially when molecular clock app...

摘要:The circumscription of the genus Arabis underwent many and drastic changes within the past. Using DNA sequence information from the nuclear ribosomal RNA and parts of the plastid genome ( trn L‐ trn LF), as well as a critical evaluation of herbarium material from East Asia a...

摘要:• Premise of the study: The high mountains in southern Anatolia and the eastern Mediterranean are assumed to play a major role as a primary center of genetic diversity and species richness in Eurasia. We tested this hypothesis by focusing on the widespread perennial arctic‐a...
