Impact of dysploidy and polyploidy on the diversification of high mountain Artemisia (Asteraceae) and allies

Impact of dysploidy and polyploidy on the diversification of high mountain Artemisia (Asteraceae) and allies

Mas de Xaxars G, Garnatje T, Pellicer J, Siljak-Yakovlev S, Vallès J, Garcia S. Alpine Botany, in press. Molecular cytogenetics and the study of genome size have been used to understand evolutionary and systematic relationships in many species. However, this approach has seldom been applied to alpine plants. A group of dysploid–polyploid high mountain Artemisia […]

International Conference on Polyploidy, Hybridization and Biodiversity

International Conference on Polyploidy, Hybridization and Biodiversity

11-14 May 2016, Rovinj, Croatia This conference presents cutting edge research into the importance of polyploidy in genetics, evolution and ecology. It will be distinctive in its small group dynamics, wonderful location and great speakers. There will be three core sessions over two and a half days; these are: (1) the long-term and (2) immediate […]

The striking and unexpected cytogenetic diversity of genus Tanacetum L. (Asteraceae): a cytometric and fluorescent in situ hybridisation study of Iranian taxa

  See our latest article on Tanacetum cytogenetics and genome sizes! Background Although karyologically well studied, the genus Tanacetum (Asteraceae) is poorly known from the perspective of molecular cytogenetics. The prevalence of polyploidy, including odd ploidy warranted an extensive cytogenetic study. We studied several species native to Iran, one of the most important centres of […]

Scientific session commemorating the 50th anniversary of the death of Pius Font i Quer (1964-2014)

This year we commemorate the 50th anniversary of Pius Font i Quer’s death. He is an important and beloved botanist in our country, and many acts are being performed these days to praise his figure. One of them is the Scientific session that will be held next Tuesday 2nd December in the Institut d’Estudis Catalans, […]

Key Processes for Cheirolophus (Asteraceae) Diversification on Oceanic Islands Inferred from AFLP Data

Key Processes for Cheirolophus (Asteraceae) Diversification on Oceanic Islands Inferred from AFLP Data

We have the pleasure to present the publication of a recent paper from our team of the GSAD database. Congratulations to the authors! Again, it is a new outcome of research in genus Cheirolophus which has been studied from the genome size perspective in the past. Now it is the turn of AFLP data. Read […]

Patterns of chromosomal variation in natural populations of the neoallotetraploid Tragopogon mirus (Asteraceae)

Patterns of chromosomal variation in natural populations of the neoallotetraploid Tragopogon mirus (Asteraceae)

Chester, M., Riley, R. K., Soltis, P. S., & Soltis, D. E. (2014). Patterns of chromosomal variation in natural populations of the neoallotetraploid Tragopogon mirus (Asteraceae). Heredity. In this study authors assess chromosomal composition in a natural neoallotetraploid, Tragopogon mirus, and compare it with T. miscellus, which is an allotetraploid of similar age (~40 generations old).

The explosive radiation of Cheirolophus (Asteraceae, Cardueae) in Macaronesia

A new paper coauthored by several members of the GSAD database team has been recently released. Cheirolophus is an Asteraceae genus of which abundant genome size data can be found in this database. We invite you to have a look to this interesting and highly accessed paper! Abstract: Background Considered a biodiversity hotspot, the Canary […]

Slicing the wheat genome

Slicing the wheat genome

Science’s Special Issue on Slicing the wheat genome celebrates the 100th anniversary of the birth of Norman Borlaug, the Nobel Prize-winning plant geneticist who, through his contribution to the “green revolution,” reminds us of the importance of applying scientific knowledge to develop crop varieties. This is even more important today as we face a rapidly expanding […]
