Common ragweed ( Ambrosia artemisiifolia L.) is an annual Asteraceae species native to North America which highly invasive across Europe and has harmful impacts, especially on human health agriculture. Besides its wide ecological range, particularly high reproductive power by seeds promoting spread various habitats regions. To prevent further control the plant, European Commission funded projec...

Non-native forest tree species have been introduced in Europe since the 16th century, but only second half of 20th century significance seed source origin for their economic use was recognized, resulting establishment numerous provenance trials at a national, regional, European and International level, as those led by IUFRO. Breeding programs also launched continent most economically important ...

Tree species distributions associated with rainfall are among the most prominent patterns in tropical forests. Understanding the mechanisms shaping these patterns is important to project impacts of global climate change on tree distributions and diversity in the tropics. Beside direct effects of water availability, additional factors co-varying with rainfall have been hypothesized to play an im...

The morphologically diverse bodies of seed plants comprising gymnosperms and angiosperms, which separated some 350 Ma, grow by the activity of meristems containing stem cell niches. In the dicot model Arabidopsis thaliana, these are maintained by the stem cell-promoting functions of WUS and WUSCHEL-related homeobox 5 (WOX5) in the shoot and the root, respectively. Both genes are members of the ...
