Morphomechanical Innovation Drives Explosive Seed Dispersal
How mechanical and biological processes are coordinated across cells, tissues, and organs to produce complex traits is a key question in biology. Cardamine hirsuta, a relative of Arabidopsis thaliana, uses an explosive mechanism to disperse its seeds. We show that this trait evolved through morphomechanical innovations at different spatial scales. At the organ scale, tension within the fruit wa...
متن کاملImperfect replacement of native species by non-native species as pollinators of endemic Hawaiian plants.
Native plant species that have lost their mutualist partners may require non-native pollinators or seed dispersers to maintain reproduction. When natives are highly specialized, however, it appears doubtful that introduced generalists will partner effectively with them. We used visitation observations and pollination treatments (experimental manipulations of pollen transfer) to examine relation...
متن کاملEndozoochorous seed dispersal of plant species in semi-steppe rangelands
During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...

متن کاملBittercress WSSA09
Bittercress (Cardamine hirsuta) and mouse ear cress (Arabidopsis thaliana) both produce siliques that are morphologically similar to each other: a long cylindrical silique composed of two fused carpels. Despite this external similarity, the bittercress capsules have the ability to discharge their seed explosively, whereas the siliques of mouse ear cress only crack open along the suture lines to...
