A dynamic network of polymers, the actin cytoskeleton, co-ordinates numerous fundamental cellular processes. In pollen tubes, organelle movements and cytoplasmic streaming, organization of the tip zone, vesicle trafficking, and tip growth have all been linked to actin-based function. Further, during the self-incompatibility response of Papaver rhoeas, destruction of the cytoskeleton is a primar...

(1) Neighbourhood experiments were used to compare the magnitudes of competitive effect and competitive response using all pairwise combinations of Papaver rhoeas, Triticum aestivum and Avena sativa as neighbour species, and these three species plus Chenopodium album as target species. (2) Over 79% of the variance in target weight was explained by a simple hyperbolic function of neighbour weigh...

BACKGROUND Studies of ethnobotanical usages in south-eastern Turkey are rare. To widen this field of knowledge, we conducted an ethnobotanical study in Midyat (Mardin Province), Turkey. METHODS The field study was completed during three years (2007-2010). Our aim was to document the ethnobotanical uses of local plants and to make an ethnobotanical inventory of uncommon plants using qualitativ...
