effects of yeast extract (ye) (0, 0.05, 0.1, 0.2, 0.5 and 1%) were investigated on rosmarinic acid (ra) accumulation and tyrosine aminotransferase (tat) gene expression in melissa officinalis seedlings at different time intervals (4 and 17 hours). based on the results, only ye concentrations of 0.05%, 0.1%, and 0.2%, for the 17-hour treatment, significantly stimulated ra biosynthesis pathway. a...

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...
