Investigation of pollen, seed, fruit morphology and antimicrobiyal and anti-biyofilm activity of some Alyssum L. species in Anatolian flora

The species of Alyssum L. which is also known as "kevke" or "kuduz otu" in Anatolia belongs to the family of Brassicaceae. Primarily, this species is distributed to the rocky and arid regions of the continents including North Africa, America, Asia and Europe. The most diverse region for the species of Alyssum L. is Eastern Mediterranean. In this research;pollen, seed, fruit morphologies and anti-bacterial and anti-biofilm activities and taxa of A. murale, A. callichroum, A. discolor, A. ochroleucum, A. sibiricum, A. strictum, A. strigosum, A. pateri subsp. Prostratum, A. baumgartnerianum, A. simplex and A. caricum of the species of Alyssum L. of the genus Brassicaceae were investigated. Samples of these taxa were collected in the field studies between the years of 2014-2017 that conducted in various regions of Turkey. In this research, the pollen morphology of 7 taxa, seed morphology of 9 taxa, fruit morphology of 10 taxa and anti-bacterial and anti-biofilm activity of 2 taxa were studied. As a result; the studies have shown that Alyssum pateri has the smallest pollen, Alyssum sibiricum has the shortest seed length, and the thickest seed witdh belongs to Alyssum ochorelucum and Alyssum callichroum is the smallest fruit. Besides, Alyssum caricum provides the best results on bacteria according to disc diffusion method and in antioxidant studies Alyssum sibiricum showed the best results.
