Flowers of animal-pollinated plants are integrated structures shaped by the action of pollinator-mediated selection. It is widely assumed that pollination specialization increases the magnitude of floral integration. However, empirical evidence is still inconclusive. In this study, we explored the role of pollinator diversity in shaping the evolution of corolla-shape integration in Erysimum, a ...

Pollinator-mediated evolutionary divergence has seldom been explored in generalist clades because it is assumed that pollinators in those clades exert weak and conflicting selection. We investigate whether pollinators shape floral diversification in a pollination generalist plant genus, Erysimum. Species from this genus have flowers that appeal to broad assemblages of pollinators. Nevertheless,...

Glucosinolates from seed meals of Erysimum hieracifoliwn and l\1alcolmia mantlma were treated with thioglucosidase (EC 3.2.3.1). and the resultant aglucon products investigated. A major product from E. hieracifoliwll was 3-hydroxypropyl isothiocyanate from the novel precursor 3-hydroxypropylglucosinolate. Other aglucon products were 3-methylsulfonylpropyL 3-methylsulfinylpropyl. 3-methylthiopro...

Anal fissure is an ischemic ulcer that occurs in anoderm and it has no obvious etiology and pathophysiology in current medicine. Anal fissure has a profound history in Persian and Persian medicine and wallflower (Erysimum cheiri (L.) Crantz) has been a common medication in this case. Traditional oil and/or dilute decoction of wallflower has been introduced as an effective topical medic...

Background: To develop the high-performance thin layer chromatography (HPTLC) finger print profile of hydroalcoholic and ethylalcohol extracts seeds Tudri Surkh (Cheiranthus cheiri). Methods: Chromatographic technique was used for separation components from HPTLC carried out using CAMAG system equipped with Linomat V applicator, WinCATS software.Results: profiling extract confirm presence vario...

Paleontological and phylogenetic studies have shown that floral zygomorphy (bilateral symmetry) has evolved independently in several plant groups from actinomorphic (radially symmetric) ancestors as a consequence of strong selection exerted by specialized pollinators. Most studies focused on unraveling the developmental genetics of flower symmetry, but little is known about the adaptive signifi...
