Crocus sativus is a triploid sterile plant characterized by its long red stigmas, which produce and store significant quantities of carotenoid derivatives formed from the oxidative cleavage of beta-carotene and zeaxanthin. The present study reports on the genomic structures of two lycopene-beta-cyclase genes, CstLcyB1 and CstLcyB2a, and on their transcription patterns in different C. sativus ti...

In this study; the two Crocus L. taxa endemic to Bolu province, abantensis T. Baytop et Mathew and Crocus× paulineae Pasche & Kerndorff (hybrid) together with C. ancyrensis (Herbert) Maw subsp. ancyrensis, olivieri J.Gay, were used reveal their detailed leaf anatomical features. view of these characteristics, it was aimed determine true parents hybrid possible other distributed in south-sou...

background and objectives: angiogenesis is essential for tumor survival. inhibiting angiogenesis could be a mechanism for hindering tumor development. numerous studies have now been focused on agiogenesis inhibitors and many of such studies have targeted plant materials. in the present study, crocus pallasii subsp. haussknechtii has been evaluated for anti-angiogenesis properties. methods: anti...

fifteen microsatellite markers were employed to evaluate genetic relationships among different iranian species of crocus spp. (c. sativus, c. haussknechtii, c. cancellatus, c. speciosus, and c. caspius) from ten geographical regions (ghaen, gonabad, estahban, ferdows, veresk, reno, ali abad, kali abad, neka, and eslam abad). of these, 12 primers revealed polymorphism among crocus spp. average p...

Background and objectives: The goal of this study was to compare the cytotoxic and antioxidant activities of the corms extracts of two Crocus species (C. sativus L. and C. pallasii subsp. haussknechtii). Methods: n-Hexan, chloroform and methanol extracts of the corms were prepared. Cytotoxic activities of the extract...

Most flowers display distinct colour patterns comprising two different areas. The peripheral large-area component of floral colour patterns attracts flower visitors from some distance and the central small-area component guides flower visitors towards landing sites. Whereas the peripheral colour is largely variable among species, the central colour, produced mostly by anthers and pollen or poll...
