Saffron, the stigma of Crocus sativus Linné (Iridaceae family), has been known to inhibit aggregation of β-amyloid, a nerve tissue protein. α-Synuclein (αS) is a 140-amino acid protein found abundantly in various regions of the brain. Its abnormal aggregation and accumulation in nerve tissue are said to cause neurodegenerative diseases such as Parkinson's disease, Lewy body dementia, and multiple-system atrophy. This study (part of this study was presented at the 137th Annual Meeting of the Pharmaceutical Society of Japan) examined the effects of saffron, its constituents (crocin-1, crocin-2, crocetin, and safranal), and crocetin structural analogs (hexadecanedioic acid, norbixin, and trans, trans-muconic acid) on αS aggregation, and αS fibril dissociation...

Studies have indicated that florivory and nectar robbing may reduce reproductive success of host plants. However, whether and how these effects might interact when plants are simultaneously attacked by both florivores and nectar robbers still needs further investigation. We used Iris bulleyana to detect the interactions among florivory, nectar robbing and pollination, and moreover, their effects on plant reproductive success. Field investigations and hand-pollination treatments were conducted on two experimental plots from a natural population, in which Experimental plot was protected from florivores and Control plot was not manipulated...

Crocus sativus belongs to Iridaceae family and is the only plant species which produces apocarotenoids like crocin, picrocrocin, and safranal in significant quantities. Besides their organoleptic properties, Crocus apocarotenoids have been found to possess remarkable pharmacological potential. Although apocarotenoid biosynthetic pathway has been worked out to a great degree, but the mechanism that regulates the tissue and developmental stage-specific production of Crocus apocarotenoids is not known. To identify the genes regulating apocarotenoid biosynthesis in Crocus, transcriptome wide identification of zinc-finger transcription factors was undertaken...
