Abstract

Apocarotenoids are oxidative cleavage products of carotenoids. These molecules play vital physiological and developmental roles in plants. Besides this, apocarotenoids also hold tremendous pharmacological importance. Apocarotenoids are ubiquitously found across plant kingdom, but Crocus sativus (saffron) is the only source of some unique and economically important apocarotenoids. These apocarotenoids include crocin, picrocrocin, and safranal which besides having pharmacological importance are also responsible for the color, flavor, and aroma of the world’s costliest spice (saffron). Apocarotenoid biosynthesis in C. sativus is regulated throughout the life cycle with active changes in apocarotenoid composition of stigma due to developmental stage-specific requirements and in response to external environmental cues. Although the biosynthesis of these unique C. sativus apocarotenoids has been elucidated to a greater extent, there are still some missing links in the pathway. Besides, only a few studies have been carried out on the regulation, tissue- and developmental-specific accumulation, and transport of apocarotenoids in C. sativus as well as in other plants. The present review is an organized attempt to gain insights about the biosynthesis, regulation, and transport of apocarotenoids in C. sativus.
