From: Multi-species transcriptome analyses for the regulation of crocins biosynthesis in Crocus
Differential accumulation of crocins and accumulation in two developmental stages of stigmas from Crocus. a) Stigmas in stage I and stage II from C. sativus (i and ii), C. cartwrightianus (iii and iv), and C. ancyrensis (v and vi). b) The stigmas in stage II present a distinctive yellow colouration due to the accumulation of different apocarotenoids in this stage in all the Crocus species
