Stigma-like structures (SLS) were produced under in vitro conditions. Highest response was observed with half ovaries on G-5 media supplemented with different combinations of phytohormones. The relative quantification through real time PCR for expression of apocarotenoid genes like CsBCH and CsGT-2 revealed that there is increase in expression from callus to SLS development. Expression pattern of CsBCH and CsGT-2 studied in different flower parts revealed highest expression in stigma followed by SLS, style and tepal. Expression of the regulatory genes responsible for biosynthesis of apocarotenoids viz; crocin, picrocrocin and safranal is getting upregulated in SLS in saffron hence revealing that these structures are developmentally closely related to natural stigma.
