Abstract/Description: | Crocussativus,amonocottriploidspeciesbelonging totheIridaceaefamily,iscultivatedforitsredstigmaticlobesof the carpel that constitute saffron. Flower development has been extensively studied in different plants. Different floral developmental pathways have been deciphered in many plants. In Crocussativus,floweristhemostimportantpartandunderstanding the pathway underlying the flower development can pave the way for new avenues to improve its productivity and quality. The combination of class A genes (including APETALA1; CsAP1 and APETALA2; CsAP2), class B genes (including APETALA3; CsAP3 and PISTILLATA; CsPI) and class C genes (including AGAMOUS; CsAG) that are active in each whorl,determinestheidentityoftheorgansthatwilllaterdevelop in that whorl. CsAP3 is a class B homeotic gene which promotes petal and stamen formation and has a very important roleinflowerdevelopment.Italsoactivatesothergenesplaying pivotal role in flower development. It has been earlier reported that CsAP3 gene has direct role in activation of CsNAP gene whichpromotessenescenceinplants.Presentworkwasfocused on study of relative gene expression changes of CsAP3 and CsNAP gene during different stages of flower development. CsAP3 gene expression was found maximum during latepreanthesis stages of stigma development. Expression increases from stage5 tostage 6offlower development and then reduces again from stage 6 to stage 7. CsNAP gene had moderate expression during stage 3 to stage 4 transition and its expression increased abruptly from stage 6 to stage 7 of flower development. There is no direct concordance in the expression of CsAP3 and CsNAP gene expression in saffron. We may conclude that some other factor(s) may be responsible for initiation of CsNAP expression and CsAP3 gene may directly/indirectly be involved in regulating the factors responsible for CsNAP activation. |
