Ectopic Expression of a Fagopyrum esculentum APETALA1 Ortholog only Rescues Sepal Development in Arabidopsis ap1 Mutant.

ABSTRACT: Fagopyrum esculentum (Polygonaceae: Caryophyllales) exhibits an undifferentiated perianth comprising five showy tepals, which does not completely correspond to the perianth differentiated into typical sepals and petals in most core eudicots. In Arabidopsis, the APETALA1 (AP1) gene is involved in specifying sepals and petals development. Here we isolated AP1 ortholog, FaesAP1, and a 2.2kb FaesAP1 promoter (pFaesAP1) from F. esculentum. FaesAP1 expression is mainly detectable in all floral organs and maintains at a high level when tepals elongate rapidly both in pin and thrum flowers. Moreover, the GUS reporter gene driven by pFaesAP1 was activated in flowers where the sepals were intense, but the petals very
