DnFCA Isoforms Cooperatively Regulate Temperature-Related Flowering in Dendrobium nobile.

ABSTRACT: Timely flowering is a determinative trait for many economically valuable species in the Dendrobium genus of the Orchidaceae family, some of which are used for ornamental and medicinal purposes. D. nobile, a representative species of nobile-type Dendrobium, normally flowers in spring after exposure to sufficient low temperatures in winter. However, flowering can be stopped or disrupted by the untimely application of high temperatures. Little is known about the regulation and the mechanisms behind this switch. In this study, we report two isoforms from the KFK09_017173 locus of the D. nobile genome, named DnFCAγ and DnFCAβ, respectively, that cooperatively regulate flowering in D. nobile. These two isoforms are generated by alternative 3' poly
