Nectary development and Gene Expression in the Cleomaceae.

Nectary development is a key floral feature because of nectar’s impact on pollination.
Nectar glands are an evolutionarily innovation that have co-evolved with nectarivore insects, bats, and birds. Nectar enhances attraction and rewards for pollinators.  Floral nectary research has been conducted in many families(e.g.,Geraniaceae, Fabaceae, Orchidaceae, Solanaceae, and Brassicaceae). However, there has been no research on glands in the Cleomaceae, despite their diversity and conspicuous nature in many species.  Herein, our goal is to determine the key regulators driving nectary development in the Cleomaceae, specifically by asking whether there is conservation or deviation with Arabidopsis, and other important flowering families.We combine transcriptomic data with detailed developmental description of nectary gland development in two species of Cleomaceae: Cleome violacea and Polanisia dodecandra.  Both species have prominent nectaries and are found in different clades. We examined key genes necessary for nectary gland formation and found both convergence and divergence from model species
