Aquilegia coerulea cultivar:Origami Transcriptome or Gene expression
By enforcing specific pollinator interactions, Aquilegia petal nectar spurs maintain reproductive isolation between species. Spur development is the result of three-dimensional elaboration from a comparatively two-dimensional primordium. Initiated by localized, oriented cell divisions surrounding the incipient nectary, this process creates a pouch that is extended by anisotropic cell elongation. We sought to understand the developmental basis of this 3D emergence from 2D primordial.
