The Evolution and Development of Nectar Spurs
… called a gibba, was compared to the common toadflax Linaria vulgaris, a related species within the Antirrhineae which possesses a spur. The comparison between a species with a gibba and a species which possesses a spur allows insights into nectar spur development. A morphological framework …

The Evolution and Development of Nectar Spurs
… understanding of nectar spur development in the toadflax genus *Linaria* (Plantaginaceae) – a sister taxon to the well-studied but spurless snapdragon genus *Antirrhinum*. Candidate genes hypothesised to play a role in spur initiation were selected based on a literature review and the results of …

Role of KNOX genes in the evolution and development of floral nectar spurs
A key question in biology is how changes in gene function or regulation produce new morphologies during evolution. The nectar spur is an evolutionarily labile structure known to influence speciation in a broad range of angiosperm taxa. Here, the genetic basis of nectar spur development, and the …
