INTRODUCTIONThis protocol describes general strategies for propagating Antirrhinum (snapdragon) species: self- and cross-pollination, cuttings, and grafting. Antirrhinum majus cultivars and some wild species are self-fertile, but they require self-pollination for high seed yields. Although self-fertile, A.

INTRODUCTIONIn this protocol, we describe methods for cultivating Antirrhinum (snapdragon) species. These plants are easily grown, provided that they have sufficient light and are not overwatered. In good conditions, most species will flower and produce seeds within 3-4 mo.

INTRODUCTIONThe Antirrhinum species group comprises approximately 20 morphologically diverse members that are able to form fertile hybrids. It includes the cultivated snapdragon Antirrhinum majus, which has been used as a model for biochemical and developmental genetics for more than 75 yr. The research infrastructure for A.

To understand the constraints on biological diversity, we analyzed how selection and development interact to control the evolution of inflorescences, the branching structures that bear flowers. We show that a single developmental model accounts for the restricted range of inflorescence types observed in nature and that this model is supported by molecular genetic studies. The model predicts associations between inflorescence architecture, climate, and life history, which we validated empirically.

We present an empirical model of Arabidopsis (Arabidopsis thaliana), intended as a framework for quantitative understanding of plant development. The model simulates and realistically visualizes development of aerial parts of the plant from seedling to maturity. It integrates thousands of measurements, taken from several plants at frequent time intervals.
