Reproductive structures of Nymphaea caerulea (blue water lily) - Sebastiano Nigris - Torrey Talks

MADS-box genes encode transcription factors which are involved in the control of many developmental processes in all green plants. In flowering plants, these genes play a role in root, flower, and fruit development. In some model species of flowering plants (such as Arabidopsis thaliana), the MADS-box genes responsible for correct floral organ initiation have been extensively studied, and a model of flower development has been described. However, this process is not the same across all angiosperms, and is understudied in many other groups. Nymphaea caerulea (blue water lily) is an early-diverging angiosperm which can be used as a model plant to study the involvement of MADS-box genes in this group of plants, and to further understand the genetic control of development in angiosperms, and the evolution of flowering plants. In this talk, we will explore the role of MADS-box genes in flower and fruit development of N. caerulea, as well as the unique seed dispersal mechanisms which the plant possesses.
