Video – Reproductive development in Cucumis – Floral sex expression and fruit development, Rebecca Grumet, professor, Department of Horticulture, Michigan State University. Cornell University Department of Horticulture seminar series, Sept. 19, 2011
Summary: The Cucurbitaceae family, including cucumbers, melons, squashes and pumpkins, is marked by extreme sexual plasticity and variation in fruit growth and morphology. We are using molecular genetic and transcriptomic approaches to study factors underlying sex determination and fruit development in melons (Cucumis melo) and cucumbers (C. sativus). We are particularly interested in understanding the role of ethylene production, perception, and signaling in regulation of unisexual flower development. Our questions regarding fruit development focus on early stages of fruit growth and factors influencing fruit size, shape, and resistance to infection by Phytophtora capcisi.
