Abstract

<abstract abstract-type="main" id="wdev193-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p id="wdev193-para-0001">The gynoecium is the female reproductive structure of flowering plants, and is the site of ovule and seed development. The gynoecium is critical for reproductive competence and for agricultural productivity in many crop plants. In this review we focus on molecular aspects of the development of the <italic>Arabidopsis thaliana</italic> gynoecium. We briefly introduce gynoecium structure and development and then focus on important research advances published within the last year. We highlight what has been learned recently with respect to: (1) the role of auxin in the differential development of the medial and lateral domains of the Arabidopsis gynoecium; (2) the interaction between cytokinin and auxin during gynoecial development; (3) the role of auxin in the termination of the floral meristem and in the transition of floral meristem to gynoecium; and (4) recent studies that suggest a degree of evolutionary conservation of auxin mechanisms during gynoecial development in other eudicots. <italic>WIREs Dev Biol</italic> 2015, 4:555–571. doi: 10.1002/wdev.193</p> <p>For further resources related to this article, please visit the <ext-link ext-link-type="uri" xlink:href="http://wires.wiley.com/remdoi.cgi?doi=10.1002/wdev.193" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">WIREs website</ext-link>.</p> </abstract>
