1.  Distinct and Dynamic Auxin Activities During Reproductive Development 
Flowering plants have evolved sophisticated and complicated reproductive structures to ensure optimal conditions for the next generation. Successful reproduction relies on careful timing and coordination of tissue development, which requires constant communication between these tissues. Work on flower and fruit development over the last decade places the phytohormone auxin in a key role as a master of patterning and tissue specification of reproductive organs. Although many questions still remain, it is now clear that auxin mediates its function in flowers and fruits through an integrated process of biosynthesis, transport, and signaling, as well as interaction with other hormonal pathways. In addition, the knowledge obtained so far about auxin function already allows researchers to develop tools for crop improvement and precision agriculture.
The phytohormone auxin is master regulator of plant reproductive organs. It marks floral initiation sites and controls stamen, pollen, gynoecium, and fruit development.

3.  The role of auxin in style development and apical-basal patterning of the Arabidopsis thaliana gynoecium 
Plant Signaling & Behavior  2009;4(2):83-85.
In angiosperms, the gynoecium constitutes the female reproductive organ that after fertilization develops into a fruit and in Arabidopsis thaliana the gynoecium is formed by the congenital fusion of two carpels. In the last few years many genes involved in female organ development have been identified and there have been several reports on the involvement of the plant hormone auxin in gynoecium patterning. An auxin gradient has been suggested to establish the apical-basal patterning of the gynoecium and recently it has been shown that elevated apical auxin levels can compensate for the loss of several style-promoting factors but that auxin is dependent on their action in apical-basal patterning. Here we discuss the role of auxin and different upstream, downstream or parallel factors in the apical-basal patterning of the gynoecium. We focus specifically on the development of style and stigma and discuss the most recent findings.
