Novel Embryological Study of Vanilla planifolia using Confocal Scanning Laser Microscopy.

Despite long-standing biological and evolutionary interest, Orchidaceae remain to be a widely under-investigated lineage. In particular, detailed studies of post-pollination ovule development regarding development of the female reproductive structures are lacking. Confocal scanning laser microscopy has been used successfully to examine ovule and female gametophyte development in one orchid and in Arabidopsis. Here, individual generative cells and the female gametophyte were imaged via confocal scanning laser microscopy. The results of this work will illuminate details of developing pre- and postmeiotic ovules in V.planifolia. Increasing knowledge of V. planifolia ovule development and its correlation with pollination will lead to a better understanding of how to develop improved and new vanilla varieties that offer enhanced flavor, are hardier, and more disease-resistant. This research will ultimately be used to benefit the smallholder vanilla farmers worldwide, most of whom are indigenous groups in food-insecure and impoverished developing regions.
