Sex Determination in Dioecious Rumex acetosa Delecia Utley ( and Janelle Burke ( Dept. of Biology, Howard University, 415 College St NW, Washington, DC 20059.

Dioecious plants are plants with male and female reproductive parts on different plants. Sex ratio in dioecious plants is an issue still being explored amongst botanist. The sex ratios in dioecious plant populations are often close to a 1:1 ratio, or are male biased due to gender-specific differences.  Rumex acetosa (Polygonaceae) is a dioecious wind-pollinated plant in which females posses XX, and males XY1Y2 sex chromosome system.  To resolve functional sex among R. acetosa plants, leaf material was analyzed, using a PCR-based technique involving RAY, a male-specific DNA marker, to determine the sex of the plants. The observed female bias sex-ratio is consistent with the view that the Rumex population shows female bias which has been shown in other studies. The results of the sex screening will be used to determine a nutrient treatment regimen to further study the sex ratio in Rumex acetosa.
