Abstract

An alfalfa probe identical at 85% to a hydroxyproline rich glycoprotein of bean, hybridizes with RNAs of Mercurialis annua L. Five poly (A+) RNAs are expressed in pistillate flowers (3600, 2500, 2000, 1500, 950) and one in staminate flowers (1330). These RNAs are encoded by one gene of Mercurialis. Female RNAs are induced in feminized males by cytokinins as soon as the first day of feminizing treatment for the RNA 3600, whereas the male RNA 1330, progressively disappears. The hypothesis of a differential regulation of splicings, linked to cytokinins in each sex is proposed. If confirmed, plant sexes would be explained in a way parallel to those demonstrated in Drosophila.
