WebCRC gene is essential for female development and plants lacking this will not produce pistils. So cells expressing this gene will give rise to female parts [ref]. Nonetheless mutation happening at any stage of the development of floral meristem can be transmitted to the pollens/ovules if the mutated cells stochastically give rise to that lineage.
