Introduction The formation of gametes is a key step in the lifecycle of any sexually reproducing organism. In flowering plants, the egg and sperm cells develop within haploid gametophytes (Figure 1). The female gametophyte of Arabidopsis originates from a single haploid spore (Figure 1A) through three nuclear division ...
