Anther-Specific Gene Expression in Brassica and Arabidopsis

Pollen, the male gametophyte of flowering plants, plays a vital role in sexual reproduction and hence seed set. Pollen grains are the haploid products of the meiotic divisions of the diploid microsporocytes, which reside in the anther (Fig. 2–1). This developmental process requires an intimate interaction between two generations: the diploid sporophyte including the microsporocytes and anther tissues and the gametophyte (Knox, 1984). More than 26 developmental characters of male reproductive development have now been described, although for only a limited range of taxa (Blackmore et al., 1987). The character states for Brassica campestris pollen development are presented in Figure 2–2, and Table 2–2 which is based on data collected by Knox (1987).
