Abstract: | Summary The study of the formation of pollen in plants has been the focus of extensive morphologic and cytologic observations. This
complex developmental process requires the coordinated activity of both gametophytic and sporophytic tissues. The events that
occur during microspore development represent a carefully orchestrated program of physiologic, biochemical, and genetic activities.
Genes expressed specifically in pollen or in sporophytic tissues that support pollen development have only recently been identified
and desribed. In the present paper we describe several genes expressed during pollen development in the important oil seed
speciesBrassica napus (oil seed rape/canola). The characterization of three gene families expressed during microspore development is reviewed which
provides a basis for comparison with other genes expressed during pollen maturation. The, potential value of these genes for
the development of novel plant breeding strategies and hybrid seed production is discussed.
