Genetic and epigenetic processes in seed development.

Seed development has emerged as an important area of research in plant development. Recent research has highlighted the divergent reproductive strategies of the male and female genomes and interaction between genetic and epigenetic control mechanisms. Isolation of genes involved in embryo and endosperm development is leading to an understanding of the regulation of these processes at the molecular level. A thorough grasp of these processes will not only illuminate an important area of plant development but will also have an impact on agronomy by helping to facilitate food production. An understanding of seed development is also likely to clarify the molecular mechanisms of apomixis, a fascinating process of asexual seed production present in many plants.
