【 摘 要 】

Androgenesis is a phenomenon in which pollen grain changes its developmental pathway giving rise to haploid sporophyte. This alternative ontogenetic process is still not completely understood despite of its potencial to basic and applied studies, including crop improvement. The present article has the purpose of reviewing the factors related to the deviation of normal gametophytic route and the fundamental mechanisms of pollen embryogenesis induction.
