Biotechnology: A hold on plant meiosis
Peter J. van Dijk1
Abstract
The process of meiosis involves genetic shuffling that dilutes the desirable traits of sexually reproducing crops. Identification of a mutation in which shuffling does not occur is a step forward for plant breeders.
Some plants can reproduce clonally through their seeds, resulting in offspring that are genetically identical to the mother plant. This unusual breeding system is called apomixis, and is known from more than 400 wild species, including dandelions, blackberries and various grasses.
