Engineering of genetic sterility in transgenically modified trees destined for commercial uses will simplify compliance with regulatory guidelines and mitigate ecological concerns of transgene dispersal. It could also be a critical technology for reducing the rate of escape and invasive mobility of exotic plantation species. Added benefits may include increased biomass production by redirecting energy normally expended on reproduction, and elimination of nuisance pollen and fruits. We discuss the two basic strategies for genetically engineering reproductive sterility; 1) suppression of reproductive gene expression and 2) genetic cell ablation of floral structures through the use of cytotoxins or gene products whose overexpression is detrimental to cell function. We also discuss various cytotoxins and inhibitors thereof that could be used to reverse sterility and enable traditional breeding.
