high-velocity microprojectile-mediated gene transfer
Delivery StrategyHigh-velocity microprojectile-mediated gene transfer, or particle bombardment, is a physical DNA delivery harness used to establish a rapid transient expression assay. In the cited 1989 study, it introduced an oat phy-CAT reporter construct into rice, enabling analysis of phytochrome-regulated phy gene expression within less than 24 hours after bombardment.
