Transgenic tall fescue containing the Agrobacterium tumefaciens ipt gene shows enhanced cold tolerance.
Embryogenic calli of Festuca arundinacea were transformed with the Agrobacterium tumefaciens isopentenyl transferase (ipt) gene driven by a maize ubiquitin promoter. Tillering ability, levels of chlorophyll a and b, and cold tolerance were greatly increased in the transgenic turfgrass, which resulted in the plants remaining more vigorous and staying green longer under lower temperatures.
