| Research Abstract |
Rapid and efficient in vitro culture system and novel methods for particle bombardment and Agrobacterium-mediated transformation using mature embryos as explants have been established in zoysiagrass (Zoysia japonica). Fructsyltransferase gene from timothy (PpFT1) involving a synthesis of highly polymerized fructan contributed to increase freezing tolerance by accumulation of fructan and glucose in cold acclimated plants. CBF gene (LpCBFIVa) from perennial ryegrass functioned with an increase of freezing tolerance with delaying flower time.
