Advance on the Study of Biotechnology in Zoysiagras

Some species in the genus Zoysia possess agronomically useful traits such as drought tolerance,salt tolerance and wear tolerance.Recent studies show that DNA transfer and recombination technology provides great potential for genetic improvement of zoysiagrasses;molecular linkage maps were constructed from Zoysia japonica and its hybrids with Zoysia matrella;the researches on gene cloning and gene resource are in progress.In this review,we summarized the current knowledge in the study of genetic transformation and gene resource in zoysiagrass,and pointed out some problems and prospects.
