An expert has restarted breeding of a 2300-year-old ancient cypress, which is the only one of its kind in the world, in Jiange County, Guangyuan City, southwest China's Sichuan province, scol.com.cn reported on Sept. 20.

Experts tried to carry out breeding of the 20-meter-high cypress in late 20th century, but failed. Their regeneration ability is weak due to old age and they get chopped down for their superior wood, so there is only one of them left in the world, according to experts.

Professor Wang Li at College of Life Sciences at Sichuan University restarted the breeding research this month by using cottage, seeding, and tissue culture.

Wang is unsure if the experiment will succeed, but he added that although the cypress was classified as a new species by taxonomists, she hopes a conclusion could be drawn through the research concerning the controversy over whether the cypress is a new species or merely a mutant of common ones.
