Shang Fa Yang ( _zh. 楊祥發;
1932 -February 12 ,2007 ) was an acclaimed plant scientist and a professor at theUniversity of California, Davis .Birth and education
Shang Fa Yang was born in 1932 in Taiwan. He earned his bachelor's and master's degrees in agricultural chemistry at the
National Taiwan University . After completing his master's degree, he went to theUnited States and completed his doctoral degree in plant biochemistry fromUtah State University .Academic career
After completing his PhD, he conducted postdoctoral research at the
University of California, Davis , New York Medical School andUniversity of California, San Diego . After completing his postdoctoral research, he joined the facultyUniversity of California, Davis in 1966.Research
Shang Fa Yang was known for his research which unlocked the key to prolonging freshness in fruits and flowers. His research focused on how plants produce
ethylene , which is important in regulating a host of plant functions, ranging from seed germination to fruit ripening. He studied the pathway of ethylene biosynthesis and proved unequivocally the central role of methionine as a precursor of ethylene. Ethylene represents one of the five major hormones affecting plant development and maturation.He was the first scientist to report S-adenosylmethionine as an intermediate in methionine conversion to ethylene. Then, in 1979, he discovered aminocylopropane-1-carboxylic acid (ACC) as an intermediate. His discovery of ACC-synthase opened the way to the understanding of the regulating process of ethylene biosynthesis.
Awards and honours
Shang Fa Yang received several awards and honours for his research. In 1990, he was inducted into the U.S. National Academy of Sciences. In 1991, he was awarded the
Wolf Prize in Agriculture "for his remarkable contributions to the understanding of the mechanism of biosynthesis, mode of action and applications of the plant hormone, Ethylene."

Shang Fa Yang died on February 12, 2007 in a Davis hospital from complications of pneumonia.
