Scientists from Purdue University and the Chinese Academy of Sciences report the use of CRISPR/Cas9 to develop a variety of rice producing 25–31% more grain than traditional breeding methods.
The team, led by Jian-Kang Zhu, a distinguished professor in the Department of Horticulture and Landscape Architecture at Purdue and director of the Shanghai Center for Plant Stress Biology at the Chinese Academy of Sciences, made mutations to 13 genes associated with the plant hormone abscisic acid – known to play roles in plant stress tolerance and suppression of growth. Of several varieties created, one produced a plant that had little change in stress tolerance but produced 25% more grain in a field test in Shanghai, China, and 31% more in a field test conducted on China’s Hainan Island.
