Fine-tuning quantitative agronomic traits by manipulating gene copy number in rice

Chihiro Nomura, Hiroyuki Kanzaki, Eiko Kanzaki, Motoki Shimizu, Kaori Oikawa, Hiroe Utsushi, Kazue Ito, Yusaku Sugimura, Ryohei Terauchi, Akira Abe

This study manipulates gene copy number in rice to fine-tune agronomic traits, showing that increasing OsMADS18 copies leads to longer leaf and culm lengths.
