How does a developing plant shoot know how, where, and when to grow? Dividing cells need to pass messages from one another to coordinate growth. In plants, important messages are packaged into RNA, which are sent from cell to cell. By studying the mustard-like plant Arabidopsis thaliana, Cold Spring Harbor Laboratory (CSHL) Professor David Jackson and his team found that RNA messages need a special protein to escort them where they need to go. Without this escort, cells cannot coordinate and the plant fails to develop properly.
