摘要
In contrast to primary roots,lateral roots partially repress gravitropic growth and establish a distinct gravitropic set point angle(GSA;Digby and Firn 1995).The distinct GSAs of primary and lateral roots ultimately allow the root system to radially explore its surroundings(Mullen and Hangarter 2003).Lateral roots emerge in a 90°angle from the primary root(so-called stage I;Figure 1).
