1·Basipetal differentiation is seen in the formation of proto-and metaxylem in the stem.
在茎原生木质部和次生木质部的形成过程中可以看到这种类型的分化。
2·Cytochalasin D experiments confirm that the movement of statoliths is actin-dependent and the actin filaments exert basipetal forces on statoliths in gravity field.
细胞松弛素D的实验证实平衡石的这种运动是和肌动蛋白丝相关，而且在重力场中作用于平衡石的向基力也是肌动蛋白丝产生的。
