{Reference Type}: Journal Article {Title}: Bending during seedling emergence: Mechanochemical insight. {Author}: Bai B; {Journal}: Trends Plant Sci {Volume}: 26 {Issue}: 9 {Year}: 09 2021 {Factor}: 22.012 {DOI}: 10.1016/j.tplants.2021.06.007 {Abstract}: The apical hook is a crucial structure during seedling development in dicotyledonous plants. It protects the fragile shoot meristem during its journey toward the surface from constraints imposed by the surrounding soil, which safeguards seedling emergence. Emerging evidence sheds light on the regulation of hook development through mechanochemical constraints.
