...Qiang Zhu; Marçal Gallemí; Jiří Pospíšil; Petra Žádníková; Miroslav Strnad; Eva Benková ABSTRACT The apical hook is a transiently formed structure that plays a protective role when the germinating seedling penetrates through the soil towards the surface. Crucial for proper bending is the local...

...Björn C. Willige; Eri Ogiso-Tanaka; Melina Zourelidou; Claus Schwechheimer When penetrating the soil during germination, dicotyledonous plants protect their shoot apical meristem through the formation of an apical hook. Apical hook formation is a dynamic process that can be subdivided into hook...

... mechanisms that lead to the initial installation of an auxin gradient are still poorly understood. In this study, we aimed to unravel the cross-talk between auxin and ethylene in the apical hook. Auxin measurements, the expression pattern of the auxin reporter DR5::GUS and the localization of auxin...
