The ASYMMETRIC LEAVES2-LIKE/LATERAL ORGAN BOUNDARIES (LOB) DOMAIN (ASL/LBD) genes encode plant-specific nuclear proteins containing the conserved domain AS2/LOB. In this study, the function of a member of the Arabidopsis thaliana AS2/LOB gene family, ASL11/LBD15, was investigated. The results show that ASL11/LBD15 is expressed in the meristems of shoot apex, root apex, organ boundaries, and developing...
Cellular growth and movement require both the control of direction and the physical capacity to generate forces. In animal cells directional control and growth forces are generated by the polymerization of and traction between the elements of the cytoskeleton. Whether actual forces generated by the cytoskeleton play a role in plant cell growth is largely unknown as the interplay between turgor and...
The cell wall is one of the structural key players regulating pollen tube growth, since plant cell expansion depends on an interplay between intracellular driving forces and the controlled yielding of the cell wall. Pectin is the main cell wall component at the growing pollen tube apex. We therefore assessed its role in pollen tube growth and cytomechanics using the enzymes pectinase and pectin methyl...
