Endosomal Interactions during Root Hair Growth
The dynamic localization of endosomal compartments labeled with targeted fluorescent protein tags is routinely followed by time lapse fluorescence microscopy approaches and single particle tracking algorithms. In this way trajectories of individual endosomes can be mapped and linked to physiological processes as cell growth. However, other aspects of dynamic behavior including endosomal interac...
متن کاملRoot Hair Growth in Arabidopsis thaliana
We study the factors that affect the root hair growth in the Arabidopsis thaliana plant. From experimental data, we measure how the average velocities of growth and tip shapes of the root hairs are affected by pressure and nutrients. Then using a biomechanical model, we can compute the physical parameters of the root hair and aim to correlate our model with experiments by using image processing...
متن کاملNew ideas on root hair growth appear from the flanks.
P lant root hairs are experimental model systems for research on plant cell growth. The involvement of protons and reactive oxygen species (ROS) in root hair growth and development has been the subject of significant research effort (e.g., refs. 1–4). pH specifically has been implicated in the control of plant cell expansion (5), including that in root hair cells (6). ROS have recently come to ...
متن کاملRoot hair growth: it's a one way street
Over the last few decades, our understanding of directed cell growth in different organisms has substantially improved. Tip-growing cells in plants elongate rapidly via targeted deposition of cell wall and membrane material at the cell apex, and use turgor pressure as a driving force for expansion. This type of polar growth requires a high degree of coordination between a plethora of cellular a...
متن کاملRoles of phosphatidylinositol 3-kinase in root hair growth.
The root hair is a model system for understanding plant cell tip growth. As phosphatidylinositol 3-phosphate [PtdIns(3)P] has been shown in other plant cell types to regulate factors that affect root hair growth, including reactive oxygen species (ROS) levels, cytoskeleton, and endosomal movement, we hypothesized that PtdIns(3)P is also important for root hair elongation. The enzyme that genera...
