enlarge the volume of exploited soil, and aid in anchoring the plant to the soil. Their formation occurs as a series of developmental processes starting with cell fate specification in the meristem. The root-hair-forming epidermal
apex. Root hair elongation is characterized by a strong polarisation of the cytoskeleton, active cell wall modifications and dynamic ion movements. Finally, we discuss the functional and genetic similarities between the root hairs of angiosperms and the rhizoids of bryophytes and ferns. Author informat...
are encoded by Ca2+ channels and transporters and are decoded by a variety of Ca2+-binding proteins often called Ca2+ sensors, in which calcineurin B-like protein (CBL) proteins function by interacting with and activating a group of kinases and activate CBL-interacting protein kinases (CIPKs)....
development of root system: the cell division at the primary root (PR) meristem to add new cells enabling root growth; the generation of lateral roots (LR) to increase the exploratory capacity of the root system; the enlargement of the total surface of PR and LRs through root-hair growth ...
Root Hairs (RHs) growth is influenced by endogenous and by external environmental signals that coordinately regulate its final cell size. We have recently determined that RH growth was unexpectedly boosted when Arabidopsis thaliana seedlings are cultivat
Root hairs develop two layers of cell walls. The thin α-layer at the root hair tip can be expanded and formed by turgor pressure, while the thick β-layer at the non-growing tubular parts of the root hair provides stability and strength19. Hence, the synthesis of cell wall ...
It is thought to encode proteins that function more efficiently on cell wall modification during root hair morphogenesis (Won et al., 2010). OsEXPA17 expresses in root hair cells. OsexpA17 contains a point mutation, causing a change in the amino acid sequence. The mutant has short root ...
Mutants with defects in auxin activity fail to initiate roots and ex- hibit premature arrest of the root meristem and root stem cell function (Hardtke and Berleth, 1998). Exoge- nously applied auxin may have posi- tive or negative effects on root growth depending on the concentration; the ...
