Land plants lacking roots generally have uniseriate (one-cell-thick), filamentous rhizoids that assume a similar function. The first root to develop, in the embryo, is termed the radicle. If the radical continues to develop after embryo growth, it is known as the primary root. Additional ...
Conclusion The study of root hairs and the superficial cells from which they arise has attracted many workers, partly no doubt because of their absorptive function and partly because their superficial position and relatively simple structure make them convenient for the study of cell enlargement. The...
A root hair is composed of a single-cell that is developed as a tubular outgrowth of a root epidermal cell and expanded by polar growth (Campanoni and Blatt, 2007; Grierson et al., 2014). Root hairs perform multiple key functions in the plant growth and developmental process, notable among...
Explain and give examples of cellular transport such as osmosis, active transport, simple diffusion and facilitated diffusion. How do cells in the epidermis obtain nutrients and oxygen? What is the function of the hair cells in the organ of Corti?
focusing first on filamentous actin organization during root hair development and the response of root hairs to the rhizobial signal molecule Nod factor, which reveals the function of actin in root hair elongation. In addition, we discuss the role of actin binding proteins in organizing the actin...
OsAUX1promotes root hair growth at low external P levels.a9-day-old WT, osaux1-1;1andosaux1-1;3seedlings were grown for 6 days in hydroponics at three different P concentrations. Scale bar 1 mm.bQuantitation of RH length in WT, osaux1-1;1andosaux1-1;3mutants reveal low P. ...
Moving from the cell to the whole-organ level, we next asked if BL modulation of cell geometry is correlated with radial growth of the meristem. To address this question, radial growth of the different tissues along the meristem was quantified as a function of distance from the QC (as deter...
cell trajectory analysis was performed using PAGA implemented on Scanpy for both the original feature dataset and the dataset with only 110 genes, with default parameters. We used the enrichKEGG function in the clusterProfiler package (version 4.6.2) to perform functional enrichment analysis. We empl...
NO is also involved in root hairgrowth and development. The root epidermis is composed of two cell types: trichoblasts (or hair cells) and atrichoblasts (nonhair cells). InArabidopsis, as well as in lettuce, the NO scavenger cPTIO blocked the auxin-induced root hair elongation indicating tha...
3. something resembling or suggesting the root of a plant in position or function. 4. the embedded or basal portion of a hair, tooth, nail, nerve, etc. 5. the fundamental or essential part. 6. the source or origin of a thing: the root of all evil. 7. a person or family as...
