A simple method is described by which sex chromatin can be studied in the cells of the external root sheath of single hairs. From a human capital hair many thousands of scorable nuclei can be obtained. Since this material is suitable for orcein staining, preparations are ready for analysis within a few minutes.

Root hairs are single cells specialized in the absorption of water and nutrients. Growing root hairs requires intensive cell wall changes to accommodate cell expansion at the apical end by a process known as tip growth. The cell wall of plants is a very rigid structure comprised largely of polysaccharides and hydroxyproline-rich O-glycoproteins.

Root hairs are projections from the epidermal cells of the root that are thought to increase its effective surface area for nutrient and water uptake, 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.

Image analysis of hair — Hair roots extraction
2017 56th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2017There are many people suffering from loss of hair or thinning hair. There are, however, no methods to quantitatively know their hair condition such as hair density and hair thickness without cutting the hairs. Our final target is to develop a system which enables general people to easily and quantitatively know their hair condition without cutting the ...

Botanical Gazette, 1936
In the members of the monocotyledons investigated there exists a so-called "persistent" hirsuteness of practically the whole root system. The constituent cutinized hairs have been found to be of secondary cortical origin, superseding the primary epidermal ones. It seems logical that this condition may be associated with the lack of secondary thickening,

Regulation and functional diversification of root hairs
Seminars in Cell & Developmental Biology, 2018Root hairs result from the polar outgrowth of root epidermis cells in vascular plants. Root hair development processes are regulated by intrinsic genetic programs, which are flexibly modulated by environmental conditions, such as nutrient availability. Basic programs for root hair development were present in early land plants. Subsequently, some plants

DEVELOPMENT Adult hair follicles sustain repeated cycles of hair loss and regrowth. Stem cells reside within a small niche, called the bulge, located in the upper part of the hair follicle. These stem cells are responsible for driving this cycle of growth and can repopulate follicles and surrounding epidermis damaged by wounding.

In this review, the value of root hairs as a model system for a broad range of electrophysiological experiments is highlighted by an introductory case study of their use for in situ measurements of vacuolar electrophysiology. Then, the basic tenets of electrophysiological measurements are presented: the electrical properties of the cell and how they ...

During growth and development of the plant root, root hairs often play a key role in nodulation, and water and ion uptake. Root hairs are not an obligatory cell type on the root surface. However, when present, they have highly active respiration (Connoly and Berlyn 1996), and are known to preferentially express a number of transport proteins, such as ...

The cytoskeleton is a dynamic filamentous structure composed of at least actin and microtubule networks. Actin and microtubules are no different structurally from their animal and fungal counterparts. However, the strategies of cell differentiation and development in plants require this network to respond appropriately to plant-specific developmental ...
