Mapping of QTL affecting fur quality traits (guard hair length, guard hair thickness, density of wool, surface of the fur and quality) and skin length was performed in a three-generation mink population (F2 design). In the parental generation, Nordic Brown mink were crossed reciprocally with American Black short nap mink. In all, 1082 mink encompassing three generations were used for the analys...

Plant root hairs increase the root surface to enhance the uptake of sparingly soluble and immobile nutrients, such as the essential nutrient phosphorus, from the soil. Here, root hair traits and the response to scarce local phosphorus concentration were studied in 166 accessions of Arabidopsis thaliana using split plates. Root hair density and length were correlated, but highly variable among a...

The development of rice varieties for dry direct-seeded conditions can be accelerated by selecting suitable traits. In the present investigation, traits hypothesized to be important for direct-seeded conditions in rainfed systems, including seedling emergence, early vegetative vigour, nutrient uptake, nodal root number, and root hair length and density, were characterized to study the genetic c...

this study was conducted to investigate the hair production and fleece characteristics of hair goats in fars province. the material of the study included a total data of 84 hair goats, which were between kids and adult in male and female goats, respectively. the overall average for fleece weight, fiber length, staple lengths, washing yield, hair fiber diameter, of fiber diameter, breaking force...

The aims of this study were to investigate genotypic variations in root traits at phytomer level of wheat varieties and for recommending a few root traits as selection parameters in future breeding programs. Two separate experiments were conducted to measure their root traits for hydroponically grown wheat plants. In Experiment 1, main axis length, root hair density and diameter differed from p...

Ultraviolet-B (UV-B) radiation is a key but under-researched environmental factor that initiates diverse responses in plants, potentially affecting their distribution. To date, only a few macroecological studies have examined adaptations of plant species to different levels of UV-B. Here, we combined herbarium specimens of Hieracium pilosella L. and Echium vulgare L. with a novel UV-B dataset t...

Abstract Eurasians have ~2% Neanderthal ancestry, but we lack a comprehensive understanding of the genome-wide influence introgression on modern human diseases and traits. Here, quantify contribution introgressed alleles to heritability more than 400 diverse We show that genomic regions in which detectable ancestry remains are depleted for all traits considered, except those related skin hair. ...

A number of root and root hair traits have been proposed as important for nutrient acquisition. However, there is still a need for knowledge on which traits are most important in determining macro- and micronutrient uptake at low soil fertility. This study investigated the variations in root growth vigor and root hair length (RHL) and density (RHD) among spring wheat genotypes and their relatio...

The Rex rabbit is a typical fur breed. Wool density, hair length, wool fineness, and hide area are the main indices of fur quality. We previously found that the CCNA2 gene plays an important role in hair follicle initiation and development, and it is involved in the distinctive wool density of the Rex rabbit. It is an important candidate gene for wool density selection through marker-assis...

BACKGROUND Hair restoration surgery is one of the most commonly performed cosmetic surgery procedure in men. The main aim of the study was to know the effect of follicular unit extraction (FUE) follicular unit extraction (FUE) on donor area in terms of hair mass/density. METHODS Ten male patients undergoing hair restoration by FUE were included. In each patient, ten boxes of 1 cm2 each were ...
