Lignin is the main component of walnut endocarp, however, we know little about transcriptional responses and its potential regulatory mechanisms lignin formation in endocarp. Here selected two genotypes with different endocarp thickness, ‘Liaoning 7’ (L7) ‘Zanmei’ (ZM; thicker than L7), to study response mechanism that caused difference this character between them. The time regularity depositio...

Walnut, Juglans regia L. is the most economically important member of the Juglandaceae family and is the most valuable nut crop in the world. Recently, it has increased greatly in acreage and in production. Although a number of research programs about plant apomixis have been carried out around the world, few were representd by the Juglandaceae. This paper presents a brief review of the current...

We investigated the composition of free amino acids in walnut (Juglans regia L.) seeds (embryo and cotyledons). We also examined xylem transport of free amino acids in young seedlings grown in the absence of external nutrients. A relatively high concentration of free alanine was found in seed tissue, whereas a relatively high concentration of citrulline was detected in young seedlings. Citrulli...

The aqueous extracts (15 micrograms ml-1 medium) of 22 plants used in folkloric medicine in Palestine were investigated for their antifungal activity and minimum inhibitory concentrations (MICs) against nine isolates of Microsporum canis, Trichophyton mentagrophytes and Trichophyton violaceum. The extract of the different plant species reduced colony growth of the three dermatophytes by 36 to 1...

We present a continuous model for the diffusion of sugars across intact plant leaf cuticles. It is based on the flow of sugars from a source, representing the leaf apoplast, to a sink, in the shape of a hemispherical drop of water on the outside of the cuticle. Flow is a function of the difference between sugar concentrations C(Source) and C(Sink) , permeability P of the cuticle, volume V(Sink)...

Juglans regia, commonly known as the Walnut tree, is a type of deciduous tree. The tree has many important parts, seed, bark, husk, leaves, oil, shell fruit and kernel. plant been used in its crude form since ages. kernel holds nutritional value. leaves contain an essential oil which extracted used. husk contains steroids vitamins amongst other useful compounds. are topically antipyretic, analg...

Walnut, Juglans regia L., is known for its insecticidal activities to a range of herbivores and microbes. Isolation and identification of bioactive compounds from walnut is a potential approach for the development of new pesticides. Laboratory experiments were carried out to investigate the acaricidal activities of green husk extracts of walnut. Bioassay-guided fractionation of petroleum-ether ...

Simple sequence repeat (SSR) markers were used to authenticate ramets of 11 Persian walnut ( Juglans regia L.) varieties. All varieties and 28 their (n = 39) genotyped with 17 SSR markers. The genetic profiles revealed two off-types: the Serr 4 (S4) Vina 1 (V1). fingerprints individuating possible using 13 polymorphic SSRs that could be in future identify clones these Except for ‘Chandler’, eac...
