Myelination of axons is a prerequisite for the rapid propagation of nerve impulses, and thus for the proper functioning of the nervous system. Phenotypic analysis of genetically engineered mice has provided evidence that cell adhesion molecules are critically involved in the interaction of myelin-forming glial cells with axons, the formation of regularly spaced myelin internodes along axons and...

Aim. Evaluation of the role different internodes and leaf sheaths winter wheat stem in storage remobilization reserve water-soluble carbohydrates (WSC) under natural water deficit order to develop effective criteria for selection high-yielding genotypes. Methods. The specific content total amount WSC at onset end grain filling quantity remobilized parts were determined. Results. It was found th...

Abstract Five bread wheat (Triticum aestivum L.) cultivars including Kavir, Pishtaz, Niknejad, Omid and Roshan were evaluated in a split plot experiment based on randomized complete block design with three replications. Water stress and well-watered conditions were assigned to the main plots and varieties to the subplots. Water stress was imposed by withholding irrigation at the booting stage....

An incomplete diallel cross study comprising of seven bread wheat (Triticum aestivum L.) cultivars was carried out with parents and F1 progeny to determine heterosis, combining ability, gene action, and correlations for plant height and its components. The results showed that heterosis and heterobeltiosis occurred in plant height, spike length, peduncle length, length of the second internode fr...

This research is related to the evaluation of vegetative growth parameters, initial yield and incidence pests diseases twelve Arabica coffee cultivars submitted subtropical humidity environment Vale do Ribeira Paulista, Brazil. The experiment was performed in Experimental Campus UNESP Registro, a randomized block design, with three replications. Stem diameter, number plagiotropic branches, plan...

Aim. The goal of this work was to study the effect drought in critical phase ontogenesis on growth and productivity breed winter wheat plants (Triticum aestivum L.). Methods. Wheat cultivars Darunok Podillya Podolyanka were grown under optimal nutrition well-water conditions until earing-flowering phase, after that experimental transferred regime for 8 days, water supply restored end vegetation...

Gibberellic acid increases the level of RNA polymerase associated with chromatin isolated from expanding internodes of light-grown, dwarf pea plants (Pisum sativum L.), without a detectable increase in the amount of DNA template available.

Schwann cells are recognized by their capacity of producing single internodes of myelin around axons of the peripheral nervous system. In the ethidium bromide (EB) model of primary demyelination in the brainstem, it is observed the entry of Schwann cells into the central nervous system in order to contribute to the myelin repair performed by the oligodendrocytes that survived to the EB gliotoxi...
