Morphofunctional development of 13-15-year old girls of different somatotypes

Abstract

: The present article provides a comparative analysis of the morphofunctional indicators of 13–15 year old girls of different types of constitution, living in the cities of Pavlodar and Kyzylorda. Most of the studied schoolgirls belonged to the thoracic and muscular types of constitution. Considerable attention is paid to the comparison of such morphological parameters as body length (BL), body mass (BM), chest circumference (CC), wrist strength (WS), cardio-respiratory system indices at rest and after dosed load. The study found that morphological parameters (BL, BM, CC) in girls of two regions increase from asthenoid type to digestive. The results show that the capacity of the cardio-respiratory system of girls of the digestive type is less compared with schoolgirls of other somatotypes. should not it not it of the preserving the structure of the article - introduction/ problem statement /goals/ history, research methods, results /discussion, conclusion).

The capsid protein (СР) P41 is required for virion formation and facilitates long distance movement of the virus. Along with RNAi suppression, P19 protein is involved in the development of severe disease symptoms in N. benthamiana and elicitation of Hypersensitive Response (HR) in tobacco. Our results show that wild type TBSV infection of Solanum lycopersicum (cv. Money maker) triggers resistance to the virus. Despite detectable accumulation levels of P19 protein in leaf and root tissues, the infection was not accompanied with obvious disease symptoms. Contrastingly, inoculation with TBSV mutant, lacking capsid protein P41 demonstrated susceptibility to TBSV. Moreover, Chl-FI analysis of plants infected with virus exhibited significant changes in metabolism. Our data suggests that in response to CP expression tomato plants have evolved defense mechanisms to resist viral infection.
