Marker enzyme phenotype ratios in agamospermous sugarbeet progenies as a demonstration of multidimensional encoding of inherited information in plants

نویسنده

چکیده

It has been demonstrated that the observed ratio of phenotypes of marker enzymes in some sugarbeet plants produced by mitotic agamospermy can be explained by different degrees of endoreduplication of chromosomes carrying different alleles of the enzyme loci. In these plants, different patterns of variability of the enzymes controlled by the linked loci suggest different degrees of endoreduplication of different chromosomal regions. A concept of multidimensional encoding of inherited information in eukaryotes has been proposed. _________________________________________________________________________

Phenotypic class ratios as marker signs of different types of agamospermy

This article focuses on the development of the method for the genetic classification of agamospermous reproduction types in plants using sugar beet as an example. The classification feasibility is ensured by the use of isozymes as genetic markers allowing the identification of all three phenotypic classes in the progeny of individual heterozygous diploid plant and is based on different phenotyp...

Post-meiotic apozygotic combinatory process in sugar beet (Beta vulgaris L.)

The effect of colchicine on phenotypic classes ratio of the enzyme locus controlling alcohol dehydrogenase (ADH1) in sugar beet agamospermous progenies was analysed. The obtained data are indicative of the thing that colchicine causes polytenization of homological chromosome regions carrying marker locus Adh1 alleles. Theoretical calculation of the formation of egg cells frequencies and those o...

Genetic proof of chromatin diminution under mitotic agamospermy

The previously published data are examined on the base of the hypothesis about existence of differential polyteny of chromosomes and excess chromatin diminution during the first stages of embryogenesis. It has been concluded that available data provide the genetic proof that chromatin diminution is one of the mechanisms underlying the origin of polymorphism in sugar beet agamospermous progenies...

DEMONSTRATION OF LOCAL ANTITOXOPLASMIC IMMUNOGLOBULIN G PRODUCTION IN OCULAR TOXOPLASMOSIS, TRACED BY ENZYME IMMUNOASSAY OF AQUEOUS HUMOR AND SERUM

Forty patients with cataracts, as well as 40 patients with proven ocular toxoplasmosis were enrolled in this prospective clinical study. Serum IgG and aqueous IgG in both groups were measured by enzyme-linked immunosorbent assay (ELISA) and the corresponding ratios were calculated. Serum IgG/aqueous humor IgG ratio was less than 100 in the patient group and more than 100 in the control gro...

Functional Assessment of an Overexpressed Arabidopsis Purple Acid Phosphatase Gene (Atpap26) in Tobacco Plants

Background: Overexpression of known genes encoding key phosphate (Pi)-metabolizing enzymes, such as acid phosphatases (APases), is presumed to help plants with Pi availability and absorption as they are mostly exposed to suboptimal environmental conditions for this vital element.Objectives: In this study, the overexpression effect of AtPAP26, one of the m...
