Clonal variation in paramecium. II. A comparison of stable and unstable clones of the same serotype.

چکیده
Paramecium generally expresses only one antigen on its surface from among an array of antigens. This mutual exclusion of antigens now has been shown in certain instances to be illusory. Unstable clones which will give rise to subclones with new serotypes possess several antigens. Unstable clones, even though they manifest only one serotype, continually manufacture an antigen other than the surface antigen characteristic of the serotype.

Clonal variation in paramecium. I. Persistent unstable clones.
Clones of Paramecium of identical serotype when cultured in test tubes may differ in their ability to give rise to subclones of this serotype. Characteristically, stable clones yield progeny indistinguishable from their parents, while from unstable clones diverse subclones with new serotypes can be isolated repeatedly. Stable lines are resistant to changes in culture medium and also are unaffec...

To improve commercial grapevine cultivars, it is necessary to apply such methods that by cultivation of a certain number of vines in a certain area, higher yield could be harvested. To achieve such a goal, healthy stocks with resistant to pests and diseases, high fructification and high quality of vines are needed. All these properties can be obtained successfully through clonal selection. Viti...

SUMMARY: At present, measurment of glycosylated hemoglobin, especially the stable fraction of hemoglobin (HbA1c) is one of the ways to control diabetes because this measurment can demonstrate total glycemia during last 1.2.3 months. Glycosylated hemoglobin is seen in 3 forms: Ala Alb A1c. Among these hemoglobin Alc is quantitively more than other 2 forms and its difference with other hemoglobi...
متن کاملRepression of gene expression by cdll products in Paramecium.
individual paramecium can synthesize many serologically distinct surface Ayntigens, each of which is specified by a separate locus. The environment, acting through the cytoplasm, selects which of these ciliary proteins is to be expressed. All of the remaining immobilization antigens are excluded from expression (BEALE 1957'). In a constant environment each serotype can be passed on and maintain...

Tea (C. sinensis L.) is the most important beverage crop in Iran and genetic base of current Iranian tea shrubs were achieved from three mass seeds namely: Dhongan, Batjan and Raighur. In this study, genetic diversity of 30 cultivated tea clones were evaluated using 45 RAPD markers and 13 morphological and 4 chemical characters respectively. Sixteen and of 45 markers produced 96 bands that 89 b...
