Effect of ultraviolet-sensitive mutants on gene inheritance in mycobacterial matings.

چکیده

Evidence is presented suggesting that a rec mutation in one strain (presumably female) of a mating pair of Mycobacterium smegmatis strains prevented the appearance of recombinants, whereas a rec mutation in the other strain (presumably male) did not.

Genetic analysis of tox+ and tox- bacteriophages of Corynebacterium diphtheriae.

A series of mutants derived from the temperate corynebacteriophages beta(tox+), gamma(tox-), and L(tox+) was isolated and characterized. In three-factor crosses between mutant beta phages the relative map order of the genetic markers determining extended host ranges (h and h') and loss of ability to lysogenize (c) was found to be h--c--h'. Recombination between markers was observed in matings b...

Nuclear and Cytoplasmic Inheritance of Salt Tolerance in Bread Wheat Plants Based on Ion Contents and Biological Yield

Although inter-variety variability for salt tolerance has been reported in bread wheat plants, little information is available on the genetic control of ion contents and biomass yield under saline conditions. A diallel cross, including reciprocals of two salt tolerant, two moderately tolerant and two sensitive Iranian and exotic bread wheat varieties, was analyzed to investigate the inheritance...

Ultraviolet-sensitive mutants in Neurospora crassa.

ADIATION-SENSITIVE mutants in bacteria have been reported repeatedly in recent years (s,ee SETLOW 1966). Several loci concerned with sensitivity have been mapped. Some of these mutants not only lacked the ability to repair damaged DNA but also failed to undergo genetic recombination (CLARK and MARGULIES 1965; HOWARD-FLANDERS and THERIOT 1966; VAN DE PUTTE et al. 1966). Among the eucaryotic orga...

Virulence Function of Pectobacterium atrosepticum Secretion System Mutants on Evaluation of Some Solanum tuberosum Resistance Genes

Background: P. atrosepticum is a commercially important pathogen. It causes blackleg in the field and soft rot of tubers after the harvest. This effect is due to secretion of depolymerases and other virulence factors by several mechanisms including T3SS Objectives: The effect of bacterial T3SS on Solanum tuberosum (S. tuberosum) varieties and its re...

mune phages the c markers of phages j3 and y failed to segregate from the imm markers which determine the specificity of lysogenic immunity in these phages. The factor which directs the synthesis of diphtherial toxin during infection of appropriate corynebacterial hosts by toxinogenic corynebacteriophages is designated tox+. It was possible to show that the tox+ determinant of phage ,B behaves ...
