Nuclear organization and chromosome segregation.
The genetic information underlying plant form and function is contained within the cell nucleus in the form of complex, dynamic DNA–protein structures—the chromosomes. The faithful transmission of these structures during mitosis and meiosis requires extensive chromosome reorganization and the formation of a unique, transient structure, the spindle, which serves to segregate chromosomes to daugh...
متن کاملMutations of phage P22 affecting phage DNA synthesis and lysogenization.
Two temperature-sensitive mutants of phage P22, ts18.1 and ts12.1, are described which have recessive DNA-negative phenotypes. At high temperature they fail to synthesize phage DNA. In mixed infection with the two mutants or either mutant and wild-type phage, DNA synthesis and phage production are normal. In addition, under non-permissive conditions, these mutants fail to lysogenize and show do...
متن کاملControl of lysogenization by phage P22. II. Mutations (clyA) in the cl gene that cause increased lysogenization.
(Received 10 NovembPr IYSO, and in revised form 24 April 19X1) p12 cly mutants lysogenize at very high frequency after infection of wild-type Salmonella. One class of P22 cly mutations, clyA mutations, are shown to map within the P22 cl gene and to increase the activity of t,he cl gene product during establishment of lysogeny. The P22 clyil mutations also appear to affect c%-repressor gene expr...

متن کاملRelationship of nuclear segregation and macroconidial germination in Microsporum gypseum.
Microsporum gypseum macroconidia germinated at 37 C possessed from one to eight nuclei per germinated spore compartment. The distribution of nuclei per spore compartment was the result of a random packaging of nuclei from the available nuclear population. Partial inhibition of germination by incubation at 25 C or at 37 C in the presence of 10(-4)m phenyl methyl sulfonyl-fluoride resulted in an ...
