Diamondback moth (DBM), Plutella xylostella L. is the most injurious defoliage insect pest of canola in Ardabil province of Iran. It occurs annually and causes damage in canola fields. This study was performed to identify QTLs controlling resistance to diamondback moth using SSR and RAPD markers. An F2:4 population of 180 families derived from crossing between cv. ‘SLMO46’ and cv. ‘Quantum’ wer...

Physical mapping of BACs by fluorescent in situ hybridization (FISH) was used to analyze the liguleless (lg-1) linkage group in sorghum and compare it to the conserved region in rice and maize. Six liguleless-associated rice restriction fragment length polymorphism (RFLP) markers were used to select 16 homeologous sorghum BACs, which were in turn used to physically map the liguleless linkage gr...

the incidence of pre-lingual hearing loss (hl) is about 1 in 1000 neonates. more than 60% of cases are inherited. non-syndromic hl (nshl) is extremely heterogeneous: more than 130 loci have been identified so far. the most common form of nshl is the autosomal recessive form (arnshl). in this study, a cohort of 36 big arnshl pedigrees with 4 or more patients from 7 provinces of iran was investig...

this study determines the value of linkage analysis using six rflp markers for carrier detection and prenatal diagnosis in familial dmd/bmd cases and their family members for the first time in the iranian population. we studied the dystrophin gene in 33 unrelated patients with clinical diagnosis of dmd or bmd. subsequently, we determined the rate of heterozygosity for six intragenic rflp marker...

Using an interspecific cross, gene linkage relationships among members of the murine complement receptor-related genes, C4bp, Cfh, Mcry, and Mcr2, were analyzed by segregation of RFLP in 200 mice. The human homologues of these genes are tightly linked, composing the RCA locus, which maps to human chromosome (Chr.)1q32, within a large linkage group conserved between human Chr.1q21-32 and mouse C...

The autosome in Searle's X-autosome translocation has been shown to be chromosome 16. The breakpoint in chromosome 16 is slightly proximal to the middle and in the X is slightly distal to the middle.-Available evidence indicates that either Linkage Group XV or Linkage Group XIX is carried on chromosome 16.-The centromere of the X chromosome is at the spf end of the linkage group.

A chromosome rearrangement has been isolated and characterized in Sordaria brevicollis. Crosses to spore color mutants on each of the seven linkage groups have enabled the breakpoints to be mapped. The simplest hypothesis to account for the results is that a piece of linkage group VI has been translocated to linkage group V and inserted 2.7 map units from its centromere. Previous reports of mar...
