The componental composition of electrophoretic spectra of gliadin in Triticum spelta L. was studied. By analogy with common wheat T. aestivum L., it was established that genes controlling gliadin components in spelt are also located in short arms of chromosomes of homeological groups 1 and 6. Analysis of gliadin spectra in F2 grains from the crosses k-20539 × Ershovskaya 32 and k-20558 × Ershovskaya 32 revealed linkage of some components and their grouping into blocks (alleles) of coinherited gliadin components. Alleles of gliadin-coding loci identical to alleles of common wheat and new alleles earlier unknown for wheat populations have been identified.

    DFNB89 is a novel autosomal recessive nonsyndromic hearing impairment (ARNSHI) locus that was mapped to 16q21-q23.2. Linkage to the region was established by carrying out genome-wide linkage scans in two unrelated, consanguineous Pakistani families segregating ARNSHI. The maximum multipoint LOD...

    Background: Tandemly Arrayed Gene (TAG) clusters are groups of paralogous genes that are found adjacent on a chromosome. TAGs represent an important repertoire of genes in eukaryotes. In addition to tandem duplication events, TAG clusters are affected during their evolution by other mechanisms,...
