Chromosomal Location of Genes Encoding Barley (1→3, 1→4)-β-Glucan 4-Glucanohydrolases

Abstract
Preparations of DNA from wheat (Triticum aestivum, cv Chinese Spring), barley (Hordeum vulgare, cv Betzes) and six euplasmic wheat-barley addition lines were digested to completion with restriction endonucleases and the products probed by Southern blot analysis using a cDNA-encoding barley (1.fwdarw.3,1.fwdarw.4)-.beta.-glucanase isoenzyme II. It is shown that one of the barley (1.fwdarw.3,1.fwdarw.4)-.beta.-glucanase genes is located on chromosome 1.
