Molnár I, Linc G, Dulai SD Nagy E and Molnár-Láng M (2007). Ability of chromosome 4H to compensate for 4D in response to drought stress in a newly developed and identified wheat-barley 4H(4D) disomic substitution line. Plant Breeding 126(4):369–374. (DOI: 10.1111/j.1439-0523.2007.01300.x).

A spontaneously developed wheat–barley 4H(4D) disomic substitution line was identified cytogenetically using genomic in situ hybridization (GISH), multicolour fluorescent in situ hybridization (FISH) and microsatellite markers. The ability of the barley 4H chromosome to compensate for wheat 4D in response to mild drought stress was also investigated. In the barley cv. ‘Betzes’ and the 4H(4D) substitution line, mild osmotic stress induced intensive stomatal closure, resulting in reduced water loss through transpiration and unchanged relative water content in the leaves.
