Genetics of anthocyaninless rye

Genetics of anthocyaninless rye Six nonallelic genes have been discovered in rye, the recessive mutations of which lead to a lack of anthocyanin. Crosses with these mutants showed that 13 new anthocyaninless lines carry mutations in the gene vi1, whereas vi2/6 mutations were identified only in single cases. Inheritance of the vi1/6 mutations in the progeny of hybrids with the wild type (Line 7, L7) corresponds to a monohybrid segregation. Segregation for three of these mutations (vi2, vi4, and vi5) in hybrids with line 2 is characterized by anthocyaninless deficiency in plants. We discuss the reasons for such deviations and the previously published data for the identification of the six anthocyanin pigmentation genes in the rye using trisomic analysis. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

Six nonallelic genes have been discovered in rye, the recessive mutations of which lead to a lack of anthocyanin. Crosses with these mutants showed that 13 new anthocyaninless lines carry mutations in the gene vi1, whereas vi2/6 mutations were identified only in single cases. Inheritance of the vi1/6 mutations in the progeny of hybrids with the wild type (Line 7, L7) corresponds to a monohybrid segregation. Segregation for three of these mutations (vi2, vi4, and vi5) in hybrids with line 2 is characterized by anthocyaninless deficiency in plants. We discuss the reasons for such deviations and the previously published data for the identification of the six anthocyanin pigmentation genes in the rye using trisomic analysis.
