In order to localize the genes coding for zein, the major storage protein of maize endosperm, zein 125I-mRNA and 3H-cDNA labelled at high specific activity were used for in situ hybridization on heterozygous interchanges and paracentric inversions of the KYS strain of Zea mays. The analysis of the diplotene-metaphase I microsporocytes indicated the presence of zein structural genes on the long arm of chromosomes 4 and 5, the short arm of chromosome 7 and the distal segment of the long arm of chromosome 10. The two hybridization sites on chromosomes 7 and 10 are found near opaque-2 and opaque-7 loci which are known to regulate zein synthesis. The present data are discussed in relation to results obtained by other authors using genetical mapping of zein genes. |
