Abstract
Gene-dosage responses for a group of 6 wheat endosperm proteins were investigated by using compensated nulli-tetrasomic lines of cv. Chinese spring. Practically linear dosage responses were observed for all the proteins. However, for 2 of the proteins (and probably for a 3rd one), the net output of protein, at each dosage of its structural gene, was 30-80% higher when the chromosome carrying an active homoeogene was absent. The possible significance of this effect in connection with the loss of gene redundancy undergone by polyploids is discussed.This publication has 22 references indexed in Scilit:
