What is w4-Mutable line in soybean about?

An unstable mutation for anthocyanin pigmentation in soybean (Glycine max [L.] Merr.) was identified in 1983. The mutability is conditioned by an allele at the w4 locus that is recessive to wild type. The population containing the mutable allele is known as the w4-mutable line. Most plants in the line have chimeric flowers with purple sectors on a near-white background. The mutable allele yields germinal revertants at a rate that varies from 5 to 10% per generation, and the revertant alleles are stable. Approximately 1 YO of the progenies derived from germinal revertant plants contain mutations at other loci. These features, as well as the occurrence of pale flower phenotypes and changes of state, suggest that a transposable element system is producing the unstable phenotype. Several new mutants were isolated in an experiment designed to tag loci. The first three chlorophyll-deficient mutants found (CD-1, CD-2, and CD-3) are inherited as single-gene recessives. Each of the mutants lacks the same two mitochondrial malate dehydrogenase (MDH) bands. No recombination has been detected between the MDH phenotype and the chlorophyll-deficient phenotype. Genetic data indicate that the thre
