The map positions of five previously described phytochrome genes have been determined in tomato (Lycopersicon esculentumMill.) The position of the yg-2gene on chromosome 12 has been confirmed and the classical map revised. The position of the phytochrome A (phy A)-deficient frimutants has been refined by revising the classical map of chromosome 10. The position of the PhyAgene is indistinguishable from that of the frilocus. The putative phyB1-deficient trimutants were mapped by classical and RFLP analysis to chromosome 1. The PhyB1gene, as predicted, was located at the same position. Several mutants with the high pigment (hp)phenotype, which exaggerates phytochrome responses, have been reported. Allelism tests confirmed that the hp-2mutant is not allelic to other previously described hp(proposed here to be called hp-1) mutants and a second stronger hp-2allele (hp-2j) was identified. The hp-2gene was mapped to the classical, as well as the RFLP, map of chromosome 1. |
