Mutants from Maize Plants Heterozygous R R and Their Association with Crossing over.
HE R locus alleles in maize, together with certain complementary genes, Tcondition the production of anthocyanin pigment in the aleurone layer of the seed and in such plant parts as the roots, leaf sheaths, and anther walls. In the designation of the common alleles (EMERSON, BEADLE and FRASER 1935), R and r are used to indicate the presence and absence, respectively. of anthocyanin in the aleur...
متن کاملRelative insensitivity of enhanced Rr to paramutation in maize plants heterozygous for the stippled allele.
ATA presented in the preceding article (BRINK and BLACKWOOD 1961) D demonstrate that the effect of R' on aleurone color in maize is enhanced when the factor is carried by, or passed through, either of two reciprocal translocations, T2-10a and T4-lob, involving breaks in the long arm of chromosome 10 proximal to, but well removed from, the R locus. The change in phenotype is from darkly mottled ...
متن کاملMeiotic Crossing Over in Maize Knob Heterochromatin.
There is ample evidence that crossing over is suppressed in heterochromatin associated with centromeres and nucleolus organizers (NORs). This characteristic has been attributed to all heterochromatin, but the generalization may not be justified. To investigate the relationship of crossing over to heterochromatin that is not associated with centromeres or NORs, we used a combination of fluoresce...

Crossing over and Gene Rearrangement in Flowering Plants.
K i n d s of gene rearrangement “ Crossing over” exists apparently in all those flowering plants which have been sufficiently investigated with regard to it. (By itself, it does not rearrange different genes, but only exchanges alleles.) Genetically i t consists in exchange of normally equal and homologous segments of a gene string (MORGAN 1911, STURTEVANT 1915, MULLER 1916). It has been proved...
