Interchromosomal recombination in Zea mays.
A new allele of the 27-kD zein locus in maize has been generated by interchromosomal recombination between chromosomes of two different inbred lines. A continuous patch of at least 11,817 bp of inbred W64A, containing the previously characterized Ra allele of the 27-kD zein gene, has been inserted into the genome of A188 by a single crossover. While both junction sequences are conserved, sequen...
متن کاملRecombination in Zea Mays
meiotic process in plants or animals does not necessarily produce the same T:!rcentage of recombinants in male and female germ cells. In maize, the frequency of recombination in a particular chromosomal region is usually higher in microsporogenesis than in megasporogenesis, if a difference exists at all. Chromosomes 2 and 10, according to genetic tests thus far, have similar recombination frequ...
متن کاملPatterns of diversity and recombination along chromosome 1 of maize (Zea mays ssp. mays L.).
We investigate the interplay between genetic diversity and recombination in maize (Zea mays ssp. mays). Genetic diversity was measured in three types of markers: single-nucleotide polymorphisms, indels, and microsatellites. All three were examined in a sample of previously published DNA sequences from 21 loci on maize chromosome 1. Small indels (1-5 bp) were numerous and far more common than la...
متن کاملEpistasis in Maize (zea Mays
ISHER (1918) provided a framework for the characterization of genotypic variance whereby he partitioned it into three components: ( 1 ) a portion associated with the average effects of genes, (2) a portion associated with dominance effects (allelic interactions) of genes, and (3) a portion associated with epistatic effects (nonallelic interactions) of genes. A logical method for the further sub...
متن کاملMaize (Zea mays L.).
Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector. In addition to step-by-step laboratory transformation proced...
