Chromosomal Interchanges in Maize.
Chromosomal interchanges, or reciprocal translocations, in maize are of primary interest because of the opportunities they offer for the study of chromosome behavior and crossing over. The great volume of work which has been done on crossing over and on translocations in Drosophila has yielded an abundance of statistical data on crossing over and chromosome distribution. For this type of work D...
متن کاملTelomere-mediated chromosomal truncation in maize.
Direct repeats of Arabidopsis telomeric sequence were constructed to test telomere-mediated chromosomal truncation in maize. Two constructs with 2.6 kb of telomeric sequence were used to transform maize immature embryos by Agrobacterium-mediated transformation. One hundred seventy-six transgenic lines were recovered in which 231 transgene loci were revealed by a FISH analysis. To analyze chromo...
متن کاملGenetic Detection of Chromosomal Interchanges and its Consequence on Plant Breeding: a Review
Chromosomal interchanges are of primary interest because of the opportunities they offer for the study of chromosome behavior and crossing over. The great volume of work which has already been done on crossing over and on translocations but still lack of understanding among the graduates students. Hence, continue discussions and question still to be made on this terminology. This paper gives th...
متن کاملInterchanges and statistical designs
Let D be a statistical design consisting of v varieties on b blocks. We say it is binary if a variety occurs at most once on every block. For varieties p and q on blocks x and y respectively, we can obtain design D' from D by interchanging p and q (so p is on y and q is on x). We say that the exchange is binary if either x y, or p q, or: q not on x and p not on y. If D is binary then D' is also...
متن کاملMeiotic drive of chromosomal knobs reshaped the maize genome.
Meiotic drive is the subversion of meiosis so that particular genes are preferentially transmitted to the progeny. Meiotic drive generally causes the preferential segregation of small regions of the genome; however, in maize we propose that meiotic drive is responsible for the evolution of large repetitive DNA arrays on all chromosomes. A maize meiotic drive locus found on an uncommon form of c...
