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 کاملRestriction endonucleases induce chromosomal aberrations in barley.
The clastogenic ability of the restriction endonucleases (MspI, HpaII and HaeIII) in germinating seeds of reconstructed barley karyotype was assessed. An effective induction of chromosomal aberrations after restrictase treatment was observed. The frequency, types and cell-cycle dependence of the observed abnormalities are discussed in relation to the distinct characteristics of the enzymes and ...
متن کاملGenetic Analysis of Two Chromosome Interchanges I N Barley from F 2 Data '
HE use of backcross data for the genetic analysis involving an interchange T between two non-homologous chromosomes has been clearly defined and reviewed. JOACHIM (1947) has presented tables to facilitate the use of the product method for the analysis of Fz data involving semisterility. In a selfpollinated plant such as barley, this method presents a convenient tool for the determination of lin...
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 کاملChromosomal assignment and deletion mapping of barley EST markers.
From about 10000 PCR-based EST markers of barley we chose 1421 EST markers that were demonstrated to be amplified differently by PCR between wheat (Triticum aestivum cv. Chinese Spring) and barley (Hordeum vulgare cv. Betzes). We assigned them to the seven barley chromosomes (1H to 7H) by PCR analysis using a set of wheat-barley chromosome addition lines. We successfully assigned 701 (49.3%) ES...
