Chromosome pairing in tetraploid rye with monosomic-substitution wheat chromosomes.
In tetraploid rye with single-substitution wheat chromosomes - 1A, 2A, 5A, 6A, 7A, 3B, 5B, 7B - chromosome pairing was analysed at metaphase I in PMCs with the C-banding method. The frequency of univalents of chromosome 1A was considerably higher than that of the other four wheat chromosomes of genome A (6A, 5A, 7A and 2A). Among chromosomes of genome B, the lowest mean frequency of univalents ...
متن کاملQTL Underlying Self-Fertility in Tetraploid Alfalfa
A potential strategy to decrease the levels of self-seed production during the seed increase stages of alfalfa (Medicago sativa L.) synthetic cultivar development is selection for decreased self-fertility. The underlying genetics of this trait have not been elucidated and, therefore, a study was designed to identify genetic determinants of alfalfa self-fertility. An F1 mapping population develo...
متن کاملFertility compensation of cornerstone male sterility of wheat by rye.
The genome of rye is known to compensate for the lost male-fertility gene(s) of wheat chromosome arm 4Aalpha in the Cornerstone male-sterility mutant. A search for the rye chromosome(s) involved in this compensation showed that chromosomes 2R and 4R are responsible. Only the short arms of these two chromosomes are the operative ones. Chromosome arm 4RS compensates in an erratic way, whereas 2RS...
متن کاملThe influence of rye cytoplasm on meiotic stability of tetraploid Secalotriticum.
Chromosome pairing in tetraploid Secalotriticum was analysed. In the studied plants wheat chromosomes in PMCs during metaphase I showed a higher degree of pairing, in comparison to the rye genome. This is reflected in a very low frequency of univalents and a higher frequency of ring bivalents. The occurrence of wheat univalents was dependent on wheat mixogenome. In plants with an unstabilized f...
متن کاملTetraploid cells of enhanced green fluorescent protein transgenic mice in tetraploid/diploid-chimeric embryos.
We succeeded in noninvasively analyzing the distribution of tetraploid (4n) cells in tetraploid<-->diploid (4n<-->2n) chimeric embryos by using enhanced green fluorescent protein (EGFP) transgenic (Tg) mouse embryos. We also evaluated whether this technique of analyzing 4n-cells in EGFP Tg 4n<-->2n chimeric embryos could be used to determine which characteristics of 4n-cells cause the death of ...
