“…A. Hamoud,and A. S. Haidar Cytologia 56 they have no effect on the protein quantities of some other taxa. This supports the suggestion that supernumerary chromosomes may exert regulatory effects on the nucleus, modifying or suppressing gene action (Himes 1967, Jones and Rees 1968, and Kirk Jones 1970. The data of the water and buffer extracted proteins displayed a continuous variation (Table 1).…”

“…Selection against individuals carrying a large number of B chromosomes, expressed as reduced seed-set, was observed in rye by Muntzing (1943) and by Jones and Rees (1967). Such plants also showed reduced height and (Jones and Rees, 1968). Reduced seed-set and pollen abortion were also found in Lilium callosum carrying supernumerary chromosomes (Kayano, 1962).…”

Supernumerary chromosomes and chiasma distribution in Triticum speltoides

SUMMARYSupernumerary (B) chromosomes were found in two Out of three population samples of Triticum .cpeltoides from Turkey and further samples were studied from two Israeli populations previously reported to consist of a high frequency of B-carriers (Simchen et al., 1971). In the two Israeli populations, plants with B chromosomes have a lower frequency of terminal chiasmata and a higher frequency of interstitial chiasmata. This effect is proportional to the number of B chromosomes per plant, which varies in one population between 0 and 8 and in the other between 0 and 3. Evidence for selection against plants with a high number of Bs is presented.

“…DNAs highly purified from batches of four to six wheat plants and from individual rye plants with different numbers of rye B chromosomes were immobilised on nitrocellulose filters and hybridised to 3H-labelled rRNA in 6 x SSC at 70°C for 3 hrs. The percentage hybridisation values and numbers of genes were calculated from the percentage of the DNA on each filter binding to rRNA and from the DNA content per cell assuming that each B chromosome constituted 55 per cent of the rye diploid genome (Jones and Rees, 1968) and 29 per cent of the wheat hexaploid genome. Because the production of the B chromosome carrying wheat plants involved backcrossing to Chinese Spring wheat six times we have assumed the wheat genome is the same in all these plants.…”

SUMMARYThe presence of ribosomal RNA genes on rye supernumerary B chromosomes from three different rye populations has been investigated by ribosomal RNA/DNA hybridisation. DNAs were purified from wheat plants containing zero, two, three or four rye B chromosomes and from individual plants from two rye populations containing different numbers of B chromosomes. The number of ribosomal RNA genes was highly correlated with rye B chromosome number in the wheat plants but not in the rye plants. It is suggested, therefore, that not all rye B chromosomes are the same and that those transferred into the wheat genetic background each carry approximately 650 ribosomal RNA genes.
