Spontaneous morphological alterations of chromosomes in Nicotiana hybrids.

چکیده
EVERAL workers have already reported that hybridization between Nicotiana species can bring about chromosome instability. One conspicuous case is loss of somatic plumbaginifolia chromosomes in derivatives of N . tabacum X N . plumbaginifolia hybrids (MOAV 1961). The present paper deals with another peculiarity of alien chromosomes in tobacco hybrid derivatives. It reports on heritable changes in size and stainability detected in N . plumbgginifolia chromosomes after their addition to N . tabacum genomes.

Cytological investigations of the interspecific hybrids of Nicotiana tabacum L. x N. glauca Grah.
Interspecific amphihaploid and amphidiploid hybrids between Nicotiana glauca Grah. (2n = 24) and N. tabacum L. (2n = 48) cultivars BY 103 and K 326 were analysed. F1 amphihaploids (2n = 36) were viable and completely self- and cross-sterile, and mostly univalents were present during meiosis (with pairing range from 0 to 5). In some meiocytes, meiotic irregularities were observed, such as sporad...
متن کاملInheritance in Nicotiana Tabacum. Xix. Identification of the Tabacum Chromosome Replaced by One from N. Glutinosa in Mosaic-Resistant Holmes Samsoun Tobacco.
N ORDER to produce better cultivated plants and animab by hydridizaI tion, the breeder usually relies upon an exchange of genic material between varieties or species. This is accomplished by conjugation of the chromosomes in pairs during meiosis and subsequent crossing over. In interspecific hybrids, however, chromosomes frequently do not conjugate. Therefore the utilization of valuable genic m...
متن کاملIdentification of Nicotiana tabacum Linkage Group Corresponding to the Q Chromosome Gene(s) Involved in Hybrid Lethality
BACKGROUND A linkage map consisting of 24 linkage groups has been constructed using simple sequence repeat (SSR) markers in Nicotiana tabacum. However, chromosomal assignments of all linkage groups have not yet been made. The Q chromosome in N. tabacum encodes a gene or genes triggering hybrid lethality, a phenomenon that causes death of hybrids derived from some crosses. METHODOLOGY/PRINCIPA...
متن کاملA Cytogenetic Study of Heritable Tumors in Nicotiana Species Hybrids.
ENETIC tumors in Nicotiana species hybrids have been reported by several Ginvestigators. These tumors are formed in certain specific hybrid combinations on stems, roots, and occasionally on leaves of all or part of the F, progeny. Since the discovery by KOSTOFF (1930) of nine interspecific tumorous hybrids, almost 20 additional hybrid combinations have been reported in which the entire progeny ...
متن کاملA Partially Fertile Triple Species Hybrid in Nicotiana.
Crosses between three distinct species in Nicotiana are comparatively rare, only nine having appeared in the literature on this genus. The one here reported upon, (rustica Xpaniculata) x Langsdor i , as well as (rustics X Tabacum) Xpaniculata, and (rustica X paniculata) XgZutinosa, was produced in Europe many years ago (EAST 1928) but has not been studied much since. In 1930 KOSTOFF also descri...
