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 کاملThe Nature of Halogen Bonds in [N∙∙∙X∙∙∙N]+ Complexes: A Theoretical Study
The effects of substituents on the symmetry and the nature of halogen bonds in [N∙∙∙X∙∙∙N]+-type systems are presented for the YC5H4N∙∙∙X∙∙∙NC5H5 (Y = NO2, CN, H, CH3, OCH3, OH, NH2, X = Cl, Br, I) complexes. Some structural parameters, energy data and electronic properties were explored with...
متن کاملQuantitative Genetic Interactions. I. Genome Combinations of NICOTIANA LONGIFLORA and N. SANDERAE.
increasing number of contributions to our knowledge of quantitative inA!eritance and polygenic interactions have employed materials and techniques which partition the complex system statistically and experimentally. A major promise is greater understanding of the genetic, cytogenetic, and epigenetic architectures (GRANT 1964) of continuously varying traits. Especially fruitful are methods which...
متن کاملMNDO Study of Nitrogen Atom Inversion in Piperazine, N,N'-Dimethylpiperazine and N,N'-Dichloropiperazine
MNDO semi-empirical SCF MO calculations are used to study the pyramidal nitrogen atom inversion and configurational equilibria in the title compounds.
متن کاملFlower Variegation in Hybrids between NICOTIANA TABACUM and N. OTOPHORA.
HE fate of genes and chromosomes following interspecific gene transfer Tdeserves detailed study. Genes of one species often can be introduced into another without evident changes of their action and with little effect upon their stability. ANDERSON'S (1949) widely known work on introgression after interspecific hybridization could not have been successful had he been dealing with unstable genet...
