Cytology and chromosome numbers of some Czechoslovak roses III
TLDR
The somatic association of rose chromosomes is discussed in connection with mitotic peculiarities of Rosa pimpinellifolia R 316 and a new species Rosa popekiiKlášterský is described.
La variation somatique et l'évolution chez les plantes supérieures
TLDR
It is concluded that somatic development plays two roles: it acts as a filter or as an amplifier of the relative number of mutant gametes produced, and these developmental effects are associated with the modes of dispersal of pollen and seeds, they could well explain how Angiosperms have so rapidly radiated and evolved.
Arrangement of chromosomes in the interphase nucleus of plants
TLDR
Evidence is presented indicating that, in common wheat, the gene system that determines the specific pattern of chromosomal arrangement in the nucleus is operating via the microtubular elements of the spindle system.
Molecular phylogeny of Gossypium species by DNA fingerprinting
TLDR
The level of variation detected in closely related genotypes by RAPD analysis indicates that it may be a more efficient marker than morphological marker, isozyme and RFLP technology for the construction of genetic linkage maps.
CLONAL ANALYSIS OF LEAF DEVELOPMENT IN
TLDR
There is a slight gradient in the duration of cell division along the length of of the lamina late in development, with cell division ceasing progressively from the lamination tip to the base over two cell cycles.
Clonal analysis of leaf development in cotton.
TLDR
The parameters of cell division in cotton are similar to those described for tobacco with the notable exception of the behavior of cells at the leaf margin.
Somatic crossing-over in Antirrhinum majus
TLDR
The use of precise precursors in the biosynthetic pathway to anthocyanidin formation provided confirmatory evidence for the identification of the genes involved in the somatic aberrations.
COMPARISONS OF SOMATIC CROSSING OVER FREQUENCY IN NICOTIANA TABACUM AND THREE OTHER CROP SPECIES
TLDR
Tobacco is compared with Glycine max, Gossypium barbadense, and Lycopersicon esculentum and a greater number of D spots than of A spots is observed in tobacco.
