Chromosomes as Sources of Taxonomic Information for Plant Systematics and Evolution [PDF]

open access: yesTaeckholmia, 2022
Chromosomes are the units of inheritance within the nuclei of all eukaryote cells and carry the genes as DNA packaged in the chromosomes forming the chromatin fibril with histone proteins.

The Many Questions about Mini Chromosomes in Colletotrichum spp.

open access: yesPlants, 2020
Many fungal pathogens carry accessory regions in their genome, which are not required for vegetative fitness. Often, although not always, these regions occur as relatively small chromosomes in different species.

Accessory Chromosome-Acquired Secondary Metabolism in Plant Pathogenic Fungi: The Evolution of Biotrophs Into Host-Specific Pathogens

open access: yesFrontiers in Microbiology, 2021
Accessory chromosomes are strain- or pathotype-specific chromosomes that exist in addition to the core chromosomes of a species and are generally not considered essential to the survival of the organism.

Visualization of chromosome condensation in plants with large chromosomes [PDF]

open access: yesBMC Plant Biology, 2017
Most data concerning chromosome organization have been acquired from studies of a small number of model organisms, the majority of which are mammals. In plants with large genomes, the chromosomes are significantly larger than the animal chromosomes that have been studied to date, and it is possible that chromosome condensation in such plants was ...

Patterns of heterochromatin distribution in plant chromosomes

open access: yesGenetics and Molecular Biology, 2000
The C-band distribution patterns of 105 angiosperm species were compared to identify general patterns or preferential sites for heterochromatin. The base-specific fluorochrome reaction of heterochromatin for 58 of these species and the role played by the

Mapping QTL underlying tuber starch content and plant maturity in tetraploid potato

open access: yesCrop Journal, 2019
Tuber starch content and plant maturity are two important agronomic traits of potato. To investigate the complex genetic basis of these traits in the cultivated potato, as well as the relationship between them, we developed a linkage map in a tetraploid ...
