Surviving the Storm: The Role of Poly‐ and Depolyploidization in Tissues and Tumors

Advanced Science
Polyploidization and depolyploidization are critical processes in the normal development and tissue homeostasis of diploid organisms. Recent investigations have revealed that polyaneuploid cancer cells (PACCs) exploit this ploidy variation as a survival ...

Red rot disease resistance in interspecific hybrids of sugarcane derived from diverse cytotypes of Saccharum spontaneum L.

Journal of Sugarcane Research
Red rot disease has caused major loss to sugarcane crops for more than a hundred years.  It  is caused by the fungal pathogen Colletotrichum falcatum Went.

The chromosome number and heterochromatin distribution pattern suggest differentiation among species of the Stylosanthes scabra-seabrana complex [PDF]

Anais da Academia Brasileira de Ciências
The genus Stylosanthes has economic importance in semi-arid regions and requires studies that reveal complex relationships between species involving different ploidies.

Variance of ploidy in Candida albicans [PDF]

Journal of Bacteriology, 1982
Determination of ploidy was performed on isolates of Candida albicans from clinical sources by measuring nuclear DNA content with fluorescent microscope photometry. By this criterion and UV irradiation survival experiments, haploid, diploid, and tetraploid strains were identified in this organism.

Genome size variation and polyploidy incidence in the alpine flora from Spain

Anales del Jardín Botánico de Madrid, 2013
The interest to study genome evolution, in particular genome size variation and polyploid incidence, has increased in recent years. Still, only a few studies have been focused at a community level.

Karyotype, ploidy, and gene dosage [PDF]

WormBook, 2005
The normal karyotype of Caenorhabditis elegans, with its five pairs of autosomes and single pair of X chromosomes, is described. General features of chromosomes and global differences between different chromosomal regions are discussed. Abnormal karyotypes, including duplications, deficiencies, inversions, translocations and chromosome fusions are ...

Parental ploidy strongly affects offspring fitness in heteroploid crosses among three cytotypes of autopolyploid Jacobaea carniolica (Asteraceae).

PLoS ONE, 2013
Reproductive interactions among cytotypes in their contact zones determine whether these cytotypes can co-exist and form stable contact zones or not. In autopolyploids, heteroploid cross-compatibilities might depend on parental ploidy, but tests of this ...

Enhanced sugar accumulation and regulated plant hormone signalling genes contribute to cold tolerance in hypoploid Saccharum spontaneum

BMC Genomics, 2020
Background Wild sugarcane Saccharum spontaneum plants vary in ploidy, which complicates the utilization of its germplasm in sugarcane breeding. Investigations on cold tolerance in relation to different ploidies in S.

In Vivo Fast Induction of Homogeneous Autopolyploids via Callus in Sour Jujube (Ziziphus acidojujuba Cheng et Liu)

Horticultural Plant Journal, 2016
Polyploidization has been demonstrated as a very effective approach in fruit tree improvement. Sour jujube (Ziziphus acidojujuba Cheng et Liu) is a promising diploid wild, traditional fruit species (2n = 2x = 24) that is rich in vitamin C, which is the ...
