Resistance to frost and tuber soft rot in near-pentaploid Solanum tuberosum - S. commersonii hybrids [PDF]

open access: yes, 2007
The objectives of the present study were to evaluate the tolerance to low temperatures and tuber soft rot in sexual near-pentaploid hybrids between incongruent 2x (1EBN) Solanum commersonii (CMM) and 4x (4EBN) S. tuberosum (TBR). For freezing resistance,

Polyploid lineages in the genus Porphyra [PDF]

open access: yes, 2018
Whole genome duplication is now accepted as an important evolutionary force, but the genetic factors and the life history implications affecting the existence and abundance of polyploid lineages within species are still poorly known.

Leishmania Sexual Reproductive Strategies as Resolved through Computational Methods Designed for Aneuploid Genomes

open access: yesGenes, 2021
A cryptic sexual reproductive cycle in Leishmania has been inferred through population genetic studies revealing the presence of hybrid genotypes in natural isolates, with attempts made to decipher sexual strategies by studying complex chromosomal ...

Epigenetic contribution to successful polyploidizations: variation in global cytosine methylation along an extensive ploidy series in Dianthus broteri (Caryophyllaceae) [PDF]

open access: yes, 2017
Polyploidization is a significant evolutionary force in plants which involves major genomic and genetic changes, frequently regulated by epigenetic factors.

Epigenetic consequences of interploidal hybridisation in synthetic and natural interspecific potato hybrids [PDF]

open access: yes, 2019
Interploidal hybridisation can generate changes in plant chromosome numbers, which might exert effects additional to the expected due to genome merger per se (i.e., genetic, epigenetic and phenotypic novelties).Wild potatoes are suitable to address this ...

The Trypanosoma brucei AIR9-like protein is cytoskeleton-associated and is required for nucleus positioning and accurate cleavage furrow placement [PDF]

open access: yes, 2012
AIR9 is a cytoskeleton-associated protein in Arabidopsis thaliana with roles in cytokinesis and cross wall maturation, and reported homologues in land plants and excavate protists, including trypanosomatids.

p53: Guardian of ploidy

open access: yesMolecular Oncology, 2011
AbstractAneuploidy, often preceded by tetraploidy, is one of the hallmarks of solid tumors. Indeed, both aneuploidy and tetraploidy are oncogenic occurrences that are sufficient to drive neoplastic transformation and cancer progression. True to form, the tumor suppressor p53 obstructs propagation of these dangerous chromosomal events by either ...

Abnormal Action Potentials Associated with the Shaker Complex Locus of Drosophila [PDF]

open access: yes, 1981
Intracellular recordings of action potentials were made from the cervical giant axon in Shaker (Sh) mutants and normal Drosophila. The mutants showed abnormally long delays in repolarization.

Global Analysis of the Small RNA Transcriptome in Different Ploidies and Genomic Combinations of a Vertebrate Complex – The Squalius alburnoides

open access: yesPLoS ONE, 2012
The Squalius alburnoides complex (Steindachner) is one of the most intricate hybrid polyploid systems known in vertebrates. In this complex, the constant switch of the genome composition in consecutive generations, very frequently involving a change on ...

Changes in ploidy affect vascular allometry and hydraulic function in Mangifera indica trees.

open access: yesThe Plant Journal, 2021
The enucleated vascular elements of the xylem and the phloem offer an excellent system to test the effect of ploidy on plant function because variation in vascular geometry has a direct influence on transport efficiency.
