Under-dominance constrains the evolution of negative autoregulation in diploids [PDF]

open access: yes, 2013
Regulatory networks have evolved to allow gene expression to rapidly track changes in the environment as well as to buffer perturbations and maintain cellular homeostasis in the absence of change.

Exploring Polyploidization in Nigella sativa L.: An Applicable Strategy Towards Crop Improvement

open access: yesHorticulturae
A plant breeding program needs helpful markers, especially morphological ones, which can allow breeders to dispense with other markers, including cytological traits and flow cytometry. These markers can assist plant breeders in distinguishing diploid and

Screening for male fertility status in selected banana genotypes

open access: yesElectronic Journal of Plant Breeding, 2019
In the present study, twenty-five banana cultivars (eight diploids and seventeen triploids) were screened for their male fertility status with reference to the pollen output per anther, pollen size and pollen viability.

Chromosome size-dependent preferential coupling interactions are present in spo11 diploids, not in spo11 zip1 diploids.

open access: yes, 2016
(A-B) Heatmaps of normalized interaction values between non-homologous centromeres in spo11 (A) and spo11 zip1 (B) diploids. Centromeres are arranged from left to right and bottom to top according to their respective chromosome length, from shortest to ...

Targeted generation of polyploids in Hydrangea macrophylla through cross-based breeding

open access: yesBMC Genetics, 2020
Background Up to now, diploid and triploid cultivars were reported for the ornamental crop Hydrangea macrophylla. Especially, the origin of triploids and their crossing behaviors are unknown, but the underlying mechanisms are highly relevant for breeding

Expression Profile Analysis of the Cell Cycle in Diploid and Tetraploid Carassius auratus red var.

open access: yesFrontiers in Genetics, 2020
Polyploidization often leads to “transcriptome shock,” and is considered an important factor in evolution of species. Analysis of the cell cycle, which is associated with survival in polyploidy, has proved useful in investigating polyploidization.

Cytogeography of the East Asian Tulips (Amana, Liliaceae)

open access: yesTaxonomy, 2022
Amana Honda (Liliaceae), known as ‘east Asian tulips’, is a spring ephemeral genus endemic to Sino-Japanese Floristic Subregion, mainly distributed in eastern and central China, Japan and the Korean peninsula. Chromosome numbers are reported here for the

Modelling of gene loss propensity in the pangenomes of three Brassica species suggests different mechanisms between polyploids and diploids [PDF]

open access: yes, 2021
Plant genomes demonstrate significant presence/absence variation (PAV) within a species; however, the factors that lead to this variation have not been studied systematically in Brassica across diploids and polyploids.
