Genetic Variability and Selection of Doubled Haploid Lines of Eggplant (Solanum melongena L.) Obtained from Anther Culture

Agriculture
Genetic variability is essential for accelerating the selection of high-yield varieties. Therefore, this study aims to evaluate the genetic variability and agronomic performance of eggplant doubled haploid obtained through anther culture.

Detecting Salt Tolerance in Doubled Haploid Wheat Lines

Agronomy, 2019
Improving salt tolerance of genotypes requires a source of genetic variation and multiple accurate selection criteria for discriminating their salt tolerance.

Ploidy‐Dependent Response to Anticancer Drugs of Human Embryonic Stem Cells

Cell Proliferation, EarlyView.
Using isogenic hESCs, differing only in their ploidy level, we show the effect of ploidy on the resistance to anticancer drugs. We demonstrate that polyploidy, by itself, confers sensitivity to chemotherapies, leading to higher apoptosis and delayed proliferation, while the loss of p53 reverses the phenotype, demonstrating higher resistance.

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

The FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.

Haploid and Doubled Haploid Platforms for Wheat Improvement: Methods and Applications

Agronomy
Haploid and doubled haploid (DH) technologies are important tools for accelerated wheat (Triticum aestivum L.) breeding, enabling the rapid production of fully homozygous lines and increasing the efficiency of genetic analysis of complex traits.

Genome‐scale evidence for host‐associated lineage divergence in the parasitoid, Microctonus aethiopoides

Insect Molecular Biology, EarlyView.
Host associations are primary drivers of genomic divergence, with clear phylogenetic separation observed between strains associated with Hypera and Sitona weevil hosts. Genomic diversity aligns with reproductive modes: sexually reproducing ancestral lineages maintain high heterozygosity, while derived asexual strains exhibit reduced heterozygosity and ...

Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

Journal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

Influence of different wheat and Imperata cylindrica genetic backgrounds on haploid induction efficiency in wheat doubled haploid breeding

Czech Journal of Genetics and Plant Breeding, 2014
Four Indian and one Japanese accession of Imperata cylindrica were assessed for their influence upon haploid production in F1 generations of 21 wheat crosses (winter × spring, spring × spring and winter × winter) to find an efficient pollen source for ...

Diallelic Analysis of Tropical Maize Germplasm Response to Spontaneous Chromosomal Doubling

Plants, 2020
Chromosome doubling is an important step in the production of maize doubled haploid (DH) lines to induce fertility in the male and female reproductive organs of haploid plants.

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.
