Reproduction and BreedingThe aim of this study was to investigate the effects of exogenous estradiol on the expression of the liver–gonadal axis gene in GIFT tilapia. Larval fish (5 dph) were fed a diet with 100 mg kg−1 17α–ethynylestradiol (EE2) for 30 days and then transferred

Transgressivity in Key Functional Traits Rather Than Phenotypic Plasticity Promotes Stress Tolerance in A Hybrid Cordgrass [PDF]
, 2019 Hybridization might promote offspring fitness via a greater tolerance to environmental stressors due to heterosis and higher levels of phenotypic plasticity.

Oikos, EarlyView.Plant functional traits typically show strong covariation, e.g. as in the worldwide leaf economics spectrum (LES). Covariation is thought to arise from selective forces and physical constraints. However, processes shaping covariation at interspecific scales may differ from those at intraspecific scales.

Molecular cytogenetic differentiation of paralogs of Hox paralogs in duplicated and re-diploidized genome of the North American paddlefish (Polyodon spathula). [PDF]
, 2017 BackgroundAcipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species of sturgeons and paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence of ...

The Impact of Polyploid Giant Cancer Cells: The Root of Stress Resilience. [PDF]
Cancer SciAmong the diverse characteristics of polyploid giant cancer cells (PGCCs) observed in various contexts, stress resilience is one of their key features, enabling survival and adaptation under harsh conditions. This review discusses the unique stress tolerance mechanisms of PGCCs and their implications for cancer progression, therapy resistance, and ...

Friends or foes? Polyploidy and competition in a grassland geophyte
Oikos, EarlyView.Previous studies have suggested polyploids may possess a competitive advantage over diploids, due to their larger size, increased vigour or ability to better respond to abiotic stress. However, few studies have tested the effect of polyploidy on competitive ability directly, and only relatively recently has this oversight begun to be addressed. Here we

Loss of redundant gene expression after polyploidization in plants
, 1978 Based on chromosomal location data of genes encoding 28 biochemical systems in allohexaploid wheat,Triticum aestivum L. (genomes AABBDD), it is concluded that the proportions of systems controlled by triplicate, duplicate, and single loci are 57%, 25 ...

Minimum error correction-based haplotype assembly: considerations for long read data
, 2020 The single nucleotide polymorphism (SNP) is the most widely studied type of genetic variation. A haplotype is defined as the sequence of alleles at SNP sites on each haploid chromosome.

FISH-aimed karyotype analysis in Aconitum subgen : aconitum reveals excessive rDNA sites in tetraploid taxa [PDF]
, 2018 The location of 5S and 35S rDNA sequences in chromosomes of four Aconitum subsp. Aconitum species was analyzed after fluorescence in situ hybridization (FISH). Both in diploids (2n = 2x = 16; Aconitum variegatum, A. degenii) and tetraploids (2n = 4× = 32;
