Parent-of-Origin Effects on Seed Size Modify Heterosis Responses in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2022
Parent-of-origin effects arise when a phenotype depends on whether it is inherited maternally or paternally. Parent-of-origin effects can exert a strong influence on F1 seed size in flowering plants, an important agronomic and life-history trait that can

Effects of Donor x Inducer Interaction on the Success of Haploid Induction and Comparison of Haploid Seed Identification Methods in the In vivo Maternal Haploid Technique in Maize

open access: yesJournal of Agricultural Sciences, 2022
This study was conducted to investigate the effect of donor and inducer lines on the haploid induction rate in the in vivo maternal doubled haploid technique in maize and to compare the methods used in haploid seed separation.

Interspecific hybridization of sturgeon species affects differently their gonadal development

open access: yesCzech Journal of Animal Science, 2018
Gonad development in fish is generally assumed to be negatively influenced by interspecific hybridization, resulting in sterility or sub-sterility. However, this is not the case in sturgeons (Acipenseridae), in which fertile hybrids are common.

A Target Capture-Based Method to Estimate Ploidy From Herbarium Specimens

open access: yesFrontiers in Plant Science, 2019
Whole genome duplication (WGD) events are common in many plant lineages, but the ploidy status and possible occurrence of intraspecific ploidy variation are unknown for most species.

Embryos Arising from Apronuclear (0PN) and Unipronuclear (1PN) Have Similar Euploidy Rates with Those from 2PN and Should be Considered for Transfer

open access: yesFertility & Reproduction, 2019
Background: Fertilisation assessment is routinely made at 16–18 hours post-ICSI and 18–20 hours post-insemination. However, the absence of pronuclei (PN) during standard fertilisation assessment does not necessarily indicate fertilisation failure.

Diâmetro dos grãos de pólen e tamanho dos estômatos em acessos diplóides e tetraplóides de Hemarthria altissima (Poiret) Stapf & Hubbard (Gramineae) Pollen grain diameter and stomatal size in diploid and tetraploid accessions of Hemarthria altissima (Poiret) Stapf & Hubbard (Gramineae)

open access: yesCiência Rural, 1999
Sete acessos da gramínea forrageira Hemarthria altissima, diplóides e tetraplóides africanos e tetraplóides brasileiros, foram analisados com fins de caracterizar, nos diferentes níveis de ploidia, os parâmetros diâmetro dos grãos de pólen e tamanho dos ...

Human megakaryocyte ploidy.

open access: yesHistology and histopathology, 1999
We reviewed the literature concerning the history of determination of the ploidy of human megakaryocytes and its relationship with diseases. The ploidy of rabbit megakaryocytes was analyzed by microspectrophotometry in 1964, and the analysis of the ploidy in human megakaryocytes was first performed in 1968. Presently, microphotometry and flow cytometry

Higher ploidy coincides with inferior performance and no difference in drought tolerance in a mesocosm experiment with common reed (Phragmites australis)

open access: yesEnvironmental and Experimental Botany
Climate change leads to more extreme weather events. Therefore, high stress tolerance is becoming increasingly critical for plants. A higher ploidy level has been reported to lead to higher stress tolerance in plants.

Problems associated with the use of Heliantbus species for the breeding of the cultivated sunflower: Ploidy level or phylogenetic distance? [PDF]

open access: yesSelekcija i Semenarstvo, 2000
Of the 49 species that comprise the genus Helianthus, 42 are present in the wild species collection at the Institute of Field and Vegetable Crops. This is a rich bank of desirable genes for sunflower breeders.
