Diploid Gynogenesis Induced by Heat Shock after Activation with UV-Irradiated Sperm in Rainbow Trout (Oncorhynchus Mykiss)

Scientific Papers Animal Science and Biotechnologies, 2023
Gynogenesis is a technique used to generate diploid individuals with genetic material exclusively of maternal origin. In this study we test the hypothesis that heat shock treatment of rainbow trout eggs, activated with UV irradiated sperms, leads to the ...

Effect of Media on Gynogenesis Induction in Leek (allium ampeloprasum L.) Breeding Materials

International Journal of Secondary Metabolite, 2014
Leek (Allium ampeloprasum L.) is one of the economically important members of the genus Allium (family:Alliaceae). It is a self-compatible, outbreeding, tetraploid (2n=4X= 32) crop species that is very difficult to improve through traditional breeding ...

Haploid Induction via In vitro Gynogenesis in Tomato (Solanum lycopersicum L.) [PDF]

Journal of Integrative Agriculture, 2014
In order to determine the potential for haploid induction via in vitro gynogenesis in tomato, the ovules and protoplasts of embryo sacs from the hybrids Zhongza 101 and Zhongza 105 were cultured.

GYNOGENESIS INDUCTION IN CULTURE OF UNPOLLINATED OVULES OF PUMPKIN [PDF]

Овощи России, 2011
The perspective of utilization of in vitro culture of unpollinated ovules for development of dihaploid lines of pumpkin is described in the article. The ovules of five hybrids were cultivated on CBM medium. The following combinations of growth regulators

Manipulating Unisexual-Sexual Reproduction Transition to Engineer Genome-Reconstructed Polyploids. [PDF]

Adv Sci (Weinh)
This study developed an efficient approach to generate genome‐reconstructed polyploids involving unisexual gynogenetic Carassius gibelio, sexual C. auratus, and sexual C. cuvieri. The selected superior clone inherited gynogenesis ability of C. gibelio and herpesvirus resistance of wild C.

Transcriptome Profiling Reveals Differences Between Rainbow Trout Eggs with High and Low Potential for Gynogenesis. [PDF]

Genes (Basel)
Background/Objectives: Fish eggs activated with UV-irradiated spermatozoa and exposed to the High Hydrostatic Pressure (HHP) shock to inhibit first cell cleavage develop as gynogenetic Doubled Haploids (DHs) that are fully homozygous individuals.

Spatio-Temporal Patterns of Hybridization in an Alloploid Salamander (Ambystomatidae: Ambystoma) and Conservation Implications of Introgression in a Unisexual Vertebrate. [PDF]

Ecol Evol
Here we investigate a gynogenetic allopolyploid triploid, the Silvery Salamander (LJJ—historically referred to as Ambystoma platineum), an asexual lineage. However, in our focal populations, neither parental species is present, and another sexual host, A. texanum (TT), is a required sperm donor.
