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

open access: yesPlants, 2022
The generation of new hybrid varieties of tomato (Solanum lycopersicum L.) is the most widely used breeding method for this species and requires at least seven self-fertilization cycles to generate stable parent lines. The development of doubled haploids

Sperm specificity and potential paternal effects in gynogenesis in the Amazon Molly (Poecilia formosa) [PDF]

open access: yesPeerJ, 2023
The Amazon Molly (Poecilia formosa) reproduces by gynogenesis, a relatively rare form of asexual reproduction where sperm is required to trigger embryogenesis, but male genes are not incorporated into the genome of the embryo.

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

open access: yesAdv 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.

Application of nuclear technology in maternal inheritance of ship sturgeon (Acipenser nudiventris) [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2022
Induction of Gynogenesis in sturgeon is important, therefore, the aim of this study was gynogenesis inducing in Ship sturgeon Acipenser nudiventris by gamma radiation to the heterologous sperm of Persian sturgeon Acipenser persicus.

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

open access: yesEcol 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.

DIPLOID GYNOGENESIS IN THE MEXICAN AXOLOTL [PDF]

open access: yesGenetics, 1976
ABSTRACT Gynogenetic diploid axolotls were produced by activating eggs with ultraviolet-inactivated sperm, and then subjecting the activated eggs to heat shock. Optimal conditions for ultraviolet inactivation of the sperm, and for suppression of the second meiotic division by heat shock, were established. Gynogenetic diploids produced by

Induction of gynogenesis with ultra-violet irradiated Koi carp (Cyprinus carpio haematopterus) sperm demonstrates the XX/XY sex determination system in Opsariichthys bidens

open access: yesAquaculture Reports, 2022
Opsariichthys bidens (Chinese hooksnout carp) is a small stream fish with high economic value. As the males of this species grow faster than females, it follows that mono-sex breeding has significant potential for commercial production.
