Preliminary Identification of Candidate Genes Related to Survival of Gynogenetic Rainbow Trout (Oncorhynchus mykiss) Based on Comparative Transcriptome Analysis

Animals, 2020
In the present research, the eggs from four rainbow trout females were used to provide four groups of gynogenetic doubled haploids (DHs). The quality of the eggs from different clutches was comparable, however, interclutch differences were observed in ...

The effects of sugars and growth regulators on embryo- and callusogenesis in isolated ovules culture of beetroot, Beta vulgaris L. [PDF]

Caspian Journal of Environmental Sciences, 2021
Haploid techniques have risen interest among researchers and breeders as they significantly reduce the time of creating pure lines in breeding programs, especially for biennial vegetable crops.

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

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.

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 ...

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 ...

Evaluation of Growth and Immunological Indices of Allfemale Caspian salmon Salmo trutta caspius Induced by Gamma Irradiation

Brazilian Archives of Biology and Technology, 2022
20 pieces of all-female (produces by using Gynogenesis process via gamma irradiation) Caspian salmon (Salmo trutta caspius) with dosage of 450, 600, 750, 900 and 1050 Gy by gamma irradiation (Co60) with average weight of 2.31 ± 0.22 in a randomized ...

Gene Expression and Antioxidant Characteristics of Rainbow Trout (Oncorhynchus mykiss) Eggs Used for Meiotic Gynogenesis

Fishes
Gynogenesis is a reproductive mode where offspring inherit exclusively maternal chromosomes. Gynogenetic development in fish may be induced intentionally by activating eggs with the UV-irradiated, inactive spermatozoa.
