Low Temperature and Polyploidy Result in Larger Cell and Body Size in an Ectothermic Vertebrate
TLDR
The first report on the increase of body mass of a polyploid vertebrate caused by low temperature is shown, and the relationship between increase in cell size and increased body mass is shown.
OPTIMIZATION OF TRIPLOIDY INDUCTION AND GROWTH PERFORMANCE OF Clarias anguillarias (AFRICAN CATFISH) USING COLD SHOCK
TLDR
Triploid hatchlings were obtained from the egg and sperm of Clarias anguillarias fertilized artificially and exposed to cold shock at 50C for 20 minutes, three minutes after fertilization to produce polyploidy.
Effects of Hydrostatic Pressure Treatment of Newly Fertilized Eggs on the Ploidy Level and Karyotype of Pikeperch Sander lucioperca (Linnaeus, 1758)
TLDR
This is the first report that demonstrates the induction of a haplo-triploid karyotype by hydrostatic pressure shock in teleost fish and supports the suitability of the hydro static pressure treatment of freshly fertilized eggs for triploid induction in pikeperch.
Analysis of the gene transcription patterns and DNA methylation characteristics of triploid sea cucumbers (Apostichopus japonicus)
TLDR
The data provide new insights into the epigenetic and transcriptomic alterations of the body wall tissue of triploid sea cucumber and preliminarily elucidate the molecular mechanism of their growth, which is of great significance for the breeding of fine varieties of sea cucumbers.
Comparison of diploid and triploid Carassius auratus provides insights into adaptation to environmental change
TLDR
Compared mRNA and microRNA expressions in liver tissue of diploid and triploid individuals obtained from the Dongting lake water system in central China revealed that changes related to genetic and epigenetic regulation may be caused by abiotic stresses, and facilitate adaptation to environmental changes.
Parámetros Morfométricos de Interés Comercial en Trucha Arcoiris Triploide, Oncorhynchus mykiss
Ejemplares triploides de trucha arcoiris fueron producidos mediante la aplicacion de un choque termico de 13 min de duracion y 27 °C de temperatura a una mezcla de huevas procedentes de tres hembras
Species Means of shock Time at commencement Shock duration Reference Crustaceans Black tiger shrimp , Penaeus monodon Cold shock : 8 ° C
Triploidy, a condition of having 3 sets of chromosomes in the nucleus, occurs naturally in fish. Induction of triploidy is possible by subjecting newly fertilized eggs to sub-lethal treatments prior

STUDIES ON EXPERIMENTAL HAPLOIDY IN SALAMANDER LARVAE
TLDR
In the majority of cases it was impossible to reduce the edematous condition of the larvae with varying concentrations of salt solutions, and two triploid larvae were obtained from punctured eggs, which is the eighth species of amphibian in whichTriploidy has been observed.
INDUCTION OF TRIPLOIDY AND HAPLOIDY IN AXOLOTL EGGS BY COLD TREATMENT
TLDR
Eight of the remaining eight experimental triploids, as well as the single spontaneous triploid, are normal in size, appearance, and viability, and this was also responsible for the high mortality among treated eggs before and during cleavage.
Formation of the Diploid Egg Nucleus Due to Suppression of the Second Maturation Division, Induced by Refrigeration of Fertilized Eggs of the Carp, Cyprinus carpio
TLDR
Refrigeration prevented the second maturation division from going to completion and caused the chromosome duplication in the egg due to a retention of the haploid set of chromosomes normally going into the second polar body, leading to the production of the diploid egg nucleus.
