Biology, 2022 Teleost fishes exhibit extraordinary diversity, plasticity and adaptability with their sex determination and sexual development, and there is growing evidence that non-coding RNAs (ncRNAs) are emerging as critical regulators of reproduction.

In vitro gynogenesis in red beet (Beta vulgaris L.): effects of ovule culture conditions
Acta Societatis Botanicorum Poloniae, 2014 In this paper the influence of factors affecting gynogenic response of red beet ovules is discussed. The ovule response frequencies were the highest in the following conditions: N6 (Chu 1975) mineral salts, 0.5 mg/l IAA, 0.2 mg/l BA, 27 or 32oC.

Studies on Gynogenesis Induction in Cassava (Manihot esculenta Crantz) Unpollinated Ovule Culture
Frontiers in Plant Science, 2020 Cassava (Manihot esculenta Crantz) is an important crop for subsistence farming in tropical and subtropical regions. There is a need to increase the rate of genetic gain to develop varieties adapted to new environmental conditions affected by climate ...

Ecology and Evolution, Volume 16, Issue 7, July 2026.Sturgeons are an important species due to their complex genetic structure and evolutionary characteristics. Unfortunately, they are threatened with extinction due to illegal and overfishing, as well as the loss of their natural habitats. In our work, we examine the genetic diversity of four sturgeon species that inhabit the Black Sea basin and its ...

BioEssays, Volume 48, Issue 6, June 2026.Zebrafish illustrates how polygenic sex determination, maternal germline bottlenecks, and a structurally restless genome jointly destabilize deep homozygosity. These interlocking constraints make fully isogenic zebrafish lines effectively unattainable, turning this model into a natural “stress test” for assumptions about genetic background and ...

Evaluation of genetic stability of sugar beet (Beta vulgaris L.) plants obtained from unfertilized ovules using RAPD markers [PDF]
Journal of Central European Agriculture, 2019 In order to improve the methods of embryo regeneration applied so far in in vitro cultures, a two-phased, innovative method was used. It involved using a liquid and solid media.

Molecular Ecology, Volume 35, Issue 2, January 2026.ABSTRACT Parthenogenesis, or all‐female clonal reproduction, is rare among vertebrates. This is often attributed to the selective disadvantages of assumed reduction of genetic diversity in the absence of sex. However, parthenogenetic vertebrates have highly complex evolutionary histories, with most arising through hybridisation and many being polyploid.

Macro‐Hybrid and Micro‐Hybrid of Fish
Reviews in Aquaculture, Volume 18, Issue 1, January 2026.ABSTRACT This study reviews the progress in fish breeding, focusing on distant hybridization and gynogenesis, and introduces the theory of macro‐hybrid and micro‐hybrid. The macro‐hybrid refers to the allo‐progeny derived from distant hybridization, including the allo‐progenies.

Aquaculture Research, Volume 2026, Issue 1, 2026.To optimize all‐female production in marbled flounder (Pseudopleuronectes yokohamae), a species with marked female‐biased growth, hormonal induction of pseudomales using 17α‐methyltestosterone (MT) is essential. However, its impact on somatic growth is dose‐dependent, and the underlying mechanisms remain poorly understood.
