EFFICIENT HAPLOID PRODUCTION ON 'WILKING' MANDARIN BY INDUCED GYNOGENESIS

Acta Horticulturae, 2015
Seedlessness is a major criterion for the citrus fresh fruit market. Therefore, triploid breeding appears very promising for the selection of new citrus cultivars. CIRAD has developed a method to produce triploid hybrids by somatic hybridization between diploid and haploid lines, and demonstrates the potential for haploid citrus production by induced ...

Evidence for feminized genetic males in a flea beetle using newly identified X‐linked markers

Ecology and Evolution, Volume 14, Issue 8, August 2024.
This study investigates the highly female‐biased sex ratio in the flea beetle Altica lythri, examining potential mechanisms such as Wolbachia‐induced feminization of genetic males. Through transcriptomic analysis and the establishment of genotypic sex differentiation markers using the SEX‐DETector approach, we provide evidence that feminization of ...

The paradise fish, an advanced animal model for behavioral genetics and evolutionary developmental biology

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 342, Issue 3, Page 189-199, May 2024.
Paradise fish are air‐breathers, living in hypoxic freshwater environments and displaying complex innate behaviors. To help with gas exchange they have evolved a labyrinth organ which makes them a prime subject for evo‐devo studies, too. Abstract Paradise fish (Macropodus opercularis) is an air‐breathing freshwater fish species with a signature ...

Shoots formation from gynosinesis Cucumis sativus l.

Ho Chi Minh City Open University Journal of Science - Engineering and Technology, 2018
Haploid plants achieve through androgenesis or gynogenesis. In gynogenesis method, the ovary or ovule are used as explants induct haploid plants. Female flower one day before flowering of Cucumis sativus L. are collected.

Maternal ploidy shapes reproductive pathways in the triploid hybrid Chrosomus eos × eos‐neogaeus

Molecular Ecology, Volume 33, Issue 5, March 2024.
Abstract Elements transferred from a mother to her eggs may strongly influence the phenotype of her offspring. Such maternal effects depend on the genotype of the mother, and while multiple ploidy levels occur naturally in some vertebrate species, studies evaluating the impact of maternal ploidy on offspring are scarce. This paper aimed to test whether

Haploid rhapsody: the molecular and cellular orchestra of in vivo haploid induction in plants

New Phytologist, Volume 241, Issue 5, Page 1936-1949, March 2024.
Summary In planta haploid induction (HI), which reduces the chromosome number in the progeny after fertilization, has garnered increasing attention for its significant potential in crop breeding and genetic research. Despite the identification of several natural and synthetic HI systems in different plant species, the molecular and cellular mechanisms ...

Tracking Scientific Gaps in the Conservation of Endangered Sturgeon: A Bibliometric Approach and Content Analyses

Aquaculture Research, Volume 2024, Issue 1, 2024.
The declining sturgeon population has prompted increased efforts for protection and recovery, resulting in its listing on the IUCN Red List of Endangered Species. Conservation and restoration efforts for sturgeon populations are vital within the context of aquaculture.

Induction and Survival of Diploid Gynogenesis With Ultraviolet Light‐Irradiated Sperm in the Manila Clam Ruditapes philippinarum

Aquaculture Research, Volume 2024, Issue 1, 2024.
In order to produce gynogenetic diploid of Manila clam, Ruditapes philippinarum, we studied the optimal conditions of gynogenetic diploid induced by ultraviolet (UV). The irradiance of UV‐induced sperm was 230 μW (cm2·s), and the irradiation time was 0, 3, 6, 9, 12, 15, 18, 21, 24, and 27 s.

Full-Length Transcriptome Reveals Heterologous Sperm Fragments in Natural Gynogenetic Grass Carp

Fishes
Grass carp (Ctenopharyngodon idella) is one of the most economically important cyprinid species cultured in China. The diploid gynogenetic grass carp (2nGGC, 2n = 48) was generated from the hybrid of female grass carp (GC, 2n = 48) and male topmouth ...
