GWAS identifies a polyembryony locus in mango: development of KASP and PACE markers for marker-assisted breeding [PDF]

Frontiers in Plant Science
Apomixis is a horticultural trait that enables clonal propagation of hybrids by producing asexual embryos from maternal cells in the ovule without meiosis.

Genotyping by Sequencing for SNP-Based Linkage Analysis and the Development of KASPar Markers for Male Sterility and Polyembryony in Citrus [PDF]

Plants, 2023
Polyembryony and male sterility (MS) are essential characters for citrus breeding. MS, coupled with parthenocarpy, allows for addressing the diversification of diploid seedless mandarin varieties, and nucleocytoplasmic MS is the most prevalent system ...

Phylogenetically Widespread Polyembryony in Cyclostome Bryozoans and the Protracted Asynchronous Release of Clonal Brood-Mates. [PDF]

PLoS ONE, 2017
Polyembryony-the production of multiple cloned embryos from a single fertilised egg-is a seemingly paradoxical combination of reproductive modes that nevertheless persists in diverse taxa. We document features of polyembryony in the Cyclostomata (Bryozoa)

Evolution of polyembryony: Consequences to the fitness of mother and offspring [PDF]

Journal of Genetics, 1991
Polyembryony, referring here to situations where a nucellar embryo is formed along with the zygotic embryo, has different consequences for the fitness of the maternal parent and offspring.

Promoter insertion leads to polyembryony in mango - a case of convergent evolution with citrus. [PDF]

Hortic Res, 2023
Sexual reproduction in plants is the main pathway for creating new genetic combinations in modern agriculture. In heterozygous plants, after the identification of a plant with desired traits, vegetative propagation (cloning) is the primary path to create

First evidence of polyembryony in black mangrove Avicennia germinans

Botanica Marina, 2022
We provide the first documented case of the black mangrove, Avicennia germinans, producing multiple seedlings from a single propagule, a phenomenon called polyembryony, on several occasions.

A chromosome-level genome assembly of the polyembryonic endoparasitoid Macrocentrus cingulum [PDF]

Scientific Data
Polyembryony is a unique reproductive pattern, where multiple genetically identical offspring develop from a single egg. Macrocentrus cingulum, a polyembryonic endoparasitoid, is one of the dominant parasitoids of the globally agricultural pest, Ostrinia

Polyembryony in angiospermous trees of the Brazilian Cerrado and Caatinga vegetation

Acta Botânica Brasílica, 2001
The occurrence of polyembryony was investigated in 75 woody species of the Cerrado in central Brazil and the xerophilous Caatinga vegetation in northeastern Brazil.

Polyembryonic or Apomictic Seeds Enable Fig Trees to Establish New Populations Without Their Pollinating Wasps, a Case Observation in <i>Ficus gasparriniana</i>. [PDF]

Ecol Evol
Development of apomictic adventitious embry o in Ficus gasparriniana. Apomixis is a key reproductive strategy for F. gasparriniana, especially when pollination by fig wasps is limited. In the absence of pollination, F. gasparriniana produces seeds through adventitious embryos formed within the nucellar tissue, which is accompanied by polyploidization ...

Two's company: Monozygotic twinning in the small-spotted catshark (Scyliorhinus canicula). [PDF]

J Fish Biol
Abstract Developmental abnormalities in elasmobranchs (sharks and rays) are rarely documented, with reported cases primarily involving fin or cranial deformities. Monozygotic twinning, the formation of identical twins from a single zygote, is particularly rare in these species and has been observed overwhelmingly in viviparous elasmobranchs.
