Abstract:
The segregation pattern of individuals originating from selfing of several monoembryonic cultivars and one polyembryonic line indicated that polyembryony in mango was of genetic nature. All the plants originating from monoembryonic cultivars bore monoembryonic fruits. A one-monoembryonic to three-polyembryonic segregation pattern was observed among individuals originated from the polyembryonic line, indicating that polyembryony in mango is under the control of a single dominant gene.

The objectives of this work were to evaluate the frequency of polyembryony, and to identify zygotic and nucellar seedlings of Citrus volkameriana using RAPD. Twenty-five polyembryonic and eight monoembryonic seeds were cultivated in vitrofor six months. DNA from seedlings was extracted and used in combination with five RAPD primers to identify zygotic or nucellar origin of the seedlings. Environmental conditions of the year affected significantly (P<0.05) the morphological characteristics of fruitsand the number ofembryos per seed.

Abstract:
Polyembryony is a common trait in most citrus varieties. The level of polyembryony has the potential to be used as a descriptor in the characterization of varieties or to select parents in conventional hybridization work. The aim of this research was to find an efficient methodology to detect, count and estimate the potential number of embryos per seed, the percentage of polyembryonic seeds and the level of polyembryony in the varieties ‘Colimex’ and ‘Lise’ of Mexican lime, and the variety ‘Rosenberger’ of true lemon.

Polyembryony is a trait widely distributed in nature which occurs in different plant species including maize. This trait has been studied at the genetic level with various molecular markers. In the present study we analyzed two monoembryonic and polyembryonic maize groups, derived from the F2population of a cross between plants from a high polyembryonic brachytic (BAP) population and a monoembryonic commercial variety (PUMA). Polymorphism was analyzed among and between these two F2maize groups with AFLPs (amplified fragment length polymorphisms). A total of 16 polymorphic bands were obtained,

Abstract:
Background: Floral sterility and nucellar embryony are peculiar traits of several Citrus species and represent an obstacle to traditional breeding. Morphological sterility mainly results in pistil abortion and anther atrophy, while polyembryony is due to a mechanism known as sporophytic apomixis, which consists of the presence of embryos in the seed generated from the nucellar (maternal) tissue alongside the zygotic embryo (sexual origin). Considering the growing interest in lemon [Citrus limon (L.) Burm. f.] breeding, and the lack of information on floral sterility and the polyembryony trait

Abstract:
The development of polyembryony is a common reproductive strategy in conifers. Multiple embryos are observed during early seed developmental stages. However, upon seed maturation, only the dominant embryo survives, with few exceptions. Although programmed cell death has been reported as the major mechanism responsible for elimination of subordinate embryos, the genetics of surviving embryos and the probabilities of survival remain unclear. The aim of this study is to determine patterns of polyembryony and survival frequency in Araucaria angustifolia (Bert) O. Ktze. Thus, we investigate the mor

Investigations were conducted into aspects of the reproductive biology of the Cyclostomata, a relatively understudied ancient order of bryozoans. Evidence for polyembryony (cloning of sexually produced embryos) in all three major cyclostome clades was obtained using a molecular genetic approach (Chapter 2) confirming historical inferences based on microscopy and supporting the widely held view that this apparently paradoxical reproductive mode characterises the order. The paradoxical nature of polyembryony in the case of cyclostomes was investigated. Genotyping provided evidence for the prolon

Sexual reproduction in plants is the main pathway for the creation of new genetic combinations. In modern agriculture, breeders exploit the genetic diversity generated through sexual reproduction to develop elite cultivars; however, these cultivars require genetic stabiliza
