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.

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).

The development of polyembryony is a common reproductive strategy in conifers. Multiple embryos are observed during early seed developmental stages.

ABSTRACT Polyembryony is the differentiation and development of multiple embryos in a single seed. This characteristic can provide advantages, as more than one embryo is produced with the same amount of resources, and the probability of establishment of at least one seedling increases. However, sibling seedlings may also increase competition, affecting development and survival. In the present study, the possible advantages and disadvantages of polyembryony were analyzed in the initial establishment of seedlings of Carapa surinamensis (Meliaceae), a tree species that produces monoembryonic or p

The Mexican Maize Institute, in Saltillo, Northern Mexico, has developed maize populations with polyembryonic traits. Polyembryony (PE) is interesting for at least two reasons: two or more embryos per seed can produce more oil and embryo protein, as well as savings in the number of seeds necessary to reach a certain population per unit area. The founding population (established in 1973) had 1.5% of PE, identified as "twin plants" by seed. Starting in 1975 different recurrent selection schemes have been applied in order to increase the PE frequency. By 1991 the selection response placed PE at 4

In Drosophila melanogaster, the syncytium is considered essential for establishing the morphogenetic gradients that initiate segmental patterning. However, we found that de

Abstract:
In conifers, polyembryony (multiple embryos within an ovule) may decrease the number of seeds lost to random embryo abortion, and (or) increase the proportion of outcrossed seeds if outcrossed embryos out-compete selfed ones. Western redcedar (Thuja plicata Don ex D. Donn, Cupressaceae) is a conifer with a mixed (selfed and outcrossed) mating system and high self-fertility with simple (archegonial) polyembryony. To test whether polyembryony can decrease seed abortion or the proportion of selfed seedlings, we conducted controlled pollinations in a seed orchard in southwestern British Columbia.

Abstract:
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. Polyembryony limits the use of seed parents in scion breeding programs, and the recovery of monoembryonic hybrids to be used as female parents is a crucial pre-breeding component. The objectives of this work were the identification of SNPs closely linked with the genes implied in these traits for marker-assisted selection. Genotyping by sequencin

Abstract:
Lecythis pisonis produces edible seeds rich in nutritional and functional elements such as selenium and are a great alternative to Brazilian nuts. The seeds have low germination, which may be related to physical dormancy imposed by tegument, meaning that polyembryonic seedlings can be a strategy to increase final stand. The objective of this work was to study methods to overcome seed dormancy and auxin induction in polyembryonic seedlings of pisonis. The experiment to break dormancy consisted of seven treatments: T1: intact seeds; T2: seeds scarified on hilum’s opposite side; T3: seeds scarifi

Mango is a commercial fruit crop in different parts of the tropical and subtropical world. Commercially important monoembryonic varieties are propagated through grafting onto rootstock seedlings of polyembryonic genotypes that plays an important role in sustained growth and production. Use of salt tolerant genotypes as rootstock to combat the adverse effect of salinity could be helpful for commercial mango production in salt affected areas. Current study was carried out to elucidate the effect of salinity stress induced by NaCl + CaCl2 (1:1 w/w) at 0, 25, 50 and 100 mM concentrations in irriga

In mango, leaf and fruit volatile aroma profiles are variety specific which can be used as fingerprint of a variety. Such biochemical markers can also discriminate the nucellar and zygotic seedlings in polyembryonic mango varieties. In order to validate the applicability of volatile as well as phenolic acid profiles as biomarkers, the open pollinated seedlings of three polyembryonic varieties of mango were compared with their mother trees. Leaf volatile and phenol acid profiling were done using Gas Chromatography/Mass Spectrometry (GCMS) and Liquid Chromatography/Mass Spectrometry (LCMS) metho

Abstract: The polyembryony rate is a very important factor to consider when choosing a commercial rootstock. Currently, automated systems are used to improve seed quality analyses. X-ray testing is a fast, simple, non-destructive, high-precision test that allows to examine in detail the internal morphology of the seeds to identify damaged areas, their location and types of damage. In this context, the present research aimed to verify the possibility of using X-ray test to evaluate the polyembryony in Swingle citrumelo seeds.

The seeds display anemocoric dispersion. Germination assays showed that recently collected seeds have higher rates of germination (79.3%). Polyembryony was recorded for the first time for the genus Anemopaegma. Seedlings were not found in the natural habitat.

Abstract:
Megasporogenesis and megagametogenesis were examined in a male-sterile, female-fertile mutant (ms1) of soybean (Glycine max (L.) Merr.). Multinucleate (more than eight) megagametophytes resulted from failure of postmeiotic cytokinesis that leads to a coenomegaspore of four haploid nuclei. Fusion of some nuclei may occur. Subsequent development results in mature megagametophytes with up to four eggs, or often abortion. These results support field data that show the male-sterile ms1 gene is associated with increased frequencies of polyembryony, polyploidy, haploidy, and reduced female fertility.
