Seasonal expression of apospory in bahiagrass
Tropical Grasslands-Forrajes Tropicales, 2013 Flowering plants can reproduce sexually (outcrossing and/or selfing) and/or asexually. Sexual reproduction implies the successful completion of meiosis and double fertilization for the formation of both the embryo and the endosperm.

Heterosis and Expressivity of Apospory in Tetraploid Bahiagrass Hybrids [PDF]
Crop Science, 2015 ABSTRACTBreeding procedures developed for apomictic species are based on the idea of fixing superior hybrids by apomixis. However, scarce information is available about the occurrence of heterosis in apomictic hybrids. The objective was to generate a group of apomixis‐segregating tetraploid bahiagrass (Paspalum notatum Flüggé) families, evaluate the ...

Micro- and megagametogenesis in Cichorium intybus L.: succes sive stages and some symptoms of apospory [PDF]
Acta Societatis Botanicorum Poloniae, 2014 In Cichorium intybus L., the mode of reproduction could be at the same time sexual and apomicbic. This could explain the contradictions existing in the interpretation of the heritaibidity of the characters in this species.

Hybridity and autopolyploidy increase the expressivity of apospory in diploid Paspalum rufum [PDF]
Plant Systematics and Evolution, 2016 Paspalum rufum Nees is a perennial grass that forms a multiploid complex. Natural populations are composed mainly of diploid (2n = 2x = 20) and tetraploid (2n = 4x = 40) cytotypes.

Cyto-Embryological Analysis of Wild Kentucky Bluegrass Germplasm in Gansu Province, China
Agronomy, 2023 Reproduction studies, particularly embryology, represent basic information of any plant. However, the current embryological information is fragmentary for Kentucky bluegrass (Poa pratensis L.).

Sequence characterization, in silico mapping and cytosine methylation analysis of markers linked to apospory in Paspalum notatum [PDF]
Genetics and Molecular Biology, 2012 In previous studies we reported the identification of several AFLP, RAPD and RFLP molecular markers linked to apospory in Paspalum notatum. The objective of this work was to sequence these markers, obtain their flanking regions by chromosome walking and ...

The Auxin-Response Repressor IAA30 Is Down-Regulated in Reproductive Tissues of Apomictic Paspalum notatum [PDF]
Plants, 2022 The capacity for apomixis in Paspalum notatum is controlled by a single-dominant genomic region, which shows strong synteny to a portion of rice chromosome 12 long arm.

Identification of ovule transcripts from the Apospory-Specific Genomic Region (ASGR)-carrier chromosome [PDF]
BMC Genomics, 2011 Background Apomixis, asexual seed production in plants, holds great potential for agriculture as a means to fix hybrid vigor. Apospory is a form of apomixis where the embryo develops from an unreduced egg that is derived from a somatic nucellar cell, the

A unique life cycle transition in the red seaweed Pyropia yezoensis depends on apospory
Communications Biology, 2019 Plant life cycles consist of two temporally separated stages: a haploid gametophyte and a diploid sporophyte. In plants employing a haploid–diploid sexual life cycle, the transition from sporophyte to gametophyte generally depends on meiosis.

Apospory in Pteris sulcata L. [PDF]
Botanical Gazette, 1919 1. The gametophyte generation of Pteris sulcata L. is ordinarily produced by the germination of a spore. 2. The embryo sporophyte is of apogamous origin. 3.
