On the Cytology of Apogamy and Apospory.--II. Preliminary Note on Apospory [PDF]
Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1905 Apospory is the direct vegetative process which leads from the sporophyte to the gametophyte without the intervention of spores. This phenomenon has for a long time been known to occur in mosses and ferns, and several writers have described its morphological characters, but its cytological history has hitherto remained unrecorded.

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.

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. The gametophyte generation of Pteris sulcata under certain conditions was produced aposporously. 4.

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 ...

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.

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

The relation of meiotic behaviour to hybridity, polyploidy and apomixis in the Ranunculus auricomus complex (Ranunculaceae) [PDF]
BMC Plant Biology, 2020 Background Hybridization and polyploidization are powerful evolutionary factors that are associated with manifold developmental changes in plants such as irregular progression of meiosis and sporogenesis.

Apospory appears to accelerate onset of meiosis and sexual embryo sac formation in sorghum ovules
BMC Plant Biology, 2011 Background Genetically unreduced (2n) embryo sacs (ES) form in ovules of gametophytic apomicts, the 2n eggs of which develop into embryos parthenogenetically. In many apomicts, 2n ES form precociously during ovule development.
