Emergence of apospory and bypass of meiosis via apomixis after sexual hybridisation and polyploidisation

New Phytologist, 2014
Hybridisation and polyploidy are major forces contributing to plant speciation. Homoploid (2x) and heteroploid (3x) hybrids, however, represent critical stages for evolution due to disturbed meiosis and reduced fertility.

Construction of AFLP-based cosegregation groups of tetraploid Plicatula species and identification of markers linked to apomixis [PDF]

Rodriguésia, 2022
Most species of Plicatula are important native forages. This work aimed to build framework cosegregation groups of the apomictic tetraploid race of Paspalum guenoarum cv. Rojas and localize the locus controlling apomixis in the species.

Variation of Residual Sexuality Rates along Reproductive Development in Apomictic Tetraploids of Paspalum

Plants, 2022
Most apomictic plants are facultative, maintaining the ability to reproduce sexually at different frequencies depending on the taxa, ploidy, and reproductive stage.

Life cycle and morphogenetic differentiation in heteromorphic cell types of a cosmopolitan marine microalga. [PDF]

New Phytol
Summary Gephyrocapsa huxleyi is a prevalent, bloom‐forming phytoplankton species in the oceans. It exhibits a complex haplodiplontic life cycle, featuring a diploid‐calcified phase, a haploid phase and a third ‘decoupled’ phase produced during viral infection. Decoupled cells display a haploid‐like phenotype, but are diploid.
