Chromosome segregation in plant meiosis [PDF]

Frontiers in Plant Science, 2014
Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

Genetic and karyotype divergence between parents affect clonality and sterility in hybrids [PDF]

eLife, 2023
Asexual reproduction can be triggered by interspecific hybridization, but its emergence is supposedly rare, relying on exceptional combinations of suitable genomes.

RNA-seq analyses on gametogenic tissues of alfalfa (Medicago sativa) revealed plant reproduction- and ploidy-related genes [PDF]

BMC Plant Biology
Background In alfalfa (Medicago sativa), the coexistence of interfertile subspecies (i.e. sativa, falcata and coerulea) characterized by different ploidy levels (diploidy and tetraploidy) and the occurrence of meiotic mutants capable of producing ...

Genetic composition and heterozygosity of gibberellin-induced 2n gametes evaluated by SSR markers in Populus [PDF]

BMC Plant Biology
Background The artificial induction of unreduced (2n) gametes, due to first division restitution (FDR) or second division restitution (SDR), is an important method to produce triploids in higher plants.
