A Full-Length Reference Floral Transcriptome of Boehmeria tricuspis Provides Insights into Apomeiosis and Polyploidy [PDF]

open access: yesInternational Journal of Genomics, 2019
Boehmeria tricuspis (Hance) Makino constitutes a hardy herbaceous or shrubby perennial native to East Asia that includes different ploidy levels and reproductive modes (diplosporous to sexual).

Asexual thalli originated from sporophytic thalli via apomeiosis in the green seaweed Ulva [PDF]

open access: yesScientific Reports, 2019
AbstractApomixis is an asexual reproduction system without fertilization, which is an important proliferation strategy for plants and algae. Here, we report on the apomeiosis in the green seaweed Ulva prolifera, which has sexual and obligate asexual populations.

Partitioning Apomixis Components to Understand and Utilize Gametophytic Apomixis [PDF]

open access: yesFrontiers in Plant Science, 2019
Apomixis is a method of reproduction to generate clonal seeds and offers tremendous potential to fix heterozygosity and hybrid vigor. The process of apomictic seed development is complex and comprises three distinct components, viz., apomeiosis (leading ...

Apospory and Diplospory in Diploid Boechera (Brassicaceae) May Facilitate Speciation by Recombination-Driven Apomixis-to-Sex Reversals [PDF]

open access: yesFrontiers in Plant Science, 2019
Apomixis (asexual seed formation) in angiosperms occurs either sporophytically, through adventitious embryony, or gametophytically, where an unreduced female gametophyte (embryo sac) forms and produces an unreduced egg that develops into an embryo ...

Inheritance of apomeiosis (diplospory) in fleabanes (Erigeron, Asteraceae) [PDF]

open access: yesHeredity, 2004
Unreduced egg formation (apomeiosis) in flowering plants is rare except when it is coupled with parthenogenesis to yield gametophytic apomixis via apospory or diplospory. Results from genetic mapping studies in diverse apomictic taxa suggest that apomeiosis and parthenogenesis are genetically linked, a finding that is compatible with the conventional ...

A sexual/apomictic consensus linkage map of Eragrostis curvula at tetraploid level [PDF]

open access: yesBMC Plant Biology
Background Apomixis is an asexual reproduction process that allows plants to bypass meiosis and fertilization, resulting in clonal seeds that are genetically identical to the maternal genotype.

Apomeiosis inAcinetospora (phaeophyceae, ectocarpales) [PDF]

open access: yesHelgol√§nder Meeresuntersuchungen, 1986
Acinetospora crinita from the Mediterranean Sea has been studied in laboratory cultures. The plants formed monospores and unilocular sporangia. Both monospores and zoids from unilocular sporangia developed to new plants with the same habitus and chromosome number (average ca 47).

Evolution of an Apomixis-Specific Allele Class in Supernumerary Chromatin of Apomictic Boechera [PDF]

open access: yesFrontiers in Plant Science, 2022
Asexual reproduction through seeds in plants (i.e., apomixis) is a heritable trait, and apomixis- linked loci have been identified in multiple species. However, direct identification of genomic elements is typically hindered as apomixis-linked loci and ...

Phylogenomics identifies parents of naturally occurring tetraploid bananas [PDF]

open access: yesBotanical Studies
Background Triploid bananas are almost sterile. However, we succeeded in harvesting seeds from two edible triploid banana individuals (Genotype: ABB) in our conservation repository where various wild diploid bananas were also grown.

Synthetic Apomeiosis in Tomato via the Mutagenesis of SlSPO11-1, SlREC8, and SlTAM to Engineer Mitosis Instead of Meiosis

open access: yesMethods in Molecular Biology
Abstract Heterosis, or hybrid vigor, is a crucial driver of yield and robustness in modern hybrid breeding. However, F1 hybrid plants give rise to genetically variable F2 offspring due to the segregation of genetic material in male and female meiosis.
