The evolution of apomixis in angiosperms: A reappraisal

, 2012
Apomixis, the asexual reproduction via seed, has long been regarded a blind alley of evolution. This hypothesis was based on the assumption that apomixis is an irreversible, phylogenetically derived trait that would rapidly lead to extinction of the ...

Sex- versus apomixis-specific polymorphisms in the 5′UTR of APOLLO from Boechera shift gene expression from somatic to reproductive tissues in Arabidopsis

Frontiers in Plant Science
IntroductionAmong candidate genes underlying the control components of apomixis, APOLLO is known for its strong linkage to apomeiosis in the genus Boechera.

A pattern of unique embryogenesis occurring via apomixis in Carya cathayensis

, 2012
Apomixis represents an alteration of classical sexual plant reproduction to produce seeds that have essentially clonal embryos. In this report, hickory (Carya cathayensis Sarg.), which is an important oil tree, is identified as a new apomictic species ...

Apomixis in diploid × triploid Tripsacum dactyloides hybrids

, 1991
Apomixis can hinder plant improvement if sexual or apomictic germ plasm of the appropriate ploidy level, required for effective manipulation of apomixis, is not available.

Molecular and embryonic evidence of apomixis in cassava interspecific hybrids (Manihot spp.)

, 1998
In cassava, apomixis could fix hetereozygosity and prevent the transmission of systemic pathogens which complicate vegetative propagation of the crop.

Use of genotyping-by-sequencing to determine the genetic structure in the medicinal plant chamomile, and to identify flowering time and alpha-bisabolol associated SNP-loci by genome-wide association mapping

BMC Genomics, 2017
Background Chamomile (Matricaria recutita L.) has a long history of use in herbal medicine with various applications, and the flower heads contain numerous secondary metabolites which are medicinally active.

Engineering apomixis in plants to stabilize intergenerational hybrid vigor

, 2022
Apomixis is the production of seeds asexually in plants, whereby clonal progeny have an identical genotype as the mother plant (1). In natural apomicts, mechanisms of reproduction are very diverse but carry potential for use in agriculture.

The spread of apomixis and its effect on resident genetic variation

, 2007
In a simulation model we investigated how much of the initial genetic variation that is retained in a population after a dominant mutation has brought apomixis to fixation in it. A marker allele associated with the apomixis mutation is generally retained
