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

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 ...

A study of the heterochronic sense/antisense RNA representation in florets of sexual and apomictic Paspalum notatum

open access: yesBMC Genomics, 2021
Background Apomixis, an asexual mode of plant reproduction, is a genetically heritable trait evolutionarily related to sexuality, which enables the fixation of heterozygous genetic combinations through the development of maternal seeds.

Greater Thermal Plasticity Toward Heterogeneous Range‐Edge Environments of Three Hypericum Species

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Predictions from the highest‐ranked models testing the effect of range position (RP) and environmental heterogeneity (EH) on trait plasticity, with population‐specific plasticity values in blue (Hypericum montanum), red (H. perforatum), and green (H. maculatum).

Data_Sheet_2_Evolution of an Apomixis-Specific Allele Class in Supernumerary Chromatin of Apomictic Boechera.FASTA

open access: yes, 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 ...

Apomixis in Taraxacum : an embryological and genetic study = Apomixie in Taraxacum : een embryologische en genetische studie

open access: yes, 2001
Apomixis is asexual plant reproduction through seeds that are produced with no prior genome reduction or fertilisation. The use of apomixis holds enormous potential for future plant breeding and production.

Effects of Plant Stress on Facultative Apomixis in Boechera (Brassicaceae)

open access: yes, 2015
In flowering plants, apomixis is asexual reproduction by seeds. Apomixis allows the production of offspring with the same genetic characteristics as the mother plant. Fertilization is not required.

Детекция гемизиготного геномного фрагмента у форм Boechera holboellii (семейство Brassicaceae) с бесполосеменным размножением

open access: yesФактори експериментальної еволюції організмів, 2014
Aims. Apomixis is the clonal reproduction of floral plants by seeds without both meiosis and fertilization. Apomixis has great biotechnological benefits in excess of the gain from the “green revolution” Norman Borlaug.

The Red Queen unveils the sexual and mating strategies of flowers

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Species Assembly Is Lineage Specific: Phylogenetic Divergent Species Aggregate in Some Lineages but Segregate in Others

open access: yesEcology Letters, Volume 29, Issue 5, May 2026.
Phylogenetic relatedness of co‐occurring species is often used as a proxy for inferring prior assembly processes. However, this approach ignores the possibility that different phylogenetic lineages may have evolved distinct assembly processes. Here, we directly observed assembly processes through changes in the co‐occurrence patterns of 1770 pairs of ...
