Engineering high-frequency apomixis with normal seed production in hybrid rice

iScience
Summary: Clonal reproduction through seeds, also termed apomixis, has the potential to revolutionize agriculture by allowing hybrid crops to be clonally propagated.

Apomictic Mountain Whitebeam (Sorbus austriaca, Rosaceae) Comprises Several Genetically and Morphologically Divergent Lineages

Biology, 2023
The interplay of polyploidisation, hybridization, and apomixis contributed to the exceptional diversity of Sorbus (Rosaceae), giving rise to a mosaic of genetic and morphological entities.

Measuring maternal line selection driven by differential survival in ex situ collections for plant conservation

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Ex situ plant collections may be increasingly needed to protect representative samples of threatened or rare species and provide plant material for conservation translocation. A primary problem in these ex situ collections is loss of intraspecific variation due to plant death. Different management actions would be required depending on whether

Screening of genome loci associated with gametophyte apomixis at Boechera holboellii plants (Brassicaceae family)

Фактори експериментальної еволюції організмів, 2013
Aims. Apomixis is the seeds-without-sex reproduction of floral plants at which germs in seeds arise from cells of maternal genotype without participation both genetic recombination and syngamy (fusion of male and female gametes).

Coexpression and Transcriptome analyses identify active Apomixis-related genes in Paspalum notatum leaves

BMC Genomics, 2020
Background Paspalum notatum exhibits both sexual and apomictic cytotypes and, thus, is considered a good model for studies of apomixis because it facilitates comparative approaches. In this work, transcriptome sequencing was used to compare contrasting P.

Shrub Encroachment Rewires Microbial Networks to Suppress Soil Organic Carbon Mineralization in Subalpine Meadows

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Shrub encroachment in subalpine meadows reduces soil organic carbon (SOC) mineralization rates and its temperature sensitivity (Q10), particularly in surface soil. This shift is driven by soil acidification, increased stable carbon content, and altered microbial network interactions.

Ecological and evolutionary implications of hybridization, polyploidy and apomixis in angiosperms

Botan‪ical Sciences
Hybridization, polyploidy, and apomixis are related to the diversification of angiosperms, generating complex taxonomic relationships between species. Despite the differences in the frequencies of these phenomena, apomixis, the asexual seed production ...
