Regeneration Strategies in Seed Plants: A Continuum Shaping Survival

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Seed plants dominate terrestrial ecosystems in part because regeneration is not a single event, but a coordinated sequence of traits acting across time and space. Here, we synthesize regeneration strategies in seed plants as a continuous, integrated framework spanning pre‐germination regulation, germination timing, seedling emergence, soil seed banking,

A practical guide to species trend detection with unstructured data using local frequency scaling (Frescalo)

Ecography, Volume 2026, Issue 7, July 2026.
Accurately measuring biodiversity change remains a central challenge in ecology. Beyond the general idea of quantifying temporal species frequency changes, several sampling‐related biases in data collection remain key methodological challenges to consider. Long‐term standardized ecological data are rare, and most available datasets exhibit considerable

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

, 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.

Flowcytometric and Allozymic Studies on the Korean Dandelion (Taraxacum, Asteraceae), With Special Reference to the Hybrid Origin of Taraxacum coreanum Nakai

Plant Species Biology, Volume 41, Issue 4, July 2026.
We found that the Korean tetraploid Taraxacum coreanum (Co) shows fixed heterozygosity at two dimeric enzyme loci, sod‐1 (aaab) and mdh‐1 (bddd). Allele‐specific comparisons indicate that sod‐1 ‘a’ and mdh‐1 ‘d’ are characteristic of the triploid T. mongolicum (Mo) whereas the ‘b’ alleles at both loci match Korean diploids (e.g., T. hallaisanense, Ha).

Clonal reproduction by seed of a cultivated hybrid plant: a new perspective for small-scale rice growers

Comptes Rendus Biologies
Transferring an asexual mode of reproduction by seeds (apomixis) to cultivated plants would enable clonal reproduction of heterozygous genotypes such as F1 hybrids with hybrid vigor (heterosis), facilitating their access and multiplication by small-scale

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

Frontiers 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 ...

Could Bowdichia virgilioides Be an Important Ally for Forest Restoration Under Climate Change Scenarios?

Austral Ecology, Volume 51, Issue 7, July 2026.
Conceptual overview of the study. Species distribution models (MaxEnt) were developed using occurrence records and bioclimatic variables to predict the current and future climatic suitability of Bowdichia virgilioides under CMIP6 climate scenarios.

Genotype × Environment Interaction for Leaf Dry Matter Yield in Guineagrass: Identification of Mega‐Environments and Optimization of Multi‐Environment Trials

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Guineagrass (Megathyrsus maximus B.K. Simon & S.W.L. Jacobs [syn. Panicum maximum Jacq.]) presents the highest forage production potential among apomictic cultivated tropical forage grasses in Brazil, and the development of superior cultivars depends on accurate genotype evaluation across multiple environments. This study aimed to characterize

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 ...
