Reproductive Barriers and Genomic Hotspots of Adaptation During Allopatric Species Divergence
Molecular Ecology, Volume 34, Issue 21, November 2025.ABSTRACT Theory predicts that in allopatric populations, genomic divergence and reproductive barriers may be driven by random genetic drift and thereby evolve slowly in large populations. However, local adaptation and divergence under selection may also play important roles, which remain poorly characterised.

Pharmacologically Induced Meiosis Apomeiosis Interconversions in \u3ci\u3eBoechera\u3c/i\u3e, \u3ci\u3eArabidopsis\u3c/i\u3e and \u3ci\u3eVigna\u3c/i\u3e [PDF]
, 2018 Apomixis is a clonal propagation method that produces offspring identical to the mother plant. With this feature, superior traits could be maintained over generations. However, our knowledge about apomixis is limited.

Influences of plant maternal effects, chemotype, and environment on the leaf bacterial community
Plant Biology, Volume 27, Issue 5, Page 903-912, August 2025.Plant maternal effects and growth environment, rather than terpenoid chemotype, determine the leaf microbial community of Tanacetum vulgare, but specific terpenoids are correlated with the abundance of certain bacteria. Abstract Plant individuals within a species can differ markedly in their leaf chemical composition, forming so‐called chemotypes ...

Ecology and Evolution, Volume 15, Issue 7, July 2025.Strong ecological gradients along heterogeneous environments play an important role in shaping population differentiation across species ranges. We investigated the spatial variability of biological responses in the intertidal bivalve Mytilus californianus to highlight the costs and trade‐offs of local adaptation and phenotypic plasticity across ...

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.

Costs of reproduction in flowering plants
New Phytologist, Volume 247, Issue 1, Page 55-70, July 2025.Summary Costs of reproduction arise when investments into current reproduction reduce future reproductive fitness. Studies on reproductive costs use diverse approaches, including the analysis of gene expression, physiology, trade‐offs between reproduction and growth/survival, and the impact of reproductive investments on population growth.

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

The Roles of Epigenetics in the Interplay Between Beneficial Rhizobacteria and Plants
Modern Agriculture, Volume 3, Issue 1, June 2025.The activity of PGPR in soil enhances the availability of nutrients and hormones secreted by these PGPRs, while nutrients acquired from PGPR‐enriched soil induce epigenetic modifications in plants. These altered epigenetic marks subsequently regulate plant gene expression patterns, including those involved in metabolite synthesis (such as root exudates)

Deciphering the adjustment between environment and life history in annuals: lessons from a geographically-explicit approach in Arabidopsis thaliana [PDF]
, 2014 The role that different life-history traits may have in the process of adaptation caused by divergent selection can be assessed by using extensive collections of geographically-explicit populations.

MHC Diversity Across Time and Space
Ecology and Evolution, Volume 15, Issue 4, April 2025.The article discusses the importance of genetic diversity, particularly in the Major Histocompatibility Complex (MHC) loci, in maintaining evolution and protecting against infectious disease. We review the emerging research on geographic and temporal patterns of MHC diversity in natural populations and highlight the consequences of lower MHC diversity ...
