The frequency and importance of polyploidy in tropical rainforest tree radiations

New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

Delayed response in a plant-pollinator system to experimental grassland fragmentation [PDF]

, 2018
The fragmentation of natural habitat is considered to be a major threat to biodiversity. Decreasing habitat quality and quantity caused by fragmentation may lead to a disruption of plant-pollinator interactions and to a reduction in sexual reproduction ...

Contemporary hybridization among Arabis floodplain species creates opportunities for adaptation

New Phytologist, Volume 249, Issue 3, Page 1542-1557, February 2026.
Summary Hybridization between closely related species is increasingly recognized as a major source of biodiversity. Yet, whether it can create advantageous trait combinations while purging harmful alleles remains unknown. To address this question, we studied Arabis nemorensis and Arabis sagittata, two endangered species that currently hybridize in a ...

Outcrossing Rates in Pecan and the Potential for Increased Yields

Journal of the American Society for Horticultural Science, 1988
Abstract Nuts produced from controlled crosses of ‘Western’ pecan [ Carya illinoensis (Wangenh.) C. Koch] pollinated with ‘Wichita’ were 20% heavier and 12% larger by volume than self-pollinated nuts.

Genetic Diversity and Population Structure of Sweetpotato Accessions (Ipomoea batatas [L.] Lam.) Revealed by Single Nucleotide Polymorphism Markers

Plant Breeding, Volume 145, Issue 1, Page 85-94, February 2026.
ABSTRACT Use of molecular markers has improved the analysis of genetic variation by eliminating environmental influences on genotype performance. The objective of this study was to assess the genetic diversity (GD) and population structure of 327 sweetpotato genotypes sourced from the major sweetpotato‐growing regions of Zimbabwe and from the ...

The Dark Side of Stress Response: Night Temperature Regimes Drive Distinct Abiotic Pathways in Legumes

Plant, Cell &Environment, Volume 49, Issue 2, Page 925-939, February 2026.
ABSTRACT Global warming increases night temperatures more strongly than day temperatures. Recent evidence indicates that the effect of night temperature on plant physiology is independent of daytime conditions, suggesting distinct stress tolerance mechanisms.

AFLP estimation of the outcrossing rate of Spondias tuberosa (Anacardiaceae), an endemic species to the Brazilian semiarid region

Revista de Biología Tropical, 2013
The umbu tree (Spondias tuberosa) is one of the most important endemic species to the Brazilian tropical semiarid region. The umbu tree has edible fruits with a peculiar flavor that are consumed in natura or in a semi-industrialized form, such as jams ...

Public Policy and Farm-level Strategies for Coexistence in Germany – A Case Study of Bt-maize in Brandenburg [PDF]

The regulatory framework for growing GM crops in Germany comprises quite liberal ex-ante regulations with very strict ex-post liability rules to protect other production forms from possible negative side effects of transgenic plants.

Potential impacts of genetic use restriction technologies (GURTs) on agrobiodiversity and agricultural production systems [PDF]

Development and application of GURT as an appropriation mechanism may potentially have considerable impact on agriculture, the environment and the food security of rural areas in developing countries. Positive impacts may include increased investments in
