Pollen Interference Between Rare and Common Species. [PDF]
Ecol EvolIn a multispecies greenhouse experiment, we performed hand pollination treatments between eight co‐occurring and co‐flowering plant species with varying rarity levels in Switzerland. We found that overall heterospecific pollen interference did not affect seed set nor seed number, used as proxies of recruitment, for neither common nor rare species.

Deep Learning‐Based Classification of Image Data Sets Containing 111 Different Seeds
Advanced Theory and Simulations, Volume 6, Issue 11, November 2023., 2023 A comprehensive database containing 6536 images of 111 seeds from 42 families is created and is publicly available to scientists for further analysis. A custom CNN model is developed and trained using the database. Different activation functions and batch sizes are used to evaluate the performance of the proposed model.

PLANTS, PEOPLE, PLANET, Volume 5, Issue 6, Page 852-858, November 2023., 2023 Herbaria are important tools in botanical documentation for verifying species distribution and past occurrence. In addition to their scientific value, some herbaria, especially those collected by iconic historic figures such as the radical socialist revolutionary Rosa Luxemburg, can increase public interest in plant diversity and conservation by ...

American Journal of Botany, Volume 110, Issue 9, September 2023., 2023 Over 250 non‐native plants arrived on the Atlantic Coast of the United States with pre‐1900s ship ballast, and the authors show which of these species died out (as waifs or short‐lived rarities) and which still persist as local or widespread plants. Abstract Premise Understanding establishment and spread of non‐native plants is important in the face of

Telomerase RNA gene paralogs in plants – the usual pathway to unusual telomeres
New Phytologist, Volume 239, Issue 6, Page 2353-2366, September 2023., 2023 Summary Telomerase, telomeric DNA and associated proteins together represent a complex, finely tuned and functionally conserved mechanism that ensures genome integrity by protecting and maintaining chromosome ends. Changes in its components can threaten an organism's viability.

Weed Research, Volume 63, Issue 4, Page 237-245, August 2023., 2023 Abstract Garlic pennycress (Mummenhoffia alliacea) is a rare weed of the Brassicaceae family, protected in Hungary. In 2021, three new sites of the species were discovered. In addition to these previously unknown occurrences, a detailed study of a roadside occurrence known for a longer time but not yet published was carried out.

Comparative chloroplast genomes and phylogenetic analysis of Aquilegia
Applications in Plant Sciences, Volume 9, Issue 3, March 2021., 2021 Premise Aquilegia is an ideal taxon for studying the evolution of adaptive radiation. Current phylogenies of Aquilegia based on different molecular markers are inconsistent, and therefore a clear and accurate phylogeny remains uncertain. Analyzing the chloroplast genome, with its simple structure and low recombination rate, may help solve this problem.
