Taxonomy and dated molecular phylogeny of Allium oreophilum sensu lato (A. subg. Porphyroprason) uncover a surprising number of cryptic taxa

open access: yesTAXON, Volume 74, Issue 5, Page 1035-1053, October 2025.
Abstract Allium oreophilum, hitherto the representative of the monotypic A. subg. Porphyroprason from the second evolutionary lineage of Allium, is studied in detail. Over about 150 years, A. oreophilum was regarded as a somewhat polymorphous species with two synonyms, all described in the 19th century.

Diversity and life strategies of cyanobacteria and bryophytes within biocrusts in the context of mining tailings disasters in Brazil

open access: yesPlant Biology, Volume 27, Issue 6, Page 1128-1136, October 2025.
Biocrust communities show notable distinctions between sites impacted by mining tailings and unimpacted areas in Brazil, encompassing differences not only in diversity but also in terms of ecological life strategies. Abstract This study investigates the impact of the Fundão Dam rupture in Brazil, one of the most severe industrial disasters globally ...

Observations of PBA-induced Bulbil Production in Onion Inflorescences1

open access: yesHortScience, 1977
Abstract Bulbils were produced in the umbels of onion plants when the bulbs were treated at the time of planting with PBA carried in methyl cellosolve. Methyl cellosolve alone and a PBA-acetone formulation did not induce bulbil formation.

Cryopreservation of garlic bulbil primordia by the droplet-vitrification procedure.

open access: yesCryo letters, 2006
The droplet-vitrification protocol, a combination of droplet-freezing and solution-based vitrification was applied for cryopreserving garlic bulbil primordia. The highest survival and regeneration percentages of cryopreserved primordia (90.1 to 95.0 percent and 82.7 to 85.0 percent, respectively) were achieved after preculture for 2-4 days at 10 degree
