Tolerance to 1 year of drought: The role of seed hydration memory in the germination and early seedling development of Xiquexique gounellei subsp. gounellei under prolonged water deficit

open access: yesPlant Species Biology, Volume 41, Issue 1, January 2026.
This study investigates the impacts of hydration–dehydration cycles (HD cycles) on the germination and early growth of Xiquexique gounellei subsp. gounellei. Our findings demonstrate that HD cycles significantly influence seed germination behavior. However, we observed that memory expression varies according to the plant's life stage.

Historical Temperature Stability and Environmental Drivers Shape Patterns of Phylogenetic Diversity in Cactaceae

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim We aim to investigate the environmental drivers shaping macroecological patterns of phylogenetic structure in plants, using the cactus family (Cactaceae) as a model group. Major Taxa and Location Cactus family (Cactaceae), comprising 1892 species, distributed across the American continent (approximately 42 million km2). Methods We compiled
