Tropical forests across the globe are facing intensifying droughts, yet their responses are far from uniform. We argue that this variability should be understood in the context of interacting legacies across scales. At the continental scale, evolutionary history and past climatic filters have left distinct imprints on forest composition. At landscape scale, edaphic and hydrological heterogeneity constrain species distributions and functional strategies. These legacies converge in the functional trait space available to tree communities, shaping their resilience or vulnerability to novel drought regimes. By placing drought in this biogeographic, edaphic, and trait-based context, we highlight the importance of integrating historical and environmental filters into predictive models of tropical forest futures.

Soil salinization poses a growing threat to global agriculture, prompting efforts to enhance plant salt tolerance. Recretohalophytes, such as Limonium bicolor, have evolved salt glands – specialized epidermal structures that actively secrete excess salt to survive in saline environments. A recent study identified the importin-β protein LbSAD2 as a key regulator of salt gland development, acting via interaction with Lb2G12567, and repressed by Lb2G12077. Functional studies confirmed that this regulatory module enhances both gland density and salinity tolerance. Comparative insights from Arabidopsis reveal that SAD2-mediated nuclear transport integrates stress and developmental signalling. This reveals the emerging molecular framework linking nuclear transport to epidermal specialization in halophytes, and outlines future directions to explore the evolutionary conservation and biotechnological potential of LbSAD2-mediated salt gland regulation.

Understanding the physiological and molecular mechanisms by which plants adapt to environmental factors is essential for improving crop production and protecting biodiversity amid rapid anthropogenic climate change. The Cleomaceae is a family that stands out for its potential to study areas including floral diversity, species richness, and C4 photosynthesis. Its close relationship to the Brassicaceae allows for comparisons with Arabidopsis thaliana, which will lead to new knowledge that can be transferred to other species, including crops. This proximity paves the way for the investigation of monosymmetric and polysymmetric differences in flowers of the Brassicaceae. The rich variety of Cleomaceae floral forms represents a little studied but highly promising resource for understanding the evolution of key features that influence pollination. Additionally, Cleomaceae contain high concentrations of flavonoids, terpenoids, tannins, alkaloids, saponins, and anthocyanins, which could contribute to pharmaceutical discoveries and new health treatments. They also have significant potential in elucidating tolerance mechanisms to biotic and abiotic stresses, and can be consumed as food, although not traditionally cultivated. This review describes and discusses opportunities to advance research in various areas using Cleomaceae. Despite promising prospects, effective functional techniques to elucidate the diversity within this group are lacking.
