Isolation and sexual adaptability contributed to the evolution of thousands of palm species.
Palms are vitally important due to their high vegetable oil production, which can occur in both fruits and seeds. The full range of lipid storage and composition, however, hasn’t been well understood across this large and diverse group.
This study represents the first estimate of drought-induced xylem embolism in palms across biomes and provides the first step towards understanding hydraulic adaptations in long-lived arborescent monocots.
Population structure analysis reveals the existence of two ancient gene pools that have contributed to the current diversity of Old World date palm.
