Anaesthetic blocks trap closure and wounding response in Venus Flytraps
Diethyl ether renders flytraps unable to close their traps or respond to wounding using a mechanism with parallels in animals.
A diversity of lipid composition in the seeds and fruits of the palm family
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.
Even for specialists, floral morphology is influenced by both pollinators and climate
Climate can indirectly affect floral morphology within a species by affecting what pollinators will visit those flowers across its range.
Resistance to the herbicide 2,4-D is complex in wild radish
Resistance to 2,4-D in wild radish is complex and appears to vary in its mechanism from one population to the next, but new research suggests that lower receptivity at the plasma membrane is part of the answer.
Palms show huge variation in their resistance to drought-induced embolism
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.
