Antony van der Ent; Kathryn M. Spiers; Tanguy Jaffré; et al. Environmental and Experimental Botany 2024. doi:10.1016/j.envexpbot.2024.105877

Other claims from this paper (3)

Observation Nickel-rich laticifers were found from roots to the apical tip.
Mechanism The observed laticifer distribution suggests nickel trafficking in the network.
Method / resource Synchrotron methods permitted non-invasive reconstruction of the laticifer system.

Novel Insights Into the Hyperaccumulation Syndrome in Pycnandra (Sapotaceae)

Sandrine Isnard; Laurent L’Huillier; Adrian L. D. Paul; et al. Frontiers in Plant Science 2020. doi:10.3389/fpls.2020.559059

Other claims from this paper (6)

Intervention effect Dosing with 100 μM nickel benefited growth of P. acuminata.
Observation All plant parts were highly enriched in nickel.
Observation Latex had an extreme nickel concentration of 124 000 µg g-1.
Observation Hyperaccumulation evolved independently in two Pycnandra subgenera and five species.
Mechanism The authors propose that laticifer properties explain extreme nickel tolerance.
Recommendation The authors suggest nickel-rich laticifers may be more widespread and warrant investigation.
