Global patterns of accumulation and partitioning of metals in halophytic saltmarsh taxa: A phylogenetic comparative approach. | LitMetric

AI Article Synopsis

  • The study examines how different saltmarsh plants globally take up and distribute metals like copper, zinc, cadmium, and lead, using a phylogenetic approach to quantify these patterns.
  • Most saltmarsh plants accumulate metals primarily in their roots, with varying degrees of translocation to shoots, particularly for copper, zinc, and cadmium, while lead remains less mobile.
  • It was found that certain plant characteristics influence these metal uptake patterns, but surprisingly, salinity tolerance doesn't correlate with how these plants absorb and transport metals.

Article Abstract

The current study represents the first attempt to analyse quantitatively, within a phylogenetic framework, uptake and partitioning patterns of copper (Cu), zinc (Zn), cadmium (Cd) and lead (Pb) in extant saltmarsh taxa globally, and to assess associations of these patterns with various plant traits indicative of their halophytic adaptations. Despite saltmarsh being diverse taxonomically, most saltmarsh taxa accumulate metals to roots at, or above, unity (> 1). Further, there is significant translocation from roots to shoot for Cu, Zn and Cd (≤ 1), however, Pb is less mobile (TF = 0.65). Patterns of accumulation were similar among families, except greater Cd accumulation to roots in members of Juncaceae. Patterns of uptake to roots and translocation to leaves were broadly similar among plant type, plant form, habitat and photosynthetic mode. Zinc is lower in the leaves of salt-secreting species for some closely related taxa, suggesting some species co-excrete sodium (Na) and Zn through glands in leaf tissue. Salinity tolerance has no relationship to metal uptake and translocation. Translocation of Zn is greater at lower Zn sediment exposures, reflecting its active uptake and essentiality, but such bias does not affect outcomes of analyses when included as a covariate.
