Frontiers in Environmental Science, 2022 The detection of auto-fluorescence in phytogenic, hydrated amorphous silica depositions (phytoliths) has been found to be a promising approach to verify if phytoliths were burnt or not, especially in archaeological contexts. However, it is unknown so far

Distribution of phytoliths in plants: a review
Geology, Ecology, and Landscapes, 2019 Phytoliths are ergastic siliceous substances present abundantly within intercellular spaces as well as inside the cells of numerous plants. Being made up of silica, they are nondegradable and hence found preserved as microfossils in various substrata ...

Land, 2022 Phytoremediation has become a promising technique for cleaning Pb-contaminated soils. Grasses have a phytoextractor potential for extracting metal from soil by transporting it and accumulating it in high concentrations in their shoots, and they have the ...

Irrigation and phytolith formation:an experimental study [PDF]
, 2011 It has been proposed that phytoliths from archaeological sites can be indicators of water availability and hence inform about past agricultural practices (Rosen and Weiner, 1994; Madella et al., 2009). Rosen and Weiner (1994) found that the number of

A review of carbon isotopes of phytoliths: implications for phytolith-occluded carbon sources
Journal of Soils and Sediments, 2020 Phytolith-occluded carbon (PhytOC) is mainly derived from the products of photosynthesis, which can be preserved in soils and sediments for hundreds-to-thousands of years due to the resilient nature of the amorphous phytolith silica. Therefore, stable and radioactive carbon (C) isotopes of phytoliths can be effectively utilized in paleoecological and ...

Palm Phytoliths of Mid-Elevation Andean Forests [PDF]
Frontiers in Ecology and Evolution, 2018 Palms are one of the most common tropical plant groups. They are widespread across lowland tropical forests, but many are found in higher altitudes have more constrained environmental ranges.

Two methods, two views: Integrating phytoliths in thin sections and bulk samples on the urban Dark Earths from the DIVA-site (Antwerp, Belgium). [PDF]
PLoS ONETraditionally, phytolith analyses are carried out by extraction from bulk (sediment) samples. This technique provides valuable information, not only on the morphological and/or taxonomic assignment of phytoliths, but also on their concentration ...

When biology meets materials science - Interdisciplinary applications of electron microscopy. [PDF]
J MicroscAbstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

Applied Sciences, 2022 The accumulation of metal(loid)s in phytoliths can physically immobilize the toxic materials and reduce toxicity in plant bodies and soil. Spider brake (Pteris multifida) is a well-known As hyperaccumulator that also harbors phytolith.

Phytoliths from some grasses (Poaceae) in arid lands of Xinjiang, China [PDF]
Acta Biologica Sibirica, 2021 Opal phytoliths, as silicon dioxide inclusions, are abundant in different parts of a plant. It is known that grasses are the most representative in this respect.
