The Phytoliths in the Flora of Ecuador project: Perspectives on phytolith classification, identification, and establishing regional phytolith databases [PDF]

open access: yesJournal of Archaeological Science, 2016
Abstract The Phytoliths in the Flora of Ecuador project was undertaken to establish diagnostic phytolith types and phytolith vegetation signatures to enhance archaeological and paleoenvironmental phytolith applications in the region. In this paper I discuss the “products” of this research, and provide links to on-line resources.

Comparison of Phytolith Characteristics of Three Bamboo Species’ Cotyledon Organs

open access: yesPlants
Phytoliths are widely used in plant taxonomy, paleoecology, soil silicon cycling, and agricultural archaeology. Bamboo has a strong capacity for silicon absorption, and there are some phytoliths in various organs.

Phytoliths of pteridophytes

open access: yesSouth African Journal of Botany, 2011
AbstractStudy of phytoliths of pteridophytes is an emerging area of research. Literature on this aspect is limited but increasing. Some recent findings have shown that phytoliths may have systematic and phylogenetic utility in pteridophytes. Phytoliths are functionally significant for the development and survival of pteridophytes. Experiments with some

Phenotypic and Molecular Characterisation of Silicon Uptake and Deposition in Festuca arundinacea [PDF]

open access: yes, 2017
Silicon (Si) is taken up from the soil as monosilicilic acid by plant roots, transported to leaves and deposited as phytoliths, amorphous silica (SiO2) bodies, which are a key component of anti-herbivore defense in grasses. Silicon transporters have been
