Effects of lanthanum and acid rain stress on the bio-sequestration of lanthanum in phytoliths in germinated rice seeds. [PDF]

open access: yesPLoS ONE, 2018
REEs in the environment can be absorbed by plants and sequestered by plant phytoliths. Acid rain can directly or indirectly affect plant physiological functions. Currently, the effects of REEs and acid rain on phytolith-REEs complex in plants are not yet

Silicified bulliform cells of Poaceae: morphological characteristics that distinguish subfamilies

open access: yesBotanical Studies, 2020
Background Grass phytoliths are the most common phytoliths in sediments; recognizing grass phytolith types is important when using phytoliths as a tool to reconstruct paleoenvironments.

Phytoliths in Inflorescence Bracts: Preliminary Results of an Investigation on Common Panicoideae Plants in China

open access: yesFrontiers in Plant Science, 2020
Phytoliths in the inflorescence of Poaceae plants can be of high taxonomic value in some archaeological contexts and provide insight into plant taxonomy and crop domestication processes. In this study, phytoliths in every inflorescence bract of 38 common

The microstratigraphy of middens: capturing daily routine in rubbish at Neolithic Çatalhöyük, Turkey [PDF]

open access: yes, 2011
Microstratigraphy — the sequencing of detailed biological signals on site — is an important new approach being developed in the Çatalhöyük project. Here the authors show how microscopic recording of the strata and content of widespread middens on the ...

Irrigation and phytolith formation:an experimental study [PDF]

open access: yes, 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

Phytoliths analysis for the discrimination of Foxtail millet (Setaria italica) and Common millet (Panicum miliaceum). [PDF]

open access: yesPLoS ONE, 2009
Foxtail millet (Setaria italica) and Common millet (Panicum miliaceum) are the oldest domesticated dry farming crops in Eurasia. Identifying these two millets in the archaeobotanical remains are still problematic, especially because the millet grains ...

Barnyard grasses were processed with rice around 10000 years ago [PDF]

open access: yes, 2015
Rice (Oryza sativa) is regarded as the only grass that was selected for cultivation and eventual domestication in the Yangtze basin of China. Although both macro-fossils and micro-fossils of rice have been recovered from the Early Neolithic site of ...

Evidence for mid-Holocene rice domestication in the Americas [PDF]

open access: yes, 2017
The development of agriculture is one of humankind’s most pivotal achievements. Questions about plant domestication and the origins of agriculture have engaged scholars for well over a century, with implications for understanding its legacy on global ...

Understanding Fossil Phytolith Preservation: The Role of Partial Dissolution in Paleoecology and Archaeology [PDF]

open access: yes, 2016
Opaline phytoliths are important microfossils used for paleoecological and archaeological reconstructions that are primarily based on relative ratios of specific morphotypes.
