  abstract = {{B}iosilica accumulation in plant tissues is related to the transpiration stream, which in turn depends on water availability. {N}evertheless, the debate on whether genetically and environmentally controlled mechanisms of biosilica deposition are directly connected to water availability is still open. {W}e aim at clarifying the system which leads to the deposition of biosilica in {S}orghum bicolor, {P}ennisetum glaucum, and {E}leusine coracana, expanding our understanding of the physiological role of silicon in crops well-adapted to arid environments, and simultaneously advancing the research in archaeological and paleoenvironmental studies. {W}e cultivated ten traditional landraces for each crop in lysimeters, simulating irrigated and rain-fed scenarios in arid contexts. {T}he percentage of biosilica accumulated in leaves indicates that both well-watered millet species deposited more biosilica than the water-stressed ones. {B}y contrast, sorghum accumulated more biosilica with respect to the other two species, and biosilica accumulation was independent of the water regime. {T}he water treatment alone did not explain either the variability of the assemblage or the differences in the biosilica accumulation. {H}ence, we hypothesize that genetics influence the variability substantially. {T}hese results demonstrate that biosilica accumulation differs among and within {C}-4 species and that water availability is not the only driver in this process.},
