 note = {Little is known about silicon as an essential nutrient in plants, despite the deficiency symptoms associated with rice reproductive structures under silicon deprivation conditions. Silicon concentrations in the embryos of rice, peanut and other plants were compared, and the presence of silicon in the polynucleic acids (PNA) extracted from embryos of rice (Oryza sativa L.), a siliceous plant, and peanut (Arachis hypogaea L.), a calciphilous plant, was demonstrated using molecular sieve chromatography. Silicon co-eluted with RNA and DNA from both rice and peanuts, and the ratio of silicon to RNA or DNA in each fraction differed between plant embryos, and between nucleic acids. The ratio of silicon to DNA was higher than to RNA in both rice and peanut, and was higher in the peanut embryo than in the rice embryo, while silicon to RNA was opposite to the result of DNA. Digestion with DNase or RNase significantly reduced the peak of silicon associated DNA or RNA. Although aluminum was not found in the embryos of plant species except thea and maize, silicon was found in the embryos of all tested plant species. These results indicate that silicon combines with DNA and RNA in the PNA of plant embryos, suggesting that silicon is essential for plant reproduction.},
