The effect of Silicon on the organically grown iceberg lettuce growth and quality

Agraarteadus, 2017
Si helps plants to mitigate with abiotic and biotic stresses because of Si-treated plants become stronger, sturdier and naturally more tolerant. The purpose of the investigations was to look the effect of Silicon on the iceberg lettuce growth and quality.

Direct evidence of the molecular basis for biological silicon transport

Nature Communications, 2016
Diatoms sheath themselves in a self-made casing of silica, which requires the function of silicic acid transporters. Here, the authors identify versions of these transporters that are experimentally tractable, and develop a fluorescence method to study ...
