Abstract excerpt
Silicon (Si) forms a defensive barrier in roots of Si-accumulators such as rice, blocking the absorption of toxic metals and salt, but many dicotyledons do not accumulate Si, limiting the Si application in agriculture. This may be related to differences in their cell walls: mixed-linkage glucan (MLG) exists in cell walls of monocotyledons but is absent in dicotyledons. In vivo and in vitro experiments, material...
