Abstract: Provided are a method for preparing a gel composite material with a piezoelectric property, and the gel composite material and use thereof, which belongs to the field of intelligent road traffic. In the method, titanium-containing blast furnace slag and metal oxides (PbO and ZrO2) are sufficiently and uniformly mixed, an obtained mixture is calcined under a certain thermal system, on the theoretical basis of mineral-phase reconstruction-synergistic regulation of all valuable components, and the mixture is cooled to a room temperature with a furnace to obtain the gel composite material with a piezoelectric property.

Abstract: This invention relates to methods for the transformation of Setaria species such as Setaria viridis and transformed plants produced according to the method. Specifically, this invention relates to direct transformation of callus derived from mature embryos using Agrobacterium-mediated transformation, and plants regenerated from the transformed callus tissue. The methods comprise utilizing Setaria mature embryos as the source of plant material for callus induction; induced calli can be infected by Agrobacterium hosting an appropriate vector. Transgenic plants are regenerated from transgenic calli grown under conditions favoring growth of transformed cells while substantially inhibiting growth of non-transformed cells. These methods provide for significantly increased plant transformation efficiency with minimal ratio of escapes.

Abstract: This invention relates to methods for the transformation of Brachypodium sp. and transformed plants produced according to the method. Specifically, this invention relates to direct transformation of callus derived from immature embryos using Agrobacterium-mediated transformation, and plants regenerated from the transformed callus tissue. The methods comprise utilizing Brachypodium sp. immature embryos as the source of plant material for callus induction; induced calli can be infected by Agrobacterium hosting an appropriate binary vector. Transgenic plants are regenerated from transgenic calli grown under conditions favoring growth of transformed cells while substantially inhibiting growth of non-transformed cells. These methods provide for significantly increased plant transformation efficiency with minimal ratio of escapes.
