The endodermis is the central, innermost layer of cortex in land plants. It is a cylinder of compact living cells, the radial walls of which are impregnated with hydrophobic substances (Casparian strip) to restrict apoplastic flow of water to the inside. The endodermis is the boundary between the cortex and the stele.
Mesoporous silica nanoparticle-mediated delivery of DNA into arabidopsis root
InactiveUS20130185823A1MicroorganismsOther foreign material introduction processesGerm layerGene delivery
Transient gene expression is a powerful tool for plant genomics studies. Recently, the use of nanomaterials has drawn great interest. Delivery with mesoporous silica nanoparticles (MSNs) has many advantages. We used surface-functionalized MSNs to deliver and express foreign DNA in Arabidopsis thaliana root cells without the aid of particle bombardment. Gene expression was detected in the epidermis layer and in the more inner cortex and endodermis root tissues. This method is superior to the conventional gene-gun method to deliver DNA, which delivers the gene to the epidermis layer only. Less DNA is needed for the MSN method. Our system is the first use of nanoparticles to deliver DNA to plants with good efficiency and without external aids. MSNs, with multifunctionality and the capability of cargo delivery to plant cells as we demonstrated, provide a versatile system for biomolecule delivery, organelle targeting, and even agriculture, such as improved nutrient uptake.

Preparation method of uni-endodermis hollow fiber infiltrating and vaporizing membrane
The invention relates to a method for preparing a single-endoderm hollow fiber pervaporation membrane, and belongs to the membrane separation field. The pervaporation membrane has very strict requirement on the integrity and the compactness of a separating layer, and the existing dry-wet phase inversion method is difficult to directly prepare the flawless hollow fiber pervaporation membrane. Because the inside diameter of a hollow fiber membrane ranges from 0.5 to 1.5mm commonly, a coating method is hard to be directly adopted to compound the separating layer to the inner surface of fiber. Therefore, the preparation of the single-endoderm hollow fiber pervaporation membrane is a technical difficult problem. In the method for preparing the single-endoderm hollow fiber pervaporation membrane, a recycle pump is utilized to pump polycation and polyanion solution to a hollow fiber inner-cavity alternately and repeatedly; a certain negative pressure is exerted outside the fiber to form a vacuum side to realize that polyion solution is filtered under the negative pressure, thereby forming a composite layer with certain separated function on the inner surface of the hollow fiber. Pervaporation experiment shows that the preparation method can be utilized to prepare the single-endoderm hollow fiber pervaporation membrane with high performance.
