Ethylene Plays a Dual Role during Infection by of .

infection leads to hypertrophy of host roots and subsequent formation of galls, causing huge economic losses to agricultural producers of plants. Ethylene (ET) has been reported to play a vital role against necrotrophic pathogens in the classic immunity system. More clues suggested that the defense to pathogens in roots may be different from the acrial.

Facile design of ultrafine CoFe nanoparticles coupled with nitrogen-doped porous carbon nanosheets for non-enzymatic glucose detection.

Ultrafine CoFe nanoparticles embedded in nitrogen-doped porous carbon nanosheets (denoted as CoFe/NPCSs) are successfully synthesized by utilizing porous plant tissue as a precursor. The morphological, structural, and chemical contents of the CoFe/NPCSs and other control samples are analyzed by X-ray (powder) diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N adsorption-desorption, Raman spectroscopy, inductively coupled plasma (ICP), and X-ray photoelectron spectroscopy (XPS) techniques. The glucose oxidation and detection performances of each catalyst are evaluated by using cyclic voltammetry and chronoamperometry.
