Isolation and characterization of KD7 for the biological control of pear fire blight.

is a plant pathogen that causes fire blight disease in Rosaceous plants, such as pear and apple. To develop an effective biocontrol method to suppress , a total of 16 bacteria were isolated from pear orchard soil in China and screened for antagonistic activity . Among them, 9 isolates that exhibited antagonistic activity against were identified, including , (previously known as ) and based on the partial 16S rDNA sequence analysis and similarity search.

Genome-wide analysis of the WSD family in sunflower and functional identification of involvement in wax ester biosynthesis and osmotic stress.

The wax esters are important cuticular wax composition that cover the outer surface of plant organs and play a critical role in protection and energy metabolism. Wax ester synthesis in plant is catalyzed by a bifunctional wax ester synthase/acyl-CoA: diacylglycerol acyltransferase (WSD). Sunflower ( L.

Corrosion and Residual Strength Analysis of High Pressure Die Casting AM Series Mg Alloys.

Higher pressure die casting (HPDC) AM series (Mg-Al-Mn) Mg alloys have wide application potential in the automobile industry. To promote its application, systematic investigation on the corrosion performance and corrosion residual strength of HPDC AM50+1Ce and AM60 was carried out. The corrosion of HPDC AM50+1Ce was more uniform, while the pitting corrosion of AM60 was more severe, and the mechanical properties of HPDC AM60 was more sensitive to corrosion.
