Screening of Sugarcane Proteins Associated with Defense against subsp. , Agent of Ratoon Stunting Disease.

Sugarcane is the most important sugar crop and one of the leading energy-producing crops in the world. Ratoon stunting disease (RSD), caused by the bacterium subsp. , poses a huge threat to ratoon crops, causing a significant yield loss in sugarcane.

Copper-Mediated and Palladium-Catalyzed Cross-Coupling of Indoles and -Methylpyridinium Salts: A Practical Way to Prepare 3-(Pyridin-2-yl)indoles.

Herein, a Pd/Cu bimetallic-catalyzed direct C-H heteroarylation of pyridines via the traceless protecting group strategy is described. A series of -methyl-activated pyridines and 1-methylindoles are coupled with high regioselectivity to produce the corresponding 3-(pyridin-2-yl)indoles in moderate to good yields, wherein related electron-rich heterocycles (e.g.
