The genetic basis of quantitative disease resistance has been studied in crops for several decades as an alternative to R gene mediated resistance. The most important disease in the potato crop is late blight, caused by the oomycete Phytophthora infestans. Quantitative disease resistance (QDR), as any other quantitative trait in plants, can be genetically mapped to understand the genetic archit...

Leaf spot and blight disease was observed on two-year-old seedlings of Dendropanax morbifera (Korean name: Hwangchil tree) during July of 2008 in Jindo Island, Korea. Symptoms included yellow-brown to dark brown irregularly enlarged spots frequently located along the veins of leaves. The lesions were often surrounded by chlorotic haloes. Severe leaf blight and subsequent defoliation occurred wh...

The Scientific Advisory Board reflects the same excitement as others associated with the RiceCAP program in preparing the path for the application of genomics to rice breeding, and especially toward two traits (milling yield and sheath blight resistance) important to the U.S. rice industry. We are impressed with the fact that the participants represent many of the best scientists in the field o...

Sheath blight is considered the second most prevalent disease in rice with no proper resistance genes identified for its resistance. Out of 14 anastomosis groups R. solani (AG1 to AG13 and AGBI), AG1 group mostly responsible infection rice. There are many effector proteins under this group, function as transcription factors. Many bioinformatics tools available determine interaction between prom...

A novel method of management maize pathogens in vitro and vivo using newly synthesized copper nanoparticles (CuNPs) has been documented this study. CuNPs have CuSO4 as a precursor, NaBH4 ascorbic acid reducing agent, polyethylene glycol 8000 (PEG-8000) stabilizing agent. Characterization Transmission Electron Microscope (TEM) confirmed the nanoparticles’ size range 35–70 nm. Fourier transform i...
