La uchuva es una de las frutas promisorias para la zona andina Colombia gracias a su alta demanda internacional. En Antioquia, siembra se concentra en el oriente, aunque otras subregiones como norte y suroeste presentan condiciones óptimas cultivo. Ya que enfermedades origen viral son uno los problemas emergentes este frutal, estudio evaluó infección virus RNA infectan cultivos Antioquia. Para ...

Hypersensitive response (HR)-conferred resistance to viral infection restricts the virus spread and is accompanied by the induction of cell death, manifested as the formation of necrotic lesions. While it is known that salicylic acid is the key component in the orchestration of the events restricting viral spread in HR, the exact function of the cell death in resistance is still unknown. We sho...

BACKGROUND Mating behaviors in simple invertebrate model organisms represent tractable paradigms for understanding the neural bases of sex-specific behaviors, decision-making and sensorimotor integration. However, there are few examples where such neural circuits have been defined at high resolution or interrogated. METHODOLOGY/PRINCIPAL FINDINGS Here we exploit the simplicity of the nematode...

By combining high-throughput sequencing (HTS) with experimental evolution, we can observe the within-host dynamics of pathogen variants of biomedical or ecological interest. We studied the evolutionary dynamics of five variants of Potato virus Y (PVY) in 15 doubled-haploid lines of pepper. All plants were inoculated with the same mixture of virus variants and variant frequencies were determined...

Abstract Testing for potato viruses is globally very important to prevent a critical shortage of supply. In most countries, testing obligated by law. Germany, seed potatoes are monitored six viruses: PLRV, PVY, PVM, PVA, PVX and PVS. They can cause up 90% loss tubers in the field. Common methods currently used ELISA conventional real-time PCR, but both time-consuming, former needs high capacity...
