Recently published high-quality reference genome assemblies indicate that, in addition to RDR1-deficiency, the loss of several key RNA silencing-associated genes may contribute to the hypersusceptibility of Nicotiana benthamiana to viruses.

The response included activating a no-cost emergency perinatal and infant feeding hotline. Both disasters coincided with a resurgence of COVID-19 infections in Louisiana.

The main steps of this process have been clarified in recent years, primarily relying on the extensive genetic resources of Arabidopsis thaliana. Our knowledge of viral diseases of crops, however, is still limited, mainly due to the fact that A.

Identifying BRCA1/2 mutation carriers enables risk assessment, surveillance, early detection and risk reduction. In certain Israeli sub-populations recurring and founder mutations have been identified and for these, testing for founder mutations is simple, efficient and cost-effective.
View Article and Find Full Text PDFRNA interference (RNAi) is an across-kingdom gene regulatory and defense mechanism. However, little is known about how organisms sense initial cues to mobilize RNAi. Here, we show that wounding to Nicotiana benthamiana cells during virus intrusion activates RNAi-related gene expression through calcium signaling.
