Article Synopsis
  • A study conducted in 2021 and 2022 collected over 7,300 samples from 36 pepper fields in southwestern France to investigate the cucumber mosaic virus (CMV) affecting Espelette pepper.
  • Five new natural host species of CMV were identified, including Arum italicum and Trifolium incarnatum.
  • A specific CMV variant was found to be very common in pepper crops (78%) and some wild plants (8%), and this variant has been previously reported in France, dating back to at least 2009.

Article Synopsis
  • RNA viruses have smart ways to use their small genomes to create many different proteins, and one of these ways is called transcriptional slippage (TS).
  • TS can cause changes in the RNA that can help the virus adapt and evolve, allowing it to make different proteins than usual.
  • Scientists have found that this slippage happens more often than expected in certain virus families and can be influenced by random factors, which means it could play a big role in how viruses change over time.

The head-to-head oriented pair of melon resistance genes, and , control resistance to races 0 and 2 and papaya ringspot virus (PRSV), respectively. They encode, via several RNA splice variants, TIR-NBS-LRR proteins, and Prv has a C-terminal extra domain with a second NBS homologous sequence. In other systems, paired R-proteins were shown to operate by "labor division," with one protein having an extra integrated domain that directly binds the pathogen's Avr factor, and the second protein executing the defense response.

In plants, introgression of genetic resistance is a proven strategy for developing new resistant lines. While host proteins involved in genome replication and cell to cell movement are widely studied, other cell mechanisms responsible for virus infection remain under investigated. Endosomal sorting complexes required for transport (ESCRT) play a key role in membrane trafficking in plants and are involved in the replication of several plant RNA viruses.

Cucumber vein yellowing virus (CVYV) is an emerging virus on cucurbits in the Mediterranean Basin, against which few resistance sources are available, particularly in melon. The melon accession PI 164323 displays complete resistance to isolate CVYV-Esp, and accession HSD 2458 presents a tolerance, i.e.
