Impacto Económico

El <em>Cucumber mosaic virus</em> (CMV) ocasiona una de las enfermedades virales más importantes a nivel mundial en plantas silvestres y cultivadas. En México son pocos los estudios que se han abordado con este virus, y dada su amplia gama de hospedantes e impacto económico, es necesario contar con mayor información de su presencia y distribución en zonas de importancia agrícola como las del estado de Colima. En este trabajo, se reportan nuevos aislamientos del CMV identificados por RT-PCR, secuenciación de DNA y su análisis filogenético: CMV-Vin en vinca (<em>Catharanthus roseus</em>), CMV-Chi en chile jalapeño (<em>Capsicum annuum</em>) y CMV-Tom en tomate saladette (<em>Solanum lycopersicum</em>). Se confirmó, además, la presencia del CMV en melón cantaloupe (<em>Cucumis melo</em>) (CMV-Mel). Los aislamientos CMV-Vin, CMV-Chi y CMV-Mel agruparon en el subgrupo IB, mientras que CMV-Tom agrupó en el subgrupo IA de CMV. De estos aislamientos, sólo CMV-Vin evidenció la presencia de un RNA satélite (satRNA Vin) sin dominio necrogénico. Este es el primer reporte de la presencia del CMV en vinca, chile y tomate y de un RNA satélite en vinca en Colima, México.

Systemic Infections

The Cucumber mosaic virus (CMV)-encoded 2b protein (Cmv2b) is a nuclear protein that suppresses transgene RNA silencing in Nicotiana benthamiana. Cmv2b is an important virulence determinant but nonessential for systemic spread in N. glutinosa, in contrast to its indispensable role for systemic infections in cucumber. Here, we report that Cmv2b became essential for systemic infections in older N. glutinosa plants or in young seedlings pre-treated with salicylic acid (SA). Expression of Cmv2b from the genome of either CMV or Tobacco mosaic virus significantly reduced the inhibitory effect of SA on virus accumulation in inoculated leaves and systemic leaves. A close correlation is demonstrated between Cmv2b expression and a reduced SA-dependent induction of the alternative oxidase gene, a component of the recently proposed SA-regulated antiviral defense. These results collectively reveal a novel activity of Cmv2b in the inhibition of SA-mediated virus resistance. We used a N. tabacum line expressing a bacterial nahG transgene that degrades SA to provide evidence for a Cmv2b-sensitive antiviral defense mechanism in tobacco in which SA acts as a positive modifier but not as an essential component. We propose that SA induces virus resistance by potentiating a RNA-silencing antiviral defense that is targeted by Cmv2b.
