“…However, not all instances of cross-protection can be explained this way (Gerber & Sarkar, 1989;Zaitlin, 1976). Coat protein-mediated effects cannot explain cross-protection between viroid strains or protection against virus infection provided by most satellite RNAs, with the exception of turnip crinkle virus-satellite RNA interactions (Gallitelli et al, 1991;Manfre & Simon, 2008;Montasser et al, 1991;Niblett et al, 1978;Sayama et al, 1993Sayama et al, , 2001Tien & Wu, 1991).…”

In tobacco and Nicotiana benthamiana, limited cross-protection against cucumber mosaic virus strain Fny (Fny-CMV) was provided by prior inoculation with a deletion mutant lacking the 2b silencing-suppressor protein gene (Fny-CMVD2b). Cross-protection by Fny-CMVD2b did not result from induction of systemic RNA silencing. We investigated whether protection occurs through induction of localized RNA silencing by using Arabidopsis thaliana plants harbouring mutations in genes encoding the dicer-like (DCL) endoribonucleases 2, 3 and 4 involved in antiviral silencing. In wild-type A. thaliana (Col-0) plants, Fny-CMVD2b was symptomless and cross-protected against Fny-CMV infection. Cross-protection by Fny-CMVD2b against Fny-CMV infection was not abolished in dcl2, dcl3 or dcl4 mutant plants and was strongest in dcl2/4 double mutants, although in these plants and in dcl4 mutants, Fny-CMVD2b replicated to high levels and induced strong symptoms. The results suggest that Fny-CMVD2b/Fny-CMV crossprotection is not completely dependent on RNA silencing and also involves competition between these viruses.

“…In late summer 2000, more than 30 ha of Greek tomato greenhouses (Avgelis et al 2001) were affected and the disease incidence by TYLCV, in 2001, in most cases, was 80-90 %, or even 100 % (Dovas et al 2002). In the same the 1970s, Cucumber mosaic virus (CMV) severe outbreaks caused disruption and death of tomato plants in the Mediterranean region (Gallitelli et al 1991). Tomato necrosis epidemic occurred in the eastern coastal area of Spain in the late 1980s and early 1990s (García-Arenal et al 2000).…”

Nowadays, crop production is at risk due to global warming, especially in Mediterranean areas where the increase of air temperature and/or reduction of precipitation is relevant. Climate changes that are occurring can severely prejudice plant defensive mechanisms during host-pathogen interactions by modifying growth and physiology of the host plant. In particular, viral diseases cause serious economic losses destroying crops and reducing agronomic productivity, and, in some cases such as tomato crops, they become the limiting factor production of both open field and under greenhouse cultivation systems. This is because plant viruses are obligate parasites and require living tissue for their multiplication and spread. Therefore, they are able to interfere with plant metabolism and compete for host plant resources, so determining a decrease of plant growth and productivity. Severe outbreaks of Cucumber mosaic virus (CMV) and other viruses caused disruption of tomato plants in the Mediterranean region and in Southern Italy since the 1970s. In such a scenario, it is necessary to introduce new strategies for controlling plant pathogens and parasites in order to help maintain ecosystems and to boost sustainable agriculture. The aim of this work is to give an up-to-date overview on the recent breakthroughs in the use of microorganisms on plants for improving crop yields, quality and plant tolerance against pathogens. In particular, here we report a case study regarding an innovative strategy to control a viral disease (CMV) in tomato, based on the use of rhizosphere microorganism (Trichoderma harzianum, strain T-22) as an antagonist biocontrol agent (BCA).
