“…PPV resistance has also been obtained through specific genetic transformation. However, at present, most approaches involving transgenic processes are highly limited in the European Union (EU), as they are not socially accepted, even though their potential for reducing pesticide input has been demonstrated (Lyon, Newton & Walters 2007).…”

Sharka, a disease caused by plum pox virus (PPV), has a significant economic impact on fruit tree production. In this work, we analysed the effect of (2,1,3)-benzothiadiazole (BTH) and L-2-oxo-4-thiazolidine-carboxylic acid (OTC) on plant growth and virus content. OTC reduced sharka symptom, stimulated plant growth and alleviated PPVinduced oxidative stress, indicated by a lack of changes in some oxidative stress parameters. PPV infection reduced chloroplast electron transport efficiency. However, in the presence of BTH or OTC, no changes in the chlorophyll fluorescence parameters were observed. PPV produced an alteration in chloroplast ultrastructure, giving rise to a decrease in starch contents that was less dramatic in OTCtreated plants. Furthermore, PPV reduced the abundance of proteins associated with photosynthesis, carbohydrate and amino acid metabolism and photorespiration. These changes did not take place in OTC-treated plants, and increases in the expression of proteins related with the aforementioned processes, including ADP-glucose pyrophosphorylase, were produced, which correlated with the lower decrease in starch contents observed in PPV-infected plants treated with OTC. The results suggested that OTC treatment provides protection to the photosynthetic machinery and/or the chloroplast metabolism in PPVinfected peaches. Thus, OTC could have practical implications in agriculture in improving the vigour of different plant species as well as in immunizing plants against pathogens.Key-words: Prunus sp; antioxidative metabolism; glutathione; hydrogen peroxide; oxidative stress; plant proteomic; virus tolerance.Abbreviations: APX, ascorbate peroxidase; ASC-GSH cycle, ascorbate-glutathione cycle; BTH, (2,1,3)-benzothiadiazole; CAT, catalase; DHAR, dehydroascorbate reductase; G6PDH, glucose-6-P-dehydrogenase; GPX, glutathione peroxidase; GR, glutathione reductase; GST, glutathione-S-transferase; HPR, hydroxypyruvate reductase; MDHAR, monodehydroascorbate reductase; NPQ, non-photochemical quenching; OTC, L-2-oxothiazolidine-4-carboxylic acid; POX, peroxidase; PPV, plum pox virus; qN, coefficient of non-photochemical quenching; qP, coefficient of photochemical quenching; SOD, superoxide dismutase; TBARS, thiobarbituric acid-reactive substances; TCA, trichloroacetic acid; Y(II), effective PSII quantum yield.

“…Specifically, root responses to herbivory are controlled by the activation of a highly complex phytohormonal signaling network that includes jasmonic acid (JA), salicylic acid (SA), ethylene (ET), and abscisic acid (ABA) pathways, among others e.g., [135,136,137,138]. In the context of pest control, the manipulation of inducible resistance traits that become activated upon attack offers promising perspectives [139,140]. As for shoots, the JA pathways can also be induced in roots following root-feeder attacks although to a far lower extent [138,141].…”

Sustainable agriculture is certainly one of the most important challenges at present, considering both human population demography and evidence showing that crop productivity based on chemical control is plateauing. While the environmental and health threats of conventional agriculture are increasing, ecological research is offering promising solutions for crop protection against herbivore pests. While most research has focused on aboveground systems, several major crop pests are uniquely feeding on roots. We here aim at documenting the current and potential use of several biological control agents, including micro-organisms (viruses, bacteria, fungi, and nematodes) and invertebrates included among the macrofauna of soils (arthropods and annelids) that are used against root herbivores. In addition, we discuss the synergistic action of different bio-control agents when co-inoculated in soil and how the induction and priming of plant chemical defense could be synergized with the use of the bio-control agents described above to optimize root pest control. Finally, we highlight the gaps in the research for optimizing a more sustainable management of root pests.

“…For example prothioconazole and pyraclostobin increase grain number in spring barley in the absence of disease whereas chlorothalonil did not (Bingham et al, 2014). Biostimulants, whether specific products, the indirect effects of resistance elicitors or indirect effects of certain fungicide modes of action are even more likely to impact yield loss relationships and are another example of where molecular analyses of gene expression could be very helpful in understanding mechanisms (Lyon et al, 2014). …”

Tolerance, defined as the ability of a crop to maintain yield in the presence of disease, is a difficult characteristic to measure, and its component traits are generally undefined. It has been studied as a characteristic of plant genotypes grown singly or in monoculture crop stands. However, it is similarly valid as a characteristic of ecosystems, or mixtures / inter-cropping in crops and this paper seeks to evaluate theoretical and practical aspects of tolerance in this context. Focusing on cereals and fungal pathogens, consideration is given to the process of yield formation, the impact of disease on yield, and how tolerance might be assessed in monocultures. Variation in tolerance traits in monocultures and how such plants might interact in mixtures is considered; specifically the expression of tolerance in mixtures and how plants with contrasting tolerance traits in monocultures combine. Having focused on disease, further consideration is given to the impact of and on other microbial species in the crop environment. Finally the practical approaches that could be adopted to identify and assess the main traits responsible for expressing tolerance are addressed. These focus on the dynamic nature of plant–plant and plant-microbe interactions particularly in response to both biotic and abiotic stress out with the range of optimal or normal crop evaluation environments. It is proposed that by using more extreme factor parameter values in mixed crop evaluation environments the key traits affecting tolerance will be identified.
