“…Moreover, a more important reaction was obtained in immature and commercial fruits than in over-mature fruits. These results agreed with those obtained by Su et al (2011) in apples, who showed that the lignin quantity measured gravimetrically was higher in wounded tissue from early harvested fruit in comparison with that from late harvest fruit.…”

“…Moreover, the differences were greater when lower inoculum concentrations were used. At 20°C, Su et al (2011) demonstrated that susceptibility of apples to Botrytis cinerea increased with fruit maturity. However, the significant differences that they obtained were between lesion diameters in the late harvest compared with optimal and early harvests but non significant differences in the percentage of decay were obtained among harvests.…”

“…Plant defence strategies against pathogen invasion may be modulated by fruit ripening (Su et al, 2011) which is itself a complex, developmentally regulated process encompassing alterations in gene expression and chemical and physiological changes (Cantu et al, 2008). However, some questions remain unanswered as to how fruit maturity may affect the infection capacity of both host and non-host pathogens.…”

“…More specifically, increased resistance to B. cinerea by mutation, chemical treatments or wounding was shown to correlate with boosting of H 2 O 2 accumulation in the host upon infection (Asselbergh et al 2007;Azami-Sardooei et al 2010;L'Haridon et al 2011;Malolepsza 2006;Su et al 2011). As in the present study, the phytohormone JA was shown by others to be needed for priming of the oxidative burst against grey mould disease (Orozco-Cardenas and Ryan 1999; Azami-Sardooei et al 2010).…”

Aims The goal of this study was to identify the induced resistance pathway mediated by biochar in the tomatoBotrytis cinerea pathosystem. Methods Tomato wild types and mutants modified in their salicylic acid (SA), ethylene (ET) or jasmonic acid (JA) metabolism were grown in a potting medium amended with biochar produced at 450ºC from greenhouse wastes, to identify the possible pathway(s) involved in biochar-mediated resistance to B. cinerea.Early cellular response of H 2 O 2 accumulation was biochemically tested, and the transcriptional changes of 12 defense-related genes upon B. cinerea challenge of detached leaflets were analyzed. Results Biochar amendment resulted in about 50 % reduction in B. cinerea disease severity in all tested genotypes with the exception of a JA deficient mutant, def1. Biochar amendment induced priming of early as well as late-acting defense responses particularly in the genes Pti5 (ET-related) and Pi2 (JA-related), which are known to be crucial in resistance against B. cinerea. Stronger and earlier H 2 O 2 accumulation subsequent to B. cinerea inoculation in all genotypes was observed as a result of biochar amendment, with the exception of the def1 mutation. Conclusion Biochar-mediated IR in the B. cinerea-tomato pathosystem involves the JA pathway.

Abstract. Tomato (Solanum Lycopersicum L.) is the second most cultivated vegetable in the world and widely used as a system for studying the role of ethylene during fruit ripening. Our objective was to study the oxidative stress and antioxidative metabolism during ripening of non transgenic tomato and transgenic line-21 tomato which reduced ethylene. The line-21 of transgenic tomato plants (RNAi ACO1) had lower ethylene production and longer shelf-life more than 32 days as compared to the wild-type fruits which have very short shelf-life. In this study, tomato fruit were divided into five different stages (MG: mature green 5%, B: breaker 25%, T: turning 50%, O: orange75%, RR: red ripe100%).The activity of lipoxygenase (LOX) and lipid peroxidation (MDA) were measured to assess changes in oxidative stress. The LOX activity and MDA content decreased significantly obtaining 2.6-fold and 1.2-fold, respectively, as compared to the wild type fruit. However, superoxide dismutase (SOD) and catalase (CAT) activities were increased to 1.9 and 1.2 folds from the mature green to the fully ripe stage in transgenic tomatoes. Furthermore, the wild type tomato increases 1.3 in SOD and 1.6 in CAT activities. The overall results indicate that the wild type tomato fruit showed a faster rate of ripening, parallel to decline in the rate of enzymatic antioxidative systems as compared to the transgenic line-21 tomato fruit. In addition, the results show that the antioxidant capacity is improved during the ripening process and is accompanied by an increase in the oxidative stress.
