“…Resistance induced by H is broad spectrum and long lasting, but rarely provides complete control of infection (Yang et al , 2007). The mechanism of induced resistance is involved in: accumulation of pathogenesis‐related proteins, defence enzymes and antifungal compounds; increasing of activated oxygen; lignification of epidermal cells; and occurrence of condensed tannin vacuoles in the epidermis of apple fruit (Capdeville et al , 2008; Dong et al , 1999; Yang et al , 2007). These mechanisms affect fruits decay and quality.…”

PurposeThe aim of this research is to determine the effects of pre‐harvest harpin (H) and modified atmosphere packaging (MAP) on the storage and fruit quality of cherry tomato (Lycopersicon esculentum Mill. cvs. “Alona” and “Cluster”).Design/methodology/approachH was used at 50 g 100 l‐1 concentration. First application was done on the seedlings in 3‐4 leaf stages and the other four applications were repeated at 20‐day intervals. Then, treated and untreated fruits were stored in plastic film materials with various O2 and CO2 permeabilities.FindingsWeight loss was significantly higher in tomatoes stored under normal atmosphere (NA) compared to MAP. Initial total soluble solids of 3‐4 percent increased to 7‐9 percent in without H (WH)+NA. Firmness was measured as 0.44 (“Alona”) and 1.20 kg (“Cluster”) in H+NA and 0.17 (“Alona”) and 0.30 kg (“Cluster”) in WH+NA at the end of storage. The acidity and ascorbic acid contents of tomatoes decreased during storage. Between H and WH treatments the levels of lycopene and β‐carotene were different significantly. At the end of the study, H gave successful results in both cultivars. This success was even higher especially when the H was combined with MAP. This combination slowed down the changes in TSS, firmness values. Therefore, H+50μ PE (polyethylene) treatment was effective with regard to delaying the maturity along the storage and fruit quality in cherry tomatoes.Originality/valueHe is a plant activator. It is the first bacterial hypersensitive response (HR)‐elicitor characterized. Effectiveness of H is evaluated on quality changes in treated cherry tomato fruits.

“…Segundo Capdeville et al (2008), frutos tratados com acidobenzolar-S-methyl e inoculados com P. expansum, também apresentaram resultados insatisfatórios para o controle do mofo azul, com incidência de 85% dos frutos avaliados 9 dias após a inoculação do patógeno, corroborando com os resultados obtidos neste trabalho.…”

“…Because several studies have indicated that some RIPs protect plants from fungal infection (Park et al, 2002) and transgenic plants bearing RIP genes have been constructed that are resistant to fungi (Corrado et al, 2005;Huang et al, 2008;Qian et al, 2014), we have tested the ability of BE27 to arrest the growth of the fungus P. digitatum. The Penicillium genus includes necrotrophic fungi that colonize the wounds and grow in the inter-and intracellular spaces of plant tissues (de Capdeville et al, 2008). Crucial regulatory processes and proteinprotein interactions take place in the apoplast during fungal infection (Doehlemann and Hemetsberger, 2013).…”

The ribosome-inactivating protein BE27 from sugar beet (Beta vulgaris L.) leaves is an apoplastic protein induced by signalling compounds, such as hydrogen peroxide and salicylic acid, which has been reported to be involved in defence against viruses. Here, we report that, at a concentration much lower than that present in the apoplast, BE27 displays antifungal activity against the green mould Penicillium digitatum, a necrotrophic fungus that colonizes wounds and grows in the inter- and intracellular spaces of the tissues of several edible plants. BE27 is able to enter into the cytosol and kill fungal cells, thus arresting the growth of the fungus. The mechanism of action seems to involve ribosomal RNA (rRNA) N-glycosylase activity on the sarcin-ricin loop of the major rRNA which inactivates irreversibly the fungal ribosomes, thus inhibiting protein synthesis. We compared the C-terminus of the BE27 structure with antifungal plant defensins and hypothesize that a structural motif composed of an α-helix and a β-hairpin, similar to the γ-core motif of defensins, might contribute to the specific interaction with the fungal plasma membranes, allowing the protein to enter into the cell.
