“…Meanwhile, ISR is not associated with the activation of PR genes. The pathogenesis-related genes (PR-1a, PR-5) as SAresponsive genes are induced in the systemic acquired resistance (Zhang et al 2010). In our study, the expressions of PR1a and PR-5 were not different between the treated fruits and the control fruits, which suggests that induced resistance by trans-2-hexenal may be independent of the SA-mediated pathway.…”

Trans-2-hexenal is a biocidal molecule released in many fruits and vegetables. In this paper, the effects of trans-2-hexenal on the control of postharvest diseases in tomato fruits were investigated. We indicated that the incidence of natural infection and infection by Botrytis cinerea in tomato fruits was significantly decreased after treatment with trans-2-hexenal. Trans-2-hexenal increased the mRNA levels of genes encoding ethylene receptors, lipoxygenase and phenylalanine ammonia lyase (PAL), but did not induce the mRNA accumulation of the pathogenesis-related proteins, such as PR-1a or PR-5. The activities of peroxidases and PAL and the accumulation of phenolic compounds were significantly enhanced after trans-2-hexenal treatment. This is the first report of trans-2-hexenal as an elicitor and its ability to control the postharvest diseases in tomato fruits. These results suggest that the controlling effects of trans-2-hexenal on both natural infection and gray mould in tomato fruits might be related to JA/ETmediated induced systemic resistance.

Withania somnifera (L.) Dunal is a valued medicinal plant with pharmaceutical applications. The present study was undertaken to analyze the salicylic acid induced leaf transcriptome of W. somnifera. A total of 45.6 million reads were generated and the de novo assembly yielded 73,523 transcript contig with average transcript contig length of 1620 bp. A total of 71,062 transcripts were annotated and 53,424 of them were assigned GO terms. Mapping of transcript contigs to biological pathways revealed presence of 182 pathways. Seventeen genes representing 12 pathogenesis-related (PR) families were mined from the transcriptome data and their pattern of expression post 17 and 36 hours of salicylic acid treatment was documented. The analysis revealed significant up-regulation of all families of PR genes by 36 hours post treatment except WsPR10. The relative fold expression of transcripts ranged from 1 fold to 6,532 fold. The two families of peroxidases including the lignin-forming anionic peroxidase (WsL-PRX) and suberization-associated anionic peroxidase (WsS-PRX) recorded maximum expression of 377 fold and 6532 fold respectively, while the expression of WsPR10 was down-regulated by 14 fold. Additionally, the most stable reference gene for normalization of qRT-PCR data was also identified. The effect of SA on the accumulation of major secondary metabolites of W. somnifera including withanoside V, withaferin A and withanolide A was also analyzed and an increase in content of all the three metabolites were detected. This is the first report on expression patterns of PR genes during salicylic acid signaling in W. somnifera.

“…In Malus hupehensis, these PR genes were responsive to not only SA but also MeJA (J. Zhang et al, 2010). Here, we found candidate sequences for each PR1 (one), PR3 (four), and PR5 (one ; Table S2).…”

Plants sense and respond to microbes utilizing a multilayered signalling cascade. In seed plants, the phytohormones jasmonic and salicylic acid (JA and SA) are key denominators of how plants respond to certain microbes. Their interplay is especially well-known for tipping the scales in plants' strategies of dealing with phytopathogens. In non-angiosperm lineages, the interplay is less well understood, but current data indicate that it is intertwined to a lesser extent and the canonical JA/SA antagonism appears to be absent. Here, we used the water fern Azolla filiculoides to gain insights into the fern's JA/SA signalling and the molecular communication with its unique nitrogen fixing cyanobiont Nostoc azollae, which the fern inherits both during sexual and vegetative reproduction. By mining large-scale sequencing data, we demonstrate that Azolla has most of the genetic repertoire to produce and sense JA and SA. Using qRT-PCR on the identified biosynthesis and signalling marker genes, we show that Azolla is responsive to exogenously applied SA. Furthermore, exogenous SA application influenced the abundance and gene expression of Azolla's cyanobiont. Our data provide a framework for JA/SA signalling in ferns and suggest that SA might be involved in Azolla's communication with its vertically inherited cyanobiont.
