“…GLVs are known for the aroma of crushed or injured leaves (Hatanaka, 1993;Matsui et al, 2006), and plants produce GLVs after damage and biotic or abiotic stress. GLVs are not only the main source of volatiles in fruit and vegetables -they also have important physiological functions.…”

“…GLVs are not only the main source of volatiles in fruit and vegetables -they also have important physiological functions. They are critical signals that help plants recognise and compete with other organisms (Matsui et al, 2006) and also impart resistance to pathogenic bacteria and insects (Nakamura & Hatanaka, 2002;Tufariello et al, 2012). Furthermore, GLVs are similar to the aroma from spices in the food and beverage industry (Kalua & Boss, 2009).…”

In this study we focused on the development of Cabernet Sauvignon grapes and investigated changes in the activity of alcohol dehydrogenase (ADH) and hydroperoxide lyase (HPL) in different tissues. We sampled grape skin at four, six, seven, eight, nine, 10, 12, 14 and 16 weeks after anthesis; developing flowers when blooming at 0%, 5%, 50%, and 90%; and leaves at two and four weeks before anthesis and at two, four, six, eight, nine, and 10 weeks after anthesis. We also examined the type and fluctuation of volatile contents. ADH activity increased with the development of flowers and grape skins, which led to the increasing of types and concentration of alcohols. Low levels of 9-HPL led to low concentrations of C9 compounds. According to this paper, C6 compounds became abundant with the development of grape berries, while the activity of 13-HPL kept at a low level in the flowers and grape skins. There might have been a high level of 13-HPL activity from the end of flowering until fruit setting that we did not detect. Furthermore, similar C6 and C5 compounds were detected across all tissues, including hexanal, (E)-2-hexenal, (Z)-3-hexenal, (Z)-2-penten-1-ol, (Z)-3-hexen-1-ol, 1-hexanol and 3-hexen-1-ol. Generally speaking, the concentrations of C6 and C5 compounds could be used as the criterion of maturation of the three grape tissues.

“…However, only two cucumber LOX genes, CsLOX1 and CsLOX9 (corresponding to CsLOX01 and CsLOX09 in our data, respectively), have been characterized up to now. The expression profiling of the cucumber lipoxygenase gene family and phylogenetic relationship with other plant LOX members in detail remain poorly understood (Matsui et al, 1999(Matsui et al, , 2006. In this report, we carry out the genome-wide identification, and phylogenetic and expression analysis of the lipoxygenase gene family in cucumber, as well as a comparative analysis with Arabidopsis and rice LOXs, which will be useful in conducting future functional genomic studies to understand how the molecular roles of the lipoxygenase gene family translate into a diversity of biological functions.…”

“…Specifically, the organic nutrient solution increased the gene expression of both LOX and CTR. LOX is regulated by JA (Matsui et al 2006) and CTR is controlled by ET (Xiao-Hua et al 2012). Thus, we suggest that the general elicitors in the organic nutrient solution were recognized by cucumber cells, which then activated JA and ET to regulate the over-expression of LOX and CTR, respectively.…”

“…In lettuce, Ls-ACS1 is induced by ET and auxin (Takahashi et al 2003). In addition, JA induces the lipoxygenase (LOX) gene in cucumber as a response to mechanical wounding (Matsui et al 2006). Moreover, an ET receptor-related gene (CTR) was a candidate gene for plant tolerance to abiotic stimuli in cucumber (Xiao-Hua et al 2012).…”

Organic hydroponics induces systemic resistance against the air-borne pathogen,Botrytis cinerea(gray mould)

Here, we propose that organic hydroponics trigger induced systemic resistance (ISR) in lettuce against air-borne Botrytis cinerea, which causes gray mold. We compared effects of organic and chemical hydroponics, assessed presence of ISR elicitors in the hydroponic nutrient solution, and investigated molecular mechanism of ISR. Organic hydroponics significantly reduced gray mold lesions in lettuce (cultivated hydroponically) and cucumber (cultivated in soil and foliar sprayed with nutrient solution). The 1-aminocyclopropane-1-carboxylic acid synthase gene in lettuce and lipoxygenase and ethylene receptor-related gene in cucumber showed heightened expression, suggesting that the jasmonic acid/ethylene (JA/ET)-signaling pathway was involved in ISR for both crops. Low salicylic acid β-glucoside levels confirmed role of the ISR signaling pathway. ISR in both lettuce and cucumbers indicated that elicitors in organic hydroponics were nonhost-specific and that the JA/ET pathway was activated without microbe-root interaction. Thus, organic hydroponics can be an effective method for both soil-borne and air-borne disease control.
