“…Our results indicated that UVB stress did not cause an increasing pattern in mushroom samples, which is similar to what was observed in shiitake mushrooms by Jiang et al (2010). It is maybe due to the fact that mushrooms do not possess a photosynthetic apparatus.…”

Abstract.Investigation of stress level might be facilitated also in plant and horticultural sciences, but currently mainly morphological parameters are in use. Antioxidant activity routinely measured in food-oriented researches and several studies indirectly indicated that stress factors can influence this parameter. Our aim was to assess the potential direct indicator role of antioxidant activity in stress conditions. We measured the effects of UVB and soil-delivered stress on Agaricus bisporus and Sedum hybridum. Our results indicate that UVB slightly decreases, while the inadequate soil conditions increase antioxidant activity; hence these measurements are suitable for determining the level of stress in different living samples.

“…Thioredoxin and cytochromes that are also involved in the reduction of oxidation stress (63) were upregulated in the fruiting body postharvest (Table S7). These antioxidant enzyme activities increased after harvest (65) in Lentinula edodes, collectively suggesting that the antioxidant defense system is induced after harvest. Protein kinases have a critical role for signal transduction in stress responses (66), and many protein kinases were upregulated after harvest (Table S7).…”

Lentinula edodes is a popular, cultivated edible and medicinal mushroom. Lentinula edodes is susceptible to postharvest problems, such as gill browning, fruiting body softening, and lentinan degradation. We constructed a de novo assembly draft genome sequence and performed gene prediction for Lentinula edodes. De novo assembly was carried out using short reads from paired-end and mate-paired libraries and by using long reads by PacBio, resulting in a contig number of 1,951 and an N 50 of 1 Mb. Furthermore, we predicted genes by Augustus using transcriptome sequencing (RNA-seq) data from the whole life cycle of Lentinula edodes, resulting in 12,959 predicted genes. This analysis revealed that Lentinula edodes lacks lignin peroxidase. To reveal genes involved in the loss of quality of Lentinula edodes postharvest fruiting bodies, transcriptome analysis was carried out using serial analysis of gene expression (SuperSAGE). This analysis revealed that many cell wall-related enzymes are upregulated after harvest, such as ␤-1,3-1,6-glucan-degrading enzymes in glycoside hydrolase (GH) families GH5, GH16, GH30, GH55, and GH128, and thaumatin-like proteins. In addition, we found that several chitin-related genes are upregulated, such as putative chitinases in GH family 18, exochitinases in GH20, and a putative chitosanase in GH family 75. The results suggest that cell wall-degrading enzymes synergistically cooperate for rapid fruiting body autolysis. Many putative transcription factor genes were upregulated postharvest, such as genes containing high-mobility-group (HMG) domains and zinc finger domains. Several cell deathrelated proteins were also upregulated postharvest.IMPORTANCE Our data collectively suggest that there is a rapid fruiting body autolysis system in Lentinula edodes. The genes for the loss of postharvest quality newly found in this research will be targets for the future breeding of strains that keep fresh longer than present strains. De novo Lentinula edodes genome assembly data will be used for the construction of a complete Lentinula edodes chromosome map for future breeding.

“…This inhibition can occur at low temperature (0-4°C) with or without the application of 1-MCP, or at higher temperatures ([4°C) when treated with 1-MCP (Jung and Watkins 2011). UV light can induce oxidative stress (Jiang et al 2010), leading to the browning of tissues. Ethylene is involved in this process and can both induce symptoms (Vranová et al 2002) or repair or protect the tissues from these stresses (Larkindale and Knight 2002).…”
