“…When M. flos-aquae and M. aeruginosa were kept in different N forms such as NaNO 3 , NaNO 2 , NH 4 Cl, urea, serine, lysine, and arginine, they released different amount and components of VOCs, and the emission amount increased with reducing N concentration, with the maximum emission under non-N condition (Xu et al, 2017; Zuo et al, 2018a). Similarly increased emission of alcohols and β-cyclocitral was also detected when M. aeruginosa cells exhausted nitrate N nutrient after 35 days (Hasegawa et al, 2012).…”

“…Similarly increased emission of alcohols and β-cyclocitral was also detected when M. aeruginosa cells exhausted nitrate N nutrient after 35 days (Hasegawa et al, 2012). Under non-N condition, M. aeruginosa cells significantly up-regulated the expression of 4 genes which encoded pyruvate kinase, malic enzyme, phosphotransacetylase and aspartate aminotransferase, respectively (Zuo et al, 2018a). Pyruvate and acetyl-CoA are immediate precursors of isoprene and monoterpenes in MEP and sesquiterpenes in mevalonate pathway (MVA) (Figure 2), respectively.…”

“…Aspartate aminotransferase functioned in the synthesis of phenylalanine in the last step of shikimate pathway (Maeda et al, 2011). Non-N condition induced the expression of genes that were involved in the formation of terpenoid and benzenoid precursors and promoted VOC emission (Zuo et al, 2018a).…”

A wide spectrum of volatile organic compounds (VOCs) are released from algae in aquatic ecosystems. Environmental factors such as light, temperature, nutrition conditions and abiotic stresses affect their emission. These VOCs can enhance the resistance to abiotic stresses, transfer information between algae, play allelopathic roles, and protect against predators. For homogeneous algae, the VOCs released from algal cells under stress conditions transfer stress information to other cells, and induce the acceptors to make a preparation for the upcoming stresses. For heterogeneous algae and aquatic macrophytes, the VOCs show allelopathic effects on the heterogeneous neighbors, which benefit to the emitter growth and competing for nutrients. In cyanobacterial VOCs, some compounds such as limonene, eucalyptol, β-cyclocitral, α-ionone, β-ionone and geranylacetone have been detected as the allelopathic agents. In addition, VOCs can protect the emitters from predation by predators. It can be speculated that the emission of VOCs is critical for algae coping with the complicated and changeable aquatic ecosystems.

“…Thus, concentrations above 15% of the exhausted compost started to compromise the development of melon in the initial phase, this availability may have been enhanced with the action of microorganisms present in the composition of the organic compost, thus increasing the cycling of nutrients and that became available in high concentrations in the substrate [16,17].…”

Introduction: One of the attributes responsible for the good quality of the seedlings is their cultivation on substrates with good drainage and availability of nutrients, where the use of alternative sources of organic matter makes it a strategy for seedling producers. Objective: The objective of this work was to evaluate the initial development of melon when grown in different concentrations of exhausted peat organic compost. Materials and Methods: The experiment was carried out in September 2019, at Faculdades Integradas Stella Maris (FISMA), located in the Municipality of Andradina, State of São Paulo, at geographic coordinates 20°53'26,482"S and 51°22'24,822"W and with altitude approximately 396 meters above sea level. A completely randomized design was used, in a 2x5 factorial scheme, with two varieties of melon (V), namely: Goldmine and Imperial interacting with five concentrations of exhausted peat organic compound (C), that is: zero%; 3%; 6%; 13% and 25% and with four repetitions, totaling 40 plots or plastic vases. Conclusion: It is recommended to use 15% exhausted peat compound in the composition of the substrate in the initial phase of the melon. The melon varieties showed similar responses in terms of exhausted peat compound concentrations.

“…Gene abundances were quantified by RSEM software and the quantification of gene expression level was normalized using FPKM (Fragments Per Kilobase of transcript per Million mapped reads) method [30]. Differentially expressed genes (DEGs) in all samples were identified using DESeq R package [31]. The log2 (fold change) over 1 and false discovery rate (FDR) within 0.05 were set as the threshold for significant DEGs [25].…”

Oxidative Stress Response of Aspergillus oryzae Induced by Hydrogen Peroxide and Menadione Sodium Bisulfite

Oxidative stress response protects organisms from deleterious effects of reactive oxygen species (ROS), which can damage cellular components and cause disturbance of the cellular homeostasis. Although the defensive biochemical mechanisms have been extensively studied in yeast and other filamentous fungi, little information is available about Aspergillus oryzae. We investigated the effect of two oxidant agents (menadione sodium bisulfite, MSB, and hydrogen peroxide, H2O2) on cellular growth and antioxidant enzyme induction in A. oryzae. Results indicated severe inhibition of biomass and conidia production when high concentration of oxidants was used. Transcriptomic analysis showed an up-regulated expression of genes involved in oxidoreduction, such as catalase, glutathione peroxidase, and superoxide dismutase. In addition, it was observed that oxidative stress stimuli enhanced the expression of Yap1 and Skn7 transcription factors. Further, metabolomic analysis showed that glutathione content was increased in the oxidative treatments when compared with the control. Moreover, the content of unsaturated fatty acid decreased with oxidative treatment accompanying with the down-regulated expression of genes involved in linoleic acid biosynthesis. This study provided a global transcriptome characterization of oxidative stress response in A. oryzae, and can offer multiple target genes for oxidative tolerance improvement via genetic engineering.
