Ecotoxicity test results for the paper entitled "Evaluation of a bioelectrochemical reductive/oxidative sequential process for chlorinated aliphatic hydrocarbons (CAHs) removal from a real contaminated groundwater"
<p>Within the frame of the ELECTRA No. 826244 H2020 project, a sequential reductive/oxidative bioelectrochemical process at a laboratory scale was tested with real groundwater from a contaminated site in Northern Italy for chlorinated aliphatic hydrocarbons (CAHs) removal. The changes in groundwater ecotoxicity were followed by a complex ecotoxicity test battery including testorganisms from various trophic levels. The datasets (supplementary to Chapter 3.5) for this publication are presented here.

Recent replenishment of aliphatic organics on Ceres from a large subsurface reservoir
<p>Ceres hosts significant aliphatic-organic concentrations, ranging from approximately 5 wt.% to >30 wt.% in specific surface areas. The origins and persistence of these organics are under debate due to the intense aliphatic signature and radiation levels in Ceres' orbit, which would typically lead to their destruction, hindering detection. To investigate this, we conducted laboratory experiments to replicate how the signature of the organic-rich regions would degrade due to radiation. Our findings indicate a fast degradation rate, implying the exposure of buried organics within the last few million years. This degradation rate, coupled with observed quantities, implies that the aliphatics must be present in substantial quantities within the shallow subsurface. Our estimates suggest an initial aliphatic abundance 2-30 times greater than currently observed, surpassing significantly the levels found in carbonaceous chondrites, indicating either a significant concentration or remarkable purity.</p>

Arabidopsis Glutathione-S-Transferases GSTF11 and GSTU20 function in Aliphatic Glucosinolate Biosynthesis
<p>GSH conjugation with intermediates is required for the biosynthesis of glucosinolate (GSL) by serving as a sulfur supply. Glutathione-S-transferases (GSTs) primarily work on GSH conjugation, suggesting their involvement in GSL metabolism. Although several GSTs, including GSTF11 and GSTU20, have been recently postulated to act in GSL biosynthesis, molecular evidence is lacking. Here, we demonstrated that <i>GSTF11</i> and <i>GSTU20</i> play nonredundant, although partially overlapping, roles in aliphatic GSL biosynthesis. In addition, <i>GSTU20</i> plays a more important role than<i> GSTF11</i>, which is manifested by the greater loss of aliphatic GSLs associated with <i>GSTU20</i> mutant and a greater number of differentially expressed genes in <i>GSTU20</i> mutant compared to <i>GSTF11</i> mutant. Moreover, a double mutation leads to a greater aggregate loss of aliphatic GSLs, suggesting that <i>GSTU20</i> and <i>GSTF11</i> may function in GSL biosynthesis in a dosage-dependent manner. Together, our results provide direct evidence that <i>GSTU20</i> and <i>GSTF11</i> are critically involved in aliphatic GSL biosynthesis, filling the knowledge gap that has been speculated in recent decades.</p>

Data from: Asymmetric adaptation to indolic- and aliphatic-glucosinolates in the B and Q sibling species of Bemisia tabaci (Hemiptera: Aleyrodidae)
The role glucosinolates play in defending plants against delicate phloem feeders such as aphids and whiteflies is currently not clear as these herbivores may avoid bringing glucosinolates from the phloem sap into contact with myrosinase enzymes. Here, we investigated the effects of high levels of aliphatic- and indolic-glucosinolates on life history traits and detoxification gene expression in two sibling species, B and Q, of the whitefly Bemisia tabaci. High levels of aliphatic-glucosinolates decreased the average oviposition rate of both species, and reduced the survival and developmental rate of Q nymphs. High levels of indolic-glucosinolates decreased the oviposition rate and survival of nymphal stages of the B species and the developmental rate of both species. Molecular analyses revealed two major asymmetries between the B and Q species. First, specific GST genes (BtGST1 and BtGST2) were significantly induced during exposure to indolic-glucosinolates only in Q. This may reflect the genes putative involvement in indolic-glucosinolates detoxification and explain the species' good performance on plants accumulating indolic-glucosinolates. Second, the constitutive expression of eight of the ten detoxification genes analyzed was higher in the Q species than in the B species. Interestingly, four of these genes were induced in B in response to high levels of glucosinolates. It seems, therefore, that the B and Q species differ in their "optimal defense strategy". B utilizes inducible defenses which are profitable if the probability of experiencing the stress is small and its severity is low, while Q invests significant resources in being always "ready" for a challenge.
