“…Though molecular ions were not observed, the fragmentation patterns of [M + H-glucose] + ions of the DS-GSLs were used for the analysis [17,19] (Fig. 1) [6]. This present study showed that sinigrin, glucobarbarin and gluconasturtiin were the major components which were confirmed by their molecular ion and the common fragmentation pattern of the loss of glucose (Fig.…”

“…As for NCS Ϫ , none of the reported studies could detect biological activities on the analyzed bacteria and fungi (15,32). On the other hand, a limited number of studies have demonstrated that bacteria belonging to Pseudomonas genus showed a negative chemotaxis to CH 3 SCN (33,34).…”

“…Upon tissue damage such as by insect or herbivore attack, glucosinolates are hydrolyzed by myrosinase (␤-thioglucosidase) into biologically active compounds including isothiocyanates. Isothiocyanates derived from indole glucosinolates and 4-hydroxybenzyl glucosinolates are reported to be highly unstable and yield NCS Ϫ upon reacting with various nucleophiles (15)(16)(17). Based on the enzymatic activity, the physiological role of TMT was speculated to metabolize glucosinolate breakdown products (14).…”

Almost all of the chlorine-containing gas emitted from natural sources is methyl chloride (CH 3 Cl), which contributes to the destruction of the stratospheric ozone layer. Methyl chloride (CH 3 Cl) is the most abundant halohydrocarbon emitted into the atmosphere and constitutes about 17% of the chlorine currently in the stratosphere (1). CH 3 Cl is derived mainly from natural sources and contributes to the destruction of the stratospheric ozone layer. As the total abundance of ozone-depleting gases such as chlorofluorocarbons in the atmosphere has begun to decrease in recent years as a result of The Montreal Protocol on Substances That Deplete the Ozone Layer, the impact of CH 3 Cl emission from natural sources will become greater on the atmospheric chemistry. CH 3 Cl emission into the atmosphere has been estimated at 1,700 -13,600 Gg/year (1), which underscores the great uncertainty of the estimation. Oceans (2), biomass burning (3), woodrotting fungi, and coastal salt marshes (4) are the major sources of CH 3 Cl production. Recently, it was reported that large amounts of CH 3 Cl are emitted from tropical and subtropical plants, which are hence considered as the major sources of CH 3 Cl (5-7). It was estimated that the CH 3 Cl emission from tropical plants could account for 30 -50% of the global CH 3 Cl emission (8). To accomplish an accurate estimation of CH 3 Cl production in the atmosphere through "bottom-up" approaches, elucidating the mechanisms and physiological functions of CH 3 Cl emission from plants will be important.The biological synthesis of methyl halides has been demonstrated mainly by biochemical analyses. The enzymatic activities that transfer a methyl group from S-adenosyl-L-methionine (SAM) 2 to halide ions (Cl Ϫ , Br Ϫ , I Ϫ ), which synthesize methyl halides, were first discovered in cell-free extracts of Phellinus pomaceus (a white rot fungus), Endocladia muricata (a marine red alga), and Mesembryanthemum crystallinum (ice plant, a halophytic plant) (9). Enzyme purification and cDNA cloning of the methyl chloride transferase (MCT) was first reported with Batis maritima, a halophytic plant that grows abundantly in salt marshes. As high concentrations of ions such as Cl Ϫ are often detrimental to plants, halophytic plants are considered to possess various salt tolerance mechanisms. MCT was hypothesized to control and regulate the internal concentration of Cl Ϫ , rich in the habitat in which halophytic plant grows (10, 11).In the meantime, purification of thiol methyltransferase (TMT), which methylates bisulfide (HS 2 The abbreviations used are: SAM, S-adenosyl-L-methionine; GC-ECD, gas chromatography equipped with an electron capture detector; GC-MS, gas chromatography/mass spectrometry; HOL, harmless to ozone layer; HPLC, high performance liquid chromatography; MCT, methyl chloride transferase; MS, Murashige-Skoog; RT, reverse transcription; SAH, S-adenosyl-Lhomocysteine; TMT, thiol methyltransferase.

Indolic glucosinolate pathway provides resistance to mycorrhizal fungal colonization in a non‐host Brassicaceae

et al. 2020

Most terrestrial plants form mycorrhizas, but a number of agricultural plants, including the Brassicaceae, are non-mycorrhizal. Brassicaceae can still be colonized by arbuscular mycorrhizal fungi (AMF), but species like Arabidopsis thaliana experience growth reductions following AMF colonization at similar magnitude to that of fungal pathogen infections and lack key genes necessary for nutrient exchange. Arabidopsis also produces specific secondary compounds via the modification of tryptophan, including indolic glucosinolates (IGs), which have anti-fungal properties and may therefore be involved in reducing AMF colonization. This study therefore addressed whether the ability to produce IGs facilitates resistance to AMF colonization and growth suppression. We challenged with AMF inoculation transgenic Arabidopsis lines which produce no or enhanced IGs levels in comparison with the wild-type. Arbuscular mycorrhizal fungal inoculation suppressed the development of IG-removed plants, activated their pathogen-response defenses, and enhanced AMF vesicle colonization of their root systems. Arbuscular mycorrhizal fungi had no detrimental effects on wild-type or IG-enhanced plants. Using BLAST to identify IG orthologs across 29 Brassicales, we also show that non-mycorrhizal species possess orthologous proteins for IG biosynthesis to Arabidopsis which AMF-associated Brassicales lack. In conclusion, the IG production pathway appears to serve an important and previously unknown role in reducing AMF colonization in Arabidopsis and may serve similar functions in non-host Brassicales more broadly.
