“…29 The 3,7,11,15-tetramethyl-2-hexadecen-1-ol is an unsaturated long-chain fatty acid alcohol. 30 It was accumulated very high in TAG 24 leaves in stress conditions, efficiently scavenging the free radicals and imparting drought tolerance by protecting plants against oxidative stress. 31 Our results draw attention to palmitic acid, which shows a negative correlation with the drought stress response.…”

Metabolomic Profiling of Drought-Tolerant and Susceptible Peanut (Arachis hypogaea L.) Genotypes in Response to Drought Stress

Peanut is frequently constrained by extreme environmental conditions such as drought. To reveal the involvement of metabolites, TAG 24 (drought-tolerant) and JL 24 (drought-sensitive) peanut genotypes were investigated under control and 20% PEG 6000-mediated water scarcity conditions at the seedling stage. Samples were analyzed by gas chromatography–mass spectrometry (GC–MS) to identify untargeted metabolites and targeted metabolites, i.e., polyamines and polyphenols by high-performance liquid chromatography (HPLC) and ultrahigh-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS), respectively. The principal component analysis (PCA), partial least-squares discriminant analysis (PLS-DA), heat map, and cluster analysis were applied to the metabolomics data obtained by the GC–MS technique to determine the important metabolites for drought tolerance. Among 46 resulting metabolites, pentitol, phytol, xylonic acid, d-xylopyranose, stearic acid, and d-ribose were important drought-responsive metabolites. Agmatine and cadaverine were present in TAG 24 leaves and roots, respectively, during water-deficit conditions and believed to be the potential polyamines for drought tolerance. Polyphenols such as syringic acid and vanillic acid were produced more in the leaves of TAG 24, while catechin production was high in JL 24 during stress conditions. Seven metabolic pathways, namely, galactose metabolism, starch and sucrose metabolism, fructose and mannose metabolism, pentose and glucuronate interconversion, propanoate metabolism, amino sugar and nucleotide sugar metabolism, and biosynthesis of unsaturated fatty acids were significantly affected by water-deficit conditions. This study provides valuable information about the metabolic response of peanut to drought stress and metabolites identified, which encourages further study by transcriptome and proteomics to improve drought tolerance in peanut.

“…β-Cedrene is a component of Juniperus virginiana (eastern red cedar) essential oil [ 90 ] and the floral scent of Bearded Irises (Family: Iridaceae) [ 91 ]. β-Vatirenene has antioxidant activity and is produced by the plants Valeriana jatamansi (Family: Valerianaceae) [ 92 ] and Parthenium hysterophorus (Santa Maria feverfew) [ 93 ]. Aromadendrene oxide-(2) is a component of Pamburus missionis (Family: Rutaceae) essential oil [ 102 ], which induces apoptosis in skin epidermoid cancer cells [ 135 , 136 ], whereas calamene is extracted from Eryngium carlinae (toad’s herb) and displays potential antioxidant activity [ 103 ].…”

Production of Plant-Associated Volatiles by Select Model and Industrially Important Streptomyces spp.

et al. 2020

View full text Add to dashboard Cite

The Streptomyces produce a great diversity of specialized metabolites, including highly volatile compounds with potential biological activities. Volatile organic compounds (VOCs) produced by nine Streptomyces spp., some of which are of industrial importance, were collected and identified using gas chromatography–mass spectrometry (GC-MS). Biosynthetic gene clusters (BGCs) present in the genomes of the respective Streptomyces spp. were also predicted to match them with the VOCs detected. Overall, 33 specific VOCs were identified, of which the production of 16 has not been previously reported in the Streptomyces. Among chemical classes, the most abundant VOCs were terpenes, which is consistent with predicted biosynthetic capabilities. In addition, 27 of the identified VOCs were plant-associated, demonstrating that some Streptomyces spp. can also produce such molecules. It is possible that some of the VOCs detected in the current study have roles in the interaction of Streptomyces with plants and other higher organisms, which might provide opportunities for their application in agriculture or industry.

“…Parthenin has remained the focus of numerous studies evaluating the allelopathic potential of parthenium weed [ 12 , 13 , 38 ]. It is produced and sequestered in the highest concentrations in the leaf trichomes of parthenium weed, but it is not transported to the roots [ 30 , 33 ].…”

“…The phytochemistry of parthenium weed has also been investigated, with a diverse set of metabolites identified in its leaves, shoots, roots and inflorescences [1,2]. Several secondary metabolites have been associated with stress tolerance [12] or allelopathic activity [10,13]. One of the most abundant and well characterised bioactive metabolites is the sesquiterpene lactone parthenin.…”

Parthenium weed (Parthenium hysterophorus L.) is an invasive plant species in around 50 countries and a ‘Weed of National Significance’ in Australia. This study investigated the relative toxicity of the leaf, shoot and root extracts of two geographically separate and morphologically distinct biotypes of parthenium weed in Queensland, Australia. Parthenium weed exhibited higher phytotoxic, cytotoxic and photocytotoxic activity in leaf tissue extracts in contrast to shoot and root. The germination and seedling growth of a dicot species (garden cress) were inhibited more than those of a monocot species (annual ryegrass) using a phytotoxicity bioassay. The cytotoxicity of leaf extracts was assessed in a mouse fibroblast cell suspension assay and increased under high ultraviolet A(UV-A) radiation. A major secondary metabolite, parthenin, was found in abundance in leaf extracts and was positively correlated with cytotoxicity but not with photocytotoxicity or phytotoxicity. Ambrosin and chlorogenic acid were also detected and were positively correlated with germination inhibition and the inhibition of radicle elongation, respectively. In addition, other currently unidentified compounds in the leaf extracts were positively correlated with phytotoxicity, cytotoxicity and photocytotoxicity with two to three molecules strongly correlated in each case. Both parthenium weed biotypes investigated did not differ with respect to their relative toxicity, despite their reported differences in invasive potential in the field. This suggests that secondary chemistry plays a limited role in their invasion success.
