“…Besides amino acids and sugars, lipids are also important primary metabolites in plants functioning importantly in energy conversion, signal transduction, and stress response processes (Suh et al, 2015 ). Active changes to membrane lipids in plant roots have been observed under many types of abiotic stress conditions, including temperature stress (Zhao et al, 2021 ), salt stress (Xu et al, 2021 ), and nutritional stress (Nakamura, 2013 ). In legumes, lipid metabolism in the root is crucial for nodule formation and development (Zhang et al, 2020 ).…”

Peanut (Arachis hypogaea L.) is an important oil crop globally because of its high edible and economic value. However, its yield and quality are often restricted by certain soil factors, especially nitrogen (N) deficiency, and soil compaction. To explore the molecular mechanisms and metabolic basis behind the peanut response to N deficiency and soil compaction stresses, transcriptome and metabolome analyses of peanut root were carried out. The results showed that N deficiency and soil compaction stresses clearly impaired the growth and development of peanut's aboveground and underground parts, as well as its root nodulation. A total of 18645 differentially expressed genes (DEGs) and 875 known differentially accumulated metabolites (DAMs) were identified in peanut root under differing soil compaction and N conditions. The transcriptome analysis revealed that DEGs related to N deficiency were mainly enriched in “amino acid metabolism”, “starch and sucrose metabolism”, and “TCA cycle” pathways, while DEGs related to soil compaction were mainly enriched in “oxidoreductase activity”, “lipids metabolism”, and “isoflavonoid biosynthesis” pathways. The metabolome analysis also showed significant differences in the accumulation of metabolisms in these pathways under different stress conditions. Then the involvement of genes and metabolites in pathways of “amino acid metabolism”, “TCA cycle”, “lipids metabolism”, and “isoflavonoid biosynthesis” under different soil compaction and N deficiency stresses were well discussed. This integrated transcriptome and metabolome analysis study enhances our mechanistic knowledge of how peanut plants respond to N deficiency and soil compaction stresses. Moreover, it provides new leads to further investigate candidate functional genes and metabolic pathways for use in improving the adaptability of peanut to abiotic stress and accelerating its breeding process of new stress-resistant varieties.

Plants abiotic stress response and adaptation belong to the most important subjects in plants biology. Here, we present Nicotiana tabacum suspension cell lines adapted during long term cultures to high concentrations of NaCl, KCl, mannitol and sorbitol. Obtained lines differ in osmotic stress agents and final media osmolarities. RNA-seq analysis revealed similarities, as well as differences in adapted lines transcriptomes. Presented here BY-2 cells lines form a good model to reveal molecular mechanisms of plants adaptations to salt and osmotic stress on cellular level.

“…Salt–alkaline stress is an important and common abiotic stress that can cause water stress, ion toxicity, and even plant death [ 39 , 40 ]. Deepanjali Verma et al found that salt stress can activate MYC2 s through the mitogen activated protein kinase (MAPK) cascade pathway and that MYC2 s regulate the synthesis of Pro by regulating P5CS1 expression [ 41 ].…”

Abiotic stress affects metabolic processes in plants and restricts plant growth and development. In this experiment, Caucasian clover (Trifolium ambiguum M. Bieb.) was used as a material, and the CDS of TaMYC2, which is involved in regulating the response to abiotic stress, was cloned. The CDS of TaMYC2 was 726 bp in length and encoded 241 amino acids. The protein encoded by TaMYC2 was determined to be unstable, be highly hydrophilic, and contain 23 phosphorylation sites. Subcellular localization results showed that TaMYC2 was localized in the nucleus. TaMYC2 responded to salt, alkali, cold, and drought stress and could be induced by IAA, GA3, and MeJA. By analyzing the gene expression and antioxidant enzyme activity in plants before and after stress, we found that drought and cold stress could induce the expression of TaMYC2 and increase the antioxidant enzyme activity. TaMYC2 could also induce the expression of ROS scavenging-related and stress-responsive genes and increase the activity of antioxidant enzymes, thus improving the ability of plants to resist stress. The results of this experiment provide references for subsequent in-depth exploration of both the function of TaMYC2 in and the molecular mechanism underlying the resistance of Caucasian clover.
