“…Among them, five SAUR s were inhibited by the salt treatment at all time points, and this result is different from that of previous studies [ 37 , 38 , 39 ]. It has been elucidated that IAA regulates plant morphogenesis under stress conditions, including vegetative and reproductive growth [ 2 , 40 , 41 , 42 ]. IAA, Transport Inhibitor Response 1 (TIR1) and the auxin signal transduction-related protein (AFB) combine to form a complex, which leads to the ubiquitination and degradation of AUX/IAA, restrains the function of auxin response factors (ARFs) and negatively affects the expressions of the downstream transcription factors small auxin-upregulated RNAs (SAURs) [ 43 ].…”

Salt stress is one of the main abiotic stresses that strongly affects plant growth. Clarifying the molecular regulatory mechanism in ornamental plants under salt stress is of great significance for the ecological development of saline soil areas. Aquilegia vulgaris is a perennial with a high ornamental and commercial value. To narrow down the key responsive pathways and regulatory genes, we analyzed the transcriptome of A. vulgaris under a 200 mM NaCl treatment. A total of 5600 differentially expressed genes were identified. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis pointed out that starch and sucrose metabolism and plant hormone signal transduction were significantly improved. The above pathways played crucial roles when A. vulgaris was coping with salt stress, and their protein–protein interactions (PPIs) were predicted. This research provides new insights into the molecular regulatory mechanism, which could be the theoretical basis for screening candidate genes in Aquilegia.

“…In recent years, RNA-seq analysis based DEGs and candidate gene identification has been used to study salt tolerance in numerous plants, including Arabidopsis ( Sako et al, 2021 ), rice ( Chandran et al, 2019 ), bread wheat ( Amirbakhtiar et al, 2021 ), Chinese cabbage ( Li et al, 2021 ), drought/salt-tolerant Caragana korshinskii ( Li et al, 2016 ), a model halophytic Chenopodium quinoa ( Ruiz et al, 2019 ), Cenostigma pyramidale ( Frosi et al, 2021 ), and Ricinus communis ( Lei et al, 2021 ). These studies have identified abundant DEGs, candidate upregulated genes, and the functional enrichment of GO terms and pathways related to salt stress responses in plants.…”

Salt stress results in the severe decline of yield and quality in wheat. In the present study, salt-tolerant Tritipyrum (“Y1805”) and salt-sensitive wheat “Chinese Spring” (“CS”) were selected from 121 wheat germplasms to test their physiological, antioxidant enzyme, and transcriptomic responses and mechanisms against salt stress and recovery. 56 chromosomes were identified in “Y1805” that comprised A, B, and D chromosomes from wheat parent and E chromosomes from Thinopyrum elongatum, adding to salt-tolerant trait. Salt stress had a greater inhibitory effect on roots than on shoots, and “Y1805” demonstrated stronger salt tolerance than “CS.” Compared with “CS,” the activities of superoxide dismutase and catalase in “Y1805” significantly increased under salt stress. “Y1805” could synthesize more proline and soluble sugars than “CS.” Both the net photosynthetic rate and chlorophyll a/b were affected by salt stress, though the level of damage in “Y1805” was significantly less than in “CS.” Transcriptome analysis showed that the differences in the transcriptional regulatory networks of “Y1805” were not only in response to salt stress but also in recovery. The functions of many salt-responsive differentially expressed genes were correlated closely with the pathways “peroxisome,” “arginine and proline metabolism,” “starch and sucrose metabolism,” “chlorophyll and porphyrin metabolism,” and “photosynthesis.”

“…4 ). Lei et al. (2021) conducted transcriptome sequencing of salt-treated Ricinus communis L. and found that PP2C genes were up-regulated in salt-treated cultivated R. communis , which inhibited the activity of SnRK2 kinase and further promoted the up-regulation of downstream ABF genes.…”

Salinity is one of the major abiotic stress that limits crop growth and productivity. We investigated the transcriptomes of salt-treated soybean seedlings versus a control using RNA-seq to better understand the molecular mechanisms of the soybean (Glycine max L.) response to salt stress. Transcriptome analysis revealed 1,235 differentially expressed genes (DEGs) under salt stress. Several important pathways and key candidate genes were identified by KEGG enrichment. A total of 116 differentially expressed transcription factors (TFs) were identified, and 17 TFs were found to belong to MYB families. Phylogenetic analysis revealed that these TFs may be involved in salt stress adaptation. Further analysis revealed that GmMYB46 was up-regulated by salt and mannitol and was localized in the nucleus. The salt tolerance of transgenic Arabidopsis overexpressing GmMYB46 was significantly enhanced compared to wild-type (WT). GmMYB46 activates the expression of salt stress response genes (P5CS1, SOD, POD, NCED3) in Arabidopsis under salt stress, indicating that the GmMYB46 protein mediates the salt stress response through complex regulatory mechanisms. This study provides information with which to better understand the molecular mechanism of salt tolerance in soybeans and to genetically improve the crop.
