“…Transcriptomic and metabolomic analysis have shown that DEGs and differential metabolites obtained in the phenylpropanoid biosynthesis pathway are significantly related under salt stress [ 41 ]. Previous studies have found that plant hormones are small chemicals that play a key role in plant growth and development [ 42 ]. Stress hormones such as salicylic acid (SA) and jasmonic acid (JA) mediate the balance between salt stress signals and control growth and stress responses.…”

As high soil salinity threatens the growth and development of plants, understanding the mechanism of plants’ salt tolerance is critical. The Chrysanthemum × grandiflora is a newly developed species with a strong salt resistance that possesses multiple genes controlling its quantitative salt resistance. Because of this multigene control, we chose to investigate the plant stress genes overall responses at the transcriptome level. C. grandiflora were treated with a 200 mM NaCl solution for 12 h to study its effect on the roots and leaves via Illumina RNA sequencing. PAL, CYP73A, and 4CL in the phenylpropanoid biosynthesis pathway were upregulated in roots and leaves. In the salicylic acid signal transduction pathway, TGA7 was upregulated in the roots and leaves, while in the jasmonic acid signal transduction pathway, TIFY9 was upregulated in the roots and leaves. In the ion transporter gene, we identified HKT1 that showed identical expression patterns in the roots and leaves. The impact of NaCl imposition for 12 h was largely due to osmotic effect of salinity on C. grandiflora, and most likely the transcript abundance changes in this study were due to the osmotic effect. In order to verify the accuracy of the Illumina sequencing data, we selected 16 DEGs for transcription polymerase chain reaction (qRT-PCR) analysis. qRT-PCR and transcriptome sequencing analysis revealed that the transcriptome sequencing results were reliable.

As high soil salinity threatens the growth and development of plants, understanding the mechanism of plants’ salt tolerance is critical. As a newly developed species with a strong salt resistance, the chrysanthemum × grandiflora possesses multiple genes that control its quantitative salt resistance. Because of this multigene control, we chose to investigate the plant’s stress genes’ overall responses at the transcriptome level. C. Grandiflora were treated with a 200 mM/L NaCl solution for 12 h, and the effect of salt stress on their roots and leaves was analyzed via Illumina RNA sequencing. Most DEGs were enriched in GO annotations of ‘biological process,’ ‘nucleus,’ and ‘protein binding’. There are many genes in plant hormone signal transduction and phenylpropane biology pathways, and we observed that most of the genes had the same expression patterns in the roots and leaves. Among them, PAL, CYP73A, and 4CL in the phenylpropane biosynthetic pathway were upregulated in roots and leaves. In the salicylic acid signal transduction pathway, TGA7 was upregulated in the roots and leaves, and in the jasmonic acid signal transduction pathway, TIFY9 was upregulated in the roots and leaves. In the ion transporter gene, we identified that HKT1 showed identical expression patterns in the roots and leaves.

“…Phytohormones are trace endogenous signaling molecules synthesized by plants, which play an important role in stress response. Under salt stress, GA content decreases and the expression of GA20ox, a key gene for GA synthesis, is downregulated (Zhu et al, 2019). Salt stress inhibits plant growth by reducing GA levels, whereas exogenous application of GA stimulates the synthesis of endogenous GA in plants, thus promoting plant growth (Niharika et al, 2020).…”

“…Plant hormones are key signaling molecules in plant responses, in particular, defense responses, to abiotic stress. One study has found that after salt stress, the gibberellin 20 oxidase (GA20ox) gene was down-regulated and the activity of GA20ox oxidase decreased synchronously, resulting in a decrease in gibberellin (GA) content and a decrease in plant growth and development (Zhu et al, 2019). Abscisic acid (ABA) can alleviate the degradation of chlorophyll under salt stress, promote the accumulation of osmotic regulatory substances, and regulate stomata to improve water balance, thereby increasing the salt adaptability of tomato and rice (Shahzad et al, 2017).…”

IntroductionSalinity critically affects the growth and development of alfalfa (Medicago sativa), making it necessary to understand the molecular mechanism of alfalfa’s adaptation to salt stress.MethodsIn this study, alfalfa roots were subjected to salt stress and transcriptomics and metabolomics analyses were performed.ResultsThe results showed that flavonoid synthesis, hormone synthesis, and transduction pathways may be involved in the alfalfa salt stress adaptation reaction, and that they are related. Combined analysis of differential genes and differential metabolites found that dihydroquercetin and beta-ring hydroxylase (LUT5), ABA responsive element binding factor 2 (ABF2), protein phosphatase PP2C (PP2C) and abscisic acid (ABA) receptor PYL2 (PYL), luteolinidin was significantly correlated with PP2C and phytochrome-interacting factor 4 (PIF4) and (+)-7-isomethyl jasmonate were significantly correlated with flavonol synthase (FLS) gene. (+)-7-isomethyl jasmonate and homoeriodictyol chalcone were significantly correlated with peroxidase (POD). POD was significantly up-regulated under NaCl stress for 6 and 24 h. Moreover, flavonoids, gibberellin (GA), jasmonic acid (JA) and ABA were suggested to play an important role in alfalfa’s response to salt stress. Further, GA,ABA, and JA may be involved in the regulation of flavonoids to improve alfalfa’s salt tolerance, and JA may be a key signal to promote the synthesis of flavonoids. DiscussionThis study revealed the possible molecular mechanism of alfalfa adaptation to salt stress, and identified a number of salt-tolerance candidate genes from the synthesis and signal transduction pathways of flavonoids and plant hormones, providing new insights into the regulatory network of alfalfa response to salt stress.
