“…This study's results agree with those of Luo et al (2014). Duan et al (2022) suggested that the application of SA in stressed plants could induce their tolerance by accelerating their carbohydrate metabolism. El-Tayeb et al (2006) reported that SA treatments increased the level of soluble carbohydrates, which provided some HMs tolerance in Helianthus annuus.…”

This study investigates the effects of Spirulina platensis, Chlorella vulgaris, leaves powder of Salix alba, and ethylenediaminetetraacetic acid treatments on the biochemical and yield traits of Phaseolus plants grown under wastewater irrigation. In addition, to assess the uptake and accumulation of heavy metals into the edible plant part. Water samples were obtained from each irrigation source (fresh tap water and untreated wastewater collected from El-Rahawy drain, Giza, Egypt); the plants were treated with our treatments (3 g per kg soil) at the beginning of the experiment (mixed fully into the soil). The results observed that the irrigation of Phaseolus plants with wastewater markedly stimulated the free proline contents, total phenols, superoxide dismutase, catalase, peroxidase, polyphenol oxidase, lipid peroxidation, and abscisic acid throughout the two growth stages. Indole acetic acid, gibberellic acid, yield parameters, total soluble carbohydrate, and protein in seeds were significantly reduced. The concentrations of nickel (Ni), cadmium (Cd), lead (Pb), and cobalt (Co) in Phaseolus seeds were significantly increased beyond recommended limits set by international organizations. However, our treatments significantly reduced the contents of Ni, Cd, Pb, and Co in seeds; free proline; total phenols; superoxide dismutase; catalase; peroxidase; polyphenol oxidase; lipid peroxidation; and abscisic acid in Phaseolus plants. Moreover, indole acetic acid, gibberellic acid, all yield traits, and seed components were enhanced. This study concluded that Spirulina platensis and salix leaves powder being economically and environmentally friendly can be considered an efficient strategy to mitigate the harmful effects of wastewater on plants.

“…Firstly, the up-regulation of the DEG c67297.graph_c0 (glucan endo-1,3-beta-glucosidase) may directly promote the increase in downstream glucose content [ 37 ]. In other words, the up-regulated of the above DEG would eventually increase the level of glucose, which is the main soluble sugar [ 38 ]. This increase in glucose content is in line with the increase in soluble sugar content.…”

A long juvenile period limits the breeding process of many woody plants including tree peony. To investigate the physiological and transcriptomic differences between juvenile and adult plants of tree peony and to explore the key SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) genes, which are vital in age-dependent pathways, 1-year-old and 3-year-old Paeonia delavayi plants were used to compare the relevant physiological parameters and transcriptomic profiles of the leaves in two phases of plants. The results of the physiological parameters showed that the starch content in the leaves of adult plants remained unchanged and that the soluble sugar content significantly increased compared with those in the juvenile plants. In terms of plant hormones, the contents of cytokinin-like hormone (N6-isopentenyladenine (iP)) and jasmonic acid (JA) significantly decreased, whereas the contents of auxin (indole-3-acetic acid, IAA), abscisic acid (ABA), cytokinin-like hormone (N6-isopentenyladenenosine (iPR)), and ethylene precursor (1-aminocyclopropane-1-carboxylic acid, ACC) showed no statistic difference. Transcriptome sequencing results showed that there were 194 differentially expressed genes (DEGs) between juvenile and adult plants, including 171 up-regulated DEGs and 23 down-regulated DEGs. Circadian rhythm, plant hormone signal transduction, and sugar metabolism were closely related to the juvenile-to-adult transition in P. delavayi, involving a total of 12 DEGs. In addition, a total of 13 SPL genes were identified in the transcriptome data, but only PdSPL10 (c71307.graph_c0) was differentially expressed. It was further validated via qRT-PCR analysis, indicating that PdSPL10 might be a key gene regulating the process of juvenile-to-adult in P. delavayi. Based on the above results, a hypothetical transcriptional network regulating juvenile-to-adult transition and flowering in P. delavayi was proposed. These findings provide a reference for understanding the mechanism of juvenile-to-adult transition in tree peony.

“…The SS not only acted as an important osmo-protectant against injuries to the membrane, but also played a cryoprotective role via stabilizing proteins and retaining enzyme activities [ 29 ]. Duan et al [ 30 ] reported that accumulation of SS was an important biochemical mechanism to improve freezing tolerance of Magnolia wufengensis . Gusta et al [ 27 ] also found sugar had a much greater effect on the freezing process than protein in canola.…”

Background Mangroves possess substantial ecological, social, and economic functions in tropical and subtropical coastal wetlands. Kandelia obovata is the most cold-resistance species among mangrove plants, with a widespread distribution in China that ranges from Sanya (18° 12′ N) to Wenzhou (28° 20′ N). Here, we explored the temporal variations in physiological status and transcriptome profiling of K. obovata under natural frost conditions at ~ 32oN, as well as the positive role of exogenous abscisic acid (ABA) in cold resistance. Results The soluble sugar (SS) and proline (Pro) functioned under freezing stress, of which SS was more important for K. obovata. Consistently, up-regulated DEGs responding to low temperature were significantly annotated to glycometabolism, such as starch and sucrose metabolism and amino sugar and nucleotide sugar metabolism. Notably, the top 2 pathways of KEGG enrichment were phenylpropanoid biosynthesis and flavonoid biosynthesis. For the antioxidant system, POD in conjunction with CAT removed hydrogen peroxide, and CAT appeared to be more important. The up-regulated DEGs responding to low temperature and ABA were also found to be enriched in arginine and proline metabolism, starch and sucrose metabolism, and peroxisome. Moreover, ABA triggered the expression of P5CS and P5CR, but inhibited the ProDH expression, which might contribute to Pro accumulation. Interestingly, there was no significant change in malondialdehyde (MDA) content during the cold event (P > 0.05), suggesting foliar application of ABA effectively alleviated the adverse effects of freezing stress on K. obovata by activating the antioxidant enzyme activity and increasing osmolytes accumulation, such as Pro, and the outcome was proportional to ABA concentration. Conclusions This study deepened our understanding of the physiological characters and molecular mechanisms underlying the response of K. obovata to natural frost conditions and exogenous ABA at the field level, which could provide a sound theoretical foundation for expanding mangroves plantations in higher latitudes, as well as the development coastal landscape.
