“…At certain time points, there was no considerable influence on the H 2 O 2 contents in cold-stressed plants ( Liu et al, 2020 ). These results support our findings as there was no major divergence in the H 2 O 2 contents at 4 o and −4 o C. In a recent report, exogenous Tre induces the rise in H 2 O 2 and nitric oxide levels in cold stressed melon plants ( Liu et al, 2021 ). In plants, CS leads to ROS production, and antioxidative enzymes display crucial responsibilities in preserving the redox stability by ROS scavenging ( Mittler, 2017 ; Hasanuzzaman et al, 2020 ).…”

“…In the recent years, limited studies have been carried out using exogenous Tre to enhance CS tolerance in different plant species, such as tomato ( Solanum lycopersicum L.) ( Liu et al, 2020 ), rice ( Oryza sativa L.) ( Fu et al, 2020 ), wheat ( Tritum aestivum L.) ( Liang et al, 2021 ), melon ( Cucumis melo L.) ( Liu et al, 2021 ), etc., and the mechanisms mediating Tre effects have not been fully discovered. Most importantly, the effect of exogenous Tre in improving the CS tolerance in rapeseed ( Brassica napus L.) is still unclear.…”

Cold stress (CS) severely affects several physiological, biochemical, and molecular mechanisms and limits the growth and production of rapeseed (Brassica napus L.). Trehalose (Tre) acts as a growth modulator, which is extensively used to improve the tolerance to multiple plant stresses. Further, Tre also serves as an external force in inducing plant signaling molecules, regulating the expression of stress-responsive genes, and enhancing the CS tolerance in plants. Nevertheless, the importance of exogenous Tre in improving the CS tolerance in rapeseed is still unclear. Therefore, the current study was designed to get mechanistic insights into Tre-mediated CS tolerance in rapeseed seedlings. To explore the Tre role, we designed four treatments [control (CK), CK + 20 mM L–1 Tre, Cold, and Cold + 20 mM L–1 Tre] and three CS conditions (4, 0, and −4°C). The results showed that Tre treatments significantly mitigated the adverse effects of CS on the seedlings and increased the survival rate of Tre-treated seedlings under CS conditions. The exogenous Tre dramatically increased the contents of osmoprotectants, including the soluble sugar (SS), soluble protein (SP), and proline (Pro), and the activities of antioxidant enzymes, such as catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), and ascorbate peroxidase (APX) were also increased under CS conditions. Additionally, Tre decreased the malondialdehyde (MDA) contents to protect the rapeseed seedlings. Moreover, Tre also remarkably augmented the expression levels of antioxidant genes (CAT12, POD34, and FSD7), CS-responsive marker genes (CBF1, CBF2, CBF4, COR6.6, COR15, COR25, COL1, and KIN1), and Tre-biosynthesis genes (TPS4, TPS8, and TPS9). Briefly, exogenous Tre not only regulates the antioxidant and osmotic balance, but it also significantly participates in Tre metabolism and signaling network to improve the CS tolerance in rapeseed. Thus, Tre-induced supervisory connections between physiological or/and biochemical attributes provide information to dissect the mechanisms of Tre-mediated CS tolerance.

“…Consistent with previous studies that trehalose could effectively alleviate the inhibitory effect of abiotic stress on plants [15][16][17], the present study showed that the application of trehalose can maintain the phenotypic properties of wheat roots, endow them with more robust vitality, and help them resist heat stress, but this characteristic is more obvious in Yangmai 18 than Yannong 19 (Figure 1). During abiotic stress (ultraviolet and heat stress, etc.…”

“…Zhao et al found that spraying trehalose can reduce the harmful effects of high temperature stress on Paeonia lactiflora pall by enhancing the antioxidant system, activating photosynthesis, and protecting cell structure [15]. Under cold stress, exogenous trehalose significantly increased the maximum quantum yield of PSII, the antioxidant enzyme activity, and endogenous H 2 O 2 and NO levels, thus stimulating the response of melon to cold stress [16]. Tomato seedlings treated with 2 mmol/L trehalose can regulate the expression of genes related to ABA synthesis and enhance the salt tolerance of tomatoes [17].…”

High temperature stress seriously limits the yield and quality of wheat. Trehalose, a non-reducing disaccharide, has been shown involved in regulating plant responses to a variety of environmental stresses. This study aimed to explore the molecular regulatory network of exogenous trehalose to improve wheat heat tolerance through RNA-sequencing technology and physiological determination. The physiological data and RNA-seq showed that trehalose reduced malondialdehyde content and relative conductivity in wheat roots, and affecting the phenylpropane biosynthesis, starch and sucrose metabolism, glutathione metabolism, and other pathways. Our results showed that exogenous trehalose alleviates the oxidative damage caused by high temperature, coordinating the effect of wheat on heat stress by re-encoding the overall gene expression, but two wheat varieties showed different responses to high temperature stress after trehalose pretreatment. This study preliminarily revealed the effect of trehalose on gene expression regulation of wheat roots under high temperature stress, which provided a reference for the study of trehalose.

“…However, in drought-stressed plants, Tre treatment caused a greater increase in SOD activity than ALA treatment. Typically, ALA and Tre has a key role in upregulating plant defense strategies against abiotic stress, for example in drought-stressed cucumber [54], and in cold stressed melon seedlings [55]. Treatment with ALA also caused increases in antioxidant enzyme activities in salt-stressed spinach [46].…”

Foliar Application of Trehalose or 5-Aminolevulinic Acid Improves Photosynthesis and Biomass Production in Drought Stressed Alpinia zerumbet

et al. 2021

Alpinia zerumbet is an important medicinal and ornamental plant species. Drought stress is a major concern for sustainable horticulture crop production under changing climate scenarios. Trehalose (Tre) and 5-aminolevulinic acid (ALA) are osmoprotectants that play important roles in mitigating plant stresses. In this study, the effects of foliar application of 25 mM Tre or 10 mg L−1 ALA on biochemical and physiological parameters of A. zerumbet seedlings and their growth were evaluated under well-watered and drought-stressed (65% of field capacity) conditions. Drought caused reductions in physiological parameters and plant growth. These decreases were accompanied by increases in leaf free proline and glycine betaine concentrations and peroxidase activities. Foliar application of Tre or ALA remediated physiological and biochemical parameters and plant growth. Overall, foliar application of ALA or Tre proved to be beneficial for mitigating drought stress in A. zerumbet.
