“…The increased antioxidant capacity of BR treatment might be the main reason BR treatment improved the shelf life of T. sinensis buds under 4 ℃ storage and delayed the emergence of chilling injury under −2 °C storage. The results agreed with a previous study that BR treatment effectively inhibited MDA and reactive oxygen species generation and alleviated chilling injury during 4 °C storage and cold chain circulation of carambola fruit [ 19 ]. Other studies found similar results that the accumulation of MDA and hydrogen peroxide was significantly reduced by gibberellic acid treatment in T. sinensis buds during 4 ± 1 °C storage and effectively enhanced the tolerance of buds to chilling stress [ 32 ].…”

“…In the present results, the SOD activity in T. sinensis buds was increased under BR treatment by day 9 during 4 °C storage. The results were similar to those of carambola fruit treated with BR during 4 °C storage, which increased SOD activity to delay the chilling harm [ 19 ]. BR treatment increased the SOD activity, proline content, and soluble protein content by day 3 during −2 °C storage and increased the POD activity, glutathione content, and soluble protein content by day 6 during −2 °C storage.…”

“…The BR treatment delayed the chilling injury under NFPT storage of T. sinensis buds, indicating that BR treatment improved plant tolerance to cold stress during plant growth and post-harvest plant storage. Similar results showed that BR treatment alleviated the chilling injury of carambola [ 19 ] and banana [ 18 ] fruit under 4 °C and 2 °C storage, respectively.…”

“…In recent years, BRs have also attracted extensive attention in storing postharvest horticultural products. Meanwhile, BRs have been proven to reduce the chilling injury symptoms of postharvest carambola and banana [ 18 , 19 ]. BRs have also been shown to alleviate the effects of abiotic stress on plants by modifying the ascorbate-glutathione cycle and secondary metabolites [ 16 , 20 ], modulation of stress markers [ 21 ], and modulation of antioxidants [ 22 ].…”

Low temperatures are often used to preserve fruits and vegetables. However, low-temperature storage also causes problems, such as chilling injury, nitrite accumulation, and browning aggravation in plants. This study investigated the effects of brassinolide (BR,1.0 mg L−1) solution soaking, storage temperatures (−2 ± 0.5 °C, 4 ± 0.5 °C, and 20 ± 1 °C), and their combinations on nitrite content, color change, and quality of stored Toona sinensis bud. The results showed that low temperature (LT, 4 ± 0.5 °C) and near freezing-point temperature (NFPT, −2 ± 0.5 °C) storage effectively inhibited the decay of T. sinensis bud compared to room temperature (20 ± 1 °C, the control). The combined treatments of BR with LT or NFPT reduced nitrite content and maintained the color and the contents of vitamin C, carotenoids, saponins, β-sitosterol, polyphenol, anthocyanin, flavonoids, and alkaloids in T. sinensis bud. BR soaking delayed the occurrence of chilling injury during NFPT storage. Meanwhile, BR soaking enhanced the DPPH radical scavenging activity, ABTS activity, and FRAP content by increasing SOD and POD activity and the contents of proline, soluble, and glutathione, thus decreasing MDA and hydrogen peroxide content and the rate of superoxide radical production in T. sinensis bud during NFPT storage. This study provides a valuable strategy for postharvest T. sinensis bud in LT and NFPT storage. BR soaking extended the shelf life during LT storage and maintained a better appearance and nutritional quality during NFPT storage.

“…In the CI study, compared with the WT and overexpression of Sly-miR171e, silencing Sly-miR171e improved the hardness of tomato fruit, reduced its electrolyte leakage, and improved cold tolerance in the fruit. At low temperatures, plants will produce oxidative stress, that is, excessive production of ROS, including H 2 O 2 and superoxide anion (O 2− ) (28,29). H 2 O 2 is a second messenger of defense response (30)(31)(32) and is a substance that causes damage to cell membranes.…”

In this study, the role of Sly-miR171e on post-harvest cold tolerance of tomato fruit was researched. The results showed that overexpression of Sly-miR171e (miR171e-OE) promoted postharvest chilling injury (CI) of tomato fruit at the mature red (MR) and mature green (MG) stage. Contrasted with the wild type (WT) and miR171e-OE fruit, the knockdown of Sly-miR171e (miR171e-STTM) showed a lower CI index, lower hydrogen peroxide (H2O2) content, and higher fruit firmness after harvest. In the fruit of miR171e-STTM, the expression level of GRAS24, CBF1, GA2ox1, and COR, and the GA3 content were ascended, while the expression levels of GA20ox1 and GA3ox1 were descended. The research demonstrated that CI in tomato fruit was alleviated at low temperature storage by silencing Sly-miR171e with short tandem target mimic (STTM) technology. Furthermore, it also provided helpful information for genetic modification of miR171e and control of CI in the postharvest fruit.

BACKGROUNDThe effects of exogenous brassinolide (BR) treatment (3.0 μM) on phenolic biosynthesis in mung bean sprouts were investigated. This investigation included the analysis of sugar content, substrates within the phenylpropane pathway, energy substances, enzymatic activity within the phenylpropane pathway, sugar metabolism and energy metabolism.RESULTSResults showed that BR treatment significantly increased the levels of total phenolics, p‐hydroxybenzoic acid p‐coumaric acid, gallic acid, fumalic acid, and caffeic acid. This enhancement was accomplished through the elevation of L‐phenylalanine levels and the activation of enzymes associated with the phenylpropane pathway in mung bean sprouts, including phenylalanine ammonia‐lyase, cinnamate 4‐hydroxylase and 4‐coumarate CoA ligase. Furthermore, BR treatment induced alterations in sugar metabolism in mung bean sprouts as evidenced by the increased levels of glucose, fructose, sucrose and phosphoenolpyruvate. Moreover, increased activity was observed for enzymes linked to sucrose metabolism and glycolysis in the BR‐treated group. Concurrently, BR treatment bolstered the levels of adenosine triphosphate and energy charge in mung bean sprouts, which was attributed to the activation of H+‐adenosine triphosphatase, Ca2+‐adenosine triphosphatase and succinic dehydrogenase.CONCLUSIONThese results suggest that BR treatment can accelerate the accumulation of phenolic compounds in mung bean sprouts. This effect is achieved not only through the activation of the phenylpropane pathway, but also through the modulation of sugar and energy metabolism. The modulation provides ample energy and a substrate for the biosynthesis of phenolics.This article is protected by copyright. All rights reserved.
