A novel nano-silicon oxides (SiOx)/chitosan complex film was prepared using ultrasonic assistant in the process of dissolving chitosan and silicon oxides (SiOx), and characterized by transmission electron microscopy. Its effect on quality preservation of tomatoes (Solanum lycopersicum L. cv. Zheza 205) was investigated under ambient temperature. The results revealed that the nano-SiOx/chitosan complex (NSCC) film retarded weight loss and softness, delayed the titratable acids and total soluble solids loss, and thus markedly extended shelf life of green tomatoes. The antimicrobial activity of tomatoes coated with NSCC film was also recorded higher compared to chitosan (Ch) films and control. In addition, the NSCC film-coated tomatoes prevent the increase of malondialdehyde content and total polyphenol content. Moreover, the peroxidase activity, phenylalanine ammonia-lyase activity, and polyphenoloxidase activity of tomatoes coated with NSCC film were found lower than that in other treatments. These data indicated that the beneficial effects of nano-SiOx/chitosan complex coating on postharvest quality were possibly associated with the lower rate of O 2 /CO 2 transmission coefficient, limiting food-borne pathogenic bacterial growth, higher antioxidant activities, and also higher reactive oxygen species (ROS) scavenging and anti-browning activities of related enzymes in the tomatoes. Further, the results of the study could be used to successfully develop a novel nano-SiOx/chitosan complex film for improving the postharvested quality of tomatoes and thus effectively utilized by the food packaging industry.

“…Accumulating evidences suggest that cellular energy is indispensable for biosynthesis of membrane lipid, while adequate supply of adenosine triphosphate (ATP) may benefit in reducing loss of membrane integrity in fruit under chilling stress (Liu et al, 2011;Marangoni, Palma, & Stanley, 1996). Maintenance of energy level by various postharvest treatments has contributed to improved chilling tolerance in harvested crops, as demonstrated in peaches (Jin, Zhu, Wang, Shan, & Zheng, 2014;Jin et al, 2013), loquats (Jin et al, 2015), mangoes (Li, Zheng, Liu, & Zhu, 2014), bananas (Li, Limwachiranon, Li, Du, & Luo, 2016;Wang, Luo, Khan, Mao, & Ying, 2015), pears (Cheng, Wei, Zhou, Tan, & Ji, 2015), cucumbers (Chen & Yang, 2013), and bamboo shoots (Liu et al, 2016). The generation and utilization of energy depend on a series of energy metabolism-related enzymes including H + -ATPase, Ca 2+ -ATPase, succinate dehydrogenase (SDH), and cytochrome C oxidase (CCO) (Jin et al, 2013).…”

“Zhongbai” papaya fruit were treated with 15 mmol/L glycine betaine ( GB ) and then refrigerated at 6°C for 40 days to study the influence of GB on chilling injury (CI) and possible mechanism associated with energy metabolism. The results exhibited that GB treatment remarkably reduced the CI severity as indicated by lower CI index during storage. GB treatment lowered electrolyte leakage and malondialdehyde content, which accounted for maintenance of membrane integrity and reduced lipid peroxidation. Moreover, GB treatment improved the energy status as revealed by increased adenosine triphosphate (ATP) level, energy charge, and activities of energy metabolism‐related enzymes including mitochondrial membrane H + ‐adenosine triphosphatase (H + ‐ ATP ase) and Ca 2+ ‐adenosine triphosphatase (Ca 2+ ‐ ATP ase), succinate dehydrogenase ( SDH ), and cytochrome C oxidase ( CCO ). The results indicate that enhanced chilling tolerance in papaya fruit by GB treatment during cold storage might be ascribed to improved energy status in association with increased activities of energy metabolism‐related enzymes.

“…A 3 mL aliquot of the supernatant was quickly neutralized to pH 6.5 with 1 M KOH, diluted to 5 mL and passed through a 0.45 mm filter. Measurements of ATP, ADP and AMP were conducted by HPLC (Waters 2695 separation module, Waters Corp, Millford, MA, USA), as previously described (Liu et al ). Energy charge was defined as the ratio of the sum of ATP and 1/2 ADP concentrations to the concentrations of ATP, ADP and AMP and calculated using the formula (Liu et al ):

E n e r g y c h \arg e = true[normalA normalT normalP + 1 / 2 normalA normalD normalP true] / [A T P + A D P + A M P] .

“…Plants have developed a complex antioxidant system (AOS) that eliminates ROS, including antioxidant enzymes, such as superoxide dismutase (SOD, EC 1.15.1.1) and catalase (CAT, EC 1.11.1.6) and non‐enzymatic antioxidants, such as ascorbic acid (AsA) (Gratão et al ; Gill and Tuteja ; Fang et al ). Other important factors that enhance plant development include adenosine triphosphate (ATP) concentration and energy charge, i.e., the ratio of the sum of ATP and 1/2 adenosine diphosphate (ADP) levels to ATP, ADP, and adenosine monophosphate (AMP) levels (Liu et al ). Therefore, it would be interesting to determine whether BRs manipulate the levels of ROS, AOS, and energy charge and, thereby, regulate spikelet differentiation and degeneration.…”

Brassinosteroids (BRs) play crucial roles in many aspects of plant development. However, their function in spikelet differentiation and degeneration in rice (Oryza sativa L.) remains unclear. Here, we investigated the roles of these phytohormones in spikelet development in field‐grown rice subjected to five different nitrogen (N) fertilization treatments during panicle differentiation. BR levels and expression of genes involved in BR biosynthesis and signal transduction were measured in spikelets. Pollen fertility and the number of differentiated spikelets were closely associated with 24‐epicastasterone (24‐epiCS) and 28‐homobrassinolide (28‐homoBL) levels in spikelets. Enhanced BR biosynthesis and signal transduction, in response to N treatment, enhanced spikelet differentiation, reduced spikelet degeneration, and increased grain yield. Increases in proton‐pumping ATPase activity, ATP concentration, energy charge, and antioxidant system (AOS) levels were consistent with 24‐epiCS and 28‐homoBL concentrations. Exogenous application of 24‐epiCS or 28‐homoBL on young panicles induced a marked increase in endogenous 24‐epiCS or 28‐homoBL levels, energy charge, AOS levels, spikelet differentiation, and panicle weight. The opposite effects were observed following treatment with a BR biosynthesis inhibitor. Our findings indicate that, in rice, BRs mediate the effects of N fertilization on spikelet development and play a role in promoting spikelet development through increasing AOS levels and energy charge during panicle development.
