Summary: The study demonstrated that glycinebetaine (GB) can enhance chilling tolerance in tomato plants by protecting chloroplast ultrastructure, mitigating PSII photoinhibition, and maintaining PSII stability under chilling stress. GB also increased electron transfer rate and cyclic electron flow, reduced reactive oxygen species production, and alleviated PSI photodamage. Introduction of the GB biosynthetic pathway and exogenous GB application are effective strategies for improving chilling tolerance in tomato plants.

Summary: Heavy metals like Cd pose environmental problems and threats to various organisms. This study investigated the effects of Cd on the growth and activities of PSI and PSII in Chlorella pyrenoidosa. The results showed that Cd had a more severe inhibition on PSII than on PSI. Cd decreased the efficiency of PSII's energy utilization under high light. However, the quantum yield of PSI did not show significant differences among different Cd treatments. Activation of CEF played a crucial role in the induction of NPQ. The binding features of Cd ions and photosystem particles suggested that Cd had a stronger affinity for PSII than for PSI.

Summary: In this study, the activity of ferredoxin (Fd)-dependent cyclic electron flow (Fd-CEF) around photosystem I (PSI) in intact leaves of Arabidopsis thaliana was investigated. The oxidation rate of Fd reduced by PSI (vFd) and photosynthetic linear electron flow activity were measured simultaneously under actinic light illumination. The results showed that vFd exhibited a curved response to the photosynthetic linear electron flow activity, with a linear relationship at lower flow activity and a sharp increase at higher flow activity, indicating the presence of excess vFd resulting from electron flow over photosynthetic linear electron flow. Furthermore, the excess vFd was also observed in NAD(P)H dehydrogenase-deficient mutants.

Summary: Cold storage is the best method for prolonging fruit storage, but tropical fruit are susceptible to cold storage. The application of phenylalanine after harvest can enhance the chilling tolerance of mango fruit by regulating metabolic and defense-related pathways, maintaining high levels of flavonoids and antioxidants, and reducing oxidative damage.

Summary: Photosynthesis, powered by sunlight, is crucial for the survival of most life forms. The light-driven electron transfer at photosystem I generates important reducing power at the cellular level, determining the total global enthalpy in living systems. Studying the structure of photosynthetic machinery is essential for understanding its mode of action.

Summary: This study investigated the effects of arginine on the postharvest quality of sweet cherry fruits. The results showed that arginine reduced electrolyte leakage, active oxygen production, and lipid peroxidation in the fruits. It also increased the activity of antioxidant enzymes and improved the firmness of the fruits. Furthermore, arginine decreased chilling injury and weight loss, while increasing titratable acid, soluble solids, and vitamin C content in the fruits.

Summary: This study revealed that the decline in CO2 assimilation at frequencies of 10 Hz and lower was associated with the formation of nonphotochemical quenching (NPQ) and a restriction of electron flows toward PSI. The results suggest that under these conditions, there is a favoring of accumulation of harmless P-700(+) at the expense of decreased quantum yield of photochemistry for PSII.

Summary: The present study investigated the effect of thiamin on chilling injury in Elberta peach fruit during storage. Thiamin at concentrations of 0, 100, and 200 mg l-1 effectively reduced the occurrence of chilling injury, with the best effect observed at 200 mg l-1. Thiamin treatment also reduced lipid peroxidation and peroxide hydrogen content, and induced antioxidant enzyme activity in peach fruit, ultimately enhancing fruit quality.

Summary: A slow-down switch in photosystem II (PSII) has been found to limit H-2 generation from Chlamydomonas reinhardtii under anoxia, reducing photosynthetic productivity by three-fold. This activation occurs within 10 seconds of illumination and can be reversed after 15 minutes of dark anoxia. Understanding the mechanism of this switch provides insights into anoxic photosynthesis and offers potential strategies to improve bio-energy production.

Summary: Identity recognition in plants, particularly in the context of invasive species, can play a significant role in reducing intraspecific competition and enhancing overall population fitness. In this study, invasive Eupatorium adenophorum exhibited higher identity recognition ability in high density conditions compared to two native congeners, which contributed to its high population fitness. Recognition can alleviate competition through reducing carbon accumulation and RMF, while increasing height to improve light use efficiency.

Summary: The use of mineral fertilisers can alter soil properties to varying degrees, and the response of the rhizosphere and non-rhizosphere to fertilisers differs. Long-term fertilisation significantly increases the nutrient contents, microbial biomass, and activity in the soil, and it is advisable to apply P fertiliser in the root zone to improve efficiency.

Summary: Bacterial communities in soil play a critical role in carbon and nutrient cycling. This study investigated the assembly and distribution of bacterial communities at different soil depths. The results showed that bacterial diversity and abundance decreased with soil depth due to limited access to carbon and nutrients. The relative abundance of different phyla also varied with soil depth. The study also found that ecological interactions between bacterial taxa increased with depth, leading to reduced functional redundancy. The study provides valuable insights into the assembly processes of bacterial communities in different soil depths.

Summary: Understanding the mechanisms driving biological invasions is crucial for understanding population dynamics, biodiversity, and community assembly. This study conducted a phylogenetic meta-analysis to assess the role of soil biota in plant invasions. The results showed a positive effect of soil biota on plants, with invasive species having a stronger effect compared to natives. The strength of the effect weakened over time since introduction, supporting the predictions of the enemy escape hypothesis.
