Summary: Chlorophyll fluorescence can be used as a proxy for photosynthesis in boreal forests. This study measured the spectral chlorophyll fluorescence in leaves of three dominant evergreen species in the boreal ecosystem and analyzed the correlations with other traits to understand the spatial and temporal variation in chlorophyll fluorescence. The findings suggest that the diversity of species and light environments within an ecosystem generate baseline variation in leaf spectral chlorophyll fluorescence and contrasting seasonal photosynthetic acclimation patterns.

Summary: In this study, the effects of rainfall changes on the photosynthetic characteristics and antioxidant system of Gymnocarpos przewalskii were investigated. Results showed that increased rainfall led to significant increases in the net photosynthetic rate and transpiration rate. Decreased rainfall resulted in limitations in photosynthesis caused by stomatal and non-stomatal factors. Furthermore, reduced rainfall led to decreased chlorophyll content, maximum photochemical efficiency of PSII, and steady-state optical quantum efficiency, as well as increased production of reactive oxygen species. Enhanced antioxidant enzymes helped alleviate the damage to the photosynthetic apparatus. This study improves our understanding of the adaptive strategies of desert plants under future precipitation changes.

Summary: SC and NT are two different modern orchard management systems in Taiwan for sustainable citrus orchard development. SC showed higher physiological parameters like Rd, Qy, LCP, Amax, and Fv/Fm compared to NT, especially in fall and winter. Pn, Gs, ETR, NPQ, and Fv/Fm values were higher in spring and summer compared to fall and winter, with positive correlations between Pn and Gs under both NT and SC in all seasons, and significant negative relationships between ETR and NPQ under NT in fall and winter.

Summary: This study compared the cultivation performance of microalga Chlamydopodium fusiforme in two types of outdoor units, thin-layer cascade (TLC) and raceway pond (RWP), for biomass production at a large scale. The results showed that both units could be monitored using photosynthesis measuring techniques and the microalgae grew well in a semi-continuous regime. The RWP had significantly higher biomass productivity compared to the TLC. Overall, the RWP was considered more suitable for scale-up due to its higher productivity, lower costs, smaller land area requirement, and lower carbon depletion and oxygen build-up.

Summary: Symbiodiniaceae live in symbiosis with corals. Increased global temperature affects algae, disrupting symbiosis and causing coral bleaching. Heat tolerance is determined by the species harbored by coral hosts. A study on different strains of Symbiodiniaceae revealed a strain-specific fluorescence wave phenomenon related to cyclic electron transport, potentially important for heat stress tolerance.

Summary: This study analyzed the influencing factors of cropland soil acidification using the example of cropland in the Sichuan Basin of China. The results showed that precipitation was the main factor causing soil acidification. Additionally, soil pH decrease was primarily buffered by soil carbonates and secondarily by soil CEC, with soil carbonates becoming the main buffering agent when their content exceeded 36.76 g kg(-1). These findings emphasize the importance of formulating precipitation-based optimizing agronomic management practices to prevent or mitigate cropland soil acidification.

Summary: The impact of atmospheric deposition of cadmium (Cd) in cereal crops has raised global concerns. In this study, the effect and mechanism of rice in response to leaf Cd exposure were investigated using stable isotopes and a lignin-increased rice mutant. The results showed that enhanced lignin content effectively inhibited Cd transportation in plant tissues, leading to higher Cd tolerance and increased grain yield. These findings provide valuable insights into the molecular and physiological mechanisms of enhanced lignin regulating foliar Cd absorption and yield in rice.

Summary: Salicylic acid (SA) can alleviate arsenic (As) damage and reduce As accumulation in rice. SA protects rice from oxidative damage caused by As by increasing antioxidant enzyme activity and accelerating the response of the antioxidant cycle system. Additionally, SA decreases As accumulation in rice by regulating the expression of genes encoding As transporters.

Summary: Long-term intensive fertilization is a global practice that alters soil microbiome and affects the resilience of soil multifunctionality to biodiversity loss. This study found that organic fertilization promotes the resilience of both single functions and soil multifunctionality compared to mineral fertilization. Bacterial diversity is significantly and positively related to multifunctionality, and the diversity-multifunctionality relationships are stronger in organically fertilized soil.

Summary: Long-term nitrogen fertilization inhibits soil respiration and increases straw-induced priming effect, decreasing microbial biomass and altering microbial diversity and co-occurrence patterns. The oligotroph-to-copiotroph ratio of bacterial indicator species decreases in the early stage of straw decomposition but increases in the later stage, leading to enhanced microbial investment in extracellular enzymes and nitrogen demand, and consequently stronger nitrogen mining process and priming effect.

Summary: Long-term intensive fertilization can greatly alter soil properties and microbial diversity. In this study, we manipulated microbial alpha-diversity to investigate the effects of biotic and abiotic factors on soil microbial mediated functions (MMF). We found that organic fertilization enhanced the resilience of bacterial assemblages to biodiversity loss and increased the positive relationship between soil MMF and bacterial diversity. Factors including diversity and microbiome complexity accounted for 43% of the variation in MMF. Our study highlights the importance of fertilization-induced shifts in network complexity and microbial life strategies for maintaining stable MMF and suggests the need for organically based strategies to mitigate the negative impacts of biodiversity loss on agroecosystem functions.

Summary: This study investigated the effects of crop domestication on root functional traits and trait plasticity in response to neighboring plants. The authors found that wild barley had higher root functional traits and acid phosphatase activity, but lower root exudation of carboxylates and mycorrhizal colonization compared to domesticated barley under low P supply. Wild barley exhibited larger plasticity in root traits, while domesticated barley showed greater plasticity in root exudates and mycorrhizal colonization. The combination of wild barley and faba bean showed higher P uptake benefits under low P supply. These findings provide valuable insights for barley breeding and species selection to enhance P uptake.

Summary: This research aimed to uncover the detoxification mechanisms of rice in response to Cd stress through physiological, transcriptomic, and molecular approaches. The results showed that Cd stress inhibited rice growth, caused Cd accumulation, H2O2 production, and cell death. Transcriptomic sequencing revealed that glutathione and phenylpropanoid were the major metabolic pathways under Cd stress. Physiological studies demonstrated increased antioxidant enzyme activities, glutathione, and lignin contents under Cd stress. q-PCR results showed upregulation of genes related to lignin and glutathione biosynthesis, and downregulation of metal transporter genes in response to Cd stress. Further pot experiment confirmed the causal relationship between increased lignin and reduced Cd in rice.
