Summary: This study found that different species have significant differences in blue light-induced stomatal responses, with increased stomatal conductance reducing photosynthetic limitation but increasing water loss. Additionally, the synergistic effect of blue light and respiration plays an important role in driving rapid stomatal movements, especially when photosynthesis is limited.

Summary: The study explored the effects of different plant growth-promoting bacteria (PGPB) on rice productivity and quality under ozone stress, revealing that inoculation with specific bacteria could mitigate the negative impacts of elevated ozone levels on rice production. These bacteria were found to enhance indole-3-acetic acid (IAA) production, photosynthesis capability, and ascorbic acid content in rice, leading to improved yields and quality.

Summary: The study found that under copper stress, Phragmites australis showed decreased chlorophyll content, inhibited expression of important photosynthesis proteins, and reduced photosynthesis. However, the levels of ascorbic acid and proline increased, limiting copper migration within the plant. These findings provide insight into the tolerance and repair mechanisms of plants in response to heavy metal pollution.

Summary: As global climate warms, increasing leaf temperatures have a significant impact on tree physiology and the interaction between leaf and air temperatures in forests. By warming leaves in two mature evergreen forests, researchers found that higher leaf temperatures lead to reduced stomatal conductance and net photosynthesis, potentially weakening the land carbon sink in tropical and temperate forests.

Summary: The study found that shaded leaves have greater photosynthetic capacity per unit irradiance and smaller marginal carbon revenue of water compared to sunlit leaves, contradicting optimization theory. The model adjusted carbon partitioning, nitrogen partitioning, and leaf water potential to maximize carbon profit or canopy photosynthesis, revealing that shaded modules should have larger photosynthetic capacity per unit irradiance and smaller marginal carbon revenue of water. This was partly due to radiation-driven differences in evaporative demand and differences in hydraulic conductance arising from the need to balance returns on stem carbon investment between modules.

Summary: In this study, the anti-tumor effect of ascorbic acid combined with metformin in prostate cancer was evaluated. It was demonstrated that ascorbic acid inhibits prostate cancer cells proliferation by generating reactive oxygen species (ROS), and metformin enhances the anti-tumor effects of ascorbic acid. Mechanistically, metformin reduces oxygen consumption rate and NADP+/NADPH value in prostate cancer cells, thereby increasing the ROS content induced by ascorbic acid. Moreover, ascorbic acid inhibits p-AKT signaling in a ROS-dependent pathway, leading to inhibition of p-mTOR expression, and metformin inhibits the p-mTOR expression by activating the AMPK signaling pathway, exerting a synergistic effect on tumor suppression with ascorbic acid. Furthermore, metformin improves tumor oxygenation, and the combined treatment effect of ascorbic acid and metformin were demonstrated in a xenograft model of prostate cancer.

Summary: Selection for yield and agronomic traits between 1958 and 2012 in Australian wheat has improved adaptation to early-season drought, leading to increased grain yield. Newer varieties displayed more efficient responses to drought stress, with shorter time to flowering, reduced leaf area, and maintained higher photosynthetic rates per unit leaf area compared to older varieties.

Summary: Although growth stimulation was observed in some plants at low doses of arsenic, few studies have examined this phenomenon in detail. This study investigated the effects of different concentrations of arsenic on the growth and physiological parameters of two maize cultivars. The results showed that one cultivar, MvNK 333, had a higher tolerance to arsenic and exhibited increased shoot elongation, biomass, and water content at specific doses of arsenic. The overall findings suggest that the stimulatory effect of low doses of arsenic may represent an adaptation mechanism related to water content regulation.

Summary: The study aimed to explore the differences in nutrient absorption, growth, and photosynthetic characteristics of different tomato cultivars under different VPDs. The results showed that tomato cultivars differ in their sensitivity to VPD, with cultivars with lower stomatal sensitivity showing increased levels of certain nutrients in certain organs under high VPD conditions, while cultivars with higher stomatal sensitivity demonstrated opposite trends.

Summary: The study found that the growth of Microcystis aeruginosa, a bloom-forming cyanobacterium, was initially inhibited by perfluorooctanoic acid (PFOA). However, the inhibition gradually decreased and stabilized over time. The self-adaptive mechanisms of the microalgae to PFOA exposure included antioxidant pathways, energy transfer and distribution of photosystems, and repair of specific complexes.

Summary: This study investigated the role of H2O2 in tomato ripening and found that H2O2 participates in this process through its association with the ethylene signaling pathway. The experiments showed that high irradiance treatment enhanced H2O2 production and accelerated fruit ripening. These results may be attributed to changes in the expression of H2O2-related genes and ethylene-related genes.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
