Summary: The study focused on screening drought-tolerant sugarcane cultivars using PEG as a stressing agent. Results showed varying responses in different cultivars, with Mex 69-290 exhibiting tolerance to osmotic stress. Overall, total protein content decreased while dry matter, proline, and glycine-betaine contents increased with higher PEG concentrations. This suggests Mex 69-290 could be a suitable choice for rainfed cultivation with low water availability.

Summary: Halotolerant species naturally occur in environments with excess toxic ions, making them interesting for study. The cyanobacterium Halothece sp. PCC 7418 (Halothece) was used to explore stress-responsive regulatory mechanisms. RNA sequencing was performed to examine the effects of five different stimuli on Halothece transcriptomes. The study found both common and stress-specific transcriptional responses to diverse stresses. Osmotic stress elicited the largest set of differentially expressed genes (DEGs), while salt- and osmotic-responsive regulatory mechanisms shared common pathways. Salt stress specifically upregulated genes involved in photosynthesis, two-component systems, transcription, protein-protein interactions, and lipid biosynthesis. Glycine betaine (GB) synthesis enzymes and transporters were also upregulated under salt stress. GB and mycosporine-2-glycine (M2G) accumulation was observed under salt or osmotic stress.

Summary: This study aimed to investigate the effect of dietary betaine (Bet) and glycine (Gly) alone or in combination on productive performance, stress response, liver health, and intestinal barrier function in broiler chickens under heat stress conditions. The results showed that supplementation of betaine, glycine, or their combination improved the body weight and growth rate of broiler chickens, but the effect was still lower compared to the thermoneutral condition.

Summary: This study aimed to evaluate the tolerance of five white poplar clones to the presence of polyethylene glycol (PEG 6000) and found that high concentrations of PEG 6000 resulted in decreased morphological and photosynthetic pigment values, while total phenolic content, proline and glycine betaine levels, and antioxidant activity increased. Clone L-80 showed better performance in most tested parameters.

Summary: The study identified a microorganism called DCMF that can transform toxic dichloromethane into environmentally benign acetate in anaerobic environments. Through stable carbon isotope experiments, it was shown that DCMF assimilates carbon from DCM and bicarbonate via the Wood-Ljungdahl pathway. DCMF is the first anaerobic population known to degrade dichloromethane, while also metabolizing non-chlorinated substrates.

Summary: Urban floodwater poses significant risks to public and environmental health due to the presence of microbial pathogens and overflow of wastewater treatment systems. A study found that floodwater after periods of drought had a 2.5-fold higher abundance of antibiotic resistance genes and virulence factors compared to floodwater after regular rain events. This study also identified previously undescribed species that become mobilized after flooding events, increasing the public health risk.

Summary: The application of green manure in northern China has a positive impact on agriculture, improving soil quality, enhancing microbial activity, and increasing crop yields. Different types of green manure have varying effects on nutrient content, with legume green manure showing greater potential for nitrogen enhancement and non-legume green manure for potassium enrichment. It is a valuable agricultural practice that can be beneficial for sustainable crop production in the region.

Summary: This study compared the physiological processes facilitating growth in low-N-tolerant and low-N-sensitive millet cultivars under different nitrogen fertilization levels. Low nitrogen treatments resulted in decreased photosynthetic capacity and reduced grain yield, while low-N-tolerant cultivars exhibited improved growth and resource utilization. The results demonstrated how low-N-tolerant cultivars achieved higher grain yields under low N conditions in the field.

Summary: The study suggests that Bothriochloa ischaemum responds more positively to periodic increases in soil water availability compared to Lespedeza davurica, indicating that the abundance of B. ischaemum could increase in relatively wet seasons or periods of abundant rainfall. The mixture ratio of 10:2 (B. ischaemum to L. davurica) was found to be the most compatible combination for improved biomass production, water use efficiency (WUE), and relative yield totals (RYTs) across all soil water treatments.

Summary: This study investigated the mechanism of melatonin in mitigating chromium toxicity in maize plants using transcriptomic and physiological approaches. The results showed that melatonin treatment significantly reduced the chromium content in leaves, while the chromium content in roots remained unchanged. Further analysis revealed that melatonin alleviated chromium-induced oxidative stress by affecting cell wall polysaccharide biosynthesis, glutathione metabolism, and redox homeostasis. These findings highlight the important role of melatonin in alleviating chromium toxicity in maize.

Summary: This study investigated the variations in Cd accumulation and tolerance among four maize genotypes with different root morphology, and found a positive correlation between root characteristics and Cd accumulation. Genotypes Shengrui999 and Zhengdan958 showed higher Cd accumulation and tolerance under Cd stress. Cd toxicity led to membrane degradation and reduced starch reserves in maize plants. The greater tolerance of Shengrui999 and Zhengdan958 may be attributed to factors such as root biomass, shallower root depth, higher Cd content, and accumulation of osmolytes and antioxidant activities.
