Sustainability, Journal Year: 2025, Volume and Issue: 17(5), P. 2221 - 2221

Published: March 4, 2025

Climate change has increased the frequency of extreme droughts and floods in China, threatening agricultural production food security. However, impacts these precipitation events on crops (maize, wheat, rice) during key growth stages remain poorly understood. To address this, we developed a three-step analytical framework: First, used transpiration data to identify critical crop across China. Then, applied 10-day standardized evapotranspiration index (SPEI) quantify drought wetness conditions each phase. Finally, integrated into an XGBoost model assess relationship between weather yield fluctuations. The results show that maize is most sensitive water variability both development mid-season stages, while wheat particularly vulnerable rice mainly affected by stress mid-season. Extreme risks are highest Northeast Plain, North China southern concentrated middle lower Yangtze River basin southeastern coastal regions. Notably, significantly more pronounced than those associated with wetness. These findings highlight urgent need for targeted strategies promote sustainable development.

Mitigating Water Stress in Plants with Beneficial Bacteria: Effects on Growth and Rhizosphere Bacterial Communities

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(4), P. 1467 - 1467

Published: Feb. 10, 2025

Climate change has reshaped global weather patterns and intensified extreme events, with drought soil salinity negatively impacting the yield quality of crop production. To mitigate detrimental effects stress, introduction beneficial plant growth-promoting rhizobacteria (PGPR) proven to be a promising approach. In this study, we evaluated synthetic microbial community (SynCom) comprising bacterial strains belonging species Bacillus velezensis, Pseudomonas simiae, P. salmasensis, Glutamicibacter halophytocola, Leclercia sp., which have been demonstrated promote tomato growth both individually collectively. The SynCom most its individual were shown polyethylene glycol (PEG)-induced stress in vitro Arabidopsis thaliana seedlings, either by reducing alterations xylem elements or promoting formation new strands. greenhouse trial, drenching two strains, B. velezensis PSE31B salmasensis POE54, improved water response soilless-grown plants under 40% reduced irrigation regime. Additionally, treatments positively influenced diversity rhizosphere communities, distinct changes composition, suggest treatment-specific interplay between introduced native microbiome. These findings highlight potential consortia PGPR as sustainable tools improve resilience abiotic stresses.

Electromagnetic Properties of Natural Plant Leaves for Eco-Friendly and Biodegradable Substrates for Wireless IoT Devices

Sensors, Journal Year: 2025, Volume and Issue: 25(4), P. 1118 - 1118

Published: Feb. 12, 2025

Today, innovative engineering solutions, including IoT devices, enable the precise monitoring of plant health and early detection diseases. However, lifespan devices used for real-time environmental or parameters in precision agriculture is typically only a few months, from planting to harvest. This short creates challenges managing e-waste generated by smart agriculture. One potential solution reduce volume impact use more environmentally friendly biodegradable materials replace non-degradable components (substrates) currently structure devices. In this study, we estimate electromagnetic properties at 2565 MHz leaves three widely grown crops: winter wheat, corn, sunflower. We found that wheat sunflower have values real part relative permittivity ranging about 33 69 (wheat) 13 32 (sunflower), respectively, while corn exhibits value 33.5. Our research indicates position leaf on stem its distance soil significantly affect These relationships, however, are not evident leaves.

Dual Controls of Shrub Encroachment in Semiarid Grasslands: Ectomycorrhizal Fungi and Soil Nitrogen Cycling

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: March 19, 2025

ABSTRACT Shrub encroachment significantly impacts biodiversity and ecosystem functions in grassland ecosystems. Soil microbial communities may play a key role this process. Previous studies have focused on plant competition soil abiotic factors, but the specific biological mechanisms by which microbiota drive shrub remained poorly understood. Through integrated vegetation surveys high‐throughput sequencing of across gradients Inner Mongolia, we assessed composition functional genes importance value. We found that value closely correlated with limited resources, including water nitrogen (N), during encroachment. Ectomycorrhizal (EcM) fungi were recruited semishrub Artemisia ordosica , increasing its competitiveness under conditions resource scarcity. Changes community affected N cycling reducing abundance involved fixation, nitrification, nitrate assimilation. Concurrently, shrubs preferred (NO 3 − ‐N) over herbaceous plants nutrient‐poor environments. The was facilitated EcM fungi, enabling them to thrive N‐deficient arid environments preferentially utilize NO ‐N. Our findings establish novel microbial‐mediated pathway driving encroachment, fungal symbionts enable host alleviate limitations through modified nutrient acquisition strategies. These results suggest targeted manipulation associations could inform restoration strategies shrub‐encroached grasslands highlight need for management approach accounts dynamics.
