Plants are known to be highly responsive to environmental heterogeneity and normally allocate more biomass to organs which grow in richer patches. However, recent evidence demonstrates that plants can discriminately allocate more resources to roots that develop in patches with increasing nutrient levels, even when their other roots develop in richer patches. Responsiveness to the direction and steepness of spatial and temporal trajectories of environmental variables might enable plants to increase their performance by improving their readiness to anticipated resource availabilities in their immediate proximity. Exploring the ecological implications and mechanisms of trajectory- sensitivity in plants is expected to shed new light on the ways plants learn their environment and anticipate its future challenges and opportunities.

Aims: The increasing antimicrobial resistance, particularly in Acinetobacter baumannii, complicates the treatment of infections, leading to higher morbidity, mortality, and economic costs. Herein, we aimed to determine the in vitro antimicrobial, synergistic, and antibiofilm activities of colistin (COL), meropenem, and ciprofloxacin antibiotics, and curcumin, punicalagin, geraniol (GER), and linalool (LIN) plant-active ingredients alone and in combination against 31 multidrug-resistant (MDR) A. baumannii clinical isolates.

The Asiatic apple leafminer, Phyllonorycter ringoniella (Matsumura), is a significant secondary pest of apple trees in Northeast Asia. To better understand its population dynamics, a population model based on temperature-developmental relationships was constructed. This model includes three sub-models: spring emergence, immature stage transition, and adult oviposition.

Salicylic acid (SA) is a critical phytohormone involved in plant growth, development, and defense responses, making its precise quantification essential for both agricultural management and environmental monitoring. Here, we report a novel label-free near-infrared aptasensor (NIRApt) for the rapid and sensitive detection of SA, utilizing a rationally selected triphenylmethane (TPM) dye. Through systematic screening, ethyl violet (EV) was identified as the optimal fluorophore, showing pronounced fluorescence enhancement upon binding to a SA-specific aptamer.

Pollutants from industrial emissions and traffic accumulate in urban soils as road dust, carrying heavy metals (HMs) posing ecological and health risks. Magnetic susceptibility (MS), sensitive to ferromagnetic minerals, enables rapid HM contamination assessment. This study developed the Modified Dual-Threshold MS Evaluation Plot for Soil Contamination (M-Plot) using χ and χ% indices.

In this study, we evaluated the antibacterial activities of plant essential oils (EOs) from the Lamiaceae family against Agrobacterium tumefaciens to find new eco-friendly antimicrobials. Thymus vulgaris L. (thyme white) EO demonstrated the most potent fumigant antibacterial activity among these.
