Proteomic and Physiological Analysis of the Response of Oat (Avena sativa) Seeds to Heat Stress under Different Moisture Conditions

open access: yesFrontiers in Plant Science, 2016
Seeds lose their viability when they are exposed to high temperature and moisture content (MC) during storage. The expression and metabolism of proteins plays a critical role in seed resistance to heat stress.

Optimizing inorganic nitrogen extraction method to evaluate alternative cropping strategies

open access: yesAgronomy Journal, Volume 117, Issue 4, July/August 2025.
Abstract Nitrogen (N) is essential for all land plants, but crops use only ∼50% of the fertilizer N, the rest being lost to the environment. Accurate estimation of soil N and optimizing N fertilizer management are critical for enhancing agricultural sustainability and profitability.

Floodplain land use gradients have a stronger effect on soil microbial enzyme activity than spatiotemporal variability

open access: yesEcosphere, Volume 16, Issue 7, July 2025.
Abstract Climate change is leading to flood events with higher frequency and longer duration. Changes in seasonal flooding that affect water saturation of soils can impact soil microbial extracellular enzyme activity (EEA) that mediates nutrient and carbon cycling.

Live fast, die young? Day‐ and night‐warming affect the growth, survivorship, and behavior of caterpillars in the field

open access: yesEcology, Volume 106, Issue 7, July 2025.
Abstract While both daytime and nighttime temperatures are increasing with climate change, few studies have experimentally investigated their differential effects under field conditions. We conducted a factorial field experiment examining how day‐ and night‐warming impact the growth, survivorship, and behavior of cabbage white caterpillars (Pieris ...

Oat Cover Crop Integration in Alfalfa‐Tall Fescue Mixed Grasslands: Optimizing Sowing Ratios and Spatial Arrangements for Enhanced Productivity and Weed Suppression

open access: yesFood and Energy Security, Volume 14, Issue 4, July/August 2025.
ABSTRACT The integration of cover crops during forage establishment represents a widely adopted agronomic strategy to suppress weed emergence, enhance stand establishment, and improve grassland community stability. In this study, a two‐year field experiment (2023–2024) was conducted in Jiaozhou, Shandong Province, China, to evaluate the effects of ...
