Using chlorophyll fluorescence parameters and antioxidant enzyme activity to assess drought tolerance of spring wheat

The improvement of phenotyping methods is necessary for large-scale screening studies of wheat (Triticum aestivum L.) drought tolerance. The objective of our research was to find out whether it is possible to use chlorophyll (Chl) fluorescence parameters

Metabolite Profiles and Antioxidant Activity of Dendrobium catenatum Under Simulated Wild Cultivation

Food Safety and Health, EarlyView.
Dendrobium catenatum grown under simulated wild cultivation showed significantly higher flavonoids and stilbenes, leading to enhanced antioxidant activity in both leaves and stems compared to facility‐grown plants. Integrated metabolomics, antioxidant assays, and network pharmacology identified Denbinobin as a key multi‐target antioxidant compound ...

Uncovering the Role of the KANADI Transcription Factor ZmKAN1 in Enhancing Drought Tolerance in Maize

Plants
Drought stress causes substantial yield losses in maize, posing a serious threat to food security. Leaf adaxial-abaxial polarity development is closely associated with drought tolerance.

Dehydration induced transcriptomic responses in two Tibetan hulless barley (Hordeum vulgare var. nudum) accessions distinguished by drought tolerance

, 2017
Background: The harsh environment on the Qinghai-Tibetan Plateau gives Tibetan hulless barley (Hordeum vulgare var. nudum) great ability to resist adversities such as drought, salinity, and low temperature, and makes it a good subject for the analysis of

Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

Food Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

The Influence of PEG-Induced Drought Stress on Seed Germination and Seedling Growth Traits of Tetraploid Annual Ryegrass Cultivars

ISPEC Journal of Agricultural Sciences
Drought stress poses a significant challenge to global forage production, particularly under climate change conditions. Identifying cultivars with superior drought tolerance is essential for maintaining productivity in water-limited environments.

The effect of awns on seed yield and germination characteristics in Elymus nutans Griseb.

Grassland Research, EarlyView.
The effect of awns on seed yield. Three‐year field trials demonstrated that awns significantly regulate seed yield components and germination characteristics of Elymus nutans Griseb, laying a theoretical foundation for the breeding of high‐yielding forage varieties and seed production.

Genome‐wide identification of the bZIP transcription factor family in sainfoin (Onobrychis viciifolia Scop.) and expression profiles in response to aluminum stress

Grassland Research, EarlyView.
Sainfoin is an important forage legume with potential for cultivation in stressful environments, but its molecular response to aluminum toxicity remains unclear. This study identified 236 basic leucine zipper (bZIP) transcription factor genes in sainfoin and analyzed their evolutionary features and regulatory potential.
