Suitability of drought tolerance indices for selecting alfalfa (Medicago sativa L.) genotypes under organic farming in Austria [PDF]

, 2012
In eastern Austria, alfalfa is usually grown as a rainfed crop in crop rotations in organic farming systems, where year-to-year rainfall fluctuations cause different levels of drought stress. To identify the suitability of different alfalfa genotypes and

Single‐Cell Transcriptome Reveals Aquaporin‐Mediated Carbon Nanosol‐Induced Growth Promotion of Plants

Advanced Science, EarlyView.
Carbon nanosol (CNS) exhibits rapid root penetration capacity, enhancing plant growth through boosting stomatal density and antioxidative enzyme activity. Single‐cell transcriptomic profiling uncovers cell type‐specific gene expression patterns and developmental trajectories during CNS‐mediated growth promotion.

Predisposition of trees to drought stress by ozone [PDF]

Tree Physiology, 1999
This paper reviews research on the effects of ozone on stomatal behavior, and draws attention to the direct link between stomatal function and air pollution. Contradictory results concerning the effects of air pollutants on stomatal activity are attributed to the use of univariate statistical treatments of data.

Allelic diversity at orthologous candidate genes for drought tolerance in cereal crops: Example of the ASR gene family [PDF]

, 2008
Drought is a major abiotic stress. Many candidate genes have been proposed during the last years to explain aspects of tolerance to drought stress, for a specific crop and in a specific environment.

Farmers' stress and coping in a time of drought

Rural and Remote Health, 2012
Farmers as a group have unique attitudes, sources of stress and a heightened risk of suicide. In the context of a prolonged drought and associated stress and increased risk of mental-health problems, this study provides an insight into the levels of psychological distress experienced by different demographic groups within the Australian farming ...

Electronic Nanomaterials for Plants: A Review on Current Advances and Future Prospects

Advanced Electronic Materials, EarlyView.
Global food security faces mounting challenges from climate change and rapid population growth. This review highlights the pivotal role of electronic nanomaterials–including metals, metal oxides, and carbon‐based structures–in enhancing plant photosynthesis, nutrient uptake, and stress resilience. Furthermore, it explores how emerging platforms such as
