The June 12 issue of Science has a focus on plants and heat that includes several excellent review and research articles. In a very interesting review, Singh Yadav et al. discuss the complex and fascinating question of how plants sense temperature, emphasizing both the biophysical nature of temperature…

They May 29 issue of Phil. Trans. Roy. Soc. B. similarly addresses the pressing questions of how crop plants will continue to feed the world in spite of the rapidly changing climate. This issue covers some of the same topics as the Science special issue on heat stress but goes beyond heat to cover drought…

Environmental stimuli, such as drought and salinity, alter cellular conditions including apoplastic pH (pHApo) in plants. These stimuli often lead to an elevation in pHApo which is closely associated with cell functions and plant growth. However, the mechanism behind is largely unexplored. A recent study…

Memory—a mysterious cognitive process that retains information over time and shapes future interpretations and actions—is not exclusive to animals. In plants, a similar phenomenon occurs where past exposure to environmental stressors is “memorized,” enabling plants to respond more effectively…

Osmosis, driving water uptake and transport, is crucial for plants. It supports nutrient uptake, turgidity, and overall plant health. In hyperosmotic conditions, caused by drought, salinity, and cold stress, water loss triggers osmotic responses. A key question is: what sensors detect osmotic changes?…

Wheat is a major global crop, but its yields are severely compromised by drought, thus developing varieties with a higher drought tolerance is important. Emmer wheat (Triticum turgidum) is a wheat ancestor that contains more genetic diversity than cultivated varieties, so it can be used in genome wide…

Plants have a remarkable ability to adapt to stress. For many stresses, plants respond to short-term mild exposure by becoming more tolerant to subsequent harsher stresses that would otherwise be lethal; this effect is known as priming. Priming occurs through several mechanisms that can include changes…
