  摘要：Continued greenhouse gas emissions will accelerate global warming and intensity of heat waves, which already harm crop productivity. From the stability of key enzymes to canopy processes, photosynthesis is affected by temperature. All crops suffer declines in photosynthetic rate when temperatures cross critical thresholds, with irreversible losses typically occurring above 40 degrees to 45 degrees C. Protective measures within plants can be induced by growth at elevated temperatures but not fr...

  摘要：Dopamine (DA) plays a crucial role in a variety of brain functions through intricate interactions with other neuromodulators and intracellular signaling pathways. However, studying these complex networks has been hindered by the challenge of detecting multiple neurochemicals in vivo simultaneously. To overcome this limitation, we developed a single-protein chemigenetic DA sensor, HaloDA1.0, which combines a cpHaloTag-chemical dye approach with the G protein-coupled receptor activation-based (G...

  摘要：The efflux of carbon dioxide (CO2) from woody stems, a proxy for stem respiration, is a critical carbon flux from ecosystems to the atmosphere, which increases with temperature on short timescales. However, plants acclimate their respiratory response to temperature on longer timescales, potentially weakening the carbon-climate feedback. The magnitude of this acclimation is uncertain despite its importance for predicting future climate change. We develop an optimality-based theory dynamically l...

  摘要：In temperate regions experiencing rapid ocean warming, kelp forests are being replaced by chemically rich turf algae. However, the extent to which these turf algae alter the surrounding chemical environment or affect the rebound potential of kelp forests (through chemically mediated interactions) remains unknown. Here, we used underwater visual surveys, comprehensive chemical profiling, and laboratory experiments to reveal that turf algae release bioactive compounds into the water that fundame...
