Climate change is causing more extreme weather patterns and increasing challenges for agriculture. The unusually dry European summer of 2018 caused an 8% drop in cereal production (source: https://ec.europa.eu/info/sites/info/files/food-farming-fisheries/farming/documents/short-term-outlook-autumn-2018_en.pdf). Plants need water for photosynthesis and to maintain turgor pressure; drought-stressed plants wilt, turn yellow, and eventually die. Stomata quickly close during drought stress, limiting water […]

Light is life, especially for plants. It fuels photosynthesis and, when perceived by photoreceptors, directs important developmental programs, including photomorphogenesis and shade avoidance. Red and blue light wavelengths activate phytochrome (phy) and cryptochrome (cry) photoreceptors, respectively, which repress transcription factors that antagonize photomorphogenic development, such as the PHYTOCHROME INTERACTING FACTORs (PIFs). When phys and crys […]
Plants live by the clock. It helps them to predict day and night as well as upcoming seasons, and to decide when it’s time for reproduction. These predictions depend on oscillating processes that involve gene transcription and protein stability, cycling in a period of, for example, 24 h. Environmental factors such as light, temperature, and […]
