Why plant cells need heme: Hidden signal reshapes photosynthesis gene control

For plants, light is an important environmental factor not only as a source of energy for photosynthesis, but also as a signal for capturing environmental information. Light signals are sensed by photoreceptor proteins called phytochromes. The amino acids that make…

Scientists uncover how protein helps plants grow in early stages

For most of their lives, plants get their energy from photosynthesis. But during the seed to seedling stage when they can’t absorb light just yet, they rely on other sources, like fatty acids. To process the fatty acids, plant cells,…
