Researchers improve seed nitrogen content by reducing plant chlorophyll levels

January 3, 2024

Chlorophyll plays a pivotal role in photosynthesis, which is why plants have evolved to have high chlorophyll levels in their leaves. However, making this pigment is expensive because plants invest a significant portion of the available nitrogen in both chlorophyll and the special proteins that bind it. As a result, nitrogen is unavailable for other processes. In a new study, researchers reduced the chlorophyll levels in leaves to see if the plant would invest the nitrogen saved into other process that might improve nutritional quality.

Fluorescent light clarifies relationship between heat stress, crop yield

May 24, 2021

Scientists report that it is possible to detect and predict heat damage in crops by measuring the fluorescent light signature of plant leaves experiencing heat stress. If collected via satellite, this fluorescent signal could support widespread monitoring of growth and crop yield under the heat stress of climate change, the researchers say.
