A new study provides updated guidelines for accurately estimating plant genome size using flow cytometry. Researchers identified sources of error—such as tissue type, buffer choice, and fluorochrome variations—that can affect accuracy by ±29% or more. Revised reference standards and best…

Plants use pigments called phytochromes to sense light and temperature, adjusting growth and metabolism accordingly. Rising temperatures, however, disrupt these processes. Researchers found that under red light, phytochrome responses vary with temperature and light intensity, potentially allowing precise control of…
