Why Does Ethylene, an Important Plant Hormone, Accumulate in Oxygen-Depleted Soils? A newly discovered methionine biosynthesis pathway found in many bacterial species results in the production of ethylene and seems to be key. To identify this new metabolic pathway, a team of scientists from multiple universities and two national laboratories grew freshwater bacteria in soil … Continue reading Why Does Ethylene, an Important Plant Hormone, Accumulate in Oxygen-Depleted Soils?
