The Impact of Soybean Cyst Nematode on Soybean Physiological Parameters: Nitrogen Fixation Activity, Root and Leaf Growth

Soybean cyst nematode (SCN) is an important pathogen of soybean, causing over $1 billion yield loss yearly in the United States. To further understand the pathogen-host relationship between the nematode and soybean, study was conducted to track the real time effects of SCN pathogenesis on nitrogen – fixation activity, as well as root and leaf growth of three soybean lines. This information would provide insights into the physiological effects of nematodes on plants.
