Interpretive Summary: The soybean cyst nematode (SCN) is the most damaging pathogen of soybean. It causes almost $1 billion in soybean yield losses annually in the United States. However, there are no soybean cultivars available that are resistant to all SCN populations. Therefore, much research is being conducted to genetically engineer soybean that is resistant to SCN. It is necessary to control the expression of genes by using gene promoters, to keep the DNA construct from being expressed at the wrong place or at the wrong time. Here we describe the expression of gene promoters in soybean roots during nematode attack. These promoters may be useful to scientists engineering soybean with resistance to SCN, because they control the expression of DNA constructs in the root during nematode invasion.

Technical Abstract: The soybean cyst nematode (SCN; Heterodera glycines), an obligate parasite of plants, is the most damaging pathogen of soybean, causing $469 to $818 million in soybean yield losses annually in the United States. However, there are no soybean cultivars available that are resistant to all SCN populations. Therefore, much research is being conducted to genetically engineer soybean cultivars for resistance to SCN. Here we describe gene promoters that may be useful in expressing DNA constructs in the soybean root during nematode attack.
