Genes implicated in resistance to soybean cyst nematode infection and methods of their use

摘要

Genes whose expressions are up-regulated or down-regulated in plant roots in response to nematode infection are disclosed. These genes may play an important role in plant defense against SCN infection. Several nematode-inducible promoters have also been identified in plants, which may be used in nematode inducible gene expression construct. Expression of these SCN responsive genes may be manipulated to obtain SCN resistant lines.

1. A transgenic soybean plant generated from a host soybean plant, said transgenic soybean plant comprising a construct comprising a nucleic acid encoding SEQ ID NO:166 operably linked to a heterologous promoter, wherein said transgenic soybean plant has an increased expression level of said protein compared to the host soybean plant and is more resistant to nematode infection when compared to the host soybean plant.
