Cyst nematode

Solanoeclepin A (39), a natural hatching agent of potato cyst nematodes, possesses a seven-membered ring in a complex pentacyclic framework. Hiem-stra and coworkers achieved the synthesis of several analogs 42 containing the...

Nematode-host interactions are complex and poorly understood. The relationship between cyst nematodes and their hosts appears to have co-evolved, and as a result there are numerous genes for host resistance that are complemented by nematode parasitism genes (Triantaphyllou, 1987). Different alleles of these genes may interact in various combinations to give... 

The interaction of soybean cyst nematode (SCN) with soybean (Glycine max) has been extensively studied in the United States. This system has been used as a model to dissect the genetics of nematode parasitism, mainly due to the tractability of classical genetic manipulation of the nematode. The remainder of this brief review will focus on the SCN side of the interaction with its host and the progress that has been made in unravelling the complex genetic systems controlling parasitic behaviour. 

The soybean cyst nematode, Heterodera glycines, exists throughout all major soybean-growing regions of the world (Riggs, 1977 Doupnik, 1993).
