Development of an automated system for extraction and quantification of soybean cyst nematode (SCN) eggs and cysts
Soybean is the world’s foremost source of vegetable protein and oil. In order to meet the growing global soybean demand for feed and biodiesel, soybean production in the US will need to increase by 28 percent over the next decade. Addressing this demand necessitates increasing efficiency of soybean …

Automated soybean cyst nematode extraction unit
The soybean cyst nematode (SCN) is a plant parasitic roundworm of soybeans responsible for an estimated $0.7-1.2 billion reduction in annual yield loss. In order to manage yield loss due to SCN, soybean producers employ a nematode management plan which utilize extensive soil sampling to assess SCN …

Characterization of 16B09 and 2D01 effector proteins in cyst nematodes
Cyst nematodes use stylet-secreted effector proteins to modify a selected host cell into an elaborate feeding cell. The function of the novel effector proteins 16B09 and 2D01 from the soybean cyst nematode (SCN) Heterodera glycines and sugar beet cyst nematode (BCN) H. schachtii was studied. This …

Characterization of a soybean BAG gene and its potential role in nematode resistance
Plants resistant to the soybean cyst nematode (SCN) mount a hypersensitive cell death-like response upon nematode feeding, but the genes regulating this process are not known. Laser-assisted microdissection of nematode feeding cells coupled with microarray analysis identified a soybean gene …

The role of heterodera glycines biotin synthase in the nematode-soybean interactions
Heterodera glycines, the soybean cyst nematode (SCN), is a plant-parasitic nematode capable of manipulating host plant biochemistry and development. Many studies have shown that the nematode has acquired genes from bacteria via horizontal gene transfer events (HGTs) that have the potential to …
