Marker-assisted selection strategies for developing resistant soybean plants to cyst nematode

SNP Marker Assisted Selection for Identification of Fusarium Resistant Melon Plants

Melon is an important crop cultivated in moderate climate regions of the world. One of the most important diseases of this plant is vascular wilt caused by Fusarium oxysporum f.sp. melonis (Fom). Infection of farm by this pathogen can result in huge damage around the world. Development of resistant varieties is the most effective method for disease control. Four races of 0, 1, 2 and 1,2 have be...

Analysis of expressed sequence tags from roots of resistant soybean infected by the soybean cyst nematode.

The soybean cyst nematode (SCN) Heterodera glycines is the most devastating pest of soybean in the U.S.A. The resistance response elicited by SCN in soybean is complex, and genes involved in the response to a large extent are unknown and not well characterized. We constructed cDNA libraries made from mRNA extracted from roots of the resistant soybean Glycine max L. Merr. 'Peking' at 12 h, 2 to ...

Protease inhibitor expression in soybean roots exhibiting susceptible and resistant interactions with soybean cyst nematode.

Protease inhibitors play a role in regulating proteases during cellular development and in plant defense. We cloned and sequenced cDNA encoding six protease inhibitors expressed in soybean roots infected with soybean cyst nematode (SCN) and determined their expression patterns. Four of these protease inhibitors are novel and have not been reported previously. Using RT-PCR, we measured the relat...
