Isolation, Purification, and Biological Activity of a Phytotoxin Produced by Stemphylium solani
Garlic leaf blight caused by Stemphylium solani is a serious disease in vegetable-growing areas of China (28). Symptoms of the disease start as small white spots (1 to 3 mm) enlarging to elongated purple necrotic lesions along the vein, followed by blighting of the leaf tips. Similar symptoms were produced by culture filtrates of S. solani, and a strong correlation was also found between garlic...
متن کاملCharacterization of L-asparagine transport systems in Stemphylium botryosum.
L-Asparagine uptake by Stemphylium botryosum is mediated by two distinct energy- and temperature-dependent transport systems. One permease is relatively specific for L-asparagine and L-glutamine and is present in nutrient-sufficient mycelium. The specific permease shows an optimum pH at 5.2, saturation kinetics (Km = 4.4 x 10(-4) M, Vmax = 1.1 mumol/g per min), competitive gradient of L-asparag...
متن کاملRed fluorescent protein (DsRed2) as a novel reporter in Fusarium oxysporum f. sp. lycopersici.
pAn-DsRed2 vector was constructed for constitutive cytoplasmic expression of the red fluorescent protein (DsRed2) under control of the glyceraldehyde-3-phosphate dehydrogenase gene promoter from Aspergillus nidulans. DsRed2-transformation of two Fusarium oxysporum f. sp. lycopersici strains pathogenic against tomato host resulted in bright red cytoplamic fluorescence of the fungus. The transfor...
متن کاملردیابی و تکثیر ژن های اثرگذار حامل دومین LysMدر ژنوم قارچ F. oxysporum f. sp. lycopersici
During the infection- while the xylem is colonized by the F. oxysporum f. sp. Lycopersici (Fol)- several effector proteins have been secreted into the xylem that suppress the plant’s defense response and enable parasitic colonization. So far, 14 effector proteins have been reported in Fol. However, there are no identified domains in their sequences. LysM effector proteins were identified ...
متن کاملCultural and Physiological Variation Between Isolates of Stemphylium botryosum the Causal of Stemphylium Blight Disease of Lentil (Lens culinaris)
A total of four isolates of Stemphylium botryosum infected lentil were collected from lentil plants showing blight symptoms and grown at different areas of Bangladesh. The isolates were characterized in terms of cultural, morphological and physiological parameters. The isolates varied significantly in their cultural, morphological and physiological traits of colony color, shape, texture, conidi...
