traditionally, in suburbs of tabriz city, northwest iran (gps 38˚06΄n, 46˚15΄e, mean temperature of 6.6-20.0°c, sandy loam soil type), different types of vegetables including cabbages have been cultivated for many years. the cabbage cyst nematode, heterodera cruciferae was reported as one of the plant parasitic nematodes infecting kohlrabi (brassica oleracea l. var. gongylodes) and white cabbag...

Sonchus eruca and Sonchus asper were analyzed for their chemical evaluation, vitamins and bioactive secondary metabolite. The results revealed the presence of bioactive constituents comprising alkaloids (1.24 to 1.34 mg/100 g), saponins (1.46 to 1.72 mg/100 g), flavonoids (1.61 to 1.34mg/100 g), phenols (1.32 to1.44 mg/100g), saponins (0.12 to 0.41mg/100 g) and tannins (0.02 to 0.61 mg/100g). T...

The genomic region encompassing the L protein gene and a small open reading frame (ORF 6) of Rice yellow stunt virus (RYSV) has been sequenced, thus completing the nucleotide sequence of the RYSV genome. The genome organization of RYSV is unique in the rhabdoviruses because it contains two additional genes when compared to the basic gene order of the family Rhabdoviridae: Phylogenetic analysis ...

ABSTRACT Overwintering of tobacco thrips, Frankliniella fusca, was investigated on common winter annual host plants infected with Tomato spotted wilt virus (TSWV). Populations of tobacco thrips produced on TSWV-infected plants did not differ from those produced on healthy plants, whereas populations varied greatly among host plant species. The mean per plant populations of F. fusca averaged 401...
