The resistant scale, high resistance (HR), moderate resistance (MR), moderate susceptibility (MS) and high susceptibility (HS), were recorded according to reaction of resistance to wheat spindle streak mosaic disease (WSSM) in 560 wheat varieties (lines) tested.

In this paper, Northern blotting analysis revealed that a low molecular weight component of Wheat yellow mosaic virus(WYMV) RNA1 was detected after the twelfth passage of mechanical inoculation in wheat plants associated with exacerbate symptoms displayed and exist stably in the inoculated plants to the 26th passage in the experiment.

The filamentous virus was identified to be wheat yellow mosaic virus (WYMV) as it had a coat protein of 33kD, which was serologically related to WYMV, wheat spindle streak mosaic virus(WSSMV) and barley yellow mosaic virus (BaYMV), but not to barley mild mosaic virus(BaMMV) and.

Wheat yellow mosaic disease caused by Wheat yellow mosaic virus (WYMV) has done severe damage to wheat production in China.

The prokaryotic expression vector pETWCP containing wheat yellow mosaic virus (WYMV) coat protein (CP) gene was constructed by cloning the CP gene into pET-30a(+) and transferred into E.

The sequence analysis revealed that there were some nucleotide differences in CP genes of wheat yellow mosaic virus (WYMV) from Dengzhou city in Henan, Yangzhou city in Jiangsu , Yaan city in Sichuan, Zhouzhi county in Shaanxi province of China.

Wheat yellow mosaic virus (WYMV) coat protein gene, WYMV-72kD protein gene, WYMV-NIb protein gene, human 2-5A-RNase L gene were delivered into Wheat calli induced from immature embryos by others in our lab from 1999 to 2002.

The distribution regions of BaYMV, WYMV(WSSMV) ,and WSBMV in all barley and wheat ecological districts,including 20 provinces,cities and regions,and 116 counties/cities, were investigated in China from 1990 to 1995.
