EFFECT OF BARLEY YELLOW DWARF VIRUS(BYDV)IN AUTUMN AND SPRING INFECTION ON THE YIELD OF WHEAT AND EPIDEMIOLOGY OF BYDV;

Analysis of Transmission Capabilities of Barley Yellow Dwarf Virus(BYDV) by Schizaphis graminum and Rhopalosiphum padi in Northwest China

It could reduce the wheat productions directly, and transmit the Barley Yellow Dwarf Virus (BYDV) to lead considerable losing indirectly.

As a result, yield loss is serious, in 1966, 1970, 1978, 1983 and 1988, wheat yellow dwarf disease was epidemics in China, and huge yield losses often incurred in many countries planted wheat.

Wheat yellow dwarf disease is a major disease in China.

Transgenic wheat expressing virus-derived hairpin RNA is resistant to Barley yellow dwarf virus;

Preliminary study on transcapsidation between GPV and GAV strains of Barley yellow dwarf virus;

Transgenic wheat resistant to Barley Yellow Dwarf Virus obtained via pollen tube pathway;

Review of BYDV Resistance Breeding in Wheat;

CLONING AND SEQUENCING OF COAT PROTEIN GENE FOR A BYDV PAV CHINESE ISOLATE;

The results show that the heredity effects of resistance to BYDV are additive, dominant and epistatic, and the additive effect is the majority.

According to published nucleotide sequence, ORF4 gene of Barley yellow dwarf virus GPV (BYDV-GPV) was synthesized by reverse transcription-polymerase chain reaction (RT-PCR) and inserted into expression vector pET-5a for overexpression in prokaryotic cells.
