Aspects of adaptive answering formation in virus-host plant pathosystem for different wheat cultivars under...

Investigations of prolonged clinorotation effect on some morphological and physiological parameters under Wheat streak mosaic virus WSMW-infection of Apogee and Lada wheat cultivars were carried out. Experiments were held on universal clinostat CYCLE-2. Clinorotation caused changing of WSMV virions shape and reducing of the virus reproduction. Apogee wheat plants grown under two stress factors (infection and clinorotation) produced more kernels than stationary (motionless) plants, but the average weight of kernel was lower. Under clinorotation changes in host plant-virus system take place and adaptive reactions for simulated microgravity conditions form. These lead to reduction of potyvirus replication.
