Accentuation of Satsuma Dwarf Symptoms by Seedling-Yellows Virus

Accentuation by Catecholamines

Background. Efficient early diastolic filling is essential for normal cardiac function. Diastolic suction, as evidenced by a decreasing left ventricular pressure during early filling, could result from restoring forces (the release of potential energy stored during systolic deformation) dependent on myofilament relaxation. Although these restoring forces have been envisioned within individual m...

The satellite RNA of barley yellow dwarf virus-RPV is supported by beet western yellows virus in dicotyledonous protoplasts and plants.

The subgroup II luteovirus barley yellow dwarf virus-RPV (BYDV-RPV) acts as a helper virus for a satellite RNA (satRPV RNA). The subgroup II luteovirus beet western yellows virus (BWYV) and the ST9-associated RNA (ST9a RNA), a BWYV-associated RNA that encodes a polymerase similar to those of subgroup I luteoviruses, were assayed for their ability to support replication of satRPV RNA. SatRPV RNA...

Presence of Recombinant Strain of Cucurbit Aphid Borne Yellows Virus in Iran

Background: Cucurbit aphid-borne yellows virus (CABYV) is among the most important yellowing viruses on cucurbits in Iran. The presence of CABYV has been previously reported from the major cucurbit growing areas in Iran, however, there are few studies concerning the detection of the diff erent strains of this virus in the grower’s fi elds, and especially, there is no report of ...

Cloning and expression of coat protein gene of the most prevailing citrus tristeza virus isolate in Northern Iran

Citrus tristeza is one of the most destructive diseases of citrus and its causing agent CTV was introduced from Japan to northern Iran in the late 1960s. After about three decades of restriction to originally infected Satsuma trees, natural spread of CTV has being undertaken and melon aphid (Aphis gossypii Glov.) was confirmed as a potent vector in these areas. Regarding the specificity of aphi...
