es, soybean mosaic potyvirus (SMV) pathosystem, seed-borne, maize chlorotic dwarf waikavirus (MCDV) pathosystem, comparing and contrasting the pathosystems, where biotechnology can clarify the process, phase 1: a non-viruliferous vector moves to and lands on a source plant, phase 2: the non-viruliferous vector acquires the virus from the source plant, phase 3: the vector processes the virus so that it can be transmitted to other plants, phase 4: the viruliferous vector carries the virus to a plant, phase 5 the viruliferous vector inoculates the plant, phase 6: the plant becomes infected and processes the virus so that it can be acquired by a vector, where biotechnology can help contain the epidemic, phase 1: a non-viruliferous vector moves to and lands on a source plant, phase 2: the vector acquires the virus from the source plant, phase 3: the vector processes the virus so that it can be transmitted to other plants, phase 4: the vector carries the virus to a non-infected pant, phase 5: the vector inoculates the plant, phase 6: the plant becomes infected and processes the virus so that it can be acquired by a vector.
