“…Indeed, whereas our model supports coexistence of two acquisition modes-en bloc and sequential-the spatial separation in edIBs and elIBs of the viral players involved in transmission might result in sequential acquisition being predominant. Previous reports of an ''irregular biphasic'' transmission of CaMV by aphids (31)(32)(33) are compatible with this model. The first peak of transmission efficiency observed after short acquisition probes by aphids may correspond to the en bloc acquisition from elIBs (Fig.…”

Interactions between Cauliflower mosaic virus (CaMV) and its aphid vector are regulated by the viral protein P2, which binds to the aphid stylets, and protein P3, which bridges P2 and virions. By using baculovirus expression of P2 and P3, electron microscopy, surface plasmon resonance, affinity chromatography, and transmission assays, we demonstrate that P3 must be previously bound to virions in order that attachment to P2 will allow aphid transmission of CaMV. We also show that a P2:P3 complex exists in the absence of virions but is nonfunctional in transmission. Hence, unlike P2, P3 and virions cannot be sequentially acquired by the vector. Immunogold labeling revealed the predominance of spatially separated P2:P3 and P3:virion complexes in infected plant cells. This specific distribution indicates that the transmissible complex, P2:P3:virion, does not form primarily in infected plants but in aphids. A model, describing the regulating role of P3 in the formation of the transmissible CaMV complex in planta and during acquisition by aphids, is presented, and its consequences are discussed.

“…3e). Chalfant & Chapman (1962) and Lim & Hagedorn (1977) also found the two peaks which they interpreted as being a bimodal curve representing both non-persistent and (semi-) persistent acquisition phases. It might be more realistic to interpret these curves as being biphasic (two stages of the semi-persistent acquisition phase) with the first peak at about 15 to 60 min, depending on species, and the true bimodal system, if one exists, as being shown by M .…”

“…acquired CaMV over periods from a few seconds to 24 h, with no enhancement following starvation. But Chalfant & Chapman (1962) reported that B . brassicae exhibited an unusual bimodal transmission pattern that demonstrated features of both non-persistent and persistent transmission, although in the modern terminology, their 'persistent' would more accurately be described as semi-persistent.…”

S U M M A R YThe acquisition and transmission of cauliflower mosaic virus (CaMV) by six aphid species and three clones of aphids was studied and compared with that of turnip mosaic virus (TuMV) with Myzuspersicae. Two clones of Aphisfabae were unable to transmit CaMV, but the other species, Acyrthosiphon pisum, Brevicoryne brassicae, Megoura viciae. M . persicae and Rhopalosiphum padi transmitted in a bior multi-phasic manner. There was no statistical evidence of a bimodal transmission pattern. R . padi is recorded as a vector of CaMV for the first time.The transmission efficiency of CaMV varied with time of acquisition and suggested that accumulation of the virus occurred with two peaks of efficiency within the anterior region of the insect gut. The time at which these two peaks occurred varied between the species, but the basic pattern was common to all transmitting aphid species in this study. This pattern contrasted with that of TuMV. The transmission data are discussed in terms of bimodal transmission, the influence of feeding behaviour, the role of a helper protein associated with both TuMV and CaMV and the evidence for site specific attachment of CaMV.

Coated pits bud off the APL as virus-containing coated vesicles (CV), which transport the virus (3) to larger uncoated vesicles, called receptosomes (RS), which act to concentrate the virus (4).…”
