Fusion of adjacent surface membranes does not necessarily fellow aggregation, and has not been observed in protoplasts aggregated by antisera. The other three methods all result in some degree of fusion, depending upon the state of the protoplasts and the temperature of the experiment. Fusion is favoured by a high density of cytoplasm in the ...

Disease outbreaks in plant-vector-virus models with vector ...

While feeding on host plants, viruliferous insects serve as vectors for viruses. Successful viral transmission depends on vector behavior. Two behaviors that impact viral transmission are vector aggregation and dispersal. Vector aggregation may be due to chemical or visual cues or feeding preferences. Vector dispersal can result in widespread disease outbreaks among susceptible host plants.

Sequence-Specific Protein Aggregation ... - Plant Physiology

Protein aggregation is determined by short (5–15 amino acids) aggregation-prone regions (APRs) of the polypeptide sequence that self-associate in a specific manner to form β-structured inclusions. Here, we demonstrate that the sequence specificity of APRs can be exploited to selectively knock down proteins with different localization and function in plants.

The role of aggregation in the context of a specific virus is often poorly understood, especially in the case of plant viruses. The aggregates are utilized by viruses to house a large complex of proteins of both viral and host origin to promote virus replication, translation, intra- and intercellular transportation.
