“…The interactions among host plants, plant viruses, and insect vectors are multiple and complex [ 3 , 27 , 28 ]. Plant virus infection could alter chemical cues and behavioral changes in its host plants and insect vectors that enhance virus epidemic and dispersal [ 4 , 10 , 29 , 30 ].…”

“…Plant viruses are most often transmitted by insect vectors including thrips, whiteflies, planthoppers, leafhoppers, and aphids [ 1 ], and they seriously threaten crop yield and lead to major economic losses [ 2 ]. Insect vectors, plant viruses, and host plants form complex multilevel interactions that affect virus dispersal [ 3 ]. For persistent plant viruses transmitted by insect vectors, studies have found that non-viruliferous insect vectors initially preferred virus-infected plants, but once the virus was acquired by the vectors, they showed a predilection for virus-free plants, and this phenomenon may accelerate the outbreak of virus [ 4 ].…”

“…However, upon RBSDV infection, the induction of OsGSK2 positively regulates the JA antiviral response to RBSDV by promoting the phosphorylation and degradation of OsJAZ4, a repressor of the JA signaling [ 105 ]. During the early stage of SRBSDV infection, SRBSDV P6 activates ethylene signaling via interacting with OsRTH2 in the cytoplasm, thus leading to enhanced SRBSDV proliferation [ 106 ]. These findings imply positive roles of JA and auxin for antiviral defense, but ethylene contributes to virus proliferation.…”

“…Emerging evidence has proven that rice viruses can manipulate their vectors either directly or by inducing changes in host plants to promote the spread of viral pathogens. For example, during the late infection of SRBSDV in rice plants, SRBSDV P6 enters the nucleus and interacts with OsEIL2 to suppress ethylene signaling by blocking the dimerization of OsEIL2, thus promoting virus spread via attracting the insect vector [ 106 ]. It implies more complex interactions among insect vectors, viruses, and host plants contribute the transmission of viruses by balancing all organizational levels, from molecules to populations.…”

“…For instance, the potyviral protein NIa-Pro from turnip mosaic virus (TuMV) resides in the nucleus primarily during infection, but it relocalizes outside of the nucleus to enhance aphid vector fecundity, and inhibits aphid induction of ethylene-dependent defences when expressed in plants [6][7][8]. The viral protein P6 of southern rice black-streaked dwarf virus (SRBSDV) interacts with the rice host transcription factor OsEIL2 and increases vector planthopper attraction to plants expressing P6 [9]. Many other viral proteins also have a similar function, such as the 2b protein from cucumber mosaic virus (CMV), which prevents the degradation of JAZ proteins and the induction of downstream volatiles, increasing aphid vector attraction to infected plants [10,11].…”
