Abstract ：
In this study, we report the discovery of a novel virus, Yunxiao leafhopper virus 1 (YXLeV1), found in the insect vector Recilia dorsalis, a significant pest of rice crop. The complete genome of YXLeV1, consisting of 14,115 bp, was sequenced and analyzed. The whole viral genome shares only 36.32% identity with the RNA-dependent RNA polymerase (RdRp) of Hubei diptera virus 11, belonging to genus Alasvirus. It contains four open reading frames encoding a nucleoprotein (N), a hypothetical protein (p78) of unknown function, a glycoprotein (G), and an RNA-dependent RdRp. The N, G, and RdRp proteins of YXLeV1 share 22.0%, 34.05%, and 36.32% amino acid sequence identity with the corresponding sequence of Hubei diptera virus 11. As per the genus demarcation criteria of the family Xinmoviridae, viruses sharing less than 60% amino acid identity in the RdRp sequence with known members are considered to belong to new genera, so the observed 36.32% identity between YXLeV1 and Hubei diptera virus 11 supports the classification of YXLeV1 as the first member of a novel genus, which we propose to name Recilivirus. Phylogenetic analysis further confirms that YXLeV1 is distantly related to Hubei diptera virus 11, the sole member of the genus Alasvirus, and forms a separate clade supporting its classification as a member of a new genus. Given the ecological significance of R. dorsalis as a vector, this discovery adds to the catalog of viruses associated with this species and contributes to our understanding of virus vector associations.

Abstract ：
Xenophagy is an important antibacterial defense mechanism that many organisms use to engulf intracellular pathogens. However, the mechanisms of xenophagy triggered by insect-borne plant bacteria are not well understood. Candidatus Liberibacter asiaticus (CLas) causes Huanglongbing, which poses a serious threat to citrus production. CLas is a phloem-limited unculturable bacterium that is transmitted by the Asian citrus psyllid in a persistent and propagative manner in nature. Here, we found that CLas infection in the gut of psyllids triggered a mild and anti-bacterial xenophagy. Xenophagy limited excessive propagation of CLas to maintain psyllid survival, because overload of CLas was detrimental to psyllid life. Furthermore, the outer membrane beta-barrel protein (OMBB) of CLas is the key secreted protein that induces xenophagy in psyllids by interacting with ATG8 and ATG14. OMBB can independently induce autophagy in psyllid and non-host cells. Together, these results revealed that an insect-borne plant bacterium activates mild xenophagy to control its propagation, thereby achieving persistent infection in insect vectors.

Abstract ：
In the field, 80% of plant viruses are transmitted by insect vectors. When ingested by a sap-sucking insect such as Recilia dorsalis, persistently transmitted viruses such as rice stripe mosaic virus (RSMV) infect the gut epithelium and eventually pass to the salivary glands where they will be transmitted to the next rice (Oryza sativa) plant. To efficiently exploit insect vectors for transmission, plant viruses must overcome various immune mechanisms within the vectors, including autophagy. However, understanding how plant viruses overcome insect autophagic defenses remains limited. In this study, we provide evidence that infection with RSMV triggers an autophagic antiviral response in leafhopper cells. In this response, the G protein of RSMV binds to a leafhopper AMP-activated protein kinase (AMPK), leading to enhanced phosphorylation of Beclin-1 (BECN1), thereby inducing autophagy. Knockdown of AMPK and genes encoding members of the phosphoinositide 3-kinase (PI3K) complex composed of the autophagy-related protein 14 (ATG14), BECN1, and vacuolar protein sorting 34 (VPS34) facilitated viral infection in leafhoppers. To suppress leafhopper-induced autophagy, RSMV M protein specifically interacts with ATG14, resulting in the disintegration of PI3K complexes. This leads to reduced phosphatidylinositol-3-phosphate content and thus inhibits the G-protein- induced autophagy. Our study sheds light on the mechanism by which this rice virus evades insect autophagy antiviral defenses.

Abstract ：
Janus kinase/signal transducer and activator of transcription (JAK/STAT) immune response traditionally requires cytokine binding to receptors for activation; however, it remains unclear whether cytokine receptors function as direct pattern recognition receptors (PRRs) that recognise viral envelopes. In this study, we demonstrate that cytokine receptor Domeless (Dome) in leafhopper Recilia dorsalis directly recognises glycoprotein (G) of an important rice rhabdovirus. This binding induces Dome dimerisation, which initiates JAK/STAT pathway and leads to STAT-dependent expression of antiviral immune effector in R. dorsalis (RdIE1). RdIE1 suppresses viral replication by inhibiting the RNA-binding activity of viral large polymerase (L). Dome residue T659 is essential for G recognition and L residues E774 and D775 are required for RdIE1 target. Notably, virus-encoded phosphoprotein competitively inhibits the phosphorylation of STAT by casein kinase II (CK2 beta), thereby abrogating STAT-dependent transactivation of target genes. Our findings redefine Dome as a viral sensor and reveal a biphasic strategy that balances antiviral immunity with persistent viral infection in insect vectors.

Abstract ：
Insect-borne pathogens often reduce the reproductive fitness of insect vectors. Rice gall dwarf virus (RGDV) is biparentally transmitted to the offspring of its leafhopper vector. However, maternal transmission of RGDV decreases female fecundity and disrupts egg development via an unknown mechanism. This study reveals that RGDV induces mitochondria-dependent apoptosis in leafhopper ovaries, promoting viral infection but impairing ovary development. This apoptosis is transmitted to eggs during maternal RGDV transmission, promoting viral infection while harming eggs. RGDV in the ovary activates insulin-like peptide-driven PI3K signaling but reverses the downstream AKT/FoxO signaling axis. This reversal activates FoxO, which in turn transcribes pro-apoptotic Bcl-2-related ovarian killer, triggering mitochondria-dependent apoptosis. Moreover, RGDV capsid protein P2 is the key viral protein responsible for inducing apoptosis through the PI3K/AKT/FoxO signaling axis. Specifically, P2 initiates mitochondria-dependent apoptosis by activating the PI3K signaling pathway upon recognition by insulin-like peptide 2. Furthermore, P2 reverses the AKT/FoxO signaling axis via its interaction with PTEN. In contrast, two rice viruses, which are exclusively maternally transmitted, do not induce apoptosis in the ovary of insect vectors. These findings uncover how this biparentally transmitted plant virus induces inheritable apoptosis, thereby imposing female reproductive costs, and highlight viral manipulation of vector reproduction to optimize transmission.
