Summary: Plants produce chemical defenses to poison or deter insect herbivores, but these defenses may also affect the beneficial endosymbionts of the herbivores. This study found that rice produces an antifungal flavonoid phytoalexin in response to attack by a pest, which inhibits the pest's beneficial endosymbionts.

Summary: This study reveals the importance of transferrin genes NlTsf1, NlTsf2, and NlTsf3 in the interaction between rice and brown planthopper (BPH). RNAi treatment of NlTsf3 significantly reduces the egg production of BPH, while treatments of NlTsf1 and NlTsf2 also affect the survival rate of BPH.

Summary: The transcription factor OsSPL10 was found to play a negative role in rice defense against the brown planthopper (BPH). Knockout of the OsSPL10 gene enhanced rice resistance against BPH by upregulating defense-related genes and accumulating secondary metabolites. The findings suggest that OsSPL10 can be a potential target for genetic improvement of BPH resistance in rice.

Summary: The study investigated the effects of nymph feeding of the small brown planthopper (SBPH) on rice metabolites. It was found that SBPH nymph feeding increased the susceptibility of rice plants to SBPH infestation. SBPH feeding significantly altered 92 metabolites, including defense-related secondary metabolites. Flavonoid biosynthesis in rice was suppressed by SBPH nymph feeding, leading to increased susceptibility to SBPH infestation.

Summary: This study conducted a transcriptomic and metabolomic analysis to investigate the response of Bph30 gene to BPH infestation. The results revealed that Bph30 enhances the resistance of rice to BPH by coordinating the movement of endogenous hormones and metabolites. These findings have important reference significance for understanding the resistance mechanisms and efficient utilization of major BPH-resistance genes.

Summary: The rice sesquiterpene synthase II gene plays a role in the antixenosis defense mechanism against brown planthopper infestation, with differences in functionality observed between resistant and susceptible rice varieties. Single-nucleotide polymorphisms in the gene's promoter region and exon 5, as well as a seven amino acid deletion in the protein sequence, may negatively regulate gene function. Analysis suggests a correlation between SNPs in specific genes and the expression of OsSTPS2, while a 21 bp deletion in exon 5 affects the antixenosis mechanism during BPH infestation.

Summary: This study reveals the involvement of miRNA in plant defense response against brown planthopper (BPH). The genetic history of rice varieties determines the regulation mode of miRNA and affects their response to BPH-feeding. Furthermore, a potential cross-kingdom miRNA, miR5795, is found to target a gene in BPH, leading to a reduction in BPH oviposition.

Summary: The study revealed that the simple eLRR protein OsI-BAK1 in rice plays a crucial role in defense against the brown planthopper (BPH), acting as a negative regulator of defense-related genes and influencing BPH parasitism and oviposition. The findings suggest that BPH may exploit OsI-BAK1 as a modulator for its own benefit.

Summary: This study demonstrates that the use of decoyinine as a seed treatment significantly reduces the fecundity of the small brown planthopper (SBPH) and improves rice resistance. Decoyinine enhances rice defense against SBPH by stimulating plant defensive responses, making it a potential environmentally friendly alternative to chemical pest control.

Summary: Plants have a defense system against insect pests, and cytokinin plays a crucial role in enhancing rice resistance against the brown planthopper. The presence of cytokinin promotes the biosynthesis and signaling in response to brown planthopper feeding. This resistance is dependent on the plant hormone jasmonic acid.

Summary: The study demonstrates that inhibition of hepatocyte nuclear factor 4 confers imidacloprid resistance in brown planthopper by regulating cytochrome P450 and UDP-glycosyltransferase genes. Knockdown of HNF4 enhances resistance to imidacloprid in BPH, leading to up-regulation of cytochrome P450- and UGT-mediated metabolic detoxification pathways. Over-expression of UGT-1-7, UGT-2B10, and CYP6ER1 in the resistant strain indicates potential targets for pest management.

Summary: Plants release herbivore-induced plant volatiles (HIPVs) to communicate with other organisms in the environment. Insect herbivores can use these odors to upregulate detoxification systems, such as cytochrome P450 monooxygenases (P450s), for tolerance to insecticides. Olfactory exposure to HIPVs enhances larval insecticide tolerance via induction of detoxification P450s.

Summary: Clonal plants form interconnected networks that allow for the sharing and redistribution of resources. These networks can also induce systemic resistance against herbivores. In rice plants, defense communication occurs between the main stem and clonal tillers, mediated by the JA signaling pathway. This discovery provides a theoretical basis for utilizing the systemic resistance of clonal plants for ecological pest control.

Summary: Polyamines play an important role in the interaction between rice and striped stem borer (SSB). SSB larval infestation leads to an accumulation of polyamines in rice plants, which benefits the growth of SSB. The defense responses in rice are regulated by the addition of polyamines or the inhibition of polyamine biosynthesis.

Summary: Kiwifruit cultivars are prone to damage under waterlogging stress, but a wild germplasm called Maorenshen (A. valvata Dunn, MRS) exhibits higher tolerance to waterlogging stress. MRS plants showed better physiological characteristics, such as higher photosynthetic rates and root activity, compared to a cultivar called Miliang-1 (A. chinensis var. deliciosa (A.Chev.) A.Chev. cv. Miliang-1, ML), under stress conditions. The waterlogging tolerance of MRS was associated with higher activities of pyruvate decarboxylase (PDC) and alcohol dehydrogenase (ADH), as well as increased antioxidant ability.
