PI3K-Mediated Regulation of Glycogen Metabolism To Facilitate Virus Transmission by MED.

(ToCV), transmitted by whiteflies (), threatens global tomato production. However, the molecular mechanisms underlying the ToCV transmission by whiteflies remain largely unknown. Previous studies have shown that several key regulators of glycometabolism, downstream of the phosphoinositide 3-kinase (PI3K) pathway, are significantly increased in MED infected with ToCV.

Down-regulation of 14-3-3 genes suppress sugar metabolism in Bemisia tabaci MED and reduce transmission of tomato chlorosis virus.

Background: Tomato chlorosis virus (ToCV) is an RNA virus that seriously reduces tomato yield, mainly transmitted by whiteflies (Bemisia tabaci) in a semi-persistent manner. Currently, preventing ToCV transmission by selecting the target gene of whiteflies is an effective measure to control ToCV. Proteomic analysis revealed that 14-3-3 protein levels significantly increase in ToCV-infected B.

Neophytadiene, a Plant Specialized Metabolite, Mediates the Virus-Vector-Plant Tripartite Interactions.

While interactions between viruses and their vectors, as well as between viruses and host plants, have been extensively studied, the genetic mechanisms underlying tripartite interactions remain largely unknown. In this study, phenotypic assays are integrated with molecular biology and functional genomic approaches to elucidate the tripartite interactions involving tomato chlorosis virus (ToCV), a major threat to tomato production worldwide, the whitefly, Bemisia tabaci, an insect vector, and host plants. ToCV infection induces the production of a chlorophyll degradation product that acts as a volatile attractant for whiteflies.

Biological activity and field efficacy of Bacillus thuringiensis kurstaki strains with protein film adjuvants (PFAs) against Plutella xylostella (Lepidoptera: Plutellidae).

Background: Diamondback moth (DBM), Plutella xylostella L. is a globally distributed insect pest with developed resistance to many insecticides such as Cry1Ac proteins of Bacillus thuringiensis (Bt). It is therefore urgent to develop novel Bt bacterial strains with biocontrol activity against the DBM population.

Co-infection of TYLCV and ToCV increases cathepsin B and promotes ToCV transmission by MED.

Tomato disease is an important disease affecting agricultural production, and the combined infection of tomato chlorosis virus (ToCV) and tomato yellow leaf curl virus (TYLCV) has gradually expanded in recent years, but no effective control method has been developed to date. Both viruses are transmitted by Mediteranean (MED). Previously, we found that after MED was fed on ToCV-and TYLCV-infected plants, the transmission efficiency of ToCV was significantly higher than that on plants infected only with ToCV.

Effects of insulin-like peptide 7 in Bemisia tabaci MED on tomato chlorosis virus transmission.

Background: Tomato chlorosis virus (ToCV) is a semi-persistent plant virus that is primarily transmitted by the whitefly Bemisia tabaci (Hemiptera: Aleyrodidae). It causes a serious disease that lowers tomato yield. Insulin-like peptide (ILP), an insulin homolog, regulates trehalose metabolism in a variety of insects.

Repellence or attraction: secondary metabolites in pepper mediate attraction and defense against Spodoptera litura.

Background: Resistance to insect pests is an important self-defense characteristic of pepper plants. However, the resistance of different pepper cultivars to Spodoptera litura larvae, one of the main insect pest species on pepper, is not well understood.

Results: Among seven pepper cultivars evaluated, cayenne pepper 'FXBX' showed the highest repellency to third instar S.

Chinese Cabbage Changes Its Release of Volatiles to Defend against .

Plants respond to herbivorous insect attacks by releasing volatiles that directly harm the herbivore or that indirectly harm the herbivore by attracting its natural enemies. Although the larvae of (the tobacco cutworm) are known to induce the release of host plant volatiles, the effects of such volatiles on host location by and by the parasitoid , a natural enemy of larvae, are poorly understood. Here, we found that both the regurgitate of larvae and -infested cabbage leaves attracted .

Suppression of Bta11975, an α-glucosidase, by RNA interference reduces transmission of tomato chlorosis virus by Bemisia tabaci.

Background: Tomato chlorosis virus (ToCV) is mainly vectored by Bemisia tabaci in China, which has a worldwide distribution, and greatly reduces the yields of tomato and other vegetables. At present, control of ToCV has been focused mainly by the use of insecticides to control whitefly populations. Transcriptome sequencing showed high expression of the B.

Integrated Analysis of microRNA and mRNA Transcriptome Reveals the Molecular Mechanism of Response to and .

(ToCV), is one of the most devastating cultivated tomato viruses, seriously threatened the growth of crops worldwide. As the vector of ToCV, the whitefly Mediterranean (MED) is mainly responsible for the rapid spread of ToCV. The current understanding of tomato plant responses to this virus and is very limited.

Aphid endosymbiont facilitates virus transmission by modulating the volatile profile of host plants.

Background: Most plant viruses rely on vectors for their transmission and spread. One of the outstanding biological questions concerning the vector-pathogen-symbiont multi-trophic interactions is the potential involvement of vector symbionts in the virus transmission process. Here, we used a multi-factorial system containing a non-persistent plant virus, cucumber mosaic virus (CMV), its primary vector, green peach aphid, Myzus persicae, and the obligate endosymbiont, Buchnera aphidicola to explore this uncharted territory.

NSs, the Silencing Suppressor of Tomato Spotted Wilt Orthotospovirus, Interferes With JA-Regulated Host Terpenoids Expression to Attract .

Tomato spotted wilt orthotospovirus (TSWV) causes serious crop losses worldwide and is transmitted by (Pergande) (Thysanoptera: Thripidae). NSs protein is the silencing suppressor of TSWV and plays an important role in virus infection, cycling, and transmission process. In this research, we investigated the influences of NSs protein on the interaction of TSWV, plants, and with the transgenic .

Silencing of Odorant-Binding Protein Gene Using RNA Interference Reduced Virus Transmission of Tomato Chlorosis Virus.

Tomato chlorosis virus (ToCV) is widespread, seriously impacting tomato production throughout the world. ToCV is semi-persistently transmitted by (Gennadius) (Hemiptera: Aleyrodidae). Currently, insect olfaction is being studied to develop novel pest control technologies to effectively control and whitefly-borne virus diseases.

Toxicities and sublethal effects of seven neonicotinoid insecticides on survival, growth and reproduction of imidacloprid-resistant cotton aphid, Aphis gossypii.

Background: Imidacloprid has been a major neonicotinoid insecticide for controlling Aphis gossypii (Glover) (Homoptera: Aphididae) and other piercing-sucking pests. However, the resistance to imidacloprid has been recorded in many target insects. At the same time, cross-resistance of imidacloprid and other insecticides, especially neonicotinoid insecticides, has been detected.

Cross-reactivity of skin rashes with current antiepileptic drugs in Chinese population.

Objective: Due to less experience with the cross-reactivity of antiepileptic drugs (AEDs) in Chinese population, we surveyed the rates of cross- reactivity of rash among commonly used AEDs in Chinese patients with epilepsy, particularly between the traditional and the new compounds.

Methods: We have retrospectively reviewed the medical records concerning all antiepileptic drug treatment in consecutive Chinese patients with epilepsy in our center. The incidence of AED-related rash was determined in 3793 outpatients, taking at least one of the AEDs-carbamazepine (CBZ), valproic acid (VPA), phenytoin (PHT), phenobarbital (PB), clonazepam (CZP), oxcarbazepine (OXC), lamotrigine (LTG), gabapentin (GBP), topiramate (TPM), levetiracetam (LEV) and traditional Chinese medicine (TCM).
