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.

Metagenomic analysis of the dynamical conversion of photosynthetic bacterial communities in different crop fields over different growth periods.

Photosynthetic bacteria are beneficial to plants, but knowledge of photosynthetic bacterial community dynamics in field crops during different growth stages is scarce. The factors controlling the changes in the photosynthetic bacterial community during plant growth require further investigation. In this study, 35 microbial community samples were collected from the seedling, flowering, and mature stages of tomato, cucumber, and soybean plants.

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 .

The NIa-Protease Protein Encoded by the Is a Pathogenicity Determinant and Releases DNA Methylation of .

It is well documented that the canonical function of NIa-protease (NIa-Pro) of the potyviruses is responsible for cleaving the viral polyprotein into functional proteins. Although NIa-Pro is vital for the infection cycle of potyviruses, the function of NIa-Pro in the interaction of the potyvirus host is not clear. In this study, NIa-Pro is ectopically expressed from a (PVX) vector and infiltrates wild type and 16-TGS.

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.

[Evaluation of Down's syndrome screening methods using maternal serum biochemistry in the second trimester pregnancy].

Objective: To provide basis for selecting the suitable method of Down's syndrome biochemical screening in the second trimester pregnancy.

Methods: A total of 30 547 singleton pregnancies between 14 and 20(+ 6) weeks of pregnancy were collected and analyzed for maternal serum alpha-fetoproteins (AFP) and human chorionic gonadotrophin, free beta subunit (beta-HCG) with or without unconjugated estriol (uE3). The screening risks were calculated using the software Lifecycle.

[Cloning and prokaryotic expression of Rhodoblastus acidophilus 5-aminolevlinate synthase gene].

5-aminolevulinic acid (ALA) is formed by the enzyme ALA synthase (ALAS). However, the fidelity of ALAS gene among species is low. The ALAS gene of photosynthetic bacteria Rhodoblastus acidophilus was cloned from its genomic DNA by conventional PCR and Veterette PCR and further sequenced.
