Identification and Characterization of Four Novel Viruses in .

(Cicadellidae: Deltocephalinae), a leafhopper prevalent in tropical and temperate regions, is notably abundant in grasses and rice. The virome of was investigated using deep transcriptome sequencing, leading to the first identification of four viruses belonging to the families , , and in . These viruses have been provisionally named B.

Discovery and Genomic Analysis of Three Novel Viruses in the Order in Leafhoppers.

Leafhoppers are economically important pests and may serve as vectors for pathogenic viruses that cause substantial crop damage. In this study, using deep transcriptome sequencing, we identified three novel viruses within the order , including two viruses belonging to the family and one to the family . The complete genome sequences were obtained via the rapid amplification of cDNA ends and tentatively named Recilia dorsalis rhabdovirus 1 (RdRV1, 14,251 nucleotides, nt), Nephotettix virescens rhabdovirus 1 (NvRV1, 13,726 nt), and Nephotettix virescens lispivirus 1 (NvLV1, 14,055 nt).

Screening and Characterization of a New Iflavirus Virus in the Fruit Tree Pest .

is one of the common pests of fruit trees, but the research on the pathogenic microorganisms it may carry is very limited. Therefore, it is essential to reveal the pathogenic microbes it carries and their potential hazards. This study found a new virus from the transcriptome of , which was first reported in and named PyCaV ( associated virus).

Comparative Analysis of Transposable Elements in Strawberry Genomes of Different Ploidy Levels.

Transposable elements (TEs) make up a large portion of plant genomes and play a vital role in genome structure, function, and evolution. Cultivated strawberry () is one of the most important fruit crops, and its octoploid genome was formed through several rounds of genome duplications from diploid ancestors. Here, we built a pan-genome TE library for the genus using ten published strawberry genomes at different ploidy levels, including seven diploids, one tetraploid, and two octoploids, and performed comparative analysis of TE content in these genomes.

Full genome sequence of a novel iflavirus from the aster leafhopper Macrosteles fascifrons.

The aster leafhopper Macrosteles fascifrons is a common insect pest that feeds on rice and other plants and may serve as a vector to transmit various viruses. Here, we discovered a novel virus from M. fascifrons using metagenomic sequencing.

ROP signaling regulates spatial pattern of cell division and specification of meristem notch.

The formation of cell polarity is essential for many developmental processes such as polar cell growth and spatial patterning of cell division. A plant-specific ROP (h-like GTPases from lants) subfamily of conserved Rho GTPase plays a crucial role in the regulation of cell polarity. However, the functional study of ROPs in angiosperm is challenging because of their functional redundancy.

Full genome sequence of a novel iflavirus from the leafhopper Recilia dorsalis.

The leafhopper Recilia dorsalis (family Cicadellidae, tribe Deltocephalini) is a common pest of rice and a transmitter of various viruses. Here, we discovered a novel virus in an R. dorsalis sample and determined its complete genome sequence by metagenomic sequencing and rapid amplification of cDNA ends.

Roles of CsBRC1-like in leaf and lateral branch development in cucumber.

TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP) family genes, as plant-specific transcription factors, play vital roles in flower pattern, leaf development and plant architecture. Our recent study shows that the TCP gene BRANCHED1 (CsBRC1) specifically regulates shoot branching in cucumber. Here, we found CsBRC1 had a closely related paralogous gene CsBRC1-like.

Metabolite signatures of diverse Camellia sinensis tea populations.

The tea plant (Camellia sinensis) presents an excellent system to study evolution and diversification of the numerous classes, types and variable contents of specialized metabolites. Here, we investigate the relationship among C. sinensis phylogenetic groups and specialized metabolites using transcriptomic and metabolomic data on the fresh leaves collected from 136 representative tea accessions in China.

Pharmacokinetics and liver uptake of three Schisandra lignans in rats after oral administration of liposome encapsulating β-cyclodextrin inclusion compound of Schisandra extract.

Schisandra chinensis fructus (SCF) is widely used traditional Chinese medicine, which possesses hepato-protective potential. Schisandrin (SD), schisantherin (ST), and γ-schizandrin (SZ) are the major bioactive lignans. The main problem associated with the major bioactive lignans oral administration is low oral bioavailability due to the lignans' poor aqueous solubility and taste.

Inference of a Geminivirus-Host Protein-Protein Interaction Network through Affinity Purification and Mass Spectrometry Analysis.

Viruses reshape the intracellular environment of their hosts, largely through protein-protein interactions, to co-opt processes necessary for viral infection and interference with antiviral defences. Due to genome size constraints and the concomitant limited coding capacity of viruses, viral proteins are generally multifunctional and have evolved to target diverse host proteins. Inference of the virus-host interaction network can be instrumental for understanding how viruses manipulate the host machinery and how re-wiring of specific pathways can contribute to disease.

Identification of the ASR gene family from Brachypodium distachyon and functional characterization of BdASR1 in response to drought stress.

A genome-wide investigation identified five B. distachyon ASR genes. BdASR1 may be a transcription factor that confers drought resistance by activating antioxidant systems involving ROS-scavenging enzymes and non-enzymatic antioxidants.
