Genome-Wide Identification and Characterization of the Gene Family in Bread Wheat ( L.).

Cystatins, as reversible inhibitors of papain-like and legumain proteases, have been identified in several plant species. Although the family plays crucial roles in plant development and defense responses to various stresses, this family in wheat ( L.) is still poorly understood.

Binding between elongation factor 1A and the 3'-UTR of Chinese wheat mosaic virus is crucial for virus infection.

The Chinese wheat mosaic virus (CWMV) genome consists of two positive-strand RNAs that are required for CWMV replication and translation. The eukaryotic translation elongation factor (eEF1A) is crucial for the elongation of protein translation in eukaryotes. Here, we show that silencing eEF1A expression in Nicotiana benthamiana plants by performing virus-induced gene silencing can greatly reduce the accumulation of CWMV genomic RNAs, whereas overexpression of eEF1A in plants increases the accumulation of CWMV genomic RNAs.

Genome-wide identification and characterization of UBP gene family in wheat ( L.).

Ubiquitination is essential for plant growth and development. Deubiquitination cooperates with ubiquitination to regulate the ubiquitination levels of target proteins. The ubiquitin-specific protease (UBP) family is the largest group of deubiquitinases (DUBs), which perform extensive and significant roles in eukaryotic organisms.

Transcriptome-Wide N-Methyladenosine (mA) Profiling of Susceptible and Resistant Wheat Varieties Reveals the Involvement of Variety-Specific mA Modification Involved in Virus-Host Interaction Pathways.

N-methyladenosine (mA) methylation is the most prevalent internal modification of post-transcriptional modifications in mRNA, tRNA, miRNA, and long non-coding RNA in eukaryotes. mA methylation has been proven to be involved in plant resistance to pathogens. However, there are no reports on wheat () mA transcriptome-wide map and its potential biological function in wheat resistance to wheat yellow mosaic virus (WYMV).

A virus-derived siRNA activates plant immunity by interfering with ROS scavenging.

Virus-derived small interference RNAs (vsiRNAs) not only suppress virus infection in plants via induction of RNA silencing but also enhance virus infection by regulating host defensive gene expression. However, the underlying mechanisms that control vsiRNA-mediated host immunity or susceptibility remain largely unknown. In this study, we generated several transgenic wheat lines using four artificial microRNA expression vectors carrying vsiRNAs from Wheat yellow mosaic virus (WYMV) RNA1.

NbWRKY40 Positively Regulates the Response of to Tomato Mosaic Virus via Salicylic Acid Signaling.

WRKY transcription factors play important roles in plants, including responses to stress; however, our understanding of the function of genes in plant responses to viral infection remains limited. In this study, we investigate the role of in resistance to tomato mosaic virus (ToMV). is significantly downregulated by ToMV infection, and subcellular localization analysis indicates that NbWRKY40 is targeted to the nucleus.

Genome-wide identification of the histone acetyltransferase gene family in Triticum aestivum.

Background: Histone acetylation is a ubiquitous and reversible post-translational modification in eukaryotes and prokaryotes that is co-regulated by histone acetyltransferase (HAT) and histone deacetylase (HDAC). HAT activity is important for the modification of chromatin structure in eukaryotic cells, affecting gene transcription and thereby playing a crucial regulatory role in plant development. Comprehensive analyses of HAT genes have been performed in Arabidopsis thaliana, Oryza sativa, barley, grapes, tomato, litchi and Zea mays, but comparable identification and analyses have not been conducted in wheat (Triticum aestivum).

Wheat Yellow Mosaic Virus NIb Interacting with Host Light Induced Protein (LIP) Facilitates Its Infection through Perturbing the Abscisic Acid Pathway in Wheat.

Positive-sense RNA viruses have a small genome with very limited coding capacity and are highly reliant on host factors to fulfill their infection. However, few host factors have been identified to participate in wheat yellow mosaic virus (WYMV) infection. Here, we demonstrate that wheat ( ) light-induced protein (LIP) interacts with the WYMV nuclear inclusion b protein (NIb).
