Defense strategies against sweet potato chlorotic stunt and pakakuy virus coinfection unraveled

Crop Science, Volume 64, Issue 6, Page 3438-3460, November/December 2024.
Abstract This study into the response of two Ipomoea batatas (L.) Lam cultivars, Melinda and Tio Joe, to coinfection with sweet potato chlorotic stunt virus (SPCSV) and sweet potato pakakuy virus (SPPV), employed a comprehensive approach encompassing symptomatology, real‐time quantitative polymerase chain reaction, metagenomics, and transcriptomics ...

Aminoglycoside-4'-nucleotidyltransferase from Bacillus brevis.

Agricultural and Biological Chemistry, 1980
The existence of aminoglycoside-4′-nucleotidyltransferase [AAD(4′)] was demonstrated in the cell-free extract of B. brevis. This enzyme was purified about 100-fold over the cell-free extract by column chromatography using DEAE-cellulose and affinity chromatography using butirosin A-Sepharose 4B.AAD(4′) of B. brevis catalyzed the transfer of nucleotides

Agrobacterium VirD2-Binding Protein Is Involved in Tumorigenesis and Redundantly Encoded in Conjugative Transfer Gene Clusters

Molecular Plant-Microbe Interactions, 2007
Agrobacterium tumefaciens can transfer oncogenic T-DNA into plant cells; T-DNA transfer is mechanistically similar to a conjugation process. VirD2 is the pilot protein that guides the transfer, because it is covalently associated with single-stranded T ...

A Non-Dicer RNase III and Four Other Novel Factors Required for RNAi-Mediated Transposon Suppression in the Human Pathogenic Yeast Cryptococcus neoformans

G3: Genes, Genomes, Genetics, 2019
The human pathogenic yeast Cryptococcus neoformans silences transposable elements using endo-siRNAs and an Argonaute, Ago1. Endo-siRNAs production requires the RNA-dependent RNA polymerase, Rdp1, and two partially redundant Dicer enzymes, Dcr1 and Dcr2 ...

Isolation of a temperature-sensitive mutant with an altered tRNA nucleotidyltransferase and cloning of the gene encoding tRNA nucleotidyltransferase in the yeast Saccharomyces cerevisiae.

Journal of Biological Chemistry, 1990
We have isolated a yeast mutant, ts352, that is temperature-sensitive for growth. The mutation has a general effect on mRNA metabolism and a specific effect on tRNA biosynthesis. Cells shifted to the nonpermissive temperature accumulate tRNAs that are shorter than mature tRNAs. The increased ability of these tRNAs to accept ATP demonstrates that growth

Characterization of Escherichia coli strains isolated from geese by detection of integron-mediated antimicrobial resistance

Journal of Global Antimicrobial Resistance, 2022
: Objectives: Current research shows that the resistance of Escherichia coli (E. coli) is mainly related to integron gene cassettes. To assess the resistance of E. coli of goose origin and the carriage of its integron genes in four farms in Heilongjiang

Function and Regulation of Human Terminal Uridylyltransferases

Frontiers in Genetics, 2018
RNA uridylylation plays a pivotal role in the biogenesis and metabolism of functional RNAs, and regulates cellular gene expression. RNA uridylylation is catalyzed by a subset of proteins from the non-canonical terminal nucleotidyltransferase family.
