Chili is one of the important commodities in Indonesia. cultivation faces many obstacles, leading to a decrease production, such as virus infections. Yellow leaf curl and curly top viruses are groups that often found chili fields. This research was conducted investigate effect intercropping (basil-chili) suppressing viral diseases, especially yellow viruses. A Randomized block design used for t...

The mutation frequency of Turnip crinkle virus can increase 12-fold without inducing error catastrophe. Lesions in a hairpin repressor frequently reverted and led to second-site alterations biased for specific mutations. These results suggest that the hairpin may also function as an RNA chaperone to properly fold the RNA-dependent RNA polymerase.

In exploring the role of the chloroplast in the multiplication of turnip yellow mosaic virus, the biosyntheses of the major viral polyamine, spermidine, as well as that of the tetramine, spermine were studied. The synthesis of these polyamines from [2-(14)C]methionine in protoplasts of Chinese cabbage leaf cells derived from healthy plants or those infected by turnip yellow mosaic virus were ex...

Title of dissertation: THE 3’ UTR OF TURNIP CRINKLE VIRUS INTERACTS LOCALLY AND DISTALLY TO REGULATE TRANSCRIPTION AND TRANSLATION OF THE VIRUS Megan Y. L. Young, Doctor of Philosophy, 2012 Dissertation Directed by: Professor Anne E. Simon Department of Cell Biology and Molecular Genetics Turnip crinkle virus (TCV) is a 4054 b positive-strand RNA virus of the genus Carmovirus in the Family Tomb...

Tobacco mosaic virus and turnip yellow mosaic virus genome RNAs, which have long (greater than or equal to 69 nucleotides) 5'-terminal leader sequences preceding the AUG initiation codon, can form disome initiation complexes when incubated with a wheat germ extract and sparsomycin. In tobacco mosaic virus RNA, whereas one ribosome in such complexes presumably occupies the AUG-containing initiat...

The 5' UTR of turnip yellow mosaic virus RNA contains two conserved hairpins with internal loops consisting of C.C and C.A mismatches. In this article, evidence is presented indicating that the 5' proximal hairpin functions as an encapsidation initiation signal. Extensive mutagenesis studies on this hairpin and sequencing of virus progeny showed a clear preference for C.C and C.A mismatches wit...
