Complete nucleotide sequence and genetic organization of papaya ringspot virus RNA.
The highly conserved sequence AAAUAAAANANCUCAACACAACAUA at the 5' end of the RNA of PRSV and those of the other five reported potyviruses shows 80% similarity, suggesting that this region may play a common important role for potyvirus replication.

It is concluded that the position of the heterologous sequences in the recombinants influences their pathogenicity on Rainbow, and the role of CP sequence similarity in overcoming the resistance of Rainbow is investigated.
Molecular characterization of the CP gene and 3'UTR of Chilli veinal mottle virus from South and Southeast Asia
A conserved region of 204 amino acids with more than 90·2% identity was identified in the C terminal of the CP gene of ChiVMV and Pepper veinal mottle virus, and may explain the serological cross reaction between these two viruses.

The inoculation of two purified PD bacteria to grape cultivars proved that the leaf scorch of grapevines in Taiwan is caused by the fastidious X. fastidiosa, the first report from the Asian Continent.
A single chimeric transgene derived from two distinct viruses confers multi-virus resistance in transgenic plants through homology-dependent gene silencing.

Results show that isolate TwPep3 should be considered as a new tospovirus and the name Pepper chlorotic spot virus (PCSV) is proposed, a specific primer pair designed in the N gene was successfully used in reverse transcription-polymerase chain reaction for PCSV diagnostic work.
MOLECULAR AND BIOLOGICAL CHARACTERIZATION OF AN ISOLATE OF APPLE STEM PITTING VIRUS CAUSING PEAR VEIN YELLOWS DISEASE IN TAIWAN

This is the first report of ASPV causing pear a disease in Taiwan and using 3'-CP conserved regions for nucleotide and amino acid sequence identity comparison among ASPV isolates provides better demarcating criteria for the taxonomy of ASPVs.
Tagging Rice Drought-related QTL with SSR DNA Markers

Applying SSR DNA markers that are closely linked with drought tolerance will facilitate early selection of drought tolerant lines and shorten breeding period.
A minimum length of N gene sequence in transgenic plants is required for RNA-mediated tospovirus resistance.

Evidence is provided that multiple virus resistance is possible through the simple strategy of linking viral gene segments to a silencer DNA such as GFP.
Xylella taiwanensis sp. nov., causing pear leaf scorch disease.
A Gram-stain-negative, nutritionally fastidious bacterium (PLS229T) causing pear leaf scorch was identified in Taiwan and previously grouped into Xylella fastidiosa. Yet, significant variations…
