Unusual symptoms including yellowing, stunting, curling, crumpling and plant size reduction were observed in tomato fields and green houses in Tunisia. These symptoms, generally associated with the Tomato yellow leaf curl virus (TYLCV) complex, have

Viroids of fruit trees are plant pathogens distributed worldwide and can cause severe losses and economic damage to crops. A survey of fruit trees was carried out in 17 orchards in the northern and Sahel regions of Tunisia. Samples were collected in

Almond (Prunus dulcis Mill) is an important crop in countries of the Mediterranean area. Until now, among viroids, only Hop stunt viroid (HSVd) is known to infect cultivated almond trees (2). In 2004, a survey of almond trees was carried out in orcha

The presence of Peach latent mosaic viroid (PLMVd) was monitored during 2 years in peach orchards located in the North of Tunisia. PLMVd population was surveyed using a specific RT-PCR test adapted to crude sap extract. During the first year (2004),

Nucleotide sequences of a broad range of Peach Latent Mosaic Viroid (PLMVd) variants were determined. The variants were isolated from peach, pear, and almond tree samples collected in Tunisia. Sequence analysis confirmed the high variability of PLMVd

The peach latent mosaic viroid (PLMVd) is a small, circular RNA species that has been shown to induce RNA silencing in plants. With the goal of better understanding the biological mechanism underlying this process, the siRNAs found in PLMVd infected

Peach latent mosaic viroid (PLMVd) is a single-stranded circular RNA that do not code for proteins and ranges in size from 335 to 351 nucleotides. It mainly infects peach. In this study, the sequence of 20 complete cDNA clones derived from seven PLMV

A rapid and sensitive assay was developed for the detection and identification of Peach latent mosaic viroid (PLMVd) by reverse transcription-polymerase chain reaction (RT-PCR) in infected tissues from Tunisian orchards. The test was initially perfor
