First report of carrot torrado virus 1 (CaTV1) naturally infecting carrots in Spain
Bisola Mercy Babalola, Chantal Faure, Armelle Marais, Aurora Fraile, Fernando Garcia‑Arenal, Thierry Candresse. https://doi.org/10.1007/s42161-022-01196-x Carrot torradovirus 1 (CaTV1) has been reported in carrot in the UK, France and Japan and in other Apiaceae in Germany and Greece. In June 2021, Illumina sequencing of five cultivated carrot populations from Segovia (Spain) revealed the presence of CaTV1 in four of them. Genomic contigs showed respectively 95% (RNA1) and 98% (RNA2) nucleotide identity with those of the reference isolate (KF533719-20). CaTV1 presence was confirmed using a two-step RT-PCR assay. To our knowledge, this is the first report of CaTV1 infection in carrots in Spain.

Carrot torradovirus 1 (CaTV1) has been reported in carrot in the UK, France and Japan and in other Apiaceae in Germany and Greece. In June 2021, Illumina sequencing of five cultivated carrot populations from Segovia (Spain) revealed the presence of CaTV1 in four of them. Genomic contigs showed respectively 95% (RNA1) and 98% (RNA2) nucleotide identity with those of the reference isolate (KF533719-20). CaTV1 presence was confirmed using a two-step RT-PCR assay. To our knowledge, this is the first report of CaTV1 infection in carrots in Spain. The sequencing reads also revealed other carrot-infecting viruses so that it is not possible to derive conclusions on the pathogenicity of CaTV1, for which efforts are still needed.
