"The ornamental species, ornamental plum (P. cerasifera) and ornamental (Japanese) quince (C. japonica) showed high ACLSV prevalence (28/38 and 24/62, respectively). In rose (R. canina) and C. monogyna the virus was less frequent (2/26 and 1/40, respectively) while ACLSV was not detected in P. coccinea (firethorn; 0/29)."

"ACLSV was also detected in wild Rosaceae species such as Rubus sp. (1/2), wild cherry (Cerasus nigra, 6/ 36), Prunus spinosa (5/14), P. pindicola (1/7), P. amygdaliformis (10/81), wild rose (R. acicularis, 1/9) and wild pear (P. pyraster, 1/43)."

"ACLSV was also detected both by ELISA and RT-PCR assays in rose (R. canina), Rubus sp. and P. pindicola and therefore these species may represent newly recorded natural hosts (Table 3)."

"ACLSV was also detected in rose (R. canina) and the wild species Rubus sp. and P. pindicola, which could represent previously unidentified natural hosts. Nevertheless, because no sequence data could be obtained from the amplicons, further research is needed to support these findings."

Concerning spread:
"Even though vegetative propagation and grafting could explain virus spread and maintenance in the cultivated and ornamental plants, they cannot account for its presence in the wild species. In these hosts ACLSV could either be transmitted by seed, pollen or by a putative vector even if it has not been reported to be spread in this way (Yoshikawa, 2001)."
