Loquat (Eriobotrya japonica) is an important crop in Spain. To date, only one viral species, apple stem pitting virus (ASPV), has been detected in Spanish loquat orchards. In this study, the presence of additional viruses infecting this crop in Spain was investigated. RT-PCR and high-throughput sequencing (HTS) of symptomatic loquat plants led to first-time detection and characterization of apple stem grooving virus (ASGV), also known as citrus tatter leaf virus (CTLV), and apple chlorotic leaf spot virus (ACLSV) from Spain with description of nearly complete genomic sequences. The frequency of ACLSV infection was the highest, with over 30% of the samples testing positive and were also detected as coinfections with ASGV and ASPV, although most of the samples infected were symptomless. Studies on all the full-length sequences available in the databases were performed in order to establish the phylogenetic relationships of the Spanish isolates of these two viral species. Moreover, apple hammerhead viroid (AHVd) was also detected to infect loquat, the first host different from apple reported for this viroid to date.

Citrus Tatter Leaf Virus

A magnetic bead-based immunocapture system using polyclonal antiserum against Apple stem grooving virus (ASGV) successfully facilitated polymerase chain reaction (PCR) amplification of sequences from three Citrus tatter leaf virus (CTLV) isolates originally isolated from the citrus host Meyer lemon. Primers designed from a pairwise alignment of genomic sequences of CTLV isolates from lily and from kumquat amplified two nonoverlapping genomic regions of 625 and 1,165 bp (approximately 28% of the CTLV genome) which were cloned and sequenced. Despite being propagated separately in the glasshouse for more than 40 years, the CTLV sequences from separate Meyer lemon sources were identical but had only approximately 80% nucleotide identity with the homologous regions of CTLV genomes of isolates from lily and kumquat. Neighbor-joining phylogenetic analysis indicated the CTLV isolates from Meyer lemon were distinct from but more closely related to CTLV from kumquat than from lily, and these CTLV sequences showed equivalent genetic distances from two ASGV isolates.

Surveys to determine the phytosanitary status of apple (Malus) and pear (Pyrus) trees in New Zealand were conducted from 2005 to 2006 A total of 188 symptomatic and nonsymptomatic trees from various geographical locations were tested for the presence of a number of viruses and viroids by RTPCR All Malus samples were tested for Apple chlorotic leaf spot virus (ACLSV) Apple stem grooving virus (ASGV) Apple stem pitting virus (ASPV) Apple mosaic virus (ApMV) Apple scar skin viroid (ASSVd) Apple dimple fruit viroid (ADFVd) Cherry rasp leaf virus (CRLV) and Tomato ringspot virus (ToRSV) ACLSV was detected in 48 ASGV in 36 ASPV in 61 and ApMV in 45 of samples tested ASSVd ADFVd CRLV ToRSV were not detected in any of the 165 sampled Malus plants which provides evidence that they are not present in New Zealand All Pyrus samples were tested for ACLSV ASGV ASPV ApMV Pear latent virus (PeLV) and Pear blister canker viroid (PBCVd) ACLSV was detected in 17 ASGV in 13 ASPV in 17 and ApMV in 4 of sampled Pyrus trees PeLV and PBCVd were not detected in any of the 23 sampled symptomatic Pyrus trees which provides evidence that PeLV and PBCVd are not present in New Zealand
