    Abstract:
    A virus identified as "apple green crinkle associated virus" (AGCaV) was isolated from Aurora Golden Gala apple showing severe symptoms of green crinkle disease. Evidence was obtained of a potential causal relationship to the disease. The viral genome consists of 9266 nucleotides, excluding the poly(A) tail at the 3'-terminus. It has a genome organization similar to that of members of the species Apple stem pitting virus (ASPV), the type species of the genus Foveavirus, family Betaflexiviridae. ORF1 of AGCaV encodes a replicase-complex polyprotein with a molecular mass of 247 kDa; the proteins of ORFs 2, 3, and 4 (TGB proteins) are estimated to be 25.1 kDa, 12.8 kDa, and 7.4 kDa, respectively; and ORF5 encodes the CP, with an estimated molecular mass of 43.3 kDa. Interestingly, AGCaV utilizes different stop codons for ORF1, ORF3, and ORF5 compared to the ASPV type isolate PA66, and between the two viruses, six distinct indel events were observed within ORF5. AGCaV has four non-coding regions (NCRs), including a 5'-NCR (60 nt), a 3'-NCR (134 nt), and two intergenic (IG) NCRs: IG-NCR1 (69 nt) and IG-NCR2 (91 nt). A conserved stable hairpin structure was identified in the variable 5'-NCR of members of the genus Foveavirus. AGCaV may be a variant or strain of ASPV with unique biological properties, but there is evidence that it may be a distinct putative foveavirus.
