“…However, a conserved motif, C-2X-C (aa 410-413), is found at the HC-Pro N-terminal regions of SCSMV-PAK, TriMV [24] and mite-transmitted tritimoviruses at the location of the motif K-(I, L)-(T, S)-C, an important motif associated with aphid transmission in the genus Potyvirus. Two cysteine residues within this motif were determined to be essential for transmission of WSMV by eriophyid mites [25]. The putative protease motif C-71X-H (aa 715-787) is found at the C-terminal region of the SCSMV HC-Pro protein.…”

The complete genomic sequence of a Pakistani isolate of Sugarcane streak mosaic virus (SCSMV-PAK) is determined to be 9782 nucleotides in length, excluding the 3' poly(A) tail, and it comprises a large open reading frame encoding a polyprotein of 3130 amino acid residues. The deduced polyprotein is likely to be cleaved at nine putative protease sites by three viral proteases to ten mature proteins. Conserved motifs of orthologous proteins of other potyviruses are identified in corresponding positions of SCSMV-PAK. The genomic organization is virtually identical to the genera Ipomovirus, Potyvirus, Rymovirus, and Tritimovirus in the family Potyviridae. Sequence analyses indicate that the SCSMV-PAK genomic sequence is different from those of Sugarcane mosaic virus and Sorghum mosaic virus, two viruses with very similar symptoms and host range to SCSMV-PAK. SCSMV-PAK shares 52.7% identity with Triticum mosaic virus (TriMV) and 26.4-31.5% identities with species of the existing genera and unassigned viruses in the Potyviridae at the polyprotein sequence level. Phylogenetic analyses of the polyprotein and deduced mature protein amino acid sequences reveal that SCSMV, together with TriMV, forms a distinct group in the family at the genus level. Therefore, SCSMV should represent a new genus, Susmovirus, in the Potyviridae.

“…The region missing from the BVY HC-Pro corresponds to the N-terminus of the Potyvirus orthologs and is involved in gene silencing and probably vector transmission (Revers et al, 1999;Stenger et al, 2006;UrcuquiInchima et al, 2001;Young et al, 2007). In addition to the much smaller HC-Pro mature protein, BVY HC-Pro is lacking conserved motifs involved in genome amplification and systemic movement (Urcuqui-Inchima et al, 2001).…”

“…It has been shown that acaricide treatments, control of volunteer wheats, tillage and environmental factors can affect mite survival and incidence of virus infection Exp Appl Acarol (2010) 51:3-30 11 (Harvey et al 1998;Thomas and Hein 2003;Jiang et al 2005;Coutts et al 2008). In addition, biomolecular methods changing the virus region can effectively reduce the efficiency of vector transmission (Stenger et al 2006;Young et al 2007). Great attention has been also paid to the discovery and breeding of WSMV-and WCM-resistant wheat varieties as a promising methods for controlling this mite-vectored disease (e.g.…”

During the last 12 years, considerable research attention has been paid to 12 pathogens transmitted by nine eriophyoid vectors, although only scarce concern has been paid to understanding the intimate mechanisms of virus transmission (Young et al 2007) and virus detection within the mite body (Latha and Doraiswamy 2008).…”

Fundamental knowledge on the morphology, biology, ecology, and economic importance of Eriophyoidea has been exhaustively compiled by Lindquist et al. (Eriophyoid mites--their biology, natural enemies and control; Elsevier, 1996). Since that time, the number of recognized species and the economic importance of the taxon have increased substantially. The aim of this paper is to analyze and briefly review new findings from eriophyoid mites' literature after Lindquist et al. book, stressing persistent gaps and needs. Much recent attention has been given to sampling and detection, taxonomy and systematics, faunistic surveys, internal morphology, rearing techniques, biological and ecological aspects, biomolecular studies, and virus vectoring. Recommendations are made for integrating research and promoting broader dissemination of data among specialists and non-specialists.
