Yellow Dwarf Virus

Barley yellow dwarf disease, a ubiquitous virus disease of cereal crops worldwide, is caused by a group of related, single-stranded RNA viruses assigned to Luteovirus (Barley yellow dwarf virus [BYDV] spp. PAV, PAS, MAV, and GAV) or Polerovirus (Cereal yellow dwarf virus-RPV) genera or unassigned to a genera (BYDV-SGV, BYDV-RMV, and BYDV-GPV) in the family Luteoviridae (1). Incidence of BYDV in cereal crops (e.g., barley, wheat, and oats) was high, and in recent years, reached epidemic levels in many regions of the Czech Republic. BYDV-PAV and BYDV-PAS have been identified in Czech cereal crops (2,4). Surveys of the incidence of BYDV were carried out using ELISA (SEDIAG SAS, Longvic, France) and one-step reverse transcription (RT)-PCR (Qiagen, Hilden, Germany) (2) during 2007 and 2008. Samples (125) were collected from different fields around the Czech Republic and 96 were BYDV positive. Three of the field isolates, CZ-6815, CZ-1561, and CZ-10844, from oat (Avena sativa; cv. Auron), winter wheat (Triticum aestivum; cv. Apache), and winter barley (Hordeum vulgare; cv. Merlot), respectively, were identified as BYDV-MAV by sequencing of the RT-PCR product (641-bp fragment) used to identify BYDV, which spanned 2839–3479 of the BYDV genome (GenBank Accession Nos. EF043235 and NC_002160) (2). The partial coat protein gene sequence of 483 nt was compared with the available sequences of 12 BYDV-PAV isolates (PAV-JP, PAV-NY, PAV-ILL, PAV-AUS, PAV-WG2, PAV-whG4y3, PAV-on21-4, Tahoe1, CA-PAV, HB3, FH3, and MA9501); nine BYDV-PAS isolates (PAS-129, PAS-64, WS6603, WG13, PAS-Tcb4-1, PASwaw5-9, FL2, PAS-Vd29, and PAS-MA9516); and six BYDV-MAV isolates (MAV-CA, MAV-PS1X1, MAV-Alameds268, LMB2a, SI-o4, and MAV-CN) by MEGA4 (3). Nucleotide and amino acid sequence identities for the three isolates ranged from 92.9 to 99.4% and 88.0 to 95.8%, respectively, for available BYDV-MAV isolates; 76.8 to 78.2% and 62.7 to 67.6%, respectively, for available BYDV-PAS isolates; and 77.6 to 79.3% and 65.5 to 70.4%, respectively, for available PAV isolates. The sequence data indicates that these isolates (CZ-6815, CZ-1561, and CZ10844; GenBank Accession Nos. FJ645747, FJ645758, and FJ645746, respectively) are BYDV-MAV. To my knowledge, this is the first record of BYDV-MAV in the Czech Republic. References: (1) C. J. D'Arcy and L. L. Domier. Page 891 in: Virus Taxonomy-8th Report of the ICTV. C. M.

Dh Lines

Barley yellow dwarf (BYD) is a major virus disease which dramatically reduces wheat yield. Introducing BYD resistance genes into commercial varieties has been proven to be effective in reducing damage caused by barley yellow dwarf virus (BYDV). However, only one major resistance gene is readily deployable for breeding; Bdv2 derived from Thinopyrum intermedium is deployed as a chromosomal translocation. In this study, a double haploid (DH) population was developed from a cross between XuBYDV (introduced from China showing very good resistance to BYD) and H-120 (a BYD-sensitive Chinese accession), and was used to identify QTL for BYD resistance. The population was genotyped using an Infinium iSelect bead chip array targeting 90K gene-based SNPs. The disease resistance of DH lines inoculated with BYDV was assessed at the heading stage. The infections were assessed by tissue blot immunoassay (TBIA). Three new QTL were identified on chromosomes 5A, 6A, and 7A for both symptom and TBIA, with all three resistance alleles being inherited from XuBYDV. Some DH lines with the resistance alleles from all three QTL showed high level resistance to BYD. These new QTL will be useful in breeding programs for pyramiding BYD resistance genes.
