Abstract (sommario):

Mosaic is one of the most important sugarcane diseases, caused by single or compound infection of Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (SrMV), and/or Sugarcane streak mosaic virus (SCSMV). The compound infection of mosaic has become increasingly serious in the last few years. The disease directly affects the photosynthesis and growth of sugarcane, leading to a significant decrease in cane yield and sucrose content, and thus serious economic losses. This review covers four aspects of sugarcane mosaic disease management: first, the current situation of sugarcane mosaic disease and its epidemic characteristics; second, the pathogenicity and genetic diversity of the three viruses; third, the identification methods of mosaic and its pathogen species; and fourth, the prevention and control measures for sugarcane mosaic disease and potential future research focus. The review is expected to provide scientific literature and guidance for the effective prevention and control of mosaic through resistance breeding in sugarcane.

Abstract (sommario):

Leaf samples from 693 sugarcane plants showing mosaic symptoms were collected in 2001, 2002, and 2003 at 12 locations within the Louisiana sugarcane industry. Virus isolates associated with the diseased plants were identified using reverse-transcriptase polymerase chain reaction (RT-PCR) to distinguish between Sugarcane mosaic virus (SCMV) and Sorghum mosaic virus (SrMV). No SCMV strain was associated with any diseased plant collected during the survey. RT-PCR-based restriction fragment length polymorphism (RFLP) analysis showed that SrMV strains I, H, and M were associated with 67, 10, and 2% of the plants with mosaic symptoms, respectively. In previous surveys conducted between 1978 and 1995, over 90% of the plants sampled were infected with SrMV strain H. The remaining plants mostly were infected with SrMV strain I, except for an occasional sample with SrMV strain M. RT-PCR showed that approximately 13% of the samples collected between 2001 and 2003 were infected with SrMV, but the RFLP banding pattern did not match any described strain. Twelve plants were co-infected by two SrMV strains and two plants by three SrMV strains. No RT-PCR product was produced by either the SCMV- or the SrMV-specific RT-PCR primer set for 8% of the plants showing mosaic symptoms, suggesting that another virus may cause sugarcane mosaic in Louisiana.

Abstract (sommario):

Sugarcane leaves with mosaic symptoms were collected in 2006–07 in Tucumán (Argentina) and analyzed by reverse-transcriptase polymerase chain reaction (RT-PCR) restriction fragment length polymorphism (RFLP) and sequencing of a fragment of the Sugarcane mosaic virus (SCMV) and Sorghum mosaic virus (SrMV) coat protein (CP) genes. SCMV was detected in 96.6% of samples, with 41% showing the RFLP profile consistent with strain E. The remaining samples produced eight different profiles that did not match other known strains. SCMV distribution seemed to be more related to sugarcane genotype than to geographical origin, and sequence analyses of CP genes showed a greater genetic diversity compared with other studies. SrMV was detected in 63.2% of samples and most of these were also infected by SCMV, indicating that, unlike other countries and other Argentinean provinces, where high levels of co-infection are infrequent, co-existence is common in Tucumán. RFLP analysis showed the presence of SrMV strains M (68%) and I (14%), while co-infection between M and H strains was present in 18% of samples. Other SCMV subgroup members and the Sugarcane streak mosaic virus (SCSMV) were not detected. Our results also showed that sequencing is currently the only reliable method to assess SCMV and SrMV genetic diversity, because RT-PCR-RFLP may not be sufficiently discriminating.

Abstract (sommario):

Sugarcane mosaic virus [SCMV (Potyvirus sugarcane mosaic virus)] is an ssRNA virus that negatively affects yield in maize (Zea mays) worldwide. Resistance to SCMV is controlled primarily by a single dominant gene (Scm1). The goal of this study was to identify sweet corn (Z. mays) inbreds that demonstrate resistance to SCMV, confirm the presence of genomic regions previously identified in maize associated with resistance, and identify other resistant loci in sweet corn. Eight plants from each of 563 primarily sweet corn inbred lines were tested for SCMV resistance. Plants were inoculated 14 d after planting and observed for signs of infection 24 d after planting. A subset of 420 inbred lines were genotyped using 7504 high-quality genotyping-by-sequencing single-nucleotide polymorphism markers. Population structure of the panel was observed, and a genome-wide association study was conducted to identify loci associated with SCMV resistance. Forty-six of the inbreds were found to be resistant to SCMV 10 d after inoculation. The Scm1 locus was confirmed with the presence of two significant loci on chromosome 6 (P = 2.5 × 10−8 and 1.6 × 10−8), 5 Mb downstream of the Scm1 gene previously located at Chr6: 14194429.14198587 and the surrounding 2.7-Mb presence–absence variation. We did not identify other loci associated with resistance. This research has increased information on publicly available SCMV-resistant germplasm useful to future breeding projects and demonstrated that SCMV resistance in this sweet corn panel is driven by the Scm1 gene.

Abstract (sommario):

As one of the critical diseases of sugarcane, sugarcane mosaic disease can lead to serious decline in stalk yield and sucrose content. It is mainly caused byPotyvirus sugarcane mosaic virus(SCMV) and/orSorghum mosaic virus(SrMV), with additional differences in viral strains. RNA interference (RNAi) is a novel strategy for producing viral resistant plants. In this study, based on multiple sequence alignment conducted on genomic sequences of different strains and isolates of SrMV, the conserved region of coat protein (CP) genes was selected as the target gene and the interference sequence with size of 423 bp in length was obtained through PCR amplification. The RNAi vector pGII00-HACP with an expression cassette containing both hairpin interference sequence andcp4-epspsherbicide-tolerant gene was transferred to sugarcane cultivar ROC22 viaAgrobacterium-mediated transformation. After herbicide screening, PCR molecular identification, and artificial inoculation challenge, anti-SrMV positive transgenic lines were successfully obtained. SrMV resistance rate of the transgenic lines with the interference sequence was 87.5% based on SrMV challenge by artificial inoculation. The genetically modified SrMV-resistant lines of cultivar ROC22 provide resistant germplasm for breeding lines and can also serve as resistant lines having the same genetic background for study of resistance mechanisms.

Abstract (sommario):

<p>Sugarcane disease surveys were conducted from 2010 to 2014 at major sugarcane growing areas in 5 provinces (Nakhon Pathom, Kanchanaburi, Udon Thani, Khon Kaen, Nakhon Ratchasima) and germplasm collection fields. Random samples of the virus-like sugarcane leaves obtained from the surveyed areas suggested yellow streak mosaic symptoms. Direct antigen coating ELISA using locally produced SCSMV antiserum, revealed widespread incidence of SCSMV in the major sugarcane growing areas and the germplasm collection fields, ranging from 43.48-90.91% and 54.17-100% respectively. The virus isolate from sugarcane in Kamphaeng Saen, Nakhon Pathom, designated as THA-NP3, was characterized by genomic sequencing. Complete genome of THA-NP3 (JN163911) contained 9,781 nucleotides, excluding 3¢ Poly (A) tail which encoded a polyprotein of 3,130 amino acid residues comprising 10 functional proteins, namely P1, HC-Pro, P3, 6K1, CI, 6K2, NIa-VPg, NIa-Pro, NIb and CP. Sequence comparisons revealed that THA-NP3 showed 97.84% nucleotide identity to JP2 (JF488065) from China and 81.39-97.78% nucleotide identities to other recorded SCSMV sequences. Detection for the presence of CP gene by RT-PCR indicated 1094 bp containing 846 bp of the CP coding region. Analysis of the CP gene revealed genetic variation of 58 Thai SCSMV isolates, 86.17-100% nucleotide identities among them and 85.70-99.29% nucleotide identities to SCSMV isolates from other countries. Recombination events existed in the CP coding regions between two distinct sub-populations, the germplasm isolates and the farmers’ field isolates. These results suggested the incidence of SCSMV variants between the farmers’ fields and the germplasm collection fields. <strong></strong></p>

Abstract (sommario):

Sugarcane mosaic virus (SCMV) is the causal agent of sugarcane mosaic disease (SMD) in Brazil; it is mainly controlled by using resistant cultivars. Studies on the changes in sugarcane transcriptome provided the first insights about the molecular basis underlying the genetic resistance to SMD; nonetheless, epigenetic modifications such as cytosine methylation is also informative, considering its roles in gene expression regulation. In our previous study, differentially transcribed fragments (DTFs) were obtained using cDNA-amplified fragment length polymorphism by comparing mock- and SCMV-inoculated plants from two sugarcane cultivars with contrasting responses to SMD. In this study, the identification of unexplored DTFs was continued while the same leaf samples were used to evaluate SCMV-mediated changes in the cytosine methylation pattern by using methylation-sensitive amplification polymorphism. This analysis revealed minor changes in cytosine methylation in response to SCMV infection, but distinct changes between the cultivars with contrasting responses to SMD, with higher hypomethylation events 24 and 72 h post-inoculation in the resistant cultivar. The differentially methylated fragments (DMFs) aligned with transcripts, putative promoters, and genomic regions, with a preponderant distribution within CpG islands. The transcripts found were associated with plant immunity and other stress responses, epigenetic changes, and transposable elements. The DTFs aligned with transcripts assigned to stress responses, epigenetic changes, photosynthesis, lipid transport, and oxidoreductases, in which the transcriptional start site is located in proximity with CpG islands and tandem repeats. Real-time quantitative polymerase chain reaction results revealed significant upregulation in the resistant cultivar of aspartyl protease and VQ protein, respectively, selected from DMF and DTF alignments, suggesting their roles in genetic resistance to SMD and supporting the influence of cytosine methylation in gene expression. Thus, we identified new candidate genes for further validation and showed that the changes in cytosine methylation may regulate important mechanisms underlying the genetic resistance to SMD.

Abstract (sommario):

SCMV (Sugarcane Mosaik Virus) is sugarcane crop disease resulting in chlorosis in leaves with the formation of the colors yellow and green intermittents. Based on survey information obtained that the air observation of all varieties of sugarcane was already stricken with the virus SCMV. Even the most formidable attack is on PS881 varieties with the intensity of the attacks reached 80%, so that it is estimated will lose up to 40% of the harvest. The sugarcane is virus free can be obtained via organogenesis in tissue culture method directly on the apical meristem, somatic embryogenesis at, and also with the addition of khemoterapeutan (acyclovir).The workings of the khemoterapi materials are the chemotherapi will interfere with replication and synthesis of genetic material of the virus but also cause the same effect against the mechanism of synthesis of nuklet acid on plants hosts. This research aims to find the best concentration and exposure time the most good in eliminating viruses SCMV in the apical bud culture of sugarcane PS881, using the antiviral acyclovir in conditions of invitro, so that the resulting plant will be virus free. The methods used to detect the presence of the virus by using the two ways, the first is by serology test through the protein content of the virus / checking nucleic acid virus with ELISA and the second is by RT-PCR. The results of the analysis showed that the interaction between the concentration of chemotherapy and exposure time produces the best treatment in eliminating the virus was . treatment with acyclovirc oncentration of 20 ppm and exposure time of 5 weeks.

Abstract (sommario):

The gene action of 2 sugarcane mosaic virus (SCMV) resistance loci in maize, Scmv1 and Scmv2, was evaluated for potyvirus resistance in an isogenic background. All 4 homozygous and 5 heterozygous isogenic genotypes were produced for introgressions of the resistant donor (FAP1360A) alleles at both loci into the susceptible parent (F7) genetic background using simple sequence repeat markers. For SCMV and maize dwarf mosaic virus (MDMV), virus symptoms appeared rapidly in the 3 homozygous genotypes, with susceptibility alleles fixed at 1 or both loci. Although the 9 isogenic genotypes revealed a high level of resistance to Zea mosaic virus (ZeMV), the same 3 homozygous genotypes were only partially resistant. This indicates that 1 resistance gene alone is not sufficient for complete resistance against SCMV, MDMV, and ZeMV. Scmv1 showed strong early and complete dominant gene action to SCMV, but it gradually became partially dominant. Scmv2 was not detected at the beginning, showing dominant gene action initially and additive gene action at later stages. Both genes interacted epistatically (for a high level of resistance, at least 1 resistance allele at each of both loci is required). This implies that double heterozygotes at the 2 loci are promising for producing SCMVresistant hybrids. Results are discussed with respect to prospects for isolation of SCMV and MDMV resistance genes.

Abstract (sommario):

Banana plants are hosts to a large number of Banana streak virus (BSV) species. However, diagnostic methods for BSV are inadequate because of the considerable genetic and serological diversity among BSV isolates and the presence of integrated BSV sequences in some banana cultivars which leads to false positives. In this study, a sequence-nonspecific, rolling-circle amplification (RCA) technique was developed and shown to overcome these limitations for the detection and subsequent characterization of BSV isolates infecting banana. This technique was shown to discriminate between integrated and episomal BSV DNA, specifically detecting the latter in several banana cultivars known to contain episomal or integrated sequences of Banana streak Mysore virus (BSMyV), Banana streak OL virus (BSOLV), and Banana streak GF virus (BSGFV). Using RCA, the presence of BSMyV and BSOLV was confirmed in Australia, while BSOLV, BSGFV, Banana streak Uganda I virus (BSUgIV), Banana streak Uganda L virus (BSUgLV), and Banana streak Uganda M virus (BSUgMV) were detected in Uganda. This is the first confirmed report of episomally-derived BSUglV, BSUgLV, and BSUgMV in Uganda. As well as its ability to detect BSV, RCA was shown to detect two other pararetroviruses, Sugarcane bacilliform virus in sugarcane and Cauliflower mosaic virus in turnip.

Abstract (sommario):

The Sugarcane mosaic virus (SCMV), a maize pathogen epidemic worldwide, is the causal agent of common mosaic, one of the most important viral diseases in Brazil. In this study, we mapped and characterized quantitative trait loci (QTL) conferring resistance to SCMV in a maize population consisting of 127 F2:3 families from the cross between two Brazilian maize inbred lines, L18 (resistant) × L19 (susceptible). Field trials were carried out in two years to evaluate the F2:3 families according to a resistance score after artificial inoculation. QTLs were detected via composite interval mapping, using a linkage map based on 82 SSRs, 3 CAPS and 296 SNPs. The heritability ranged from 73.68 to 95.16% and SCMV resistance QTLs were consistently identified on chromosomes 1 and 3, showing minor and major effects, respectively. The major QTL on chromosome 3 explained a large proportion of the genetic variance, being 50 and 70% in year 1 and 2, respectively, while the minor QTL on chromosome 1 explained 11 and 8% in year 1 and 2, respectively. The SNP marker co-localized with the major QTL peak on chromosome 3 and its right flanking marker are positioned inside the predicted gene GRMZM2G122443 encoding a glucosidase II, and the left flanking marker inside the GRMZM2G140537 that encodes a protein tyrosine kinase. Moreover, within this QTL region there are also the GRMZM2G160902 and GRMZM2G122481 predicted genes, encoding a bZIP transcription factor and a cytochrome C oxidase, respectively. The colocalization with this major effect QTL suggests a putative involvement of these candidate genes with maize responses to SCMV resistance, but further functional studies are required for such validation. Our results provide resistance source and genomic target for marker-assisted breeding aiming the development of maize resistant cultivars to SCMV.

Abstract (sommario):

<p>Penggunaan benih bebas virus merupakan salah satu cara pengendalian penyakit virus. Jaringan tanaman dapat dibebaskan dari virus melalui aplikasi teknik eliminasi virus, seperti termoterapi, kemoterapi, kultur meristem, dan krioterapi. Tujuan penelitian ini adalah untuk menguji respon varietas tebu terhadap perlakuan teknik kultur meristem dan kemoterapi dengan bahan antiviral, serta untuk mengetahui efektivitasnya dalam mengeliminasi virus <em>sugarcane streak mosaic virus</em> (SCSMV) pada tebu. Penelitian ini dilakukan pada April−November 2015 di Laboratorium Kultur Jaringan, Balai Besar Penelitian dan Pengembangan Bioteknologi dan Sumberdaya Genetik Pertanian dan Laboratorium Virologi, Fakultas Pertanian, Universitas Gadjah Mada. Penelitian terdiri atas tiga tahap, yaitu 1) Deteksi virus dari tanaman induk, 2) Aplikasi teknik kultur meristem dan kemoterapi, serta 3) Indeksing virus. Bahan tanaman yang digunakan adalah sebelas varietas tebu (GMP3, PS865, dan Kentung asal Bogor, PS862 dan Cening asal Cirebon, PS881 asal Jember, PSJK922 asal Malang, serta PS864, PS881, PSJK922, PSJT941 asal Pati). Deteksi virus dilakukan secara RT-PCR dengan primer universal MJ dan primer spesifik SCSMV. Bahan antiviral yang digunakan untuk kemoterapi adalah Ribavirin (0 dan 25 µg/l). Hasil uji RT-PCR menggunakan primer universal MJ menunjukkan bahwa empat varietas (GMP3 asal Bogor, PS864 dan PSJT941 asal Pati, serta Cening asal Cirebon) terinfeksi oleh <em>Potyvirus</em>. Empat varietas lainnya (PS862 asal Cirebon, PS881 asal Jember, PSJK922 asal Malang, dan Kentung asal Bogor) terbukti terserang virus SCSMV berdasarkan uji RT-PCR dengan primer spesifik. Seluruh meristem mampu beregenerasi membentuk tunas. Penggunaan Ribavirin 25 µg/l tidak menyebabkan penurunan daya tumbuh meristem (50−100%), bahkan seluruh varietas mampu bermultiplikasi tunasnya dibandingkan dengan kontrol yang hanya memiliki daya tumbuh 0−100%, dan tidak semua varietas mampu bermultiplikasi tunasnya. Secara tunggal, aplikasi teknik kultur meristem tidak mampu mengeliminasi virus SCSMV, namun jika dikombinasikan dengan perlakuan kemoterapi maka virus SCSMV dapat tereliminasi dengan efikasi sebesar 44,4%.</p><p> </p><p>The use of virus-free seedling is an option for controllingviraldisease that can be obtained through the application of viral elimination method. Plant tissues can be eliminated from virus infection by applying virus thermotherapy, chemotherapy, meristem culture, and cryotherapy. The research objectives were to examine the response of sugarcane varieties to meristem culture treatments and antiviral agent and also to determine the efficacy rate of both techniques in eliminating SCSMV disease. The study was conducted atTissuseCulture Laboratory, Indonesian Center for Agricultural Biotechnology and Genetic Resources Research andDevelpoment, and also at Virology Laboratory, Faculty of Agriculture, Gadjah Mada University. This study consisted of three activities: 1) Virus detection of the mother plants, 2) Application of meristem culture and chemotherapy, and 3) Virus indexing. The plant material used was eleven varieties of sugarcane (GMP3, PS865, and Kentung from Bogor, PS862 and Cening from Cirebon, PS881 from Jember, Malang PSJK922 origin, as well as the PS864, PS881, PSJK922, PSJT941 from Pati). Virus detection was performed by RT-PCR assay with universal primer of MJ and specific primers of SCSMV. Antiviral used for chemotherapy was Ribavirin (0 and 25 µg/l). The result of RT-PCR using universal primers MJ showed that four varieties (GMP3 from Bogor, PS864 and PSJT941 from Pati, and Cening from Cirebon) were infected by Potyvirus. Based on RT-PCR assay with specific primer, four other varieties (PS862 from Cirebon, PS881 from Jember, PSJK922 from Malang, and Kentung from Bogor) were infected by SCSMV. All of meristems were able to regenerate to form shoots. The use of Ribavirin (25µg/l) did not decrease the growth rate of meristems and the shoots of all of the varieties could be multipied compared to control where the shoots could not be multiplied in all varietis. The application of meristem culture technique was not able to eliminate the SCSMV, but when it was combined with chemotherapy treatment, the SCSMV virus could be eliminated with the efficacy rate of 44.4%.</p><p> </p>

Abstract (sommario):

Maize lethal necrosis (MLN) occurs when maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV) co-infect maize plant. Yield loss of up to 100% can be experienced under severe infections. Identification and validation of genomic regions and their flanking markers can facilitate marker assisted breeding for resistance to MLN. To understand the status of previously identified quantitative trait loci (QTL)in diverse genetic background, F3 progenies derived from seven bi-parental populations were genotyped using 500 selected kompetitive allele specific PCR (KASP) SNPs. The F3 progenies were evaluated under artificial MLN inoculation for three seasons. Phenotypic analyses revealed significant variability (P ≤ 0.01) among genotypes for responses to MLN infections, with high heritability estimates (0.62 to 0.82) for MLN disease severity and AUDPC values. Linkage mapping and joint linkage association mapping revealed at least seven major QTL (qMLN3_130 and qMLN3_142, qMLN5_190 and qMLN5_202, qMLN6_85 and qMLN6_157 qMLN8_10 and qMLN9_142) spread across the 7-biparetal populations, for resistance to MLN infections and were consistent with those reported previously. The seven QTL appeared to be stable across genetic backgrounds and across environments. Therefore, these QTL could be useful for marker assisted breeding for resistance to MLN.

Abstract (sommario):

Sugarcane mosaic virus (SCMV) is the causal pathogen for a severe mosaic virus disease of maize worldwide. In our previous research, the maize resistance gene analog (RGA) Pic19 and its three cognate BAC contigs were mapped to the same region as the SCMV resistance gene Scmv1. Here we report the isolation and characterization of the Pic19R gene family members from the inbred line FAP1360A, which shows complete resistance to SCMV. Two primer pairs were designed based on the conserved regions among the known Pic19 paralogs and used for rapid amplification of cDNA ends of FAP1360A. Six full-length cDNAs, corresponding to the Pic19R-1 to -6 paralogs, were obtained. Three of them (Pic19R-1 to -3) had uninterrupted coding sequences and were, therefore, regarded as candidates for the Scmv1 gene. A total of 18 positive BAC clones harboring the Pic19R-2 to -5 paralogs were obtained from the FAP1360A BAC library and assembled into two BAC contigs. Two markers, tagging Pic19R-2 and -3 and Pic19R-4, were developed and used to genotype a high-resolution mapping population segregating solely for the Scmv1 locus. Although closely linked, none of these three Pic19R paralogs co-segregated with the Scmv1 locus. Analysis of the Pic19R family indicated that the Pic19R-1 paralog is identical to the known Rxo1 gene conferring resistance to rice bacterial streak disease and none of the other Pic19R paralogs seems to be involved in resistance to SCMV.
