Green Bridge

The wheat curl mite (WCM), Aceria tosichella, the vector of Wheat streak mosaic virus (WSMV), often survives the summer on volunteer wheat (Triticum aestivum) and may disperse from this “green bridge” in fall to newly planted winter wheat. Because some methods for managing volunteer wheat do not directly kill WCM, there is a window of risk for WCM and WSMV emigration after management has been applied. WCM survival in response to treatment of wheat by glyphosate, paraquat, stem cutting, and withholding water was measured in greenhouse experiments to determine how this window of risk for emigration varies with management. WCM populations on plants treated with paraquat or stem cutting decreased from the beginning of the sampling period. WCM populations on plants treated with glyphosate or that received no water increased up to 3 days after application and then decreased by 10 days after application. If glyphosate is used to manage volunteer wheat infested with WCM, it should be applied well before wheat is planted in fall. WCM in declining populations tended to be in an upright posture that could facilitate emigration via wind. The total green leaf area was strongly correlated with the number of WCM for treated plants and could be used in the field to predict the posttreatment survival of mites that pose a risk of emigration.

First Time

Wheat is one of the most important staple food crop .Wheat streak mosaic virus (WSMV) was first time reported in Nebraska in 1922 as "yellow mosaic". Since then, although sporadic in its appearance and severity, wheat streak mosaic has caused losses throughout North America, Europe, North Africa and Russia. The disease was probably present in other counties, but was not detected. WSM symptoms are characterized by a yellow leaf streaking or stippled pattern and stunting, head sterility, low test weights, and poor tillering and it is a seed born or mite born disease.WSMV is transmitted by eriophyid mite in both semi persistent and circulative manners. Mostly WSMV infects the crops belonging to family graminae or Poaceae (wheat, barley) and other alternate host of the WSMV are the grassy weeds or green bridge where wheat curl mite (WCM) over winters and lay eggs in the absents of the host. Wheat production in the Great Plains is also threatened by the newly discovered wheat viruses including Wheat mosaic virus and Triticum mosaic virus (TriMV). Both viruses closely match the life cycle of WSMV and are transmitted by WCM. Genome of WSMV contains positive sense ssRNA virions and one polyprotein. The tritimovirus which is approximately of 10kb in size

Reliable Detection

Wheat streak mosaic virus (WSMV) is transmitted by the wheat curl mite (WCM), Aceria tosichella. Immunofluorescent and dot-immunobinding assays were developed to detect the presence of WSMV in single WCM. Virus-specific immunofluorescent microscopy detected WSMV near the anterior end of viruliferous WCM. With dot-immunobinding assay, WSMV was detected in WCM fed on WSMV-infected wheat (Triticum aestivum) but not in WCM maintained on healthy plants. Both immunofluorescent and dot-immunobinding assays were sufficiently sensitive to detect WSMV in individual WCM, providing a means to determine the percentage of viruliferous WCM in field collections.

Wheat streak mosaic is a destructive disease of wheat caused by wheat streak mosaic virus. Wheat streak mosaic virus is vectored by the wheat curl mite (Eriophyes tulipae Keifer). A single dominant gene conditioning resistance to colonization by the mite vector was transferred from Aegilops squarrosa L. to a synthetic amphiploid (AC PGR 16635) and then to common wheat (Triticum aestivum L. em. Thell.) through backcrossing. Because of its origin, the transferred gene was probably located in the D genome. Monosomics 1D through 7D were crossed with a homozygous resistant line with the pedigree Norstar*4/AC PGR 16635. Both 41- and 42-chromosome F1 plants were identified and selfed to obtain F2 seed. The observed proportion of resistant and susceptible plants in 6 of the 7 F2 families from monosomics, and in all 7 of the F2s from disomics, did not deviate significantly from a 3:1 ratio. However, the proportion of resistant plants from the F2 of monosomic 6D was significantly (p < 0.01) in excess of this ratio and susceptible plants from this family were nullisomic for all or part of 6D. In crosses with standard ditelosomic stocks, telocentrics from a ditelosomic derivative of susceptible individual of this F2 paired with 6D(L) but failed to pair with 6D(S). The F2 of heterozygous resistant plants that were monotelodisomic for the long arm of 6D(L) segregated approximately 19 resistant to 1 susceptible, while those from monotelodisomics for the short arm segregated normally (3 resistant to 1 susceptible, p = 0.27). These data show that the gene Cmcl for mite resistance is located on the short arm of chromosome 6D. Key words: Aegilops squarrosa, wheat streak mosaic virus.

Partial Amphiploids

Thinopyrum intermedium (2n = 6x = 42, JJJsJsSS) is potentially a useful source of resistance to wheat streak mosaic virus (WSMV) and its vector, the wheat curl mite (WCM). Five partial amphiploids, namely Zhong 1, Zhong 2, Zhong 3, Zhong 4, and Zhong 5, derived from Triticum aestivum × Thinopyrum intermedium crosses produced in China, were screened for WSMV and WCM resistance. Zhong 1 and Zhong 2 had high levels of resistance to WSMV and WCM. The other three partial amphiploids, Zhong 3, 4, and 5, were resistant to WSMV, but were susceptible to WCM. Genomic in situ hybridization (GISH) using a genomic DNA probe from Pseudoroegneria strigosa (SS, 2n = 14) demonstrated that two partial amphiploids, Zhong 1 and Zhong 2, have almost the identical 10 Th. intermedium chromosomes, including four Js, four J, and two S genome chromosomes. Both of them carry two pairs of J and a pair of Js genome chromosomes and two different translocations that were not observed in the other three Zhong lines. The partial amphiploids Zhong 3, 4, and 5 have another type of basic genomic composition, which is similar to a reconstituted alien genome consisting of four S and four Js genome chromosomes of Th. intermedium (Zhong 5 has two Js chromosomes plus two Js–W translocations) with six translocated chromosomes between S and Js or J genomes. All three lines carry a specific S–S–Js translocated chromosome, which might confer resistance to barley yellow dwarf virus (BYDV-PAV). The present study identified a specific Js2 chromosome present in all five of the Zhong lines, confirming that a Js chromosome carries WSMV resistance. Resistance to WCM may be linked with J or Js chromosomes. The discovery of high levels of resistance to both WSMV and WCM in Zhong 1 and Zhong 2 offers a useful source of resistance to both the virus and its vector for wheat breeding programs.Key words: GISH, genomic composition, J, Js and S genomes, Thinopyrum intermedium, partial amphiploid, WSMV, WCM resistance.
