Greenbug Resistance

SUMMARYGreenbug infestations to sorghum can cause severe and above economic threshold damage in the Great Plains of the United States. The current study was conducted to identify quantitative trait loci (QTLs) and potential candidate genes residing within the QTL region responsible for greenbug resistance in an advanced mapping population. Inter-crossed populations are useful in detecting QTLs tightly linked to genetic markers with high resolution. In the current study, QTLs responsible for greenbug resistance in sorghum were mapped using an inter-cross population derived from two parents, BTx623 (greenbug-susceptible line) and PI 607900 (greenbug-resistant line). Molecular markers for 115 loci were used to construct a linkage map which eventually facilitated tagging portions of the sorghum genome regions responsible for greenbug resistance. The molecular genetic map covered all the chromosomes of sorghum with a total genome length of 963·0 cM. The advanced mapping population revealed and confirmed the location of greenbug resistance loci, which explained a high phenotypic variation from 72·9 to 80·9% of greenbug resistance. The loci for greenbug resistance were mapped to the region flanked by markers Starssbnm 93 and Starssbnm 102 on chromosome 9 with an increased allelic effect from the resistant parent. The locations of these loci were compared with a previous study on QTL analysis using an F2 mapping population. The results from the present study were in agreement with the findings in the F2 QTL analysis and identified QTLs had a better confidence interval. The markers/QTLs identified from the current study can be effectively utilized in marker-assisted selection and map-based cloning experiments.

A molecular genetic map was constructed and an electrophoretic karyotype was resolved for Cochliobolus sativus, the causal agent of spot blotch of barley and wheat. The genetic map consists of 27 linkage groups with 97 amplified fragment length polymorphism (AFLP) markers, 31 restriction fragment length polymorphism (RFLP) markers, two polymerase chain reaction amplified markers, the mating type locus (CsMAT), and a gene (VHv1) conditioning high virulence on barley cv. Bowman. These linkage groups covered a map distance of 849 cM. The virulence gene VHv1 cosegregated with six AFLP markers and was mapped on one of the major linkage groups. Fifteen chromosome-sized DNAs were resolved in C. sativus isolates ND93-1 and ND90Pr with contour-clamped homogeneous electric field (CHEF) electrophoresis combined with telo-mere probe analysis of comigrating chromosome-sized DNAs. The chromosome sizes ranged from 1.25 to 3.80 Mbp, and the genome size of the fungus was estimated to be approximately 33 Mbp. By hybridizing genetically mapped RFLP and AFLP markers to CHEF blots, 25 of the 27 linkage groups were assigned to specific chromosomes. The barley-specific virulence locus VHv1 was localized on a chromosome of 2.80 Mbp from isolate ND90Pr in the CHEF gel. The total map length of the fungus was estimated to be at least 1,329 cM based on the map distance covered by the linked markers and the estimated gaps. Therefore, the physical to genetic distance ratio is approximately 25 kb/cM. Construction of a high-resolution map around target loci will facilitate the cloning of the genes conferring virulence and other characters in C. sativus by a map-based cloning strategy.
