Project description:To screen the transcripts from Th. elongatum 7EL, we inoculated the spikes of translocation line Zhongke 1878 with Fusarium graminearum. We performed full-length transcriptome sequencing after 96 hours. To detect the expression level, we performed RNA-Seq on Zhongke 1878 after 12h, 24h, 48h and 96h.

Expression profiling of wheat heads from spring wheat Chinese Spring (CS) and CS-7EL (CS with additional chromosome arm 7EL from Thinopyrum elongatum), after inoculation with either water (mock inoculation) or Fusarium graminearum

Project description:The ditelocentric addition line CS-7EL of the spring wheat (Triticum aestivum) cultivar Chinese Spring (CS) contains the long arm of the chromosome 7E from Thinopyrum elongatum (CS-7EL), which confers high resistance to fusarium head blight. It is of great interest to breeders to integrate the resistance locus (loci) from Th. elongatum into commercial wheat varieties. The objectives of this study were to identify candidate genes expressed from the 7EL chromosome of CS-7EL, to develop 7EL-specific molecular markers, and to validate their usefulness to characterize recombination between one of the group 7 chromosomes of wheat and Th. elongatum. High-throughput sequencing of Fusarium graminearum-infected and control CS and CS-7EL cDNA libraries was performed using RNA-Seq. A stepwise bioinformatics strategy was applied to assemble the sequences obtained from RNA-Seq and to create a conservative list of candidate genes expressed from the foreign chromosome 7EL. PCR primer pairs were designed and tested for 135 candidate genes. A total of 48 expressed molecular markers specific for the chromosome 7EL were successfully developed. Screening of progenies from two BC1F2 families from the cross CS-7E(7D)×2*CSph1b showed that these markers are useful to characterize recombination events between the chromosomes 7D from wheat and 7E from Th. elongatum. Expression profiling of inoculated rachis from CS and CS-7EL heads sampled at 4 days after inoculation. Inoculation of all developed spikelets on each head at mid-anthesis was done with either water or F. graminearum strain DAOM 180378. Three biological replicates were done for each treatment, and 10 to 12 heads were inoculated per biological replicate.
