The Development of 7E Chromosome-Specific Molecular Markers for Thinopyrum elongatum Based on SLAF-seq Technology
Thinopyrum elongatum is an important relative of wheat, it is favored by many researchers for the disease resistant genes that exist in its E genome. Some studies have showed that the 7E chromosome of Th. elongatum contains resistance genes related to Fusarium head blight and wheat rust. Therefore, developing 7E chromosome-specific molecular markers linked to resistance genes will provide an im...
متن کاملRAPD and ISSR-assisted identification and development of three new SCAR markers specific for the Thinopyrum elongatum E (Poaceae) genome.
Diploid Thinopyrum elongatum, a wild relative of wheat, contains many agronomically desirable traits and has potential for increasing genetic variability and introducing desirable characters in this crop. Few molecular markers are available for rapid screening of T. elongatum genome segments in the wheat genetic background. We used 36 RAPD primers and 33 ISSR primers to screen for polymorp...
متن کاملIdentification of supernumerary marker chromosomes derived from chromosomes 5, 6, 19, and 20 using FISH.
A large number of cases with supernumerary marker chromosomes (SMCs) should be compared to achieve a better delineation of karyotype-phenotype correlations. Here we present four phenotypically abnormal patients with autosomal marker chromosomes analysed by fluorescence in situ hybridisation using centromeric, telomeric, and unique sequence probes, as well as forward and reverse painting. We als...
متن کاملAnalysis of the Thinopyrum elongatum Transcriptome under Water Deficit Stress
The transcriptome of Thinopyrum elongatum under water deficit stress was analyzed using RNA-Seq technology. The results showed that genes involved in processes of amplification of stress signaling, reductions in oxidative damage, creation of protectants, and roots development were expressed differently, which played an important role in the response to water deficit. The Th. elongatum transcrip...
متن کاملChromosome identification by new molecular markers and genomic in situ hybridization in the Triticum-Secale-Thinopyrum trigeneric hybrids.
It is very important to use chromosome-specific markers for identifying alien chromosomes in advanced generations of distant hybridization. The chromosome-specific markers of rye and Thinopyrum elongatum, as well as genomic in situ hybridization, were used to identify the alien chromosomes in eight lines that were derived from the crossing between Triticum trititrigia (AABBEE) and triticale (AA...
