Microdissection and Chromosome Painting of the Alien Chromosome in an Addition Line of Wheat - Thinopyrum intermedium
In this study, chromosome painting was developed and used to identify alien chromosomes in TAi-27, a wheat--Thinopyrum intermedium addition line, and the chromosomes of the three different genomes of Th. Intermedium. The smallest alien chromosome of TAi-27 was microdissected and its DNA amplified by DOP-PCR was used as a probe to hybridize with metaphase chromosomes of TAi-27 and Th. intermediu...
متن کاملMapping barley genes to chromosome arms by transcript profiling of wheat-barley ditelosomic chromosome addition lines.
Wheat-barley disomic and ditelosomic chromosome addition lines have been used as genetic tools for a range of applications since their development in the 1980s. In the present study, we used the Affymetrix Barley1 GeneChip for comparative transcript analysis of the barley cultivar Betzes, the wheat cultivar Chinese Spring, and Chinese Spring - Betzes ditelosomic chromosome addition lines to phy...
متن کاملExpressed sequence tag-PCR markers for identification of alien barley chromosome 2H in wheat.
We developed EST-PCR markers specific to barley chromosome 2H, for the purpose of effectively tracing alien chromosomes or chromosome parts in the wheat genetic background. The target alien chromosome 2H confers high resistance to pre-harvest sprouting, which is a worldwide natural disaster in wheat. A total of 120 primer pairs were selected by combining the wheat group 2 chromosomes of th...
متن کاملSelection and identification of a spontaneous alien chromosome translocation in wheat.
A wheat (Triticum aestivum L. emend Thell) disomic addition line (2n = 6x = 44), SH1-152-2, with a pair of Elytrigia pontica (Podp.) Holub 2n = 10x = 70 [syn. Agropyron elongatum (Host) P.B.] chromosomes controlling blue aleurone color was crossed with a short-statured spring wheat ;Sonora 64' (T. aestivum). Isoline pairs of blue-disomic addition lines and nonblue euploid lines were produced by...
متن کاملTranscriptome analysis and physical mapping of barley genes in wheat-barley chromosome addition lines.
Wheat-barley chromosome addition lines are useful genetic resources for a variety of studies. In this study, transcript accumulation patterns in Betzes barley, Chinese Spring wheat, and Chinese Spring-Betzes chromosome addition lines were examined with the Barley1 Affymetrix GeneChip probe array. Of the 4014 transcripts detected in Betzes but not in Chinese Spring, 365, 271, 265, 323, 194, and ...
