Extensive Pericentric Rearrangements in the Bread Wheat (Triticum aestivum L.) Genotype “Chinese Spring” Revealed from Chromosome Shotgun Sequence Data
The bread wheat (Triticum aestivum L.) genotype "Chinese Spring" ("CS") is the reference base in wheat genetics and genomics. Pericentric rearrangements in this genotype were systematically assessed by analyzing homoeoloci for a set of nonredundant genes from Brachypodium distachyon, Triticum urartu, and Aegilops tauschii in the CS chromosome shotgun sequence obtained from individual chromosome...
متن کاملChromosome Pairing in Hybrid Progeny between Triticum aestivum and Elytrigia elongata
In this study, the intergeneric hybrids F1, F2, BC1F1, BC1F2, and BC2F1 from Elytrigia elongata and Triticum aestivum crosses were produced to study their chromosome pairing behavior. The average E. elongata chromosome configuration of the two F1 hybrids agreed with the theoretical chromosome configuration of 21I+7II, indicating that the genomic constitution of this F1 hybrid was ABDStStEeEbEx....
متن کاملGenome-Wide Analysis of Microsatellite Markers Based on Sequenced Database in Chinese Spring Wheat (Triticum aestivum L.)
Microsatellites or simple sequence repeats (SSRs) are distributed across both prokaryotic and eukaryotic genomes and have been widely used for genetic studies and molecular marker-assisted breeding in crops. Though an ordered draft sequence of hexaploid bread wheat have been announced, the researches about systemic analysis of SSRs for wheat still have not been reported so far. In the present s...
متن کاملIdentification and characterization of genes on a single subgenome in the hexaploid wheat (Triticum aestivum L.) genotype 'Chinese Spring'.
Gene loss during the formation of hexaploid bread wheat has been repeatedly reported. However, our knowledge on genome-wide analysis of the genes present on a single subgenome (SSG) in bread wheat is still limited. In this study, by analysing the 'Chinese Spring' chromosome arm shotgun sequences together with high-confidence gene models, we detected 433 genes on a SSG. Greater gene loss was obs...
متن کاملMolecular and biochemical characterization of cytosolic phosphoglucomutase in wheat endosperm (Triticum aestivum L. cv. Axona).
Evidence from a number of plant tissues suggests that phosphoglucomutase (PGM) is present in both the cytosol and the plastid. The cytosolic and plastidic isoforms of PGM have been partially purified from wheat endosperm (Triticum aestivum L. cv. Axona). Both isoforms required glucose 1,6-bisphosphate for their activity with K(a) values of 4.5 micro M and 3.8 micro M for cytosolic and plastidic...
