Identification and mapping of expressed genes, simple sequence repeats and transposable elements in centromeric regions of rice chromosomes.
The genomic sequences derived from rice centromeric regions were analyzed to facilitate the comprehensive understanding of the rice genome. A rice centromere-specific satellite sequence, RCS2/TrsD/CentO, was used to screen P1-derived artificial chromosome (PAC) and bacterial artificial chromosome (BAC) genomic libraries derived from Oryza sativa L. ssp. japonica cultivar Nipponbare. Physical ma...
متن کاملNeocentrics and holokinetics (holocentrics): chromosomes out of the centromeric rules.
The centromere appears as a single constriction at mitotic metaphase in most eukaryotic chromosomes. Holokinetic chromosomes are the exception to this rule because they do not show any centromeric constrictions. Holokinetic chromosomes are usually forgotten in most reviews about centromeres, despite their presence in a number of animal and plant species. They are generally linked to very intrig...
متن کاملFORRepeats: detects repeats on entire chromosomes and between genomes
MOTIVATION As more and more whole genomes are available, there is a need for new methods to compare large sequences and transfer biological knowledge from annotated genomes to related new ones. BLAST is not suitable to compare multimegabase DNA sequences. MegaBLAST is designed to compare closely related large sequences. Some tools to detect repeats in large sequences have already been developed...
متن کاملBarley allele-specific amplicons useful for identifying wheat-barley recombinant chromosomes.
Barley (Hordeum vulgare L.) is potentially a new source of genes for wheat (Triticum aestivum L.) improvement. Wheat-barley chromosome recombinant lines provide a means for introgressing barley genes to wheat genome by chromosome engineering, and since these are expected to occur only rarely in special cytogenetic stocks, an efficient selection skill is necessary to identify them. To convert RF...
متن کاملBarley: From Brittle to Stable Harvest
Selection and domestication of plants with genes that prevent grains from shattering in cereals was essential for human civilization's transition to agriculture-based societies. In this issue, Pourkheirandish et al. show that domestication of barley required evolution of a molecular system distinct from other grains, such as rice and maize, and reveal that present-day cultivars derive from two ...
