Evolutionary History of LTR Retrotransposon Chromodomains in Plants
Chromodomain-containing LTR retrotransposons are one of the most successful groups of mobile elements in plant genomes. Previously, we demonstrated that two types of chromodomains (CHDs) are carried by plant LTR retrotransposons. Chromodomains from group I (CHD_I) were detected only in Tcn1-like LTR retrotransposons from nonseed plants such as mosses (including the model moss species Physcomitr...
متن کاملSkipper, an LTR retrotransposon of Dictyostelium.
The complete sequence of a retrotransposon from Dictyostelium discoideum , named skipper , was obtained from cDNA and genomic clones. The sequence of a nearly full-length skipper cDNA was similar to that of three other partially sequenced cDNAs. The corresponding retrotransposon is represented in approximately 15-20 copies and is abundantly transcribed. Skipper contains three open reading frame...
متن کاملFunctional and Structural Divergence of an Unusual LTR Retrotransposon Family in Plants
Retrotransposons with long terminal repeats (LTRs) more than 3 kb are not frequent in most eukaryotic genomes. Rice LTR retrotransposon, Retrosat2, has LTRs greater than 3.2 kb and two open reading frames (ORF): ORF1 encodes enzymes for retrotransposition whereas no function can be assigned to ORF0 as it is not found in any other organism. A variety of experimental and in silico approaches were...
متن کاملGene Deletion in Barley Mediated by LTR-retrotransposon BARE
A poly-row branched spike (prbs) barley mutant was obtained from soaking a two-rowed barley inflorescence in a solution of maize genomic DNA. Positional cloning and sequencing demonstrated that the prbs mutant resulted from a 28 kb deletion including the inflorescence architecture gene HvRA2. Sequence annotation revealed that the HvRA2 gene is flanked by two LTR (long terminal repeat) retrotran...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
