Genomic Clues to the Evolutionary Success of Polyploid Plants
Polyploidy, or the presence of two or more diploid parental genome sets within an organism, is found to an amazing degree in higher plants. In addition, many plant species traditionally considered to be diploid have recently been demonstrated to have undergone rounds of genome duplication in the past and are now referred to as paleopolyploids. Polyploidy and interspecific hybridisation (with wh...
متن کاملA Preliminary Note on Spirochætosis
|/ (1). Introduction. "The Arab Caravan brings bugs." A fact crudely recognised by the inhabitants of the many countries through which Arab traders travel, would lead one to expect that their mother country should prove no exception to the rule. Arabia, however, is a land where ticks swarm alone along its low lying fringe. In the high lands these acarids abound only along the big caravan routes...
متن کاملNovel patterns of gene expression in polyploid plants.
Genome doubling, or polyploidy, is a major factor accounting for duplicate genes found in most eukaryotic genomes. Polyploidy has considerable effects on duplicate gene expression, including silencing and up- or downregulation of one of the duplicated genes. These changes can arise with the onset of polyploidization or within several generations after polyploid formation and they can have epige...
متن کاملGenetic and epigenetic aspects of polyploid evolution in plants.
Polyploidy, the condition of possessing more than 2 complete chromosome sets in the same nucleus, is frequent in nature and has implications for a species' prospects for evolution. Newly formed polyploids, so-called neopolyploids, undergo a wide spectrum of genomic changes upon genome merger and duplication. Here, we review recent literature describing genomic and transcriptomic changes along t...
متن کاملeffects of first language on second language writing-a preliminary contrastive rhetoric study of farsi and english
to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...
