R2R3-MYB TFs represent one of the most extensive gene families in plants and play a crucial role regulating plant development, metabolite accumulation, defense responses. Nevertheless, there has been no systematic investigation into pomegranate family. In this study, 186 genes were identified from genome grouped 34 subgroups based on phylogenetic analysis. Gene structure analysis showed that Pg...

in this work, we investigate the transfer of some homological properties from a ring $r$ to its amalgamated duplication along some ideal $i$ of $r$ $rbowtie i$, and then generate new and original families of rings with these properties.

Vector geographic data play an important role in the natural resources and environment sector as well other location information services. This is also one of types where cost to create it relatively large because difficulty surveying, collecting, authorizing. The rapid development Internet has created many advantages distribution, exploitation, use vector data, but gives rise problems such dup...

Abs t r ac t . We consider a restricted variant of the prefix-sufñx duplication operation, called bounded prefix-sufñx duplication. It consists in the iterative duplication of a prefix or suffix, whose length is bounded by a constant, of a given word. We give a sufncient condition for the closure under bounded prefix-sufñx duplication of a class of languages. Consequently, the class of regular ...

We present a novel approach to deal with the problem of reconstructing the duplication history of tandemly repeated genes that are supposed to have arisen from unequal recombination. We first describe the mathematical model of evolution by tandem duplication and introduce duplication histories and duplication trees. We then provide a simple recursive algorithm which determines whether or not a ...
