We introduce the software tool NTRFinder to search for a complex repetitive structure in DNA we call a nested tandem repeat (NTR). An NTR is a recurrence of two or more distinct tandem motifs interspersed with each other. We propose that NTRs can be used as phylogenetic and population markers. We have tested our algorithm on both real and simulated data, and present some real NTRs of interest. ...

Molecular sequences provide a rich source of data for inferring the phylogenetic relationships among species. However, recent work indicates that even an accurate multiple alignment of a large sequence set may yield an incorrect phylogeny and that the quality of the phylogenetic tree improves when the input consists only of the highly conserved, motif regions of the alignment. This work introdu...

A comparative molecular study of Aperigiullus protease using sequence gene representative 25 different Aspergillus species (Aspergillus fumigatus, oryzae, flavus, novofumigatus, viridinutans, pseudotamarii, clavatus, sojae, fischeri, caelatus, campestris, costaricaensis, candidus, neoniger, mulundensis, ibericus, niger, piperis, eucalypticola, vadensis, steynii, and lentulus) have been describe...

Aim. To identify the genes of false flax (Camelina sativa) endogenous lipases and to analyze sequence similarity their key functional domains with those commercially available lipases. Methods. A detailed search databases was carried out in order sequences various species, as well were aligned, conservative motifs identified, domain structure detected proteins established, phylogenetic analysis...

Our group has developed a series of iron-based asymmetric transfer hydrogenation (ATH) catalysts for the reduction of polar double bonds. The activation of the precatalysts as well as the catalytic mechanism have been thoroughly investigated, but the decomposition pathways of these systems are poorly understood. Herein, we report a study of the deactivation pathways for an iron ATH catalyst und...

Fluctuations in population size are in many cases undesirable, as they can induce outbreaks and extinctions or impede the optimal management of populations. We propose the strategy of adaptive threshold harvesting (ATH) to control fluctuations in population size. In this strategy, the population is harvested whenever population size has grown beyond a certain proportion in comparison to the pre...

The WD40 transcription factor family is a superfamily found in eukaryotes and implicated regulating growth development. In this study, 167 genes are identified the Ginkgo biloba genome. They divided into 5 clusters 16 subfamilies based on difference analysis of phylogenetic tree domain structures. distribution chromosomes, gene structures, motifs analyzed. Promoter shows that five GbWD40 promot...
