Varieties and Clones of Relational Structures
We present an axiomatization of relational varieties, i.e., classes of relational structures closed under formation of products and retracts, by a certain class of first-order sentences. We apply this result to categorically equivalent algebras and primal algebras. We consider the relational …

Expression and Biochemical Function of Putative Flavonoid GT Clones from Grapefruit and Identification of New Clones using the harvEST Database.
… test the hypothesis that additional putative GT clones could be identified using the harvEST database.</p>

MITO: ROBUST INFERENCE OF MITOCHONDRIAL PHYLOGENIES AND CLONES
… multiple sub-clonal lineages within individual clones participate to the metastatic dissemination in Breast Cancer xenografts, implying stronger lineage-dependency of the metastatic phenotype in Breast Cancer that previously thought. In summary, this work highlights opportunities and limitations …

Quantitative analyses to study tumor clones dynamics and tumor heterogeneity
Prostate cancer is a highly heterogeneous disease and its manifestations can vary from indolent localized tumor to widespread metastases. This heterogeneity is also observed at the molecular level both inter- and intra-patient. Intra-patient heterogeneity in the clinical setting of men with …

On the Stability of Software Clones: A Genealogy-Based Empirical Study
Clones are a matter of great concern to the software engineering community because of their dual but contradictory impact on software maintenance. While there is strong empirical evidence of the harmful impact of clones on maintenance, a number of studies have also identified positive sides of code …

Transcriptional responses of Eucalyptus clones to the gall wasp, Leptocybe invasa
Eucalyptus species constitute some of the most widely grown and economically important hardwood trees in global plantation forestry. This is due primarily to their remarkable growth and adaptability. Much of the initial success of exotic Eucalyptus plantations was attributed to the separation from …

Your Self Again: Clones, Originals, and True Selves of Science Fiction
This is a practice-led research project, exploring ideas of personal identity in the light of human cloning in science fiction (SF). Its main aim is to understand how SF writers can benefit from theories of identity and characterisation to develop fictional characters in clone narratives. The …

Enxertia in vitro de clones de Eucalyptus urophylla x E. grandis
… da enxertia in vitro na propagação de dois clones de Eucalyptus urophylla x E. grandis. Foram utilizados porta-enxertos juvenis obtidos de sementes de Eucalyptus urophylla e E. grandis, germinadas em condições assépticas. As avaliações foram realizadas quanto ao percentual de pegamento e …

Prevalence and fate of pro-oncogenic clones in the human colon
… number of patients and crypts, pro-oncogenic clones were detected for eight colorectal cancer driver genes; ARID1A, APC, CTNNB1, FBXW7, KRAS, PTEN, TP53 and SMAD4. Losses or gain of function in these genes were associated with biases in the processes of clone fixation and expansion, which …

Response of Leaf Protein to Ozone in Two White Clover Clones
… the vegetative biomass ratio (NC-S/NC-R) of the clones was correlated with increasing concentrations of ozone during a 28-day exposure period. However, the mechanism of ozone sensitivity or tolerance at the biochemical or molecular level is not known. Superoxide dismutase isozyme activities in …

Molecular diagnostics, genetic diversity and generating infectious clones for cassava brown streak viruses
… were carried out for generating infectious clones of CBSV; gateway cloning, in vivo and in vitro transcription methods, and amplification of the viral genome in three fragments. Although 3 overlapping CBSV fragments were successfully cloned, the presence of an unexpected mutation at one of …

An investigation into the sapstaining intrinsic properties of selected rubberwood (Hevea brasiliensis) clones
… of tolerance of sapstain fungi. New rubberwood clones have been recommended for planting since 1967. It is therefore timely to examine clonal differences in sapstaining properties of rubberwood clones. The purpose of this study was to investigate the intrinsic properties of 3 selected rubberwood …

Characterization of XV7 and XV9 cDNA clones which confer osmotolerance to Eschericia coli
The sequence similarity between XV7 and the mammalian syntaxin-like protein kinase receptor shows that XV7 may function similar to that of animal protein kinases. The syntaxin-like protein kinase receptor was recently entered into the Genbank (Thoreau, unpublished), therefore not much is known …

Growth, water use efficiency and stable carbon isotopes in commercial clones of Eucalyptus
… growth and water use efficiency of 6 commercial clones of Eucalyptus commonly grown in South Africa with the aim of determining the following: (i) The extent of clonal variation in growth, dry mass allocation patterns, water use efficiency and the water cost of wood production at 16 months after …

Isolation and analysis of cotton genomic clones encompassing a fatty acid desaturase (FAD2) gene
… gene was found to be in two overlapping genomic clones by physical mapping and DNA sequencing. The cloned DNA fragments are identical in size to cotton FAD2 genomic DNA fragments shown by genomic blot hybridization. The cotton FAD2 coding region has 1,155 bp with no introns and would encode a …
