ENGLISH ABSTRACT: Biopolymers exhibit the required material properties to replace conventional, non-biodegradable, petroleum-based polymer products. They have a closed carbon cycle, making them carbon neutral and environmentally friendly. Biopolymers are produced from non-toxic substrates during in vivo enzymatic reactions. Biosynthesis of the most commercially important biopolymers is too complex to be reproduced in in vitro reactions. Identification of the genes responsible for their biosynthesis has been under investigation, with some pathways already elucidated. The genes involved in the biosynthesis of these polymers have been targeted for genetic manipulation to increase productivity, as well as create tailor-made polymers. Novel biopolymers and the genes responsible for their synthesis are of interest for their potential commercial applications. Bacteria produce a wide range of biopolymers and are being implemented as the bio-factories for biopolymer production. They are capable of utilising easily accessible and renewable carbon sources such as sucrose for polymer biosynthesis. Bacteria thus allow for economical production of these environmentally beneficial polymers. In this study, the gene responsible for the production of an unknown biopolymer from an unknown bacterium was identified. The biopolymer producing bacteria were grown on media enriched with sucrose as carbon source, during an expression library screening in a previous study. Expression library technology was used to search for the gene and it was identified as a 424 amino acid levansucrase which had a 100% homology to Leuconostoc mesenteroides M1FT levansucrase (AAT81165.1). Biopolymer analysis revealed that the biopolymer was a levan, a polysaccharide consisting of only fructose molecules with a molecular weight of ± 5 kDa. Analysis of a 516 bp fragment of the 16S rRNA determined that the unknown bacteria were a Pseudomonas species.
AFRIKAANSE OPSOMMING: Bio-polimere besit noodsaaklike materiële eienskappe wat toelaat dat dit konvensionele, nie bio-afbreekbare, petroleum-gebasseerde polimeer produkte kan vervang. Hulle het n geslote koolstof kringloop en is dus koolstof neutraal en omgewingsvriendelik. Bio-polimere word vervaardig van nie-toksiese substrate, gedurende ensiematiese reaksies in vivo. Die belangrikste kommersiële bio-polimere se ensiematiese produksie is te kompleks om in ʼn in vitro reaksie te herproduseer. Ondersoeke tot die identifikasie van die gene wat verantwoordelik is vir die produksie van die polimere is onderweg, en sommige produksie paaie is reeds bekend. Die bekende gene word geteiken vir genetiese manipulasie om hulle produktiwiteit te vermeerder en om unieke polimere te produseer. Unieke bio-polimere en die gene wat vir hul produksie verantwoordelik is, is van belang vir hulle potentiële implimentering in komersiële toepassings. Bakteria produseer ʼn verskeidenheid bio-polimere en word as die bio-fabrieke vir polimeerproduksie geimplimenteer. Hulle kan maklik bekombare koolstofbronne, soos sukrose, gebruik om bio-polimere te produseer. Bakteria laat dus die ekonomiese produksie van hierdie omgewingsvriendelike polimere toe. In hierdie studie word die geen wat verantwoordelik is vir die produksie van ʼn onbekende bio-polimeer van ʼn onbekende bakteria, geidentifiseer. Die bakteria was gevind op media, wat verryk was met sukrose as koolstofbron, tydens ʼn vorige studie, waartydens ʼn uitdrukkingsbiblioteek gesif was op hierdie media. Uitdrukkingsbiblioteek tegnologie was gebruik om die geen te vind. Die geen was geidentifiseer as ʼn 424 aminosuur, homo-fruktose-polimeer produseerende geen, ʼn “levansucrase”. Die geen het ʼn 100% homologie met die M1FT “levansucrase” geen (AAT81165.1) van Leuconostoc mesenteroides gehad. Analise van die bio-polimeer het bepaal dat die polimeer ʼn polisakkaried was, wat slegs uit fruktose molekules bestaan het. Die molekulêre gewig van die polimeer was ± 5 kDa. Analise van ʼn 516 bp fragment van die 16S rRNS het bepaal dat die bakteria van die Pseudomonas spesie afkomstig was.

Résumé :
In the course of work aimed at discovering new sigma transcription initiation factors in Escherichia coli, two unknown sigma cross-reacting proteins (SCRP-23 and SCRP-27A) were identified by cross-reaction with antibodies raised against region 2.2 of sigma 70. This thesis describes the mapping, sequencing and characterisation of the corresponding genes. The gene encoding SCRP-23 was located near 652kb on the physical map of the E. coli chromosomes. Its sequence and that of part of a downstream open reading frame were determined, and found to be closely similar to the ahpC and F genes (respectively) of Salmonella typhimurium. These encode the C22 and F52a subunits of the anti-oxidant enzyme, alkylhydroperoxide reductase. The identity of the E. coli genes was further established by their ability when introduced on plasmids into an ahp deletion strain to restore cumene hydroperoxide resistance. Transcription of ahpCF was found to be driven by two promoters: ahpP1 is dependent on activation by the OxyR transcriptional regulator, whilst ahpP2 is independent of this factor. Indeed ahpP2 is located within the OxyR target site, and is repressed when OxyR is activated by oxidation. The gene encoding SCRP-27A, scrP, was located near 3416 kb on the physical map, just 250 bp downstream of arcB. arcB encodes a transmembrane sensor-regulator of respiratory functions.

Résumé :
In order to identify Leishmania proteins which may be immunologically relevant or may play a role in interactions between Leishmania and its mammalian host, a Leishmania major genomic DNA library was constructed in the vector λgt11 and screened with antibodies raised to Leishmania major promastigote membranes. Two recombinant DNA clones were identified which encoded repetitive sequences (Clone 20 and Clone 39). Clone 20 encoded a repetitive peptide of 14 amino acids and clone 39 encoded an unrelated repetitive peptide of 10 amino acids. Analysis of one of these clones, Clone 20, indicated that there were two RNA transcripts of 9500 and 5200 nucleotides expressed which corresponded to this clone in Leishmania major and Leishmania donovani and this expression was not stage-specific. The results of genomic DNA analysis and isolation of additional clones encoding Clone 20 sequences indicated that there were two genes which corresponded to Clone 20 in both Leishmania major and Leishmania donovani and that these genes differed from one another with respect to the number of repeats which they contained. Antibodies against the fusion protein produced by Clone 20 recognized a series of Leishmania major proteins of apparent mol wt 250,000. Analysis of Clone 39 indicated that there was a single transcript of 7500 nucleotides expressed which corresponded to this clone in both Leishmania major and Leishmania donovani and that there was a single gene (or two identical genes) which encoded this transcript. The genomes of many protozoan parasites exhibit a high degree of plasticity with respect to chromosome size and number. The presence of highly repetitive regions within their DNA may be involved in maintaining this plasticity, allowing the parasite to evolve rapidly under selective pressure. Repetitive regions have been identified within many Plasmodia antigens and have been implicated in the ability of this parasite to evade the host immune system. The presence of Leishmania genes encoding proteins containing tandemly repeating peptides may indicate that these proteins play a similar role in evading the host immune system during the course of Leishmania infections. The possible evolution and functions of repetitive proteins in protozoan parasites is discussed.

Texte intégral
Résumé :
Normal human color vision is usually thought to be based on only three spectrally different cone types. However, two facts suggest the possibility that some color-normal males could have more than three cone pigment types: (1) Most people with normal color vision have more than two photopigment genes on each X-chromosome and (2) there appear to be genetically specified variations in spectral positions of the normal middle-wavelength-sensitive (MWS) and long-wavelength-sensitive (LWS) pigments. For example, a male might have one gene encoding an LWS pigment and two genes encoding slightly different MWS pigments. If all three different X-encoded genes were expressed in different cones, then this person would have four spectrally different cone types. How firm is the assumption that more than two of the X-encoded pigment genes can be expressed? Both analysis of the statistics of photopigment gene number among different color vision phenotypes and analysis of the arrangement of pigment genes on the X-chromosome yield insight into this aspect of photopigment gene expression. These analyses suggest that individuals with multiple pigment genes on the X-chromosome may express more than two of those genes.

Résumé :
Genes encoding cone pigments sensitive to middle-to-long wavelengths lie in a head-to-tail tandem array on the X-chromosome. Although two X-encoded genes, one for long-wavelength-sensitive pigments and one for middle-wavelength-sensitive pigments, are sufficient to serve trichromatic color vision, most people have more than two such genes. The arrangement, location, and degree of homology of the pigment genes promote recombination within the tandem arrays. Such recombination events produce pigment-gene complements that differ in the number and sequences of individual genes and in the interrelationships between genes. The accumulation of recombination-generated changes over the span of evolutionary time has culminated in a large number of X-encoded photopigment gene complements in the human population. It is, thus, not surprising that there are widespread variations in human color vision.

Texte intégral
Résumé :
Background: Gliomas are classified based from the molecular parameters involved in their pathogenesis, which influence their prognosis. The parameters are based on the mutation of the genes encoding the enzyme isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2), on the codelection of the arms of chromosome 1p/19q and the promoting hypermethylation of the MGMT gene. Objectives: identify tumor markers related to gliomas and their prognostic values. Methods: integrative review of the literature based on pubmed, lilacs and scielo platforms. Articles published in English, Portuguese and Spanish between 2016 and 2021 were included. Articles that were not related to the theme were excluded from the analysis. Results: The IDH1 and 2 genes are traditional markers and mutations in these genes are associated with a better prognosis. The codeletion 1p/19q, on the other hand, is indicative of a more favorable prognosis when related to tumors without codeletion. MGMT gene hypermethylation has strong prognostic value in patients treated with radiotherapy and chemotherapy with alkyl agentes, because the low expression of the MGMT gene allows better efficacy of the therapy, which would be prevented by the MGMT enzyme. The circulating marker microRNA – 221 (miRNA), obtained by less invasive techniques, is an indicator of poor prognosis, however, it has not yet obtained clinical validation for use. Conclusion: It is concluded that the tumor markers that indicate a better prognosis are the genes IDH-I and II, the codelection 1p / 19q and the hypermethylation of the MGMT gene. While miRNA showed a worse prognosis.

Résumé :
A violation of the hormonal balance is considered one of the factors affecting the development of osteoporosis (OP). The study of the molecular and genetic aspects of this fact will allow us to select a more effective course of OP therapy in the future. Sex hormones, as activators of the expression of a number of genes that regulate bone metabolism, act indirectly through specific receptors. We considered polymorphic variants of the estrogen receptor genes ESR1 and ESR2, encoding the a and в subunits of the estrogen receptor, respectively. Among the studied polymorphic variants of ESR1 (rs9340799, rs2234693, rs1801132) and ESR2 (rs3020444), we identified an association of the T/T genotype of the ESR1 (PvuII) rs2234693 gene with the risk of developing OP (p=0.026) in the Belarusian population.

Résumé :
Stress-associated proteins (SAP) in many plants are involved in the response to adverse factors of biotic and abiotic nature. In order to study changes in the expression level of SAP genes in apple trees, MM-106 rootstocks were exposed to drought for 24 h. Expression profiles of 14 studied genes encoding SAP were established during the quantitative PCR reaction (qPCR), among which wererevealed of actively expressed under specified conditions. The majority of SAP genes have maximum transcript accumulation by 4 hours of exposure to drought.

Résumé :
In this research we have studied the molecular biology of carotenoid biosynthesis in tomato. The investigations focused on the genes Pds and Psy, encoding desaturase and phytoene synthase, respectively, which are key enzymes in the biosynthetic pathway of lycopene and b-carotene. In addition, we have investigated the genes for lycopene cyclase. We have cloned from tomato and characterized the cDNA of CrtL-e, which encodes the lycopene e-cyclase, and analyzed its expression during fruit development. The results establish a paradigm for the regulation of carotenoid pigment biosynthesis during the ripening process of fruits. It is concluded that transcriptional regulation of genes that encode carotenoid-biosynthesis enzymes is the major mechanism that governs specific pigment accumulation. During the ripening of tomato fruits transcription of the genes encoding the enzymes phytoene synthase and phytoene desaturase is up-regulated, while the transcription of the genes for both lycopene cyclases decreases and thus the conversion of lycopene to subsequent carotenoids is inhibited. These findings support the working hypothesis of the molecular approach to manipulating carotenogenesis by altering gene expression in transgenic plants, and offer obvious strategies to future application in agriculture. The molecular and physiological knowledge on carotenogenesis gained in this project, suggest a concept for manipulating gene expression that will alter carotenoid composition in fruits and flowers.

Texte intégral
Résumé :
The ability of flowering plants to prosper throughout evolution, and for many crop plants to set fruit, is strongly dependent on their ability to attract pollinators. To that end many plants synthesize a spectrum of volatile compounds in their flowers. Scent is a highly dynamic trait that is strongly influenced by the environment. However, with high temperature conditions becoming more common, the molecular interplay between this type of stress and scent biosynthesis need to be investigated. Using petunia as a model system, our project had three objectives: (1) Determine the expression patterns of genes encoding biosynthetic scent genes (BSGs) and of several genes previously identified as encoding transcription factors involved in scent regulation under normal and elevated temperature conditions. (2) Examine the function of petunia transcription factors and a heterologous transcription factor, PAPl, in regulating genes of the phenylpropanoid/benzenoid scent pathway. (3) Study the mechanism of transcriptional regulation by several petunia transcription factors and PAPl of scent genes under normal and elevated temperature conditions by examining the interactions between these transcription factors and the promoters of target genes. Our work accomplished the first two goals but was unable to complete the third goal because of lack of time and resources. Our general finding was that when plants grew at higher temperatures (28C day/22C night, vs. 22C/16C), their scent emission decreased in general, with the exception of a few volatiles such as vanillin. To understand why, we looked at gene transcription levels, and saw that generally there was a good correlation between levels of transcriptions of gene specifying enzymes for specific scent compounds and levels of emission of the corresponding scent compounds. Enzyme activity levels, however, showed little difference between plants growing at different temperature regimes. Plants expressing the heterologous gene PAPl showed general increase in scent emission in control temperature conditions but emission decreased at the higher temperature conditions, as seen for control plants. Finally, expression of several transcription factor genes decreased at high temperature, but expression of new transcription factor, EOB-V, increased, implicating it in the decrease of transcription of BSGs. The major conclusion of this work is that high temperature conditions negatively affect scent emission from plants, but that some genetic engineering approaches could ameliorate this problem.
