1. Morphological and molecular studies on the Brazilian native red seaweed Laurencia oliveirana (Rhodomelaceae, Ceramiales)
Morphological and molecular studies were carried out on Laurencia oliveirana from the type locality (Arraial do Cabo, Rio de Janeiro, Brazil). This species is easily recognized by its small size, sub-erect habit forming intricate cushion-like tufts and unilateral pectinate branching. The species displays all the typical characters of the genus Laurencia, suc

2. Taxonomia das espécies sul-brasileiras de Calydorea Herbert (Iridaceae) e caracterização por DNA "Barcode"
This study aimed a taxonomic revision of the genus Calydorea from southern Brazil, providing the basis for identification of the species, by means of a dichotomous key, illustrations and images of plants in the natural environment. Another aim was to verify the effectiveness of use of target gene sequences to discriminate species, in the light of the propose

3. Diversidade do gênero Hypnea (Gigartinales, Rhodophyta) do estado de São Paulo baseada em marcadores moleculares e morfologia / Diversity of the genus Hypnea (Gigartinales, Rhodophyta) from São Paulo State, based on molecular markers and morphology
O gênero Hypnea J.V. Lamouroux (1813) (Cystocloniaceae, Gigartinales), com cerca de 67 espécies descritas, apresenta ampla distribuição geográfica pelas costas marinhas de águas quentes ao redor do mundo. Algumas espécies de Hypnea são usadas para a produção de carragenanas, hidrocolóides de grande importância na indústria atual. A taxonomia do

4. Sistemática molecular de espécies de Thorea (Rhodophyta, Thoreales) no Brasil
Este estudo objetivou avaliar a taxonomia no nível específico e as relações filogenéticas entre as espécies de Thorea do Brasil e de outras regiões do mundo usando dois marcadores moleculares - genes plastidial da subunidade grande da RUBISCO (rbcL) e nuclear da subunidade pequena do DNA ribossômico (SSU rDNA). Três amostras de Thorea do Brasil (Est

5. Morphological and molecular characterization of the cyanobacterial genus Anabaena isolated from Brazilian water bodies / Caracterização morfológica e molecular de cianobactérias do gênero Anabaena isoladas de corpos dágua brasileiros
Com o advento dos estudos moleculares evolutivos baseados nas sequências dos genes de RNAr 16S em cianobactérias, a taxonomia de Anabaena (Cyanobacteria) tem sido amplamente discutida e uma revisão deste gênero faz-se necessária. Os problemas variam desde o nível genérico, tal como o grupo Anabaena Aphanizomenon, até níveis de diferenciação de lin

6. Taxonomia, distribuição geográfica e filogenia do gênero Codium Stackhouse (Bryopsidales-Chlorophyta) no litoral brasileiro
Codium Stackhouse é um gênero exclusivamente marinho, engloba 125 táxons e encontra-se distribuído nos mares de quase todo o mundo, com exceção para as regiões polares. A maior diversidade infragenérica encontra-se nos mares da zona temperada e subtropical. No Brasil, são poucas as informações sobre o gênero, sendo que a maioria dos estudos refer

7. Activity of the Chlamydomonas chloroplast rbcL gene promoter is enhanced by a remote sequence element.
The chloroplast gene rbcL encodes the large subunit of ribulose bisphosphate carboxylase. In Chlamydomonas reinhardtii, this gene is transcribed more actively than any other protein-encoding chloroplast gene studied to date. To delineate the rbcL gene promoter, chimeric reporter genes containing fragments of the 5' region of the rbcL gene fused to the coding

8. Relocation of the plastid rbcL gene to the nucleus yields functional ribulose-1,5-bisphosphate carboxylase in tobacco chloroplasts.
The conserved plastid localization of rbcL suggests that biosynthesis of the large subunit of ribulose-1,5-bisphosphate carboxylase [Rubisco; 3-phospho-D-glycerate carboxy-lyase (dimerizing), EC 4.1.1.39] in chloroplasts is required to obtain functional enzyme. To examine the validity of this hypothesis, we relocated the plastid rbcL gene to the nucleus. Fir

9. 5' sequences are important positive and negative determinants of the longevity of Chlamydomonas chloroplast gene transcripts.
We have found that sequences in the 5' leader of the Chlamydomonas chloroplast rbcL gene, when fused 5' to foreign genes, destabilize transcripts of these chimeric genes in the chloroplast of transgenic Chlamydomonas but that 5' sequences of the rbcL structural gene prevent this destabilization. Transcripts of the chloroplast rbcL gene are about equally abun

10. Plastome Engineering of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase in Tobacco to Form a Sunflower Large Subunit and Tobacco Small Subunit Hybrid1
Targeted gene replacement in plastids was used to explore whether the rbcL gene that codes for the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase, the key enzyme of photosynthetic CO2 fixation, might be replaced with altered forms of the gene. Tobacco (Nicotiana tabacum) plants were transformed with plastid DNA that contained the rbcL

11. Amplification of the rbcL gene from dissolved and particulate DNA from aquatic environments.
The carboxylation of ribulose biphosphate by the enzyme ribulosebisphosphate carboxylase/oxygenase is the mechanism for CO2 fixation and primary production in nearly all ecosystems on this planet. Although certain algal isolates and higher plants contain conserved nucleotide sequences in the large subunit of the gene (rbcL) for this enzyme, such genes from n

12. Ribulose-1,5-bisphosphate carboxylase/oxygenase gene expression and diversity of Lake Erie planktonic microorganisms.
Carbon dioxide fixation is carried out primarily through the Calvin-Benson-Bassham reductive pentose phosphate cycle, in which ribulose-1, 5-bisphosphate carboxylase/oxygenase (RubisCO) is the key enzyme. The primary structure of the large subunit of form I RubisCO is well conserved; however, four distinct types, A, B, C, and D, may be distinguished, with ty
