1. RNA editing in the chloroplast of Asian Palmyra palm (Borassus flabellifer)
Abstract We have identified 46 RNA editing sites located in 20 chloroplast (cp) genes of Borassus flabellifer (Asian Palmyra palm), family Arecaceae, and tested these genes for supporting phylogenetic study among the commelinids. Among the 46 sites, 43 sites were found to cause amino acid alterations, which were predicted to increase the hydrophobicity and t

2. pGVG: a new Gateway-compatible vector for transformation of sugarcane and other monocot crops
Abstract The successful development of genetically engineered monocots using Agrobacterium-mediated transformation has created an increasing demand for compatible vectors. We have developed a new expression vector, pGVG, for efficient transformation and expression of different constructs for gene overexpression and silencing in sugarcane. The pCAMBIA2300 bin

3. Elaiophores: their taxonomic distribution, morphology and functions
ABSTRACT Elaiophores are floral glands that secrete non-volatile oils as a reward for their pollinators. Their secretions mediate a specialized interaction between oil-producing plants and a few species of oil-collecting bees - Apidae and Melittidae. The present review focuses on the morphological and functional aspects of these secretory structures. We also

4. Overview of the systematics and diversity of Poales in the Neotropics with emphasis on the Brazilian flora
Abstract Poales represents a major part of Angiosperm and Monocot diversity. The families encompass ca. 20,000 species which is about 7% of the Angiosperms and 33% of the Monocots. Bromeliaceae, Cyperaceae, Eriocaulaceae, Juncaceae, Mayacaceae, Poaceae, Rapateaceae, Thurniaceae, Typhaceae, and Xyridaceae are the families represented in the Neotropics. In gen

5. Molecular characteristics, recombinant expression and activity detection of OsGSTL1 from rice
The mRNA of OsGSTL1 was detected in the roots and leaves of rice plants at seedling and tillering stages, and their roots, leaves and panicles at the heading stage. The full-length open reading frame of OsGSTL1 cDNA was 732 bp and encoded a putative polypeptide of 243 amino acids with a calculated molecular mass of 27.30 kDa and a theoretical pI of 5.50. The

6. Genome-wide identification and phylogenetic analysis of the ERF gene family in cucumbers
Members of the ERF transcription-factor family participate in a number of biological processes, viz., responses to hormones, adaptation to biotic and abiotic stress, metabolism regulation, beneficial symbiotic interactions, cell differentiation and developmental processes. So far, no tissue-expression profile of any cucumber ERF protein has been reported in

7. Análise da via de regulação gênica do miRNA156/SPL na brotação lateral e caracterização molecular do processo de emergência da gema axilar de cana de açucar / Analysis of the role(s) of the miRNA156/SPL pathway on branching/tillering and molecular characterization of sugarcane lateral bud outgrowth
Sugarcane is an economically important biofuel crop that recently has become a target for improvement of sustainable biomaterial production due to its high biomass productivity and built-in containment features. Therefore, studies aiming to improve the production of biomass per area are among the most important issues in sugarcane production. Plant biomass i

8. Comparative karyotypic analysis in the Alstroemeria hookeri Lodd. (Alstroemeriaceae) complex sensu Bayer (1987)
Alstroemeria L. (Alstroemeriaceae) is an American genus of monocots with two principal distribution centers in Chile and Brazil. In Chile, it is represented by about 32 species, most of them in central Chile, an area known for its high level of endemism. The "complex" Alstroemeria hookeri is endemic to Chile, where it is distributed from the Coquimbo to the

9. Monocotiledôneas terrícolas em um fragmento de Floresta Ombrófila Densa no Litoral Norte do Rio Grande do Sul
(Monocotiledôneas terrícolas em um fragmento de Floresta Ombrófila Densa no Litoral Norte do Rio Grande do Sul). As monocotiledôneas são um grupo muito importante na estrutura da Floresta Ombrófila Densa sendo, no entanto, pouco estudadas, principalmente as plantas terrícolas. Em um fragmento no Litoral Norte do Rio Grande do Sul (29o23’S e 49o50’

10. Identificação de micro RNAs em cana-de-açucar / Towards the identification of the sugarcane microRNAs
No-coding RNAs of 20-27 nucleotides (nt) transcriptional or posttranscriptionally regulate endogenous gene expression, affecting the cellular output of transcripts and proteins. Among these RNAs, microRNAs (miRNAs) play an important role in plant development as confirmed by phenotypic and molecular evaluation of transgenic plants and knockout mutants defecti

11. Caracterização de dois cDNAs homológos e uma AP endonuclease em cana-de-açúcar
The genome of all organisms is subject to injuries that can be caused by endogenous and environmental factors. If these lesions are not corrected, it can be fixed generating a mutation which can be lethal to the organisms. In order to prevent this, there are different DNA repair mechanisms. These mechanisms are well known in bacteria, yeast, human, but not i
