1. Modelling evapotranspiration for reference crop and acid lime orchard based on regression and artificial neural network tecniques / Modelagem da evapotranspiração de referência e da evapotranspiração de limeira ácida com aplicação de técnicas de regressão e redes neurais artificiais
The main objective of this study was to test artificial neural networks (ANNs) of multilayer perceptron type (MLP) for estimating reference evapotranspiration, diffusive leaf conductance and crop evapotranspiration of a mature and irrigated citrus orchard. The ANNs were trained under conjugate gradient algorithm. The sigmoid and linear activation functions w

2. Caracterização fisiológica do mutante gun4 de Arabidopsis thaliana sob estresse luminoso / Physiological characterization of gun4 mutant of Arabidopsis thaliana under light stress
Mutações em genes denominados GUN (Genome UNcoupled) têm auxiliado na compreensão das rotas de transdução de sinais do cloroplasto que controlam a expressão de genes fotossintéticos nucleares. Nesse sentido, o genótipo gun4 tem sido caracterizado em aspectos bioquímicos e moleculares, no entanto pouco se sabe sobre aspectos fisiológicos desse muta

3. Fitomonitoração e modelagem de fotossíntese em jatobá (Hymenaea courbaril L.) com redes neurais artificiais. / Phytomonitoring and modelling of photosynthesis in jatobá (Hymenaea courbaril L.) with artificial neural.
The increases in greenhouse gas concentrations, mainly carbon dioxide, and the climatic changes have become important scientific, economic, and political subjects in the past years. The Kyoto Protocol establishes the Clean Development Mechanism, which grants carbon credits for projects that promote the sequestration of carbon in developing countries. Therefo

4. A possible evolutionary origin for the Mn4 cluster of the photosynthetic water oxidation complex from natural MnO2 precipitates in the early ocean
The photosynthetic water oxidation complex consists of a cluster of four Mn atoms bridged by O atoms, associated with Ca2+ and Cl−, and incorporated into protein. The structure is similar in higher plants and algae, as well as in cyanobacteria of more ancient lineage, dating back more than 2.5 billion years ago on Earth. It has been proposed that the proto

5. Elucidation of Gene Interaction Networks Through Time-Lagged Correlation Analysis of Transcriptional Data
The photosynthetic cyanobacterium Synechocystis sp. strain PCC 6803 uses a complex genetic program to control its physiological response to alternating light conditions. To study this regulatory program time-series experiments were conducted by exposing Synechocystis sp. to serial perturbations in light intensity. In each experiment whole-genome DNA microarr

6. Contrapuntal Networks of Gene Expression during Arabidopsis Seed FillingW⃞
We have used cDNA microarrays to examine changes in gene expression during Arabidopsis seed development and to compare wild-type and mutant wrinkled1 (wri1) seeds that have an 80% reduction in oil. Between 5 and 13 days after flowering, a period preceding and including the major accumulation of storage oils and proteins, ∼35% of the genes represented on th
