1. Application of artificial neural networks in indirect selection: a case study on the breeding of lettuce
The efficiency of artificial neural networks (ANN) to model complex problems may enable the prediction of characteristics that are hard to measure, providing better results than the traditional indirect selection. Thus, this study aimed to investigate the potential of using artificial neural networks (ANN) for indirect selection against early flowering in le

2. Caracterização funcional de dois cDNAs de cana-de- açúcar : PKCI e SHAGGY
A floração é controlada por diversos fatores como condições ambientais e fatores endógenos que se associam em uma rede de mecanismos bastante complexos. A caracterização funcional de alguns genes realizada no modelo vegetal A. thaliana tem fornecido muitas informações a respeito dos mecanismos genéticos e bioquímicos que controlam a floração. E

3. Modelagem matemática na previsão de colheita de bananeira: regressão linear múltipla x redes neurais artificiais / Mathematical modeling to predict crop of banana: multiple regression x neural networks
One of the barriers relevant to the banana crop in Brazil is the lack of productive commercial varieties with adequate size, resistant to major pests and diseases and adapted to different ecosystems. The development of cultivars is the strategy for solving this problem through breeding programs, as well as its characterization and evaluation in areas of prod

4. Identification and partial characterization of SEPALLATA genes in coffee arabica / IdentificaÃÃo e caracterizaÃÃo parcial de genes SEPALLATA em cafà arÃbica
Coffee is one of the most important international commodity, produced in more than sixty countries and it is classified as one of the five agricultural exportation most valued in development countries. One of the biggest difficulties in this crop is the heterogeneity of the flowering process, therefore, imbalance on the fruit maturation, which makes the harv

5. História natural e interação flores-besouros em espécies de Cerrado / Natural history and flower-beetle interactions in Cerrado species
Plant-animal interactions, such as pollination, are a key element in many terrestrial communities. The study of who interacts with whom is an important approach for understanding ecological and evolutionary processes. In some tropical communities, up to one quarter of all plant species may be pollinated by beetles. They are an ancient and much diversified in

6. Polinizadores da aceroleira (Malpighia emarginata DC., Malpighiaceae) em área do Triângulo Mineiro : riqueza de espécies, nicho trófico, conservação e manejo / West Indian Cherrys (Malpighia emarginata DC., Malpighiaceae) pollinators in an area of Triângulo Mineiro: species richness, trophic niche, conservation and management
Bees are considered the most important pollinators of native plants and crops. In some cultures, they can increase the production and the fruit quality. Thus, studies that address issues of pollinators conservation and management like populations monitoring and knowledge about trophic resources are crucial. In this work, we present parameters that can suppor

7. A comunidade de esfingídeos (Lepidoptera, Sphingidae) e plantas esfingófilas numa área de cerrado no sudeste do Brasil: biogeografia e associações mutualísticas / The hawkmoth (Lepidoptera, Sphingidae) and hawkmoth-flower plant community in a Cerrado area of southeastern Brazil: biogeography and mutualistic associations
Hawkmoths (Lepidoptera, Sphingidae) are among the major pollinators in tropical communities. However, in the Cerrado biome little is known about their distribution, species composition, diversity, as well as, their relationships with hawkmoth-flower plant flora. This study aim to describe the hawkmoth fauna and hawkmoth-pollinated plant flora of a Cerrado ar

8. A genetic framework for flowering-time pathways in Citrus spp.
Floral transition is one the most drastic changes occurring during the life cycle of a plant. The shoot apical meristem switches from the production of leaves with associated secondary shoot meristems to the production of flower meristems. This transition is abrupt and generally irreversible, suggesting it is regulated by a robust gene regulatory network cap

9. Induction of flowering by seasonal changes in photoperiod
In many plants, major developmental transitions such as the initiation of flowering are synchronized to the changing seasons. Day length provides one of the environmental cues used to achieve this. We describe the molecular mechanisms that measure day length and control flowering in Arabidopsis. Also, we compare these mechanisms with those that control flowe

10. Ehd1, a B-type response regulator in rice, confers short-day promotion of flowering and controls FT-like gene expression independently of Hd1
Two evolutionarily distant plant species, rice (Oryza sativa L.), a short-day (SD) plant, and Arabidopsis thaliana, a long-day plant, share a conserved genetic network controlling photoperiodic flowering. The orthologous floral regulators—rice Heading date 1 (Hd1) and Arabidopsis CONSTANS (CO)—integrate circadian clock and external light signals into mRN

11. EARLY BOLTING IN SHORT DAYS Is Related to Chromatin Remodeling Factors and Regulates Flowering in Arabidopsis by Repressing FT
The timing of flowering initiation depends on the balanced expression of a complex network of genes that are regulated by both endogenous and environmental factors. We showed previously that mutations at the EARLY BOLTING IN SHORT DAYS (EBS) locus of Arabidopsis result in an acceleration of flowering, especially in noninductive photoperiods (short days), and

12. Extensive Phenotypic Variation in Early Flowering Mutants of Arabidopsis1
Flowering time, the major regulatory transition of plant sequential development, is modulated by multiple endogenous and environmental factors. By phenotypic profiling of 80 early flowering mutants of Arabidopsis, we examine how mutational reduction of floral repression is associated with changes in phenotypic plasticity and stability. Flowering time measure
