1. Criptógamos do Parque Estadual das Fontes do Ipiranga, São Paulo, SP. Algas 36: Bacillariophyceae (Cymbellales)
Foi providenciado o levantamento florístico da ordem Cymbellales (Bacillariophyceae) na área do PEFI, Parque Estadual das Fontes do Ipiranga, São Paulo, SP, Brasil, com base na análise de 28 unidades amostrais. Amostras de plâncton foram obtidas com auxílio de rede e as de perifíton pela coleta e remoção das diatomáceas aderidas aos talos de macró

2. Transcriptome analysis of resistant soybean roots infected by Meloidogyne javanica
Soybean is an important crop for Brazilian agribusiness. However, many factors can limit its production, especially root-knot nematode infection. Studies on the mechanisms employed by the resistant soybean genotypes to prevent infection by these nematodes are of great interest for breeders. For these reasons, the aim of this work is to characterize the trans

3. Sobre a sinonímia de Stictocephala alta (Walker) e Thelia constans Walker (Hemiptera: Membracidae)
São abordadas a sinonímia de Ceresa alta Walker, 1851, atualmente Stictocephala alta, e de Thelia constans Walker, 1851, como seu sinônimo júnior. Comentários sobre Stictocephala bisonia Kopp & Yonke, 1977 são apresentados também.

4. 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

5. Dois sinônimos para Hadrophallus bubalus (Fabricius) (Hemiptera, Membracidae)
Dois sinônimos são considerados: Hadrophallus bubalus (Fabricius, 1794) = Ceresa integra Walker, 1858 syn. nov. = Ceresa borealis Fairmaire, 1846 syn. restaur. A espécie Spissistilus constans (Walker, 1851) sensu Caldwell, 1949 é considerada interpretação errônea de H. bubalus.

6. Identificação de etiquetas de seqüências expressas (ESTs) de Eucalytpus relacionadas a genes das vias controladoras do florescimento de Arabidopsis
As decisões envolvidas na iniciação do processo de florescimento dependem da expressão equilibrada de uma rede complexa de genes, que é regulada por fatores endógenos e ambientais. A regulação correta da transição para o florescimento é crucial para o sucesso reprodutivo das plantas; dessa forma elas desenvolveram mecanismos moleculares conservado

7. Control of photoperiod-regulated tuberization in potato by the Arabidopsis flowering-time gene CONSTANS
Photoperiod controls several responses throughout the plant life cycle, like germination, flowering, tuber formation, onset of bud dormancy, leaf abscission, and cambium activity. From these processes, flowering has been most extensively studied, especially in Arabidopsis thaliana. Photoperiod sensing by the function of photoreceptors and the circadian clock

8. CONSTANS Activates SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 through FLOWERING LOCUS T to Promote Flowering in Arabidopsis1[w]
CONSTANS (CO) regulates flowering time by positively regulating expression of two floral integrators, FLOWERING LOCUS T (FT) and SUPPRESSOR OF OVEREXPRESSION OF CO 1 (SOC1), in Arabidopsis (Arabidopsis thaliana). FT and SOC1 have been proposed to act in parallel pathways downstream of CO based on genetic analysis using weak ft alleles, since ft soc1 double m

9. Graft Transmission of a Floral Stimulant Derived from CONSTANS1
Photoperiod in plants is perceived by leaves and in many species influences the transition to reproductive growth through long-distance signaling. CONSTANS (CO) is implicated as a mediator between photoperiod perception and the transition to flowering in Arabidopsis. To test the role of CO in long-distance signaling, CO was expressed from a promoter specific

10. TERMINAL FLOWER2, an Arabidopsis Homolog of HETEROCHROMATIN PROTEIN1, Counteracts the Activation of FLOWERING LOCUS T by CONSTANS in the Vascular Tissues of Leaves to Regulate Flowering Time
The flowering time of plants is tightly regulated by both promotive and repressive factors. Molecular genetic studies using Arabidopsis have identified several epigenetic repressors that regulate flowering time. TERMINAL FLOWER2 (TFL2), which encodes a homolog of HETEROCHROMATIN PROTEIN1, represses FLOWERING LOCUS T (FT) expression, which is induced by the a

11. Hd1, a Major Photoperiod Sensitivity Quantitative Trait Locus in Rice, Is Closely Related to the Arabidopsis Flowering Time Gene CONSTANS
A major quantitative trait locus (QTL) controlling response to photoperiod, Hd1, was identified by means of a map-based cloning strategy. High-resolution mapping using 1505 segregants enabled us to define a genomic region of ∼12 kb as a candidate for Hd1. Further analysis revealed that the Hd1 QTL corresponds to a gene that is a homolog of CONSTANS in Arab

12. Antagonistic regulation of flowering-time gene SOC1 by CONSTANS and FLC via separate promoter motifs
Flowering in Arabidopsis is controlled by endogenous and environmental signals relayed by distinct genetic pathways. The MADS-box flowering-time gene SOC1 is regulated by several pathways and is proposed to co-ordinate responses to environmental signals. SOC1 is directly activated by CONSTANS (CO) in long photoperiods and is repressed by FLC, a component of
