1. cDNA-AFLP analysis of gene expression differences between the flower bud and sprout-shoot apical meristem of Angelica sinensis (Oliv.) Diels
Angelica sinensis (Oliv.) Diels (Umbelliferae) is a well-known medicinal plant mainly distributed in Gansu Province of China. Its local and global demand is significant because of its food and medicinal applications. However, the early bolting rate of Angelica sinensis (Oliv.) Diels reaches 20%-60%, which seriously affects its food and medicinal qualities. T

2. EQUAÇÕES DE ESTIMATIVA DO CRESCIMENTO DO SISTEMA RADICULAR E PRODUÇÃO DE FITOMASSA DE ALFACE HIDROPÔNICA
Modelling is a technique that can be used to understand interactions between plant and environment, such as hydroponic growth dynamics. The study objective was to adjust models to estimate hydroponic lettuce growth, with emphasis on root system, the plants ware produced under different irrigations intervals. It was also verified the dynamics of interaction b

3. SELEÃÃO DE LINHAGENS DE ALFACE CRESPA PARA O VERÃO DERIVADAS DO CRUZAMENTO "SALINAS 88" x " VERÃNICA" COM TOLERÃNCIA AO LMV E A NEMATÃIDES
A necessidade de se produzir alface nas mais variadas regiÃes brasileiras, ao longo do ano, implica na exigÃncia do desenvolvimento de cultivares com menor suscetibilidade ao calor e resistÃncia a outros problemas comuns, como os nematÃides de galhas e o LMV. Objetivando selecionar quinze famÃlias F4 de alface do cruzamento âVerÃnicaâ x âSalinas 88�

4. Genetic variability and agronomic characterization of heat tolerant Lettuce Progenies. / Variabilidade genética e caracterização agronômica de progênies de alface tolerantes ao calor.
The objective of this work was to estimate the genetic variability and the correlations between agronomic characters in thirteen progenies F7 of lettuce, and in the genitors: Verdinha, Regina and Tinto, and in the cultivars Luisa and Baba de Verão. The experiment was conducted in Vitória de Santo Antão PE, in the period from September to December of 2005.

5. CaracterizaÃÃo de famÃlias de alface quanto à resistÃncia aos nematÃides das galhas (Meloidogyne spp.),tolerÃncia ao pendoamento precoce e caracterÃsticas comerciais / Characterization of lettuce breeding lines with relation to resistance to root knot nematodes (Meloidugyne spp.), tolerance to bolting and commercial traits
Lettuce yeids under higt temperature have been negatively affected by tendency to carly bolting and by root knot nematodes (Meloidogyne spp.) Resistante cultivars would be a sound alternative for cultivation inder these conditions.The present paper reports on the screening of new lettuce breending lines for tolerance to early bolting, resistance to root knot

6. 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

7. early bolting in short days: An Arabidopsis Mutation That Causes Early Flowering and Partially Suppresses the Floral Phenotype of leafy
The time of flowering in Arabidopsis is controlled by multiple endogenous and environmental signals. Some of these signals promote the onset of flowering, whereas others repress it. We describe here the isolation and characterization of two allelic mutations that cause early flowering and define a new locus, EARLY BOLTING IN SHORT DAYS (EBS). Acceleration of

8. Endogenous Gibberellins and Shoot Growth and Development in Brassica napus1
Greenhouse-grown oilseed rape (Brassica napus, annual Canola variety `Westar') plants were harvested at six dates from the vegetative phase until the early pod (silique)-fill/late flowering stage. Endogenous gibberellin (GA)-like substances were extracted from stems, purified, and chromatographed on silica gel partition columns prior to bioassay in serial di

9. 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

10. Mutagenesis of Plants Overexpressing CONSTANS Demonstrates Novel Interactions among Arabidopsis Flowering-Time Genes
CONSTANS (CO) promotes flowering of Arabidopsis in response to long photoperiods. Transgenic plants carrying CO fused with the cauliflower mosaic virus 35S promoter (35S::CO) flowered earlier than did the wild type and were almost completely insensitive to length of day. Genes required for CO to promote flowering were identified by screening for mutations th

11. Overexpression of a Novel Class of Gibberellin 2-Oxidases Decreases Gibberellin Levels and Creates Dwarf Plants
Degradation of active C19-gibberellins (GAs) by dioxygenases through 2β-hydroxylation yields inactive GA products. We identified two genes in Arabidopsis (AtGA2ox7 and AtGA2ox8), using an activation-tagging mutant screen, that encode 2β-hydroxylases. GA levels in both activation-tagged lines were reduced significantly, and the lines displayed dwarf phenoty
