1. Cotton response to mepiquat chloride and temperature
Gibberellin inhibitor growth regulators are used for cotton (Gossypium hirsutum L.) canopy manipulation to avoid excess growth and yield losses. However, under temperatures below or over the optimum for cotton production the effect of mepiquat chloride (MC) has not always been significant. In this experiment, cotton plants were grown in growth chambers to st

2. Uso do regulador de crescimento daminozide no cultivo de pimenta (Capsicum annuum L.) e girassol (Helianthus annuus l.) ornamental em vasos com fibra de cÃco e areia. / USE OF THE GROWTH REGULATOR DAMINOZIDE IN THE CULTURE OF ORNAMENTAL PEPPER (Capsicum annuum L.) AND SUNFLOWER (Helianthus annuus L.) IN POTS WITH COCONUT FIBER AND SAND
O cultivo de girassol e pimenta como plantas ornamentais envasadas vem se destacando na floricultura por serem produtos inovadores e de grande atratividade, fazendo-se inÃdito a produÃÃo e conduÃÃo de pesquisas com estas espÃcies nas condiÃÃes climÃticas de Fortaleza e CearÃ. Visando a manipulaÃÃo da arquitetura de plantas, na busca de menores al

3. Gene expression analysis in sweet orange in response to Xanthomonas axonopodis pv. citri and Xanthomonas axonopodis pv. aurantifolii / Expressão diferencial de genes de laranja doce em resposta a infecção por Xanthomonas axonopodis pv. citri e axonopodis pv. aurantifolii
The most aggressive form of the citrus canker disease is caused by the bacteria Xanthomonas axonopodis pv. citri (Xac), which can infect all commercial varieties or species of citrus. In addition to Xac, Xanthomonas axonopodis pv. aurantifolii (Xaa) causes a weaker form of the disease, known as cancrose C, which is restricted to Mexican Lime (Citrus aurantif

4. INDUCTION OF FERN SPORE GERMINATION*
Light-induced germination of Anemia spores can be inhibited by AMO-1618, a selective inhibitor of gibberellin biosynthesis. The inhibitor has no effect on gibberellin-induced dark germination and its inhibition of light-induced germination can be reversed by supplying gibberellin. Barley-endosperm bioassay of concentrates of medium in which spores are imbibe
5. Characterization and Role of an Endogenous Inhibitor in the Induction of Cold Hardiness in Acer negundo1
An inhibitor extracted from short day treated Acer negundo leaves was compared to abscisic acid in 4 different solvent systems. The chromatographic properties of abscisic acid and the inhibitor were in very close agreement. Treatment of Acer negundo plants under non-hardening preconditions (long days) with either the inhibitor or abscisic acid increased hard
6. Regulation of Cold Hardiness in Acer negundo12
The application of gibberellin to Acer negundo either during or after a short photoperiod strikingly lowered the amount of hardiness obtained after 4 weeks in darkness at 5°. Two growth retardants, B9 and Amo 1618, the latter of which interferes with gibberellin synthesis, brought about hardiness increases under long photoperiods. The naturally occurring in
7. Hormonal Interactions in the Control of Arabidopsis Hypocotyl Elongation1
The Arabidopsis hypocotyl, together with hormone mutants and chemical inhibitors, was used to study the role of auxin in cell elongation and its possible interactions with ethylene and gibberellin. When wild-type Arabidopsis seedlings were grown on media containing a range of auxin concentrations, hypocotyl growth was inhibited. However, when axr1-12 and 35S

8. The Level of Phytohormones in Monoecious and Gynoecious Cucumbers as Affected by Photoperiod and Ethephon 1
The endogenous levels of auxin, gibberellin, and inhibitors were followed in monoecious and gynoecious cucumber (Cucumis sativus L.) plants, and in plants treated with the ethylene-releasing compound Ethephon (2-chloroethyl phosphonic acid). Higher auxin inhibitor and lower gibberellin levels were associated with female tendency. The endogenous level of gibb
9. Metabolism of Tritiated Gibberellins in d-5 Dward Maize: II. [3H]Gibberellin A1, [3H]Gibberellin A3, and Related Compounds 1
After 30 minutes of incubation of young leaf sections of d-5 maize (Zea mays L.) in [3H]gibberellin A1 ([3H]GA1), the metabolite [3H]GA8 was present in significant amounts, with a second metabolite, [3H]GA8-glucose ([3H]GA8-glu), appearing soon after. A third [3H]GA1 metabolite, the polar uncharacterized conjugate [3H]GA1-X, took more than 1 hour to appear.
10. Hormonally regulated programmed cell death in barley aleurone cells
Cell death was studied in barley (cv Himalaya) aleurone cells treated with abscisic acid and gibberellin. Aleurone protoplasts incubated in abscisic acid remained viable in culture for at least 3 weeks, but exposure to gibberellin initiated a series of events that resulted in death. Between 4 and 8 days after incubation in gibberellin, >70% of all protoplast
11. Mechanism of Gibberellin-Dependent Stem Elongation in Peas 1
Stem elongation in peas (Pisum sativum L.) is under partial control by gibberellins, yet the mechanism of such control is uncertain. In this study, we examined the cellular and physical properties that govern stem elongation, to determine how gibberellins influence pea stem growth. Stem elongation of etiolated seedlings was retarded with uniconozol, a gibber
12. The Angiosperm Gibberellin-GID1-DELLA Growth Regulatory Mechanism: How an “Inhibitor of an Inhibitor” Enables Flexible Response to Fluctuating Environments
The phytohormone gibberellin (GA) has long been known to regulate the growth, development, and life cycle progression of flowering plants. However, the molecular GA-GID1-DELLA mechanism that enables plants to respond to GA has only recently been discovered. In addition, studies published in the last few years have highlighted previously unsuspected roles for
