1. Effect of Cottonseed Meal Fermented with Yeast on the Lipid-related Gene Expression in Broiler Chickens
ABSTRACT Fermented cottonseed meal (FCSM) is widely used in poultry diets in China. This study was conducted to investigate the effect of FCSM on lipid-related gene expression in broilers. Initially, 180 broiler chickens (21-days-old, equal number of males and females) were randomly divided into three groups, with six pens per group and 10 birds per pen. The

2. Efeito da aplicação de 1-metilciclopropeno e etileno na fisiologia e no amadurecimento de mamões `Golden´ / Effect of 1-methylcyclopropene and ethylene on the physiology and ripening of Golden papaya
O mamão é um fruto climatérico, cujas transformações resultantes do amadurecimento ocorrem rapidamente após a colheita. O tratamento com 1- metilciclopropeno (1-MCP) tem sido testado para ampliar sua vida útil, entretanto, com resultados até então pouco consistentes. Pesquisas com peras, bananas e ameixas foram realizadas utilizando conjuntamente 1-

3. ACC sintase em cana-de-áçucar : estudos de regulação gênica e aplicação biotecnológica / Sugarcane ACC synthase : studies of gene regulation and biotechnology application
A cultura da cana-de-açúcar (Saccharum spp) está entre as mais importantes do Brasil, tendo o setor sucroalcooleiro grande importância econômica no país devido ao crescente consumo de álcool e açúcar. A fase de maturação no desenvolvimento da cana-de-açúcar é especialmente interessante, pois está diretamente relacionada com o teor de sacarose.

4. Induction of ethylene biosynthesis in Nicotiana tabacum by a Trichoderma viride xylanase is correlated to the accumulation of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase transcripts.
Xylanase (EIX) from the fungus Trichoderma viride elicits ethylene biosynthesis in leaf tissues of Nicotiana tabacum cv Xanthi but not in cv Hicks. The increase in ethylene biosynthesis is accompanied by an accumulation of 1-aminocyclopropane-1-carboxylic acid (ACC), an increase in extractable ACC synthase activity, and increases in ACC synthase and ACC oxid

5. The Multiple Roles of Conserved Arginine 286 of 1-Aminocyclopropane-1-Carboxylate Synthase. Coenzyme Binding, Substrate Binding, and Beyond1
A pyridoxal 5′-phosphate (PLP)-dependent enzyme, 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (S-adenosyl-l-Met methylthioadenosine-lyase, EC 4.4.1.14), catalyzes the conversion of S-adenosyl-l-methionine (AdoMet) to ACC. A tomato ACC synthase isozyme (LE-ACS2) with a deletion of 46 amino acids at the C terminus was chosen as the control enzyme for

6. Differential Expression of Three Members of the 1-Aminocyclopropane-1-Carboxylate Synthase Gene Family in Carnation1
We investigated the expression patterns of three 1-aminocyclopropane-1-carboxylate (ACC) synthase genes in carnation (Dianthus caryophyllus cv White Sim) under conditions previously shown to induce ethylene biosynthesis. These included treatment of flowers with 2,4-dichlorophenoxyacetic acid, ethylene, LiCl, cycloheximide, and natural and pollination-i

7. The 1-aminocyclopropane-1-carboxylate synthase gene family of Arabidopsis thaliana.
Genomic sequences encoding five divergent 1-aminocyclopropane-1-carboxylic acid (ACC) synthase polypeptides (ACC1, ACC2, ACC3, ACC4, and ACC5) have been isolated from Arabidopsis thaliana by using heterologous cDNAs and PCR fragments amplified from genomic DNA with degenerate oligonucleotide primers. Each gene is located on a different chromosome in the Arab

8. Cloning the mRNA encoding 1-aminocyclopropane-1-carboxylate synthase, the key enzyme for ethylene biosynthesis in plants.
Ethylene is the plant hormone that controls several features of plant growth and development. The rate-limiting step in its synthesis is the formation of the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC) from S-adenosylmethionine (AdoMet), catalyzed by ACC synthase. We have isolated a complementary DNA sequence encoding ACC synthase from zuc

9. In Vivo 1-Aminocyclopropane-1-Carboxylate Synthase Activity in Internodes of Deepwater Rice 1: Enhancement by Submergence and Low Oxygen Levels
Inasmuch as the activity of 1-aminocyclopropane-1-carboxylate (ACC) synthase cannot be measured in homogenates of deepwater rice internodes (Oryza sativa L.), we have employed an in vivo assay to determine the activity of this enzyme. This assay is based on the accumulation of ACC in tissue kept under N2. Submergence of whole plants or stem sections containi

10. S-Adenosylmethionine-Dependent Inactivation and Radiolabeling of 1-Aminocyclopropane-1-Carboxylate Synthase Isolated from Tomato Fruits 1
1-Aminocyclopropane-1-carboxylic acid (ACC) synthase was partially purified from the homogenate of wounded tomato (Lycoperiscon esculentum Mill.) pericarp tissue by (NH4)2SO4 fractionation followed by conventional column chromatography with diethylaminoethyl-Sepharose, Sephadex G-150, Affi-Gel blue and hydroxylapatite. The partially purified ACC synthase pre

11. Dynamic 1-Aminocyclopropane-1-Carboxylate-Synthase and -Oxidase Transcript Accumulation Patterns during Pollen Tube Growth in Tobacco Styles1
In flowering plants, pollination of the stigma sets off a cascade of responses in the distal flower organs. Ethylene and its biosynthetic precursor 1-aminocyclopropane-1-carboxylate (ACC) play an important role in regulating these responses. Because exogenous application of ethylene or ACC does not invoke the full postpollination syndrome, the pollination si

12. Chilling-Induced Ethylene Production in Cucumbers (Cucumis sativus L.) 1
1-Aminocyclopropane-1-carboxylic acid (ACC) level, ACC synthase activity, and ethylene production in cucumbers (Cucumis sativus L.) remain low while the fruit are held at a temperature which causes chilling injury (2.5°C) and increase rapidly only upon transfer to warmer temperatures. The increase in ACC synthase activity during the warming period is inhibi
