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 Arabidopsis genome. The genes are differe...
متن کاملDifferential expression and internal feedback regulation of 1-aminocyclopropane-1-carboxylate synthase, 1-aminocyclopropane-1-carboxylate oxidase, and ethylene receptor genes in tomato fruit during development and ripening.
We investigated the feedback regulation of ethylene biosynthesis in tomato (Lycopersicon esculentum) fruit with respect to the transition from system 1 to system 2 ethylene production. The abundance of LE-ACS2, LE-ACS4, and NR mRNAs increased in the ripening fruit concomitant with a burst in ethylene production. These increases in mRNAs with ripening were prevented to a large extent by treatmen...
متن کاملIsolation, Cloning and Sequence Analysis of 1-Aminocyclopropane-1-Carboxylate Deaminase Gene from Native Sinorhizobium meliloti
Background: Many plant growth-promoting bacteria including Rhizobia contain the 1-aminocyclopropane-1-carboxylate (ACC) deaminase enzyme that can leave ACC, and thereby lower the level of ethylene in stressed plants. Drought and salinity are the most common environmental stress factors for plants in Iran. Objectives: The main aim of this research was development of bio-fertilizers containing A...
متن کاملProperties and Partial Purification of 1-Aminocyclopropane-1-carboxylate Synthase.
We studied the regulation of 1-aminocyclopropane-1-carboxylate (ACC) synthase activity in tomato (Lycopersicon esculentum Mill.) fruit tissue and attempted the purification of this enzyme. The increase of ACC synthase activity in wounded tomato pericarp was inhibited by cordycepin and cycloheximide. Density labeling studies showed a 0.75% increase in the buoyant density of ACC synthase isolated...
متن کاملNucleotide Sequence of the Nicotiana tabacum cv Xanthi Gene Encoding 1-Aminocyclopropane-1-Carboxylate Synthase.
Ethylene is a plant hormone that influences many aspects of plant growth and development (10). The biosynthetic pathway of ethylene production in higher plants is well defined. The rate-limiting step in this pathway is the reaction catalyzed by ACC' synthase (S-adenosyl-L-methionine methyl-thioadenosine-lyase, EC 4.4.1.4), which converts Sadenosyl-L-methionine to ACC. Tobacco (Nicotiana tabacum...
