1-aminocyclopropane-1-carboxylic acid oxidase (ACO) enzyme is a member of the Fe II-dependent family of oxidases/oxygenases which require Fe2+ as a cofactor, ascorbate as a cosubstrate and CO2 as an activator. This enzyme catalyses the terminal step in the plant signaling of ethylene biosynthetic pathway. A 948 bp fragment of the ACO1 gene cDNA sequence was(More)
Single Strand-Preferring Nucleases (SSPNs) have been implicated in the triggering and progress of cell death pathways, including senescence in higher plants, though the biological roles of such enzymes are still obscure. In the present study, heterotrophic cell suspension cultures of Oryza sativa L. (rice) cv Taipei 309 were used to investigate changes in(More)
BACKGROUND AND OBJECTIVES Astaxanthin, an orange-red carotenoid pigment, acts as a protective agent against oxidative damage to cells in vivo. The astaxanthin synthetase gene (crtS) size consists of 3995 bp. This gene has been suggested to catalyse β-carotene to astaxanthin in Phaffia rhodozyma. The aim of this research was to find any possible changes in(More)
BACKGROUND AND OBJECTIVES Chlorophyceae are important constituents of marine phytoplankton. The taxonomy of Chlorophyceae was traditionally based solely on morphological characteristics. In the present research project, genetic diversity was investigated to analyze five species of Chlorophyceae from waters of the Persian Gulf. MATERIALS AND METHODS A(More)
