Astaxanthin is a carotenoid pigment responsible for the red color of the flesh of many marine animals. There is an increasing interest in the use of astaxanthin in aquaculture, chemical, pharmaceutical, and alimentary industries. Phaffia rhodozyma has been identified as the best biological source of astaxanthin. Mutagenesis was carried out using different(More)
* Corresponding author 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(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)
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)
BACKGROUND AND THE PURPOSE OF THE STUDY Artemisinin is one of the most effective medicine against malaria, which is produced naturally by Artemisia annua in low yield. It is produced in a metabolic pathway, in which several genes and gene products are involved. One of the key genes in this pathway is am1, which encodes amorpha-4, 11-diene synthase (ADS), a(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)
Tomato (Solanum lycopersicum L.) is the primary model for the study of fleshy fruits, and research on this species has elucidated many aspects of fruit physiology, development, and metabolism. However, for advancing such studies at molecular biology levels, the RNA isolation from fruit tissues is often essential. The RNA isolation from tomato fruits is(More)
