Plant Physiology: Chloroplast F And M Thioredoxins Discovered In …
Science Daily – Science Daily (press release) – Oct 17, 2007
In chloroplasts TRXs regulate numerous enzymes involved in the transformation of carbon into sugars. They also function to regulate the photosynthetic production of ATP the energy currency of all living organisms and in fatty acid synthesis. In a report to be published in the November issue of Plant Physiology researchers have found that the f and m type plant thioredoxins previously thought to be localized only in chloroplasts are also found in other nonphotosynthetic tissues where they may have multiple functions. A team from the laboratory of Dr. Mariam Sahrawy of the Estaci¨®n Experimental del Zaidin in Granada Spain established the presence of these redox proteins in tissues other than the chloroplast by fusing the promoters of these genes to a visible reporter molecule ¦Â-glucuronidase (GUS) and by expression analysis in situ hybridization and immunological analysis. All the different types of plant TRXs are encoded in the nucleus. The f and m types were isolated from chloroplasts and function there in light-regulated reactions related to photosynthesis… ther studies have shown that TRXs can function directly as antioxidants or in signaling pathways that sense reactive oxygen species and can thus protect plants against oxidative damage. Sahrawy and her team are now concentrating on analyzing the specific functions of these TRXs in different stages of plant development and under different physiological conditions. Knowledge of the diverse functions of these versatile proteins may be important in engineering drought and heat tolerant plants and in helping to protect plants against oxidative damage under stress conditions.

Tehran Times – Oct 17, 2007
Annually 680000 tons of ammonia will be produced by the project in which 142 million euros and 540 billion rials (57. 7 million dollars) have been invested. The project is under the license of a Swiss company and Iran?s Petrochemical Designing and Engineering Company does logistical affairs. Executive operations began in 2002 in an area of six hectares in Mahshahr southern Iran. The project is estimated to get ready for operation by the end of the current Iranian calendar year (March 19 2008).
