چکیده
Chlorophyll can be chosen as the fundamental pigment of life. Related to it is protoheme, the red pigment of blood. These substances are found to be biosynthesized from the same parent substance called uroporphyrinogen-III. This paper covers research over a period of 19 years, which has gradually revealed the details of Nature's pathway to uroporphyrinogen-III.

have been bred with altered flower color using genetic engineering approaches. One of the most effective applications is the reduction of flower pigments by suppression of involved enzymes in their biosynthesis pathways. RNA interference (RNAi) has provided an effective tool for the knock down of genes involved in the production of flower pigments. In this study, a chi-RNAi construct was design...
متن کاملFunctional Analysis of a Pomegranate (Punica granatum L.) MYB Transcription Factor Involved in the Regulation of Anthocyanin Biosynthesis
Background: Pomegranate fruit (Punica granatum L.) is a rich source of anthocyanin pigments resulting in vibrant colours and anti-oxidant contents. Although the intensity and pattern of anthocyanin biosynthesis in fruit are strongly influenced by R2R3-MYB transcription factors, little is known about the regulation and role of MYB in anthocyanin pathway of pomegranate. Objectives: The present st...
متن کاملThe Effect of Postharvest Methyl Jasmonate Treatment on Ethylene Biosynthesis, Antioxidant Capacity and Shelf Life of Strawberry
Strawberry is one of the highly consumed fruits which are cultivated in wide areas of the world. The most important problem of the strawberry is low storability and high postharvest losses; hence, more than 50% of harvested fruit is lost in Iran. The purpose of this research was to investigate biochemical and shelf life reaction of Camarosa cultivar to different concentrations of methyl jasmona...

متن کاملPigments and citrinin biosynthesis by fungi belonging to genus Monascus.
Citrinin is a mycotoxin, which is produced by fungi belonging to the genus Monascus, known in biotechnology as producers of azaphilone pigments. The relation between biosynthesis of these secondary metabolites was investigated in different species of the genus Monascus in batch-culture at the following cultivation conditions: T = 28 degrees C, agitation 220 rpm, and a medium, which induce citri...
