Carotenoids are isoprenoid pigments synthesized exclusively by plants and microorganisms
and play critical roles in light harvesting, photoprotection, attracting pollinators and …

Background Bixin or annatto is a commercially important natural orange-red pigment
derived from lycopene that is produced and stored in seeds of Bixa orellana L. An enzymatic …

Bixin is an apocarotenoid derived from Bixa orellana L. well known as a food colorant along
with its numerous industrial and therapeutic applications. With the current surge in usage of …

Diverse morphological, cellular and physiological changes occur during seed maturation in
Bixa orellana when the seed tissues form specialized cell glands that produce reddish latex …

The effect of salt stress on pigment synthesis and antioxidant enzyme activity as well as in
the genes involved in the biosynthetic pathway of bixin was studied. The 14-day germinated …

Carotene cleavage dioxygenases (CCDs) are a large family of Fe2+ dependent enzymes
responsible for the production of a wide variety of apocarotenoids, such as bixin. Among the …

Carotenoid cleavage dioxygenases (CCDs) are a class of enzymes involved in the
biosynthesis of a broad diversity of secondary metabolites known as apocarotenoids. In …

Main conclusion Genetic transformation allows for greater bixin or norbixin production in
achiote. Knowledge of genes that control the biosynthesis of these important secondary …

The current study was undertaken to analyse the effect of short-term UV-B and UV-C
