Anethum graveolens L. (dill) has been used in ayurvedic medicines since ancient times and it is a popular herb widely used as a spice and also yields essential oil. It is an aromatic and annual herb of apiaceae family. The Ayurvedic uses of dill seeds are carminative, stomachic and diuretic. There are various volatile components of dill seeds and herb; carvone being the predominant odorant of dill seed and a-phellandrene, limonene, dill ether, myristicin are the most important odorants of dill herb. Other compounds isolated from seeds are coumarins, flavonoids, phenolic acids and steroids. The main purpose of this review is to understand the significance of Anethum graveolens in ayurvedic medicines and non-medicinal purposes and emphasis can also be given to the enhancement of secondary metabolites of this medicinal plant.

Haem oxygenase (HO) degrades free haem released from haem proteins with the generation of ferrous iron (Fe2+), biliverdin-IXα (BV-IXα), and carbon monoxide (CO). The mechanism of haem cleavage has been conserved between plants and other organisms even though the function, subcellular localization, and cofactor requirements of HO differ substantially. The crystal structure of HO1, a monomeric protein, has been extensively reported in mammals, pathogenic bacteria, and cyanobacteria, but no such reports are available for higher plant HOs except a predicted model for pea HO1. Along with haem degradation, HO performs various cellular processes including iron acquisition/mobilization, phytochrome chromophore synthesis, cell protection, and stomatal regulation. To date, four HO genes (HO1, HO2, HO3, and HO4) have been reported in plants. HO1 has been well explored in cell metabolism; however, the divergent roles of the other three HOs is less known. The transcriptional up-regulation of HO1 in plants responds to many agents, such as light, UV, iron deprivation, reactive oxygen species (ROS), abscisic acid (ABA), and haematin. Recently the HO1/CO system has gained more attention due to its physiological cytoprotective role in plants. This review focuses on the recent advances made in plant HO research involving its role in environmental stresses. Moreover, the review emphasizes physiological, biochemical, and molecular aspects of this enzyme in plants.
