It is a major source of dragon’s blood, a precious traditional medicine in China. DcHLH1, a bHLH transcription factor identified in yeast one-hybrid screening, was capable of both binding to the promoter and activating the transcription of DcF3’H by ~10-fold. Dracaena Cambodiana is the dragon’s blood tree that yields a dragon’s blood. Phytohormones are central to the plant growth and development. The American diet is filled with processed foods, high fructose corn syrup, high sugar and trans fats. Reactive oxygen species (ROS) are widely produced in different cellular compartments under both biotic and abiotic stress conditions. The reads were assembled into 2,640,704 contigs with an N50 length of 1.87 kb, and a 1.05 Gb assembly was finally assembled with 2,379,659 scaffolds. In short, an in vivo activity assay platform for rapidly examining the biological activity of commercial dragon blood samples was successfully established here, which complements the current HPLC-based assay method. It grows in low-elevation forests (0–300 m) having dry and sandy soils. The main chemical compounds in dragon’s blood are flavonoids.

This report represents the first genome-wide characterization of a Dracaena species in the Asparagaceae. Dracaena Draco is by far the most popular landscaping feature plant for South coast and Sydney landscapes. The stem of these two, ]. Abstract: Dragon’s blood that is extracted from Dracaenaplants has been widely used as traditional medicine in various ancient cultures. This plant yields dragon’s blood — a bright red resin used since ancient times as medicine, body oil, varnish, incense and dye. However, the genetics of the genus Dracaena and the formation mechanism of dragon’s blood remain poorly understood. Dragon’s blood is a traditional medicine that is produced mainly from Dracaenas plants and is widely used in the world. Among all 53,700 predicted genes, 158 genes involved in cell wall and plant hormone synthesis and reactive oxygen species scavenging showed altered regulation during the formation of dragon’s blood. ; Guo, D.; Wang, Y.; Dai, H.F.

Furthermore, 97.75% of the 267,243 simple sequence repeats identified from these scaffolds were mononucleotide, dinucleotide, and trinucleotide repeats. In the last half of the century, Chinese scientists have extensively investigated the production of dragon's blood from these two Dracaena species, whereas these results have not been previously systematically summarized, as in the present paper. Such knowledge might aid in the global conservation of wild Dracaena species and contribute to understanding dragon blood formation mechanisms, eventually assisting in the efficient utilization of limited Dracaena plant resources for the sustainable production of dragon's blood. We identified a total of 68 simple sequence repeat (SSR) markers in the chloroplast genome.
