Black rice Black rice Black rice (also known as purple rice) is a range of rice types of the species "Oryza sativa" L., some of which are glutinous rice. Varieties include Indonesian black rice, Philippine "balatinaw" rice, and Thai jasmine black rice. Black rice is known as "chak-hao" in Manipur, an Indian state on the eastern border with Myanmar, where desserts made from black rice are served at major feasts. Black rice is a source of iron, vitamin E, and antioxidants. The bran hull (outermost layer) of black rice contains one of the highest levels of anthocyanins found in food. The grain
Helitron (biology) Helitron (biology) Helitrons are one of the three groups of eukaryotic class 2 transposable elements (TEs) so far described. They are the eukaryotic rolling-circle transposable elements which are hypothesized to transpose by a rolling circle replication mechanism via a single-stranded DNA intermediate. They were first discovered in plants ("Arabidopsis thaliana" and "Oryza sativa") and in the nematode "Caenorhabditis elegans", and now they have been identified in a diverse range of species, from protists to mammals. Helitrons make up a substantial fraction of many genomes where non-autonomous elements frequently outnumber the putative autonomous partner. Helitrons seem to have a major role
