Small nucleolar RNA SNORD15 C/D family function in directing site-specific 2'-O-methylation of substrate RNAs. U15 is predicted to guide the 2'O-ribose methylation of 28S ribosomal RNA (rRNA) residue A3764. In humans there are two closely related copies of the U15 snoRNA (called SNORD15A and SNORD15B). They are both encoded in the introns of the ribosomal protein S3. In "Xenopus laevis" it is located within the introns of ribosomal protein S1 snoR75 from "Arabidopsis thaliana" and homologues in rice "Oryza sativa" and other plants are alternatively known as U15, and, despite a significantly shorter sequence length, appear to be related.

Scirpophaga nivella orange anal tuft, sometimes brownish in the female. The larvae are off white with a reddish dorsal line. Major feeding plant is sugarcane, besides "Oryza sativa", "Scirpus", "Cyperus", "Eleocharis" (including "Eleocharis dulcis") and "Calidum articulatum" are also susceptible as feeding plants of the moth. Caterpillars bore into midrib, by leaving red markings and small holes on the leaves. Then it bore in the upper portion of stem, causing "dead heart" symptoms. Gradually, side branches start growing from a lower node, giving a characteristic "bunchy top" appearance to the plant. Most effective method is using biological predators and parasitoids. It is
