Small nucleolar RNA R160 of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs. snoR160 was identified by computational screening of the rice "Oryza sativa" and is predicted to acts as a methylation guide for 25S ribosomal RNA in plants. snoR160 has also been alternatively named snoZ270 in rice. Small nucleolar RNA R160 Samm nucleolar RNA R160 (also known as snoR160) is a non-coding RNA (ncRNA) molecule identified in plants which functions in the modification of other small nuclear RNAs (snRNAs). This type of modifying RNA is usually located in the nucleolus of the eukaryotic cell which is
Plant genome assembly products were used to clone remaining gaps, and YACs allowed the characterization of telomere sequences. The resulting sequenced regions were 115.4 Mb of the 125 Mb predicted size of the genome and a total of 25,498 of protein-coding genes. To sequence and assemble the genome of Oryza Sativa (japonica), the same strategy was used. For Oryza Sativa a total of 3,401 mapped clones in a minimum tiling path were selected from the physical map and assembled. One of the most important crops in the world, maize (Zea mays), is the last plant genome project primarily based on Sanger BAC-by-BAC strategy.
