Gene organization of novel snoRNA gene clusters. (A) Novel snoRNA gene cluster: cloning of snoR145 (Ath-122) and examination of flanking sequences identified snoR68 and three snoRNA genes for which partial sequences had been identified previously but were not recognized as snoRNAs (Ath-319, Ath-122, Ath-118a and Ath-118b) (21). (B) Extended snoRNA gene cluster: two clusters containing gene copies of snoR19, snoR20 and snoR38Y (black boxes) were identified previously (18). Further three genes were added to the first cluster: snoR88-1 and snoR64 (21) and snoR136 was predicted. (C) Intronic snoRNA genes and gene cluster: two of the novel H/ACA snoRNAs were found in introns of mRNAs with snoR155 having three variants. White boxes, exons; black boxes, snoRNAs.
