Annotation confidence Low

Comments

miR426 was predicted and validated using procedures described in [1], but the sequence itself was not reported (Takashi Soyano, pers. comm.). The status of this sequence as a miRNA has been questioned on the basis of lack of conservation in genomes other than Arabidopsis and rice, moderately poor precursor hairpin structure, lack of identified targets, and low Northern blot signal [2]. This sequence may therefore be removed in subsequent data releases.
