Comments

The A. thaliana jaw-D mutant has crinkly leaves and fruits, delayed flowering time and greenish petals. The jaw-D phenotype is caused by the over-expression of miR319 (also therefore known as miR-JAW), which is produced from a ~500 base long primary transcript RNA [1]. The mir-JAW microRNA is expressed in two forms, 20 and 21 nt, differing by the presence of the 3' terminal U. Cloned microRNA sequence was obtained from the jaw-D mutant. This miR has been shown targets TCP genes for cleavage [1]. This sequence is located on BAC F9D16. miR-JAW has a homologue located in BAC MBK23 (MI0000545). The mature excised miR shows sequence similarity to miR159 (MI0000189, MI0000218).
