Annotated Information
Function
RL14 (rolling leaf 14) regulates leaf rolling, which is found to encode a 2OG-Fe (II) oxygenase of unknown function. the RL14 gene affects water transport in leaves by affecting the composition of the secondary cell wall. This change in water transport results in water deficiency, which is the major reason for the abnormal shape of the bulliform cells. RL14 mutant plants displayed smaller stomatal complexes and decreased transpiration rates, as compared with the wild type. Defective development could be rescued functionally by the expression of wild-type RL14.
Expression
Histochemistry, as well as qRT-PCR analysis, showed that RL14 was highly transcribed in leaves, leaf sheaths and roots. It was also detected in stems and glumes, although its expression in these organs was not as intense as that in the mature leaves, leaf sheaths and roots (Figure 1b).
Expression of RL14 mRNA was detected in the sclerenchymal cell layer of underemerged leaves and sheaths. In the mature leaf, RL14 mRNA accumulated mainly in the mesophyll cells that surrounded the vasculature (Figure 1c).

The RL14 gene was mapped first to an interval between the simple sequence repeat (SSR) markers RM3123 and RM1162 on the long arm of chromosome 10.
Finally, the RL14 locus was mapped to a 24.5-kb DNA region between the InDel marker SID2 and SSR marker SW24 on a single bacterial artificial chromosome, AC079874.
Four annotated candidate genes, which encoded a polyol transporter (Os10g40950.1), a 2OG-Fe (II) oxygenase family protein (Os10g40960.1), a flavonol synthase (Os10g40990.1) and a retrotransposon protein (Os10g41000), were located in the 24.5-kb DNA region.
RL14 was related most closely to members of the 2OG-Fe (II) oxygenase family from rice and sorghum (Figure 2b). Orthologous of RL14 was identified in other species, such as maize, Arabidopsis, Papaver somniferum, Vitis spp and Ricinus communis (Figure 2b).
