Identification and Phenotypic Characterization of ZEBRA LEAF16 Encoding a β-Hydroxyacyl-ACP Dehydratase in Rice.

ABSTRACT: The chloroplast is a self-independent organelle and contains its own transcription and translation systems. The establishment of genetic systems is vital for normal plant growth and development. We isolated a rice zebra leaf 16 (zl16) mutant derived from rice cultivar 9311. The zl16 mutant showed chlorotic abnormalities in the transverse sectors of the young leaves of seedlings. The use of transmission electron microscopy (TEM) demonstrated that dramatic defects occurred in variegated zl16 leaves during the early development of a chloroplast. Map-based cloning revealed that ZL16 encodes a β-hydroxyacyl-ACP dehydratase (HAD) involved in de novo fatty acid synthesis. Compared with the wild type, a missense mutation (Arg164Trp) in the zl16 muta
