- ... VLCFAs are the main components of cuticular wax, which covers and protects plants from physical and biological stresses. However, the effect of fatty acid composition or the physiological role of VLCFAs on plant development under normal growth conditions is not well understood. We analyzed loss-of-function mutants of ONION1 (ONI1) which encodes fatty acid elongase (β-ketoacyl CoA synthase) catalyz ...

- ... We identified 12 PIN genes in rice which encode efflux carrier proteins of phytohormone auxin. Phytogenetic analysis showed that 11 genes were categorized into branches with Arabidopsis PIN genes and one had no close homologue in Arabidopsis. RT-PCR analysis showed expression of 10 PIN genes in various organs depending on genes. No expression of OsPIN3b was detected in the organs examined. OsPIN1b ...

- ... Organisms are covered extracellularly with cuticular waxes that consist of various fatty acids. In higher plants, extracellular waxes act as indispensable barriers to protect the plants from physical and biological stresses such as drought and pathogen attacks. However, the effect of fatty acid composition on plant development under normal growth conditions is not well understood. Here we show tha ...
