Search For Rice Genes Relating To A Salt Tolerance

Abstract

The high salt concentration in soil is one of the important factors for growth and yield of crops. Rice is not so tolerant to salt, but have the mechanism for the exclusion of salt from a cytoplasm. The genes for salt tolerance were selected by rice FOX (Full-length cDNA overexpressor gene) hunting system and microarray technique using a slide glass spotted 44k oligonucleotides encoding rice genes (Agilent Technologies, Inc.) We selected genes concerned with salt tolerance by FOX hunting, such as the genes for zinc finger containing proteins. Many genes were selected as a gene functioning salt tolerance by microarray technique. The genes selected by FOX hunting did not appeared in the genes result from the microarray experiment. However, the genes selected by both methods were categorized in the groups having a similar function.
