Abstract
A cDNA library prepared from rice seedlings is subjected to screening using Arabidopisis proline transporter gene cDNA as a probe. The positive clones thus obtained are subcloned and examined for their length through restriction enzyme treatment and 5′ and 3′ terminal nucleotide sequences to give a rice proline transporter gene cDNA-containing clone. This cDNA is sequenced and, based on the results of homology searching, a rice proline transporter gene is identified which shows high (68%) homology (amino acid level) with the Arabidopsis-derived ones and is very similar in transmembrane domain (hydropathy plot analysis) and expression pattern (Northern analysis) thereto.
