Abstract
Rush (Juncus sp) is one of monocotyledon plants to be tolerant to high salt conditions, growing along marsh and seashore. There are few reports on the mechanism of salt tolerance in the rush. To analyze the molecular mechanisms for salt tolerance in the rush, functional screening of cDNAs encoding proteins concerning to salt tolerance in the halophytes was performed using Escherichia coli as a host organism. In this screening, cDNAs encoding proline-rich arabinogalactan protein homolog were successfully isolated. The date suggested that proline-rich protein might play an important role in salt tolerance mechanism of the rush.
