Research Abstract |
To elucidate the function of LEA proteins inferred to be involved in the response to environmental stress in woody plants, the cDNAs of LEA proteins were isolated from Lombardy poplar and were investigated. Among of the poplar LEA genes, the expression of PnLEA1 was induced by drought, high salinity and low temperature. We found that PnLEA1 plays an important role for initial adaptation to salinity stress, because the expression of PnLEA1 recovered the delay in cell growth of Escherichia coli under high salinity. However, the PnLEA1-overexpressed poplar plants were withered after about 14 days without watering as well as empty vector control plants.
