Abstract
|
|
|
|
A wound-inducible cDNA clone (AWI 34) was obtained from the cDNA library of Arabidopsis thaliana by differential screening. The corresponding gene expression was induced rapidly reaching a maximum level in approximately 1.5 h and then progressively reducing after wounding. The predicted amino acid sequence of AWI 34 has 57% homology with the DC 1.2 gene product. The DC 1.2 product is known to be temporarily induced during the initiation of somatic embryogenesis in carrot cells cultured in an auxin(2,4-D)-free medium. The AWI 34 gene was induced by an exogenous 2,4-D treatment on normal plant tissue. The AWI 34 gene was also induced by other environmental stresses such as drought, high-salt, and lowtemperature conditions.
