The establishment of a plant-pathogen interaction involves changes in gene expressions in both organisms. To isolate Helianthus annuus genes whose expression is induced during processes of resistance to Plasmopara halstedii, a comparison of the expression pattern of healthy sunflowers was made with sunflowers infected with 2 races of P. halstedii, either virulent or avirulent, using differential display of mRNA. A full-length cDNA, HaAC1, representing a sunflower gene whose expression is enhanced during early stages of the incompatible interaction, was isolated. Different timing of RNA accumulation is observed between compatible and incompatible combinations. Sequence analysis and database search revealed significant homology with auxin-induced genes from plants. The expression of this gene, is also induced after treatment with 2,4-dichlorophenoxyacetic acid (2,4-D), salicylic acid (SA) and wounding. |
