| الوصف: | In an attempt to determine whether fungal auxin affects host plant gene expression during mycorrhizal formation, an auxin upregulated cDNA, Pp-iaa88, was isolated by differential screening of a cDNA library made from auxin-treated Pinus pinaster roots.Pp-iaa88 codes for a polypeptide that shares extensive homology to auxin-inducible Aux/IAA proteins, which are supposed to act as transcription factors. Cycloheximide did not inhibit auxin-induced mRNA accumulation, indicating that Pp-iaa88 upregulation is a primary (direct) auxin response.The level of Pp-iaa88 transcripts in roots increased following inoculation with either an indoleacetic acid-overproducing mutant or a wild-type strain of the ectomycorrhizal fungus Hebeloma cylindrosporum. With both strains, mRNA accumulation was detectable as soon as fungal hyphae reached the root and it increased during differentiation of symbiotic structures. The kinetics of Pp-iaa88 transcript accumulation was closely connected with the dynamics of symbiosis establishment and was more rapid with the mutant than with the wild-type strain.As a putative transcription factor expressed at the very early stages of symbiosis establishment, Pp-iaa88 could play a key role in mycorrhizal formation. |
