Comparison of gene expression under in vitro and ex vitro conditions during rooting of grape cuttings through mRNA differential display
2005
An mRNA differential display (DD) analysis during rooting in grape cuttings was carried out to determine whether gene expression patterns differed under in vitro and ex vitro conditions. The four tissue samples for differential display and subsequent Northern hybridization analyses included control stem tissue from in vitro and ex vitro sources, microcuttings planted in MS based in vitro rooting medium and softwood cuttings planted in ex vitro soil medium, both collected 48 h after planting. DD autoradiographs showed gross similarity in banding pattern between in vitro and ex vitro stem tissue, whether constitutive or induced. Northern blot analysis of a few bands that appeared to be differentials did not indicate them as true positives. The results suggested that gene expression pattern during physiological processes such as rooting may be identical under in vitro and ex vitro conditions.
