Abstract:
:The cherry rootstock 'Colt' line was transformed with a phytochrome A rice gene with the aim of altering light perception. Three transgenic events were chosen because of a modified developmental behavior. When red enriched light was supplied horizontally to stems, the PD3 transgenic line showed an increased rate of phytomer formation associated to a superior rate of plant growth compared to wild type (WT). Under the same light conditions, the PO1 and PA lines were less altered in morphology and development. When far-red enriched light was supplied, all transgenic lines had a reduced rate of growth, with the PD3 line being the most similar to the WT. The influence of the alien gene on root and leaf-associated bacteria was studied for a duration of 1 year. Significantly more culturable bacteria were recovered from PA lines than from PO1, PD3 and WT lines. On average, significantly more fluorescent pseudomonads were recovered from the rhizosphere of PA and PO1 lines than from PD3 and WT. No significant differences were detected in the number of bacteria recovered from the phyllosphere of transgenic and WT plant lines. A total of 143 Pseudomonas fluorescens strains isolated from rhizosphere of transgenic and WT lines were tested for their antagonistic activity against Phytophthora nicotianae and differences between bacteria derived from transgenic and WT were not detected. Fluorescent pseudomonads strains isolated from phyllosphere of PA and PO1 lines showed antagonistic activity against P. syringae pv. syringae, whereas no difference among the transgenic and WT lines was detected when fluorescent Pseudomonas strains were tested against P. syringae pv. mors-prunorum. Pathogenicity tests were conducted on rooted and micropropagated plants with P. s. pv. syringae and P. s. pv. mors-prunorum: in all assays, the PO1 lines were the most tolerant to P. s. pv. Syringae, and the PO1 and PD3 were tolerant to P. s. pv. mors-prunorum.
