Substantial equivalence in transgenic barley
Ontology highlight
ABSTRACT: In this study, possible adverse effects of transgene expression in field-grown barley were assessed in relation to the influence of genetic background and to the impact of interaction with arbuscular mycorrhiza fungi. The deposited microarray data originate from a parallel transcript profiling, metabolome profiling and metabolic fingerprinting approach with the wild type cultivars Golden Promise (GP) and Baronesse (B) as well as barley transgenics with i) seed-specific expression of (1,3-1,4)-ß-glucanase (GluB) being introgressed from the Golden Promise (GP) into the cultivar Baronesse (B) and ii) ubiquitous expression of codon-optimized Trichoderma harzianum endochitinase (ChGP). Our conclusion from the results is that cultivar-specific differences and even the presence of few introgressed alleles exceed the effects on transcriptome and metabolome caused by transgene expression. Mycorrhization was shown to have more prominent effects on the metabolome than on the transcriptome.
