Table I.
Transcript levels of MtCCD1 in extracts of nonmycorrhizal and mycorrhizal wild-type roots after 7 or 9 weeks of fungal colonization by G. intraradices as determined by real time RT-PCR from three biological replicates
For comparison, additional data were obtained from a gene involved in early steps of apocarotenoid biosynthesis (MtDXS2-1) and from an arbuscule molecular marker gene (MtPT4).
