Phenotypic variation in isoprenoid content in the AI-RIL mapping
population
Next, the seven isoprenoid compounds described above (carotenoids,
chlorophylls, Dols, phytosterols, plastoquinone, Prens, and tocopherols)
were quantified in 146 lines of the EstC mapping population and its
parental lines (Col-0 and Est-1). The profiles of analyzed isoprenoids
were similar to those described above for different accessions, while
the level of particular compounds varied among lines of the mapping
population (shown in details in Figure 1B, Figure S3, and Table 1). The
range of the content of Prens (Figure 1B), Dols (Figure 1B) and other
compounds (Figure S3) was broader than that observed for both parental
lines, which might suggest that several loci within the EstC population
contribute to this phenomenon and it may be explained by the presence of
transgressive segregation.
