dc.description.abstract
Plants are challenged by both above- and belowground herbivores which may
indirectly interact with each other via herbivore-induced changes in plant
traits; however, little is known about how genetic variation of the host plant
shapes such interactions. We used two genotypes (M4 and E9) of Solanum
dulcamara (Solanaceae) with or without previous experience of aboveground
herbivory by Spodoptera exigua (Noctuidae) to quantify its effects on
subsequent root herbivory by Agriotes spp. (Elateridae). In the genotype M4,
due to the aboveground herbivory, shoot and root biomass was significantly
decreased, roots had a lower C/N ratio and contained significantly higher
levels of proteins, while the genotype E9 was not affected. However,
aboveground herbivory had no effects on weight gain or mortality of the
belowground herbivores. Root herbivory by Agriotes increased the nitrogen
concentration in the roots of M4 plants leading to a higher weight gain of
conspecific larvae. Also, in feeding bioassays, Agriotes larvae tended to
prefer roots of M4 over E9, irrespective of the aboveground herbivore
treatment. Fourier-Transform Infrared Spectroscopy (FT-IR) documented
differences in metabolic profiles of the two plant genotypes and of the roots
of M4 plants after aboveground herbivory. Together, these results demonstrate
that previous aboveground herbivory can have genotype-specific effects on
quantitative and qualitative root traits. This may have consequences for
belowground interactions, although generalist root herbivores might not be
affected when the root biomass offered is still sufficient for growth and
survival.
