abstract = {The plant kingdom contains an enormous diversity of
bioactive compounds which regulate plant growth and defends
against biotic and abiotic stress. Some of these compounds,
like flavonoids, have properties which are health supporting
and relevant for industrial use. Many of these valuable
compounds are synthesized in various pepper (Capsicum sp.)
tissues. Further, a huge amount of biomass residual remains
from pepper production after harvest, which provides an
important opportunity to extract these metabolites and
optimize the utilization of crops. Moreover, abiotic
stresses induce the synthesis of such metabolites as a
defense mechanism. Two different Capsicum species were
therefore exposed to chilling temperature (24/18 ℃ vs.
18/12 ℃), to salinity (200 mM NaCl), or a combination
thereof for 1, 7 and 14 days to investigate the effect of
these stresses on the metabolome and transcriptome profiles
of their leaves. Both profiles in both species responded to
all stresses with an increase over time. All stresses
resulted in repression of photosynthesis genes. Stress
involving chilling temperature induced secondary metabolism
whereas stresses involving salt repressed cell wall
modification and solute transport. The metabolome analysis
annotated putatively many health stimulating flavonoids
(apigetrin, rutin, kaempferol, luteolin and quercetin) in
the Capsicum biomass residuals, which were induced in
response to salinity, chilling temperature or a combination
thereof, and supported by related structural genes of the
secondary metabolism in the network analysis.},
