abstract = "Late blight (LB) caused by the Phytophthora infestans is a
devastating tomato disease, distributed worldwide. Tomato wild species could
be a potential source of resistance, however, there are little data about their
biochemical response to LB infection. Therefore the aim of the study was to
evaluate total phenolic and total flavonoid content and antioxidative activity in
the leaves of wild (Solanum pimpinellifolium) and cultivated genotype (Bizon)
depending on disease severity. S. pimpinellifolium compared to Bizon was
less susceptible and had five times lower disease severity index (11% and
55% respectively). Additionally, during the disease progression wild
genotype showed a much slower decrease of total biochemical parameters
compared to the cultivated one. Parameters such as total phenolic content
(TP), DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging test and ABTS
(2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)) radical scavenging
activity in the symptomless leaves and the leaves infection 10-25% remained
the same in S. pimpinellifolium. The susceptible genotype Bizon had about
40% of leaves with the disease severity 25-50%, and a rapid decrease of all
biochemical parameters. A strong negative correlation was observed between
late blight infection and biochemical parameters in Bizon, while in S.
pimpinellifolium late blight infection negatively correlated only with TP, TF
(total flavonoid content) and total antioxidant activity (TAA).",
