Complex patterns in tolerance and resistance to pests and diseases underpin the domestication of tomato

Abstract: Summary A frequent hypothesis explaining the high susceptibility of many crops to pests and diseases is that, in the process of domestication, crops have lost defensive genes and traits against pests and diseases. Ecological theory predicts trade‐offs whereby resistance and tolerance go at the cost of each other. We used wild relatives, early domesticated varieties, traditional local landraces and cultivars of tomato (Solanum lycopersicum) to test whether resistance and tolerance trade‐offs were phylogenetic… Show more

“…In addition, wild relatives and landraces were more susceptible to P. infestans than modern tomato genotypes. These results contrast with the general 'domestication theory, ' which presumes that domesticated cultivars should be highly sensitive while also exhibiting reduced genetic diversity (Yamasaki et al, 2005;Gaillard et al, 2018;Ferrero et al, 2020). In the case of P. infestans, greater resistance in modern germplasm is likely due to targeted breeding efforts that have introgressed specific resistance genes (Ph-1, Ph-2, Ph-3, and Ph-5) (Foolad et al, 2008;Gardner and Panthee, 2010;Panthee and Gardner, 2010).…”

“…Just after transplanting, plants were watered with 15:15:15 solution (15% nitrogen, 15% phosphorus and 15% potassium) during 30 min adding-up a volume of 4 l per plant. During the course of the experiment, watering consisted of 30 min of water twice in a week (Mondays and Fridays) [ 41 ]. At harvest, the soil attached to the main and secondary roots was taken by shaking, placed in separate plastic bags, and kept at 4 °C.…”

“…‘Moneymaker’ (MM). The clonal population was established from an individual gravid female coming from an infested tomato field (in Aranjuez, Spain); aphids were reared on tomato plants inside insect‐proof cages (46.5 × 46.5 × 46.5 cm) in a climatic chamber at 22–25 °C 65% of relative humidity (HR) and a L16:D8 photoperiod 25 . Plants were watered twice a week.…”

“…Cultivated tomato shows in general low levels of anti‐herbivore substances (acylsugars among others) compared with wild relatives, making them more susceptible to a wide range of pests 12,25 . However, traditional breeding techniques allow the introgression of defensive traits from wild relatives into cultivated tomato.…”
