No If yes, name of file(s) that was updated: Why was the file updated? When was the file updated? METHODOLOGICAL INFORMATION Description of methods used for collection/generation of data: Seeds of winter wheat (var. Julius) were treated with chemical elicitors methyl salicylate, methyl jasmonate or cis.jasmone with method based on (Kraus et al 2019 doi:10.1371/journal.pone.0222800) Aphid plant colonization: Ten aphids (Rhopalosiphum padi) were placed onto wheat plants (treated with elicitors or water control) at 2-leaf stage and the number of aphids settled on the plants after 2 hours was recorded, using method based on (Glinwood et al 2009 DOI 10.1007/s11829-009-9072-9) Aphid population development: One adult aphid (Rhopalosiphum padi) was placed onto wheat plants (treated with elicitors or water control) and after it had produced nymphs, all but one nymph were removed. The number of days for each nymph to become adult and produce a first nymph (d) was recorded and the number of nymphs produced in a time equal to d (M) was recorded. The intrinsic rate of aphid population increase (Rm) was calculated using the formula Rm=0.74(LnM)/d (Wyatt & White 1977 doi.org/10.2307/2402807) Methods for processing the data: Instrument- or software-specific information needed to interpret the data: Standards and calibration information, if appropriate: Environmental/experimental conditions: glasshouse/growth chamber Describe any quality-assurance procedures performed on the data: People involved with sample collection, processing, analysis and/or submission: Robert Glinwood DATA-SPECIFIC INFORMATION FOR: [Aphid population development] Number of variables: 7 Number of cases/rows: 171 Variable List: Treatment (Control, MeSa= methyl salicylaye, MeJa= methyl jasmonate, CJ= cis-jasmone), Concentration (concentration of elicitor mM millimolar), days to repr (d)= number of days between aphid birth and first reproduction no. offspring (M)= number of aphid offspring produced in time equivalent to d, no. offsring/day= M/d, Rm intrinsic rate of population increase calculated by Rm=0.74(LnM)/d Experiment code A= MeSa vs Control, B= MeJa vs Control, C= CJ vs Control Missing data codes: Specialized formats or other abbreviations used: DATA-SPECIFIC INFORMATION FOR: [Aphid plant colonization] Number of variables: 5 Number of cases/rows: 240 Variable List: Treatment (Control, MeSa= methyl salicylaye, MeJa= methyl jasmonate, CJ= cis-jasmone), Conc (concentration of elicitor mM millimolar), no. aphids settled after 2 hrs, Experiment code (indicates which control treatment to compare with which elicitor treatment) Missing data codes: Identical values may occur on more than one row so a unique data point identifier is included in Column 1 Specialized formats or other abbreviations used:
