The dataset contains 11 columns, described below.

date = date that the leaf was surveyed for infection

Tiller = tiller number on the plant (for some plants, the original tiller had to be replaced)

ID = Plant ID number.

Endophyte = Infection status of the seed by the fungal endophyte, Epichloë coenophiala.

Leaf = Leaf number, indicating the relative age of each leaf on a tiller, with lower numbers corresponding to older leaves.

LeafID = a unique ID for each leaf (combination of ID, Tiller, and Leaf).

cohort = The experimental cohort the plant ID belongs to. There were three cohorts. The first cohort was placed on 22 June 2015, during the Colletotrichum epidemic, but before other parasite epidemics began. The second cohort was placed on 27 July 2015, shortly after the start of the Rhizoctonia epidemic, but before the Puccinia epidemic began. The third cohort was placed on 21 September 2015, shortly after the start of the Puccinia epidemic, when all three parasites were present.

leaf.emergence = the date that each leaf emerged. For leaves that emerged before the start of the experiment, this date was set to the date that the plant was placed in the field.

Puccinia, Colletotrichum, Rhizoctonia = the percent leaf area damaged by Puccinia, Colletotrichum, and Rhizoctonia, respectively. This is a measurement of infection severity.
