Fig 7. Resistance of Hm1^A seedlings to CCR1 is increased by extended photoperiod.

Two-week-old homozygous Hm1^A seedlings were inoculated with CCR1 and incubated under two different photoperiods of 12 h daylight (12 h L:12 h D) and 18 h daylight (18 h L:6 h D). Hm1^A seedlings grown under 12 h daylight were susceptible to CCR1 at 72 hpi (A) and 96 hpi (B). Hm1^A seedlings incubated under the extended photoperiod of 18 h light exhibited notably enhanced resistance at both 72 hpi (C) and 96 hpi (D).
