Time-course of the phenotypic response of the 1st and 3rd B. juncea leaf to A. brassicicola infection. Plants were grown and infected under different day-length regimes, simultaneously: (a,e,i) 8 h day/16 h night; (b,f,j) 12 h day/12 h night; (c,g,k) 16 h day/8 h night; and (d,h,l) continuous light, examined 24 (a–d), 48 (e–h), and 72 (i–l) hours post-inoculation (hpi). The presented images were taken in a single experiment. The 1st leaf is the oldest. Scale bar = 20 mm.
