Fig. 3. Verticillium dahliae infection process in A, cotton and B, maize roots after inoculation. The infection process comparison after inoculation of V. dahliae strain Vd991 on cotton (Gossypium hirsutum cv. Junmian No. 1) and maize (Zea mays cv. Xianyu 335) roots at 2, 5, 7, and 10 days postinoculation using transmission electron microscopy. Three-week-old cotton and maize seedlings were inoculated with conidial suspensions (1 × 107 conidia/ml) of V. dahliae and were planted into sterile soil. Bars = 100 μm. Ep, epidermis; Co, cortex; Xy, xylem. Red arrowheads indicate the conidia or mycelia in the cotton or maize xylem.
Xin-Xin Liu et al. provide new clues on the sequence of events that occur when #Verticillium dahliae infects monocots versus dicots and may underlie Verticillium wilt symptoms on dicots but not on monocots. Learn more: https://doi.org/10.1094/PDIS-01-25-0114-SC
