The root-hypocotyl tissues of infested autumn squash seedlings
grown in infested soil showed a healthy appearance after
30 days (Fig. 3 a).
A slightly suberised layer was observed in the epidermis by day 42

cucurbitacearum infection, since in the soil-growing plants
symptoms developed earlier and were more intense in this species
than in autumn squash (Figs. 2 and 3 ).
Under the relatively mild infection conditions we used in the
potted plant experiment, the autumn squash seedlings showed only
modest suberin deposition in the cells beneath the epidermis after
42 days in culture (Fig. 3 ), which demonstrates slower
fungal colonisation than in muskmelon.
