FIGURE 1

Laser-capture microdissection (LCM) of C. campestris haustoria penetrating tomato stems at three developmental stages. (A–C) Toluidine blue O stained paraffin sections of tomato stem with C. campestris early (A), intermediate (B), and mature stage (C) haustoria. Red line indicates the interface between C. campestris and host tomato. Cc indicates C. campestris; Sl indicates S. lycopersicum. (D–F) C. campestris haustorial tissues and host tissues were collected using LCM. A paraffin section of an intermediate stage haustorium before collection (D), after haustorial tissue collection (E), and after host tissue collection (F). (A) and (C), scale bars = 250 μm. (B), (D), (E), and (F), scale bars = 100 μm. Part of this figure (A–C) is modified from one in a previously published paper Jhu et al., 2021 with new information added.
