From: Phytophthora capsici-tomato interaction features dramatic shifts in gene expression associated with a hemi-biotrophic lifestyle

Figure 1

Phytophthora capsici infection of tomato features a hemi-biotrophic lifecycle. (A) Tomato leaves infected with zoospore suspensions of P. capsici at 2-4, 8, 24, 48, and 72 hours post-infection (hpi). (B) Confocal microscopy images of tomato leaves infected with a transgenic P. capsici strain expressing the fluorescent protein TdTomato (red). Infection featured rapid germination of cysts and infection at 8 hpi, formation of biotrophy associated haustoria (arrowheads) visible up to 48 hpi after infection, and rapid growth and sporulation at 48 and 72 hpi respectively. Scale bar = 20 μm.
