Function
1.OsBBI1 modulates broad-spectrum resistance to blast fungus by modifying cell wall defence responses. Disease lesions on the osbbi1 leaves were significantly larger than on the WT leaves after inoculation with two races of M. oryzae. These results indicate that OsBBI1 is required for full immunity in rice against M. oryzae.
2.The functional characterization of OsBBI1 provides insight into the E3 ligase-mediated innate immunity, and a practical tool for constructing broad-spectrum resistance against the most destructive disease in rice. The level of protein ubiquitination increased with incubation time, indicating the E3 ligase activity of His-OsBBI1 (Figure 7B). In the presence of Ubi, E1, and E2 enzymes, His-OsBBI1 could carry out self-ubiquitination, while no clear protein ubiquitination was detected in the absence of E1, E2, or HisOsBBI1 (Figure 7C). The truncated mutant, OsBBI1 ∆RING ligase, and the RING domain in OsBBI1 is essential to its E3 Ubi ligase activity.
3.Enhancement of cell wall defence response in OsBBI1 overexpression plants The percentages of autofluorescent cell walls and cross-linking increased by ~10% in the OsBBI1-OE plants compared with that in the WT plants at 24 h.p.i. This increase was much more significant at 48 h.p.i. (Figure 5B and 5D). In contrast, the percentages of autofluorescent cell walls and cross-linking of wall-associated proteins at infection sites were lower in the osbbi1 plants than those in the WT plants at 24 and 48 h.p.i. (Figure 5E and 5F).
