Figure S4. (a) The number of OsAP79 knockout plants
generated by CRISPR/Cas9 system. (b) The mutation information of two
independent OsAP79 knockout lines. Arrows label the target sites.
Red box indicated the 1bp deletion or 1bp insertion.
Figure S5. (a) Seedling survival rate of overexpressed (OE)
T0 lines of OsAP79 . (b) Relative expression ofOsAP79 in OE T0 lines. (c) Seedling survival rate
of OE T1 lines of OsAP79 . (d) Seedling survival
rate of knockout T0 lines of OsAP79 . Asterisks in
(a-d) represent significant differences based on one-way ANOVA and Tukey
test (*, P < 0.05; **, P < 0.01).
Figure S6. Rice protoplasts were transfected with OsAP79-GFP.
The transfected cells were examined under a confocal microscope. The
images were then processed using ZEISS ZEN confocal microscope software.
Overlapping fluorescence signals show that OsAP79 localizes to the
endoplasmic reticulum (ER). Bright-field images are shown on the right.
Scale bars, 10μm.
Figure S7. Principal component analysis (PCA) scores plots rice
leaf sheath metabolites associated with BPH infestation. Metabolites of
overexpression (OE) (a) or knockout (c) and Nipponbare (NIP) infested
with BPH for 0 h (control), 48 h and 72 h. Metabolites of OE (b) or
knockout (d) and NIP infested with BPH.
Figure S8. PLS-DA score plots and loading plots of rice leaf
sheath and metabolites. Overexpression (OE) line of OsAP79 (a),
knockout line of OsAP79 (c), and Nipponbare (NIP) (e). PLS-DA
score plots obtained from metabolic profiles of leaf sheaths of OE line
with BPH treatments for 0 h (control), 48 h and 72 h, symbols filled
circles OE line with BPH treatments for 0 h, filled squares OE line with
BPH treatments for 48 h, filled triangle OE line with BPH treatments for
72 h. Metabolites of PLS-DA loading plot OE line of OsAP79 (b),
knockout line of OsAP79 (d) and NIP (f).
Figure S9. (a) Nipponbare (NIP), overexpression (OE) and
knockout (CR) lines were applied to Xoc infestation. Scale bars,
5cm. (b) NIP, OE and CR lines were applied to Xoo infestation.
Scale bars, 1cm. Lesion length detection after Xoc (c) andXoo (d) infestation. Asterisks in (c,d) represent significant
differences based on one-way ANOVA and Tukey test (*, P< 0.05; **, P < 0.01).
Figure S10. (a) Seedling survival rate after cold tolerance
treatment.. (b) Nipponbare (NIP), overexpression (OE) and knockout lines
were treated at 5 °C for 5 days and recovered at room temperature (25
°C) for 7 days. Scale bars, 5cm.
