Extended Data Fig. 2: Expression of SBRR1 in four SBRR-S or SBRR1-R varieties and ShB resistance of T-DNA insertion mutant sbrr1.
From: Natural variation in SBRR1 shows high potential for sheath blight resistance breeding in rice
a, Differences in the promoter region of SBRR1 among Dongjin, TG394, XD3 (Xudao 3) and YSBR1. ATG represents the start codon. b, Comparison of SBRR1 expression among the four varieties before and after R. solani inoculation (n = 3). c, T-DNA insertion site in sbrr1. P1, P2, and P3 indicate primers used for verification of the insertion. RB (right border) and LB (left border) indicate the right and left borders of T-DNA, respectively. d, PCR verification of the insertion site. e, Comparison of ShB severity between sbrr1 and WT in the field. Data in b and e are presented as means ± s.d. Statistical significances in b and e were determined by a two-sided Student’s t test. Scale bar, 10 cm.
