Generation of XA27-tagged lines. A, Disease phenotypes of XA27-tagged lines, control lines, and wild-type plants at 14 DAI with X. oryzae pv oryzae strains. Plants were inoculated with X. oryzae pv oryzae PXO99A harboring wild-type avrXa27 or avrXa27 mutant PXO99AME1 (ME1), and photographs were taken at 14 DAI. IRBB27, wild-type Xa27 plants; Ni, Nipponbare; GFP, L8 of PUbi:GFP:TNos; XA27-GFP(L22), L22 of PXa27:XA27-GFP:TXa27; XA27-GFP(L9), L9 of PUbi:XA27-GFP:TNos; XA27G-GFP, L18G of PUbi:XA27G-GFP:TNos; XA27-FLAG, L18F of PXa27:XA27-FLAG:TXa27. B, Expression of PXa27:XA27-GFP:TXa27 in uninoculated (UI) L22 plants or L22 plants at 3 DAI with X. oryzae pv oryzae strains PXO99AME1(ME1) and PXO99A. Nipponbare (Ni) was used as a control. C, Ubiquitin promoter-driven GFP, XA27-GFP, and XA27G-GFP gene expression in transgenic lines. GFP, L8 of PUbi:GFP:TNos; XA27-GFP(L9), L9 of PUbi:XA27-GFP:TNos; XA27G-GFP, L18G of PUbi:XA27G-GFP:TNos. Nipponbare (Ni) was used as a control. D, Expression of PXa27:XA27-FLAG:TXa27 in uninoculated (UI) L18F plants or L18F plants at 3 DAI with PXO99AME1(ME1) or PXO99A. Nipponbare (Ni) was used as a control. E, Expression of XA27-FLAG in uninoculated (UI) L18F plants or L18F plants at 3 DAI with PXO99AME1(ME1) or PXO99A. Nipponbare (Ni) was used as a control. XA27-FLAG was detected with anti-FLAG monoclonal antibodies. The molecular mass values of standard protein markers (Amersham Biosciences; RPN755) are shown in kilodaltons. The position of XA27-FLAG is indicated (arrowhead).
