AFLP analyses were carried out on Thatcher, 23 near-isogenic lines and F2 generation of TcLrl9 × Thatcher, to develop molecular markers for gene Lr19 resistance to wheat leaf rust. Seven markers linked to Lr19 resistance trait were obtained,which were P-AGT/M-GAG289 bp (3.3 cM), P-ACA/M-GGT102 bp (4.1 cM), P-ACA/M-GGT106 bp (4.1 cM), P-AAC/M-CAG123 bp(4.9 cM), P-AAC/M-GGT203 bp (5.0 cM), P-ACA/M-GGT290 bp (5.7 cM), and P-ATC/M-GAG293 bp (9.6 cM). All of these specific fragments were isolated from the polyacrylamide gels, reamplified, cloned, and sequenced. The research may facilitate genetic mapping, physical mapping, and the eventual cloning of Lr19.

门静脉性胆道病(portal ductopathy,PD)是指由于肝外门静脉阻塞(extrahepatic portal vein obstrction,EHPVO)导致胆囊和胆管出现解剖学、形态学异常和功能障碍的一种疾病[1-2].它可累及整个胆道系统,包括肝内外胆管、胆囊管和胆囊[2].EHPVO是导致门静脉高压的常见病因之一,长期EHPVO可导致门静脉侧支循环出现,并形成门静脉海绵样变性.研
