1Root and shoot traits responses to phosphorus deficiency and QTL analysis at seedling stage using introgression lines of rice显示文摘Phosphorous(P) deficiency is a major restraint factor for crop production and plants have developed several mechanisms to adapt to low P stress.In this study,a set of 271 introgression lines(ILs) were used to characterize the responses of seedlings to low P availability and to identify QTLs for root traits,biomass,and plant height under P-deficiency and P-sufficiency conditions.Plant height,total dry weight,shoot dry weight,and root number were inhibited under P-deficiency,whereas maximum root length(MRL) and root-shoot ratio(RS) were induced by P-deficiency stress.Relative MRL(RMRL,the ratio of MRL under P-deficiency to MRL under P-sufficiency con-dition) and relative RS(RRS) were used to evaluate P-deficiency tolerance at the seedling stage.A total of 24 additive QTLs and 29 pairs of epistatic QTLs were detected,but only qRN4 was detected in both conditions.This suggested that different mechanisms may exist in both P supply levels.QTLs for adaptive traits(RMRL,RRS,RRV,and RRDW) and qRN4 consistently expressed to increase trait stabil-ity may contribute to P-deficiency tolerance.Twelve intervals were cluster regions of QTLs for P-deficiency tolerance,and one QTL(qRRS8) showed pleiotropic effects on P-deficiency tolerance and drought tolerance.These interesting QTLs can be used in marker-assisted breeding through the target ILs.Junzhou Li Yan Xie Anyong Dai Lifeng Liu Zichao Li 2009Journal of Genetics and Genomics2009,36,3:12
2Development of upland rice introgression lines and identification of QTLs for basal root thickness under different water regimes显示文摘基因渗入线(IL ) 是为识别量的特点 loci (QTL ) 的珍贵材料,评估帮助的基因相互作用,和标记繁殖。包含的一套 430 IL (BC5F3 ) 在一块低地从高地分割热带装饰用的梨树栽培变种 IRAT109 适度的装饰用的梨树栽培变种 Yuefu 背景被开发。176 个多态的标记被用来识别 introgressed 片断。从 IRAT109 的片断都没在 160 根线被发现。另外的 270 根线的 Introgressed 片断盖住 99.1% 施主染色体。introgressed 施主片断的吝啬的数字与 14.4 厘米的平均长度每个人是 3.3。QTL 分析在在灌溉低地,高地和水耕法的条件下面种的 270 IL 的基础根厚度(BRT ) 上被进行。影响 BRT 的 22 QTL 的一个总数被识别,六 QTL (qBRT3.1, qBRT3.2, qBRT6.1, qBRT8.2, qBRT9.1,和 qBRT9.2 ) 一致地在至少二环境(地点和水政体) 下面被表示,并且 qBRT7.2 是在低地条件下面识别的新 BRT QTL。包含 qBRT9.1 的 IL255 在栽培变种 Yuefu 上看了 10.09% 和 7.07% BRT 的增加什么时候分别地在高地和低地条件下面成长。用 304 根 F2:3 线的一张人口源于生气 IL255 ??????? 瑡歭?? 匠 ? 彋 ????????? 僚 ?? 传敶敲灸敲獳潩吗??Junzhou Li Deping Wang Yan Xie Hongliang Zhang Guanglong Hu Jinjie Li Anyong Dai Lifeng Liu Zichao Li 2011Journal of Genetics and Genomics2011,38,11:3
