| 1 | Identification of a novel seed size associated locus SW9-1 in soybean显示文摘Seed size is one of the vital traits determining seed appearance, quality, and yield. Untangling the genetic mechanisms regulating soybean 100-seed weight (100-SW), seed length and seed width across environments may provide a theoretical basis for improving seed yield. However, there are few reports related to QTL mapping of 100-SW across multiple ecological regions. In this study, 21 loci associated with seed size traits were identified using a genome-wide association of 5361 single nucleotide polymorphisms (SNPs) across three ecoregions in China, which could explain 8.12%–14.25% of the phenotypic variance respectively. A new locus, named as SW9-1 on chromosome 9 that explained 10.05%–10.93% of the seed weight variance was found significantly related to seed size traits, and was not previously reported. The selection effect analysis showed that SW9-1 locus has a relatively high phenotypic effect (13.67) on 100-SW, with a greater contribution by the accessions with bigger seeds (3.69) than the accessions with small seeds (1.66). Increases in seed weight were accompanied by increases in the frequency of SW9-1T allele, with >90% of the bred varieties with a 100-SW >30 g carrying SW9-1T. Analysis of SW9-1 allelic variation in additional soybean accessions showed that SW9-1T allele accounting for 13.83% of the wild accessions, while in 46.55% and 51.57% of the landraces and bred accessions, respectively, this results indicating that the SW9-1 locus has been subjected to artificial selection during the early stages of soybean breeding, especially the utilization of SW9-1T in edamame for big seed. These results suggest that SW9-1 is a novel and reliable locus associated with seed size traits, and might have an important implication for increasing soybean seed weight in molecular design breeding. Cloning this locus in future may provide new insights into the genetic mechanisms underlying soybean seed size traits. | Jiajia Li Jinghui Zhao Yinghui Li Yali Gao Sunan Hua Muhammad Nadeem Genlou Sun Wenming Zhang Jinfeng Hou Xiaobo Wang Lijuan Qiu | 2019 | The Crop Journal2019，7，4： | 4 |
| 2 | Comparison of gene flow among species that occur within the same geographic locations versus gene flow among populations within species reveals introgression among several Elymus species显示文摘当许多 taxa 在期间并且在种形成以后继续了基因流动,在进化生物学的挑战之一是与不完全的繁殖隔离理解种形成的进化。在 sympatric 和在各区发生的人口之间的人口结构的比较能揭示特定的基因渗入并且决定基因渗入是否以一种单向性或双向的方式发生。简单顺序重复标记被用来描绘 sympatric 和植物种类的在各区发生的人口结构, Elymus alaskanus (Scribn。并且 Merr ) Löve, E。caninus L. , E。fibrosus (Schrenk ) Tzvel,和 E。mutabilis (Drobov ) Tzvelev。我们的结果显示出那基因差异(H 在种类水平的 E ) 是 E。caninus (0.5355 )> E。alaskanus (0.4511 )> E。fibrosus (0.3924 )> E。mutabilis (0.3764 ) ,建议那 E。caninus 和 E。alaskanus 比 E 更可变。fibrosus 和 E。mutabilis。在发生在一样的地理地点以内的种类之间的基因流动对在在种类以内的人口之间的基因流动与相比提供基因渗入的证据。我们的结果显示了在种类之间的那基因流动发生在一样的地理地点以内比在在种类以内的人口之间,建议源于 introgressive 杂交的那基因流动可能发生在这些的 sympatric 人口之中的高种类,并且可以在基因差异划分在之中并且在人口以内起一个重要作用。从 E 的迁居率。fibrosus 到 E。(0.2631 ) mutabilis 最高在四种之中被学习。在四种之中的基因流动的不均匀的率也被观察。调查结果热点这四 Elymus 种的复杂进化。 | Pan-Pan Wu Hong-Wei Zuo Genlou Sun De-Xiang Wu Bjorn Salomon Qun-Wen Hu Zhao-Rong Dong | 2016 | Journal of Systematics and Evolution2016，54，2： | 3 |
