Identification of candidate genes for key fibre-related QTLs and derivation of favourable alleles in Gossypium hirsutum recombinant inbred lines with G. barbadense introgressions
海岛棉 基因组组分 遗传作图群体
2024/5/17
该研究以渗入了海岛棉基因组组分的优质种质鲁原343为亲本,构建了包含239个重组自交系的遗传作图群体,利用SLAF标签构建了高密度遗传图谱,结合7个环境的表型数据,共鉴定104个纤维品质和产量性状QTLs,其中66个QTL共定位于19个QTL簇中。该研究团队通过进一步对鲁原343进行全基因组深度测序,解析鲁原343的遗传组成及其对纤维相关性状的遗传贡献,发现来自G. hirsutum races(...

以一个耐盐的二倍体野生种旱地棉和对盐敏感的陆地棉栽培种苏棉12号为材料,运用cDNA-AFLP技术,比较两个材料分别在盐胁迫前后的表达情况,获得了25个仅在旱地棉盐胁迫下特异表达的转录片段(TDF)。将这些片段进行电子克隆,延伸后的序列进行BLAST分析,结果显示23个转录片段推断的氨基酸序列与已知的蛋白同源,这些盐诱导表达的基因主要涉及离子转运、活性氧清除、细胞信号传导、细胞分裂、转录调节、膜保...
Evaluating host plant resistance in cotton (Gossypium hirsutum L.) with varying gland densities to tobacco budworm (Heliothis virescens F.) and bollworm (Helicoverpa zea Boddie) in the field and laboratory
Cotton Gossypol Helicoverpa Heliothis Terpenoid Aldehydes

Cotton (Gossypium hirsutum L.) produces a number of toxic terpenoid aldehyde (TA) compounds contained in epidermal glands that help protect the plant from pests and diseases. In the seed, one of these...
于2008~2009年在长江流域下游棉区,选用纤维比强度差异明显的德夏棉1号(平均比强度26.2 cN/tex)、科棉1号(平均比强度35 cN/tex)和美棉33B(平均比强度32 cN/tex)为试验材料,设置不同施氮量以形成不同的棉铃对位叶氮浓度,研究了棉铃对位叶氮浓度对纤维发育过程中关键酶(蔗糖酶、蔗糖合成酶、磷酸蔗糖合成酶、β-1, 3-葡聚糖酶)活性及纤维比强度形成的影响。结果表明,棉...
为兼顾试验的重复性和生态区域性,选用高品质棉(科棉1号)和常规棉(美棉33B)品种为材料,于2005年分别在江苏南京(118o50′E, 32o02′N,长江流域下游棉区)和江苏徐州(117°11′E, 34°15′N,黄河流域黄淮棉区)设置施氮量(低氮:N 0 kg/hm2;适氮:N 240 kg/hm2;高氮:N 480 kg/hm2)试验,研究施氮量对不同开花期棉铃纤维细度、成熟度和马克隆值...
以棉纤维比强度高的科棉1号、比强度中等的美棉33B 2个品种为材料,于2006-2007年在江苏南京设置大田分期播种试验,使棉铃发育处于不同温度条件,于棉株7~9果枝第1、2果节棉铃开花时喷施6-苄基腺嘌呤(6BA)和脱落酸(ABA),研究不同的铃期日均最低气温条件下6-BA和ABA对棉花产量和纤维品质的影响。结果表明:由晚播造成的低温降低了棉花产量及纤维品质。外施6-BA、ABA对棉株中部果枝铃...
