栽培陆地棉 纤维品质 优异位点 分子育种
2024/4/16
栽培陆地棉广泛种植于世界各地，是最重要的天然纤维来源，纤维品质直接决定了其经济价值。国内外棉花育种家开展了广泛的远缘杂交工作，将许多稀有的重要基因转移到栽培陆地棉中提高纤维品质，但并未对这些基因进行深入研究。本研究分析了超过3000份棉花种质资源，总计调查了近80000个纤维品质数据，全面剖析和评估了现存陆地棉种质资源中纤维品质相关的优异位点，并从远缘杂交渐渗系中鉴定到两个新的与纤维品质密切关联的...
髓母细胞瘤是儿童最常见的颅脑恶性胚胎性肿瘤，世界范围的发病率为每年5.07-6.8/10万人，是引起儿童肿瘤相关死亡的首要原因。目前针对髓母细胞瘤的治疗是一种联合治疗的策略，手术为主，综合放疗以及化疗、靶向药物治疗等作为辅助治疗。髓母细胞瘤的发病机理极其复杂，涉及表观遗传学、胚胎发育学等多个方面，目前尚未完全明确，导致总体治疗效果并不是非常理想。
