The asparagus genome sheds light on the origin and evolution of a young Y chromosome
雄性双倍体 芦笋 石刁柏 基因组测序
2023/3/31
该成果为江西省农业科学院牵头，与美国乔治亚大学和华大基因等联合，对雄性双倍体（YY）芦笋（石刁柏）进行全基因组测序，利用Illumina（二代）+PacBio（三代）+BioNano（基因组拼接系统）等多种技术手段组装，得到芦笋（石刁柏）基因组大小约为1.3Gb，有27,656个蛋白编码基因被预测。通过对石刁柏参考基因组的比较组学及实验分析发现，单独但相互关联的基因负责性别决定。性染色体在细胞遗传...
