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...
QTL Mapping for Leaf Area of Tea Plants (Camellia sinensis) Based on a High-Quality Genetic Map Constructed by Whole Genome Resequencing

The cultivated apple is one of the most common and important fruit crops in temperate regions. Phylogenetic analysis using a wide array of apple genotypes could give insights into the origin and domes...
Genome induced mutation in Callistephus chinensis Ness. – evaluation of plant fertility and seed characteristics
Callistephus chinensis China aster polyploidy
2015/1/21
Thousand seed weight (TSW, g), achene size (mm) and fertility were evaluated in polyploid plants of C0 (1999) and C1 (2000) generations. The fertility of polyploid plants was usually very low (more th...
Preparation of Microprotoplasts for Partial Genome Transfer via Microprotoplast Fusion in Liliaceous Ornamental Plants
cell suspension culture Hemerocallis hybrida Lilium longiflorum micronucleation microsporocyte
2009/9/10
We aimed to produce intergeneric hybrid plants with only one or a few alien chromosomes via microprotoplast fusion for genetic improvement and chromosome studies in Liliaceous ornamental plants. In or...
Preliminary Results on Genome Mapping of an Italia x Mercan Grapevine Population
Grape genetic map linkage analysis QTL RAPD
2009/1/12
This research was conducted to construct genetic linkage maps of Vitis (2n = 38) from grape populations (60 F1 + 2 parents) of crossing of Italia and Mercan (Vitis vinifera L.) cultivars. RAPD reactio...
