SCR-22 of pollen-dominant S haplotype class is recessive to SCR-44 of pollen-recessive S haplotype class in Brassica rapa
SCR-22 pollen-dominant S haplotype SCR-44 Brassica rapa
2023/8/9
SCR/SP11 encodes the male determinant of recognition specificity of self-incompatibility (SI) in Brassica species and is sporophytically expressed in the anther tapetum. Based on dominance relationshi...
Recent advances in genomic technologies have generated a large number of expressed sequence tags (ESTs) in cotton. Many of these ESTs are available in public databases, which offer an opportunity to i...
A molecular analysis of class III peroxidases from cotton (Gossypium hirsutum L.) was undertaken using the sequence of 12 genes available in databanks. Sequence comparison, phylogenetical analysis, an...
用两个马铃薯栽培品种"鄂马铃薯3号"和"甘农薯2号"的试管薯为供体材料,建立了一种农杆菌介导的简单、快速和高效的遗传转化系统.在含有75 mg/L卡那霉素的选择培养基上,2～3周可产生抗性芽,4～5周获得完整的转基因植株.筛选出了试管薯遗传转化的优化条件,特别是在再生培养基中加入2 mg/L玉米素,两个品种的转化频率分别高达45.5%和43.9%.周期短(4～5周)、一步培养和转化频率高,使该转化...
将正反义classⅠpatatin基因导入马铃薯品种甘农薯2号中，有2个转正义基因株系试管块茎的可溶性蛋白含量和LAH活性与对照相比有不同程度的增加，有3个转反义基因株系的可溶性蛋白质含量下降，并且所有转反义基因植株的LAH活性都不同程度地降低。试管块茎的诱导结果表明，有1个转正义基因株系的结薯株率和单株结薯数比其对照明显增加，有2个转反义基因株系的结薯株率和单株结薯数比对照明显减少。这些实验结果...
