单倍体植株 meaning in English
haplobiont
Examples
- Embryological studies reveal that megaspore and such cells as egg , synergid and antipodals in mature embryo sac initiate the division of forming haploid plants through embryogenesis or callus formation
胚胎学观察揭示大孢子与胚囊内的卵细胞、助细胞和反足细胞均有可能在培养中启动分裂，通过胚状体或愈伤组织形成单倍体植株。 - Anther culture ( pollen culture ) the generation of haploid plants from immature pollen grains or intact excised anthers . the resultant plants are generally smaller than their diploid counterparts
花药培养：从未成熟的花粉粒或者切下的完整的花药中再生出单倍体植株的过程。这样培养出来的单倍体植株通常比正常培养出的二倍体植株小。 - This review includes the following subjects : induction frequency of haploids depend on genotypes , developmental stage of explants , temperature pretreatment of the explants , medium composition and the conditions of cultivation
迄今己有9个科21种植物用这一方法诱导出单倍体植株，植物的基因型、外植体的发育程度、接种前的预处理、培养基和培养条件等均能影响诱导率的高低。 - Choline dehydrogenase ( cdh ) isolated from escherichia coli , can help the expression of glycine betaine efficiently . to get some salt - tolerant plants , the cdh gene , mediated by agrobacterium , was transformed to the haploid of populus simoniixp . nigra
本实验以农杆菌( agrobacteriumtumefaciens )为介导进行遗传转化，将编码cdh的耐盐基因( bet - a )导入小黑杨( populussimonii p . nigra )单倍体植株( haploid )的基因组内，以期获得耐盐植株。
