结果表明除SDS法外,其余两种方法均可获得完整的海带基因组DNA,RAPD扩增谱带清晰稳定。 尤以改良CTAB法提取的DNA质量较好。

Haplobiontic Describing life cycles in which only one type of somatic body is formed, which may be either haploid or diploid, i.e. either the sporophyte or the gametophyte generation is missing.

单型世代:生活史中仅有一种生活的单倍体或二倍体的植物体,也就是说其孢子体或配子体世代缺失了。

To obtain the active thylakoid membranes of sporophyte and gametophyte,three different buffers are used: 20mM Mes-Na (pH6.4) ,30mM Naphosphate buffer(pH7.0), 50mM Hepes buffer(pH7.8).
