这样，现代汉诗的发生首先就牵涉到与中国知识分子的现代性宏伟目标、与汉语、与"诗打的观念、与西方语言特征的复杂关系。但诗歌作为一种特殊的言说，它的"发生"又是在个体经验、诗歌语言和特定的艺术形式之间展开的。这样，当我们辨析从晚清至"五四以来的诗歌文本，就会发现古典诗与现代诗在经验、语言和形式之间冲突与互动的丰富形态。

The identification and study of the control factors that regulate gene expression at different stages are of great value to elucidate the mechanism of spermatogenesis and spermiogenesis. Such study can also provide foundation and cues to investigating the mechanism of infertility and immunological contraception.

作为体内高度分化的雄性生殖细胞，精子发生过程中经历了从形态到生化的复杂变化，在这一过程中有一系列的特定基因按严格的时空顺序转录和翻译，因此寻找和研究不同发育阶段的差异表达的基因，将有助于最终阐明精子发生的机理，并为控制生育和不育机理的探索提供新的线索。

The results were:The main morphological difference were that the color of squama, median fascia, reniform stigma, orbicular stigma, the part between postmedian fascia and subterminal fascial and terminal hair on forewings, hindwings, terminal hair on hindwings, and the color of skin under squama on obdomen were black, and the color of pupa was also black, and the color of hair on dorsal thorax and obdomen were white.

2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.

文章综述了植物2n配子发生及其遗传标记研究现状，论述涉及有关形态学标记、细胞学标记、同工酶标记乃至DNA标记等遗传标记在2n配子研究中的应用，指出通过花粉形态观察、大小孢子母细胞减数分裂行为观察、杂种后代倍性鉴定以及亲子分子标记相关分析等，对2n配子发生、2n配子遗传类型与杂合性以及2n配子在育种实践中的有效性等进行研究。
