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。

The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4. Differentially expressed cDNA libraries of the stages of proembryo mass and somatic embryo maturation were successfully constructed by suppression subtractive hybridization.
对Y35体细胞胚胎发生过程中抗氧化酶活性变化的研究显示:(1)SOD活性在52.98~133.20 U·g-1·h-1之间,并在早期单胚形成后一直保持上升的趋势,表明其与胚性细胞的分化及体细胞胚的发育均具呈正相关;(2)POD活性在0.05~0.50 U·mg-1·min-1之间,呈现出先下降后升高的趋势,在胚性愈伤组织中最高,而在后期单胚形成时降至最低,表明其与原胚团的分裂和分化呈正相关,但与PEMⅢ向后期单胚的发育呈负相关;(3)CAT活性在0.86~2.81 U·mg-1·min-1之间,表现出升-降-升的变化趋势,在早期单胚形成时升至最高,在早期子叶胚形成时降至最低,表明其与早期单胚的发育呈正相关,而与中期单胚和早期子叶胚的发育呈负相关。

Cognitive enhancement therapy is described as an integrated approach to the enhancement of neurocognitive and social cognitive abilities, which attempts to capitalize on a presumed neuroplasticity reserve believed to respond to enriched cognitive experiences. It is used as a recovery-phase intervention for symptomatically stable schizophrenic outpatients who are socially and cognitively disabled despite reduced risk of relapse.

The results are as follow:The diploid chromosome number of Taihe Silkies was 2n=78,the basic number of chromosome arms was AF=90 and the sex chromosome type was ZZ/ZW.According to the measured relative length,arm ratio and centromeric index,the first 10 pairs of macro-chromosomes are described as follows:No.1 ,9 and Z,W chromosomes were metacentrics,No.2,4,7 were submetacentrics,and No.3,6,8,10 were telocentrics.Studies on Taihe Silkies′ G-band showed that the first 10 pairs of macro-chromosomes can be divided into 29 zones and 190 bands.
