查询词典 markers

In this study, AFLP markers for YrSp gene were identified and SCAR markers were developed using the near-isogenic line YrSp/6 x Avocet S and its susceptible parent Avocet S as materials with the YrSp gene donor parent Spaldings Prolific as control. The main results were given as follows:1. A total of 225 primer combinations were used in AFLP analysis of the materials YrSp/6×Avocet S, Avocet S and Spaldings Prolific.

In each case, only one of the two possible expected ratios was accepted in all markers, furthermore, no significant deviation from Mendelian inheritance (two-tailed binomial test, P≥0.053). To investigate the polymorphism of AFLP markers, and the genetic diversity in populations of H. discus hannai, eight abalone populations were analyzed by using a total of six AFLP primer combinations. The mean percentages of polymorphic loci of the eight populations were 48.65%, 50.50%, 51.17%, 50.51%, 58.90%, 60.07%, 68.92% and 54.05%, respectively.

皱纹盘鲍群体多样性研究中，选取的6对AFLP引物组合在8个皱纹盘鲍群体内均能扩增出清晰、可重复的扩增产物，扩增带型差异明显。8个群体的多态位点比率分别为：大连养殖群体48.65%、烟台养殖群体50.50%、青岛胶南养殖群体51.17%、青岛崂山养殖群体50.51%、山东长岛野生群体58.90%、山东俚岛野生群体60.07%、日本岩手野生群体68.92%、大连野生群体54.05%；预期杂和度分别为0.2291、0.2438、0.2442、0.2374、0.2626、0.2723、0.3137和0.2802。

为了解东方亚种濒危的现状并为制定科学、有效的保护措施提供科学依据，本研究利用核微卫星DNA和mtDNA控制区序列，从父系和母系两方面对大鸨东方亚种的遗传多样性进行了研究。

The result is stored in the temporary storage unit and is output to the screen by the subprogram "Character generator output". The subprogram "Marker" holds the markers fixed in position in the event of output exceeding their allowable limits, and also handles clearing of the markers

结果被在临时存储单位中储藏和被子程序"个性发电机从输出到"向屏幕使出。，打记号的人把子程序"打记号的人"着力点固定在如果发生在上超过他们的容许极限和也柄的从输出到位置上打记号的人的清除

Typical bands were used to analyze relation with ecotypes and characters of fruits, indicating that there was no relation between typical bands and ecotypes, but some extent relation between bands and characters of fruits existed. If all cultivars were divided into freestone and clingstone, melting and nonmelting, both freestone (ratio shared total survey, 41/56=73.2%) and clingstone (ratio shared total survey, 33/79=41.8%) appeared in the loci of S_(167)-1050 bp linked marker raised by Warburton et al. It was apparently not strong linkage between the marker and the character, and exchange rate of genes was high. If combinations of S_(167)-850bp and S_(167)-1050bp or S_(167)-850bp and S_(167)-1400bp were used to distinguish characters of fruits, 6 freestone accessions without clingstone ones and 6 melting accessions without nonmelting ones displayed in the first combination of markers, 20 clingstone accessions and 2 semi-freestone ones without freestone ones appeared in the second combination of markers.

通过典型带对不同生态型、果实性状为类别进行分析，结果未发现有与生态型相吻合的特征带出现，而将供试所有品种按离核、粘核和溶质、不溶质划分归类，供试品种在Warburton等得到S_(167)-1050 bp处粘离核分子标记，出现既有离核(占供试离核41／56=73.2％)，又有粘核(占供试粘核33／79=41.8％)，可见此连锁标记连锁性不强，发生交换的机率较高，而S_(167)-850bp带和S_(167)-1050bp带同时出现时，该组包含6个离核，无粘核品种；6个溶质，而无不溶质。S_(167)-850bp和S_(167)-1400bp同时出现时，包含20个粘核品种和2个半离核品种。
