查询词典 alien

Lines which were 2n=21"+1" and one line which was 2n=20"+2", one line which was 2n=43. The salt-resistance addition line Line15 was confirmed as a Disomic alien addition line by C-banding, SSR, FISH methods, and the two alien addition chromosomes had close correlation with the long arm of the second homoeologous group, the centromere region of the third homoeologous group and the short arm of the seventh homoeologous group. We also confirmed the particular C-banding type of the alien addition chromosomes by C-banding following FISH method. The drought-resistance addition line Line17 was found also as a Disomic alien addition line by SSR and FISH detection. The alien addition chromosomes had close correlation with the short arm of the second homoeologous group.

There were only three invasive alien plant species out of 24 investigated plant species occurred in core zone, which were clearly lower than those of experimental and buffer zones. The invasive alien plant species accounted for 12.5% of total plant species. The invasive alien plant species with the largest comprehensive values of dominance were Peperomia pellucida and Ageratum conyzoides.

The barley chromosome in wheat was identified by genomic in situ hybridization in which biotin labelled total genomic DNA of barley betzes was used as probe and the unlabelled total DNA of common wheat Chinese Spring as blocking DNA. A series of wheat materials were tested as follows; two disomic alien substitution and monosomic alien addition lines, 2n=43; two monosomic alien substitution lines.

用生物素(Biotin-16-dUTP)标记的大麦Betzes基因组DNA作探针，以普通小麦中国春总DNA作封阻进行基因组原位杂交(Genome in situ hybridiz ation，简称GISH)，从13株小麦-大麦杂交后代中鉴定出2个含有3条大麦B etzes2H染色体的材料(2n=43)；2个2H单体异代换系(2n=42)；7个2H二体异代换系(2n=42)。

Other three alien translocation lines referring to chromosome Lr.14 of L.racemosus were also induced via irradiated pollens.After irradiated by gamma raysof 1KR does,the pollens of T.aestivum-L.racemosus Lr.14 disomic addition lineswere used to pollinate wheat varieties"Yangmai No.5"and"Mianyang No.11".M1plants have pairing between wheat chromosomes and Lr.14 ofL.racemosus at PMCMI stage were self-pollinated,and the M2 seeds used to be Giemsa C-banded andfluorescence in situ hybridized.As the result,three alien translocation lines wereobtained and T12 was observed to have distal translocation chromosomes betweenLr.14S and a wheat chromosome segment(TW-Lr.14S·Lr.14L).T13 wasidentified to contain mostly-alien-translocation chromosome(TLr.14L·Lr.14S-W).T14 was proved to contain a translocation between Lr.14L and 6BS,with approximatebreakpoint at 6BS2.2 region, FL0.22 in the short arm of chromosome T6BL.6BS-Lr.14L.

用普通小麦-大赖草Lr.14二体异附加系经辐射处理过的花粉给扬麦5号和绵阳11号授粉，M1代植株进行PMC MI染色体配对分析和Giemsa C-分带，选出PMCMI小麦和大赖草染色体发生配对的植株进行自交，M2代经RTC M期染色体C-分带和原位杂交，鉴定出3个小麦-大赖草易位系，其中T12为由Lr.14大部分和一个小麦染色体片段组成的易位染色体(TLr.14L·Lr.14S-W)；T13含由Lr.14染色体绝大部分与小麦染色体的一个小片段组成的易位染色体(TLr.14L·Lr.14S-W)；T14易位系的染色体易位发生在小麦6BS2.2区和大赖草Lr.14L之间，易位断点在T6BL·6BS-Lr.14L易位染色体的FL0.22附近。
