查询词典 introns

The OsCMO contains 10 exons and 9 introns and encodes a protein with 410 amino acids,which shows 62﹪, 51﹪, 51﹪, 51﹪ and 50﹪ identities in amino acids to CMOs from Arabidopsis thaliana,Atriplex hortensis, Amaranthus tricolor, Suaeda liaotungensis and Beta vulgaris respectively. Semi-quantitative RT-PCR assay revealed OsCMO was significantly up-regulated in the rice seedlings under salt, cold and drought stresses. It suggests that OsCMO might play an important role in rice responses to abiotic stresses.

Sequencing analysis revealed 3 exons and 2 introns in SKC1 gene, and four amino acids difference between NSKC1 from Nona and KSKC1 from Koshihikari.

序列分析显示SKC1基因由3个外显子和2个内含子构成，Nona和越光的SKC1有4个氨基酸的差异。

Segments of Adh gene in azuki bean (variety KS 5), covering an interval between partial intron 3 and intron 9, were amplified and sequenced with two pairs of primers. The result has proven the viability of using conserved sequences in a completely sequenced gene of one species to clone same gene in another species. In the comparison between Adh genes of azuki bean and pea, high sequence similarity (about 80%) in exon and long length difference (up to 116 bp) in intron were found. Besides, the edge regions of Adh introns with GT/AG counterparts and more conserved sequences than central regions was observed in both species.

利用两组引子对完成红豆(高雄5号)Adh基因之部分解序，其范围包括部分intron 3至intron 9之间的区域，也印证利用基因之已知保守序列可选殖另一物种之相同基因，红豆与豌豆之Adh基因序列比对结果显示两者之exon均较intron有较高之GC百分比(分别为41.0 ~ 48.7%及23.3 ~ 35.2%)，且两者在exon区域之DNA序列相似程度约80 %，而在intron区域中则有明显的序列差异存在(长度差异最高可达116 bp)，但是intron外侧序列均具有GT/AG组成且相对较中央序列具有保守性。

The result of sequence analysis indicated that the length of cDNA and DNA fragments of Lectin gene and the length of cDNA and DNA fragments of Pectate Lyase gene were 508 bp,575 bp,1,316 bp and 1,858 bp respectively.The DNA fragment of Lectin gene had a intron,whose length was 67 bp .The DNA fragment of Pectate Lyase gene had 3 introns,whose lengths were 90 bp,83 bp,and 370 bp respectively. All these four introns sequences followed the rule of GT-AG.

通过序列分析得知，香蕉凝集素基因cDNA片段长508 bp；香蕉凝集素基因DNA片段长575bp，有一个长为67bp的内含子；香蕉果胶裂解酶基因cDNA片段长1，316bp；香蕉果胶裂解酶基因DNA片段长1，858bp，有三个内含子区，分别长90 bp，83 bp和370bp；在总共的四个内含子序列中，分别都符合GT-AG规则。

Point mutation and additional sequence insertion in introns might have given rise to new isoforms.

对比usf1和usf2的各个选择性剪接变体发现，二者的剪接模式都很保守，而新的变体是由点突变或内含子中额外序列的插入造成的。
