All 21 exons with flanking intronic sequences, as well as a 263 bp fragment of the 5" flanking region, of GARS-AIRS-GART gene, were screened in the same five populations, by the method of PCR-SSCP analysis, combined with sequencing reactions. We detected 10 SNPs, C-179T from 5" flanking region, A5669G form exon 3, C6545Afrom exon 4, A7777G from intron 4, G10854T, C10867T, G10898T from intron 6, A16197G from intron 11, C21228T from intron 14, and C29686T from exon 21. These ten polymorphic sites were nominated as GARS1, GARS2, GARS3, GARS4, GARS5, GARS6, GARS7, GARS8, GARS9, and GARS 10, respectively. The mutation of C D A at GARS3 was a non-synonymous mutation, wh

其中外显子4中的6545处的c~A突变导致对应的氨基酸序列中的第173位氨基酸发生变异：天冬氨酸一谷氨酸；10个SNP位点依次命名为：GARSI、GARSZ、GARS3、GARS4、GARSS、GARS6、GARS7、GARSS、GARSg、GARS 10；(2)10个SN'P位点在不同的鸡种中的基因型分布差异显著(P.05)，进一步的方差分析显示，GASRI位点以及GARS3位点与肌肉肌昔酸含量之间存在着显著的关联；(3)在所检测的5个群体中GARsl位

Polymorphism of Rb (intron 17) is relatively stable and rarely mutates, but poly morphism of Rb gene (intron 20) locus is characteristic in the old people. The r elation between Rb gene (intron 20) and ageing needs further study.

老年组Rb基因20内含子的位点多态性与青年组比较差异有显著性意义，是否该位点遗传标记与细胞的衰老有一定的相关性，值得进一步研究。

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。
