Coordinate sequence method is made up of the instruct information of polygon boundary x, y coordinate. It is the easiest polygon vector encoding method. The file structure of this method is easy, but because of the polygon boundary has stored two times, it will produce data redundancy, moreover, short of neighbor threshold information; Tree index encoding method make all the boundary points digitizing, store the coordinate sequence, connect the point index to boundary line, and then connect the line index to other polygons, so as to the tree index structure has came into being. It eliminates neighbor polygons boundary data redundancy problems; Topology structure encoding method is a method which by setting up a complete topology relationship structure, resolve the neighbor threshold and island information process problem. However, it makes arithmetic more complicated and makes database bigger.

坐标序列法是由多边形边界的x，y坐标对集合及说明信息组成，是最简单的一种多边形矢量编码法，文件结构简单，但多边形边界被存储两次产生数据冗余，而且缺少邻域信息；树状索引编码法是将所有边界点进行数字化，顺序存储坐标对，由点索引与边界线号相联系，以线索引与各多边形相联系，形成树状索引结构，消除了相邻多边形边界数据冗余问题；拓扑结构编码法是通过建立一个完整的拓扑关系结构，彻底解决邻域和岛状信息处理问题的方法，但增加了算法的复杂性和数据库的大小。

Gene sequence was highly homologic with a gene encoding aβ- subunit of ATP synthetase and an EST originating from a cDNA in relation to water deficit stress, which both were closely associated with the protein functioning in stress resistance and ion transportation. The results suggested that No. 1 gene sequence was involved in stress resistance of apple rootstock. No. 2 gene sequence had high homology with a gene encoding a serine/ threonine kinase protein, indicating perhaps it was a new gene encoding the serine/ threonine kinase protein in apple rootstock. The gene sequences of A1 and A2 were highly homologic with a gene encoding aβsubunit of ATP synthetase.

对得到的差异片断进行回收、测序，通过BLAST和其它植物比对，发现Ⅰ号序列与一条编码ATP合酶β亚基基因和一条水分亏缺胁迫cDNA克隆基因EST的同源性非常高，该序列编码涉及到了抗性表达、离子转运基因，可能参与了植物抗性表达，说明获得的基因序列应是与苹果砧木抗性相关的基因；Ⅱ序列与一条serine/threonine kinase蛋白激酶的蛋白序列同源性比较高，核酸比对较低，可能是具有丝氨酸/苏氨酸蛋白激酶功能的新基因。A1、A2序列与一条编码ATP合酶β亚基基因的同源性较高。
