It is well known that Huang-huai-hai Plain flourished around Han and Tang dynasties, not only boasted of the highly developed agricultural economy, handicraft industry and cultural education, but also of the population quality and proportion. while the physiognomy of the Plain has changed greatly since Song and Yuan dynasties due to the frequent deluge and the river course change of Yellow River, which caused the changes of the trace elements amount in the plain\'s soil, especially the decrease of virtual zinc which caused the cultural developing process to stagnate gradually after Song and Yuan dynasties. Trace elements like a invisible hand worked uniquely on cultural developing process.3The geographical environment and the morbid population of Lin Xiang Kingdom in Sun-Wu Kingdom Period.

二地理环境下的土壤微量元素的变化状况与历史时期黄淮海平原文明进程的关系：众所周知，汉唐时期是黄淮海平原地区文明程度最高的时期，不仅农业经济、手工业经济和文化教育高度发展，而且人口素质和人口比重也是占据极为重要地位；但是，由于黄河的频繁泛滥和改道，不仅造成了黄淮海平原地貌的巨大变化，而且也引发了黄淮海平原土壤微量元素的变化，以致有效锌严重缺乏，从而使得宋元以后的黄淮海平原的文明进程逐渐停滞下来；而在此过程中，土壤微量元素锌像一支看不见的手在起着独特的作用。

Nested PCR analysis and southern hybridization analysis showed that no polymorphism between H.villosa, Pm97034 and susceptible parent Wan7 107 was detected with the clones from 6VS arm, whereas three clones from H.villosa genome DNA: RH42, RH55, and RH66 showed polymorphism. RGA6 cloned from H.villosa genome DNA was characterized identity to NBS, and show high homology to resistance genes as RPM1 and RPP13 in Arabiadopsis, LRR19 in wheat, and I2C-1 in tomato.cDNA library constructed from T.aestivum-H.villosa translocation line Pm97034 was screened by hybridization with RGA6. Four positive cDNA clones were obtained. R3-2-2 showing 60-90% identity with eukaryotic sulfite oxidases contained an open reading frame of 647bp encoding 140 amino acid, and contained a conserved Moco-dimer domain in the ORF. R6-2-2 showed an ORF containing an Euk-porin domain of 279aa with 20-40% identity to the eukaryotic voltage-dependent anion channel proteins. R8-1-1 showed a complete ORF of 1810bp encoding 493aa with 80-90% identity to plant catalases. R9-1-1 showed an ORF containing a BTB/POZ conserved domain of 204aa with 30-70% identity to pox virus and zinc finger proteins. R3-2-2 and R9-1-1 were the first cDNA clones containingconserved domain of SO and POZ respectively isolated from wheat. R8-1-1 contained a complete ORF with 81% identity to Cat-3. Aspects of the role of R8-1-1 may be same with Cat-3, and it would offer the opportunity for improvement of stress tolerance of wheat.

以RGA6为探针，筛选用抗白粉病小麦—簇毛麦易位系Pm97034构建的cDNA文库，得到了4个阳性克隆。R3-2-2与动植物的亚硫酸氧化酶(sulfite oxidase，SO)有60～90％的同源性，长度为647bp，编码140个氨基酸，具有开放阅读框并含有保守域Moco-dimer.R6-2-2与真核生物的VDAC(voltage-dependent anion chennel)蛋白有20～40％的同源性，长度为1047bp，编码279aa，是一个不完整的开放阅读框，预测结构具有Euk-porin结构域。R8-1-1与植物中已经克隆的过氧化氢酶有80～90％的同源性，长度为1810bp，编码493aa，具有完整的开放阅读框和过氧化氢氧化酶保守域。R9-1-1与动植物的POZ(pox virus and zinc finger protein)蛋白有30～70％的同源性，长度为1446bp，具有开放阅读框和BTB／POZ保守域。R3-2-2与R9-1-1是首次从小麦中克隆到的具有SO和POZ保守域的cDNA序列。R8-1-1具有完整的开放阅读框，与玉米Cat-3基因具有81％同源性，预测R8-1-1可能具有与Cat-3类似的功能，可为转基因小麦抗逆育种提供新的基因。
