Species in the genus Thinopyrum are important wild relatives for wheat improvement. They possess many desirable traits such as drought, cold and salt tolerance, long spikes and more florets, high protein concentration. It has also been found that some species are the source of resistance genes for rust and powdery mildew, and especially, the source of resistance to wheat streak mosaic virus and barley yellow dwarf virus .

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。

A significant difference was observed in the distribution of incorporated amounts comared between pistils and stamens.

With a view to knowing more about how NaHSO〓 increased Pn in higher plants, we studied the effects of NaHSO〓 on the cyclic electron flow around PSI in wheat (Jing 411) and rice (Shan-you 63). It was observed that the transient increase in chlorophyll fluorescence after the termination of actinic light was increased and the half-time of re-reduction of P700〓 was shortened in both rice and wheat leaves, indicating that cyclic electron flow around PSI was accelerated by NaHSO〓 treatment.

为探究NaHSO〓促进高等植物光合作用的机理，我们研究了NaHSO〓对小麦（京411）和水稻（汕优63）围绕PSI的循环电子传递影响，实验发现低浓度NaHSO〓可促进小麦和水稻叶片的叶绿素荧光在作用光关闭后的短时上升以及缩短叶片在远红光后P700〓再还原的半时间，表明NaHSO〓可以促进小麦和水稻的围绕PSI的循环电子传递。

Here are the results: there are no clear difference in the length and width of leaf epidermis stomatal apparatus, stoma density and vascular bundle area in 1st internode below the ear between cold and warm type wheat. The vascular bundle area in 2nd internode below the ear of cold type wheat is obvious smaller than warm type wheat's. There are clear difference in the vascular bundle number in unit transverse area of 1st internode and 2nd internode below the ear and the rate of the total area of vascular bundle and the transverse area of wheat stem between cold and warm type wheat.
