查询词典 yellow blight

Oligosaccharides could induce obvious resistance to powdery mildew, head blight and stripe rust of wheat. However, the effects on different diseases are quite different due to Oligosaccharides derivation, time for enzyme extraction and the concentration used.

The results showed that one protein peak (designated P0) was bigger in resistant varieties When the sample were inoculated with spores or H202, but no difference in susceptible varieties, so protein P0 was related to wheat resisting Fusarium head blight.

结果表明，所有抗性品种在用病原物接种或过氧化氢处理后，蛋白质P_0的吸收峰明显增高，而在感性品种中差异不明显，P_0是与小麦抗赤霉病相关的蛋白。

Probably these proteins were related to wheat resisting Fusarium head blight.

研究结果表明，所有品种都含有4个洗脱体积为8ml(P_0)、18.20ml(P_1)、20.20ml(P_2)和20.80ml(P_3)的蛋白吸收峰。

Since 80s,the infected area by head blight of wheat (Fusarium gramin-earum,Schw,) has been developing and the degree of development increasing gradually year after year,because of the change of cuhivating system and the availabe irrigation condition, which formed a farmland- ecologic environmet there was adventageous to outbreack of the disease.

宁夏引黄灌区自80年代中期以来，由于耕作制度的改变，又有灌溉条件，构成了有利于小麦赤霉病发生和流行的农田生态环境，发病面积逐年扩大，发病程度不断加重。

After non-inoculated samples were treated with H2O2, peaks of protein had the trend of left-moving in resistant varieties, but trend of right-moving in susceptible varieties. So, when H2O2 existed, enchancement of POD activity impelled low-weight substance to polymerize high-weight protein in resistant varieties, but no difference in susceptible varieties.Samples from callus of five wheat varieties with varying degrees of resistance against wheat head blight were examined by FPLC.

对照样品在过氧化氢水浴(35℃)处理后，抗性品种的蛋白峰有&左移&现象，P_0峰有所提高，表现与赤霉病菌接种处理一致的趋势，因而，在H_2O_2存在的前提下，抗性品种中POD活力的提高促使小分子量物质聚合成大分子量的蛋白，而在感性品种中没有这些变化的出现。

Three recombinant inbred populations,Ning894037/Alondra,Wangshuibai/Alondra and Sumai3/Alondra, were analyzed for QTLs associated with Fusarium head blight resistance by interval mapping and composite interval mapping in this study. The result showed that the major QTLs were detected on the short arm of chromosome 3B of all three resistant parents using the data of FHB resistance evaluated in greenhouse or field.

采用区间作图和复合区间作图方法对重组自交系群体宁894037/Alondra、望水白/Alondra和苏麦3号/Alondra进行了抗赤霉病QTL分析，结果表明，用在田间和温室的赤霉病抗性鉴定资料，在3个赤霉病抗源宁894037、望水白和苏麦3号的3B染色体短臂上均检测到主效QTL的存在。

Filed experiments of 2001 showed that treatments with fungicide either 2 days before or 2 days post inoculation, tebuconazole reduced the disease index of the spikes by 80.32% and 70.64, as well as increased grain yield by 12.95% and 8.74% in comparison to the untreated control. Application of metconazole led to decreases of the disease index by 80.5% and 68.0% and increases of grain yield by 11.41% and 11.45% compared with the untreated plants. In 2002, with the serious occurrence of the head blight, tebuconazole reduced the disease index of the spikes by 76.47% and 78.67% and metconazole reduced the disease index by 82.06% and 81.89% in comparison to the untreated control.

田间药效测定结果表明：与对照相比，接种前2d喷药与接种后2d喷药，2001年，戊唑醇可使小麦赤霉病病情指数分别减少80.32%和70.64%，产量增加12.95%与8.74%；羟菌唑可使小麦赤霉病病情指数减少80.5%和68.0%，产量增加11.41%和11.45%；2002年，在小麦赤霉病严重发生的情况下，戊唑醇能使小麦赤霉病病情指数减少76.47%和78.67%，羟菌唑能使小麦赤霉病病情指数减少82.06%和81.89%，产量增加极显著。

The sequences were compared with the known sequences in Genbank with BLAST software. P-ACC/M-GGA200 showed 95% homology to a part of AFLP sequence which linked to fusarium head blight resistance gene fragment (AF389881). The P-AGG/M-GGT_(251) has an ORF, and it had homology to a hypothetical protein of Oryza sativa.

根据BLASTn同源性比较，P-ACC/M-GGA_(200)与GenBank中与抗小麦赤霉病连锁的一段AFLP序列(AF389881)同源性达95%；P-AGG/M-GGT_(251)序列中含有一个开放阅读框，根据BLASTp同源性比较，与GenBank中日本栽培稻一未知蛋白(XP 483138)有同源性。

Head blight not only causes the severe grain yield loss, but also causes the harvested grain contaminated with several mycotoxins, such as deoxynivalenol and zearalenone. The consumption of food product made from grains contaminated with these toxins is a potential problem for human and farm animals, which is known to cause carcinogenic, genotoxic acute or chronic diseases or to directly target the kidney, liver or immune system, and has caused great concern of food safety.

赤霉菌引起小麦的穗腐，不仅使小麦籽粒产量降低、品质变劣，而且病麦粒中存留有病菌产生的真菌毒素，如脱氧雪腐镰刀菌烯醇(Deoxynivalenol，DON)和玉米赤霉烯酮(Zearalenone，ZEN)，食用污染毒素的病麦及其制成品后会引起人畜中毒，还有致癌、致畸和诱变的作用。
