| 1 | CIMMYT小麦puroindoline基因型的进一步鉴定与分析显示文摘目的籽粒硬度是小麦市场分级和定价的重要依据,影响磨粉和食品加工品质。CIMMYT是我国最重要小麦引种地之一,研究其硬度基因型对我国小麦引种具有重要的应用价值。方法以CIMMYT常用的236份小麦亲本和高代品系为材料,采用改进的颗粒指数法、特异引物的PCR扩增和改进的SDS-PAGE凝胶电泳对其SKCS硬度及其puroindoine基因型进行鉴定和分析。结果202份硬质麦中,165份为PINA蛋白缺失类型;37份为Pinb-D1b类型,其中19份为非CIMMYT材料,18份亲本中均含有非CIMMYT材料。在34份软质麦中,有野生型、Pina-D1a/Pinb-D1i、Pina-D1c/Pinb-D1h、Pina-D1j/Pinb-D1i和Pina-D1a/Pinb-D1j共5种基因型。两种硬质类型中,Pina-D1b类型胚乳硬质程度明显高于(PSI硬度显著低于)Pinb-D1b类型;4种软质类型中,Pina-D1c/Pinb-D1h和Pina-D1a/Pinb-D1i类型胚乳硬质程度显著高于(PSI硬度显著低于)Pina-D1j/Pinb-D1i和Pina-D1a/Pinb-D1a类型。通过分析各类型的puroindoline基因序列发现,Pinb-D1h和Pinb-D1i编码同一种氨基酸,突变后仍表现为软质是因为第28位精氨酸变成色氨酸,其余软质变异类型色氨酸丰富区附近均未发生变化,这可能是导致其胚乳质地仍未变硬的主要原因。结论在先前研究基础上,本试验对CIMMYT小麦基因型作了进一步分析,发现系谱中没有外源材料的所有CIMMYT硬质麦均为Pina-D1b类型。从山羊草引进的软质突变类型之间存在一定硬度差异。 | 陈锋 夏先春 Manila William Morten Lillemo Richard Trethowan Roberto J Peňa 何中虎 | 2006 | 中国农业科学2006，39，8： | 6 |
| 2 | Relationship between Carbon Isotope Discrimination and Grain Yield in Spring Wheat Cultivated under Different Water Regimes显示文摘在 C 植物,碳同位素辨别() 为谷物产量作为一个间接选择标准被建议了。报导关联在之间和不管多么的谷物产量,根据分析机关或织物高度不同,采样的舞台,和环境和水政体。在处于西北墨西哥的干燥条件在二个连续季节期间在春小麦执行的第一个实验( Ciudad Obregon , Sonora ),不同水处理被使用,相应于对世界范围的春小麦可得到的主要的水政体,并且在不同机关和谷物产量的价值之间的关系被检验。在终端下面(开花期以后) 水应力,谷物产量断然与被联系在在成熟的谷物并且在在开花期的叶,证实以前在地中海环境下面获得的结果。在下面(开花期前) 早,水应力和剩余潮湿强调,在谷物和收益之间的协会更弱并且高度取决于在播种在土壤存储的水的数量。没有关联被发现在之间,谷物在最佳的灌溉下面让步。在之间的关系和谷物产量也在 Ningxia 区域(北中国) 在 20 面包小麦栽培变种在二个连续季节期间被学习,由冬季干旱(开花期前水压力) 描绘了。小麦在另外一个在二个地点(Guyuan 和 Pengyang ) 并且在灌溉条件下面在雨美联储条件下面被种二(银川和 Huinong ) 。在 Huinong,庄稼也被暴露腌应力。高度重要的积极协会越过环境在叶和谷物和谷物收益之间被发现。在生长周期,在土壤的盐的存在,和在开花期前的灌溉的出现期间的降雨的在之间的关系和水的数量在播种在土壤存储了的在高度取决于的环境以内的产量,数量和分发。这二个实验证实了价值作为一种间接选择,为在开花期以后的水下面的产量和一个 phenotyping 工具的标准强调(包括的有限灌溉) 。 | Xing Xu Hanming Yuan Shuhua Li Richard Trethowan Philippe Monneveux | 2007 | Journal of Integrative Plant Biology2007，49，10： | 3 |
