| 摘要 | 应用二维电泳技术 ,分析了经水分胁迫 ( PEG)、盐分胁迫 ( NaCl)和热激 ( 40℃ )处理后林生山黧豆 (Lathyrus sylvestris L. )体内蛋白质多肽及其含量的变化。有些蛋白质经 PEG、 NaCl和热激处理后可以产生相同的变化。 两种不同的胁迫因子对某些蛋白质的影响有一定的共同性。 特定的胁迫条件可以造成特定的影响。 不同胁迫因子对同一蛋白质多肽可以造成不同的影响。 胁迫下蛋 |
| Abstract | Protein polypeptide contents in Lathyrus sylvestris L. treated with water stress ( PEG) , salt stress ( NaCl) and high temperature ( 40℃ ) were analyzed with twodimensional electrophoresis. The results show ed that: 1) identical changes in some protein polypeptide contents were detected when plants were treated with PEG,NaCl and high temperature; 2) similar effects on some roteins by two different factors were found; 3) specific change was related to specific stress factor; 4)different stress factors could cause different responses by same protein polypeptide.The changes in protein polypeptide contents are probably related to the stress tolerance or resistance and the metabolism of non-protein amino acid in Lathyrus sylvestris L. |
