| 摘要: |
| 应用凝胶电泳技术研究了普通小麦生育早期过氧化物酶同工酶(IPO)的表达特性与遗传规律。结果表明:IPO分子有稳定表达型与可变表达型之分,前者无时空特异性,后者有时空特异性;在个体生长发育过程中,不同的IPO分子具有不同的表达频率;稳定表达型IPO的表达均呈共显性遗传;而各可变表达型IPO的表达,则在一定的遗传背景和一定的时空位点上均呈不同遗传模式的转换。 |

| Abstract: |
| The expression property and genetic patterns of peroxidase isozymes (IPO) in the early growth and development stage of common wheat (Triticum aestivum L.) were studied by using PAGE-technique. The results showed that there were two types of IPO moleculars in the variable and stable expression types; the former was not of specificity in space and time* but the later wasi and there were also different expression frequencies for different IPO moleculars in the growth and development process of the individual' and the expression of the stable expression type of IPO molecular behaved genetically as a codomonance?but the expressions of the variable expression type of IPO molecular behaved genetically as the definite conversions of different genetic patterns on the definite genetic background and the definite locus in space and time. |
