negative gravitropism meaning in Chinese

负向重性

The materials in this study were arabidopsis thaliana . ( wt ) and its mutants including ethylene over producer mutant ( eto1 - 1 ) , ethylene insensitive root mutant ( eir1 - 1 ) and ethylene insensitive mutant ( etr1 - 3 ) . from the phenotypes of 12 - d - old seedlings of arabidopsis wt and mutants , the root gravitropism was obviously enhanced in etol - 1 , but diminished in eir1 - 1 and etr1 - 3 , compared with wt . the shoot negative gravitropism was also diminished in etiolated seedlings of etr1 - 3
以拟南芥的eth过量产生型突变体( etol - 1 ) ，根对eth不敏感型突变体( eirl - 1 ，地上部对eth响应) ， eth不敏感型突变体( etrl - 3 ，地上部和根均对eth不敏感)及其野生型( wt ， columbia生态型)为实验材料，利用根的向重力性反应为模式，分析了其中eth对auxin效应的调控及其原因。
