摘要
A mRNA whole-mount in situ hybridization method is reported here for quick, direct analysis of the spatial and temporal mRNA expression patterns in plant young embryos. A cDNA clone THE3 (tobacco heart embryo 3) was isolated by differential screening from tobacco ( Nicotiana tabacum L.) heart embryo cDNA library as compared with the globular embryo cDNA library. The distribution of THE3 mRNA in tobacco heart embryos and globular embryos was investigated by a whole-mount in situ hybridization technique, showing that THE3 is preferentially expressed in heart embryos.
