An Approach to mRNA Whole-mount in Situ Hybridization for Plant Young Embryos

LI Shi-Tao, Lü Ying-Tang, YANG Hong-Yuan   


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 THE 3 is preferentially expressed in heart embryos.
