Undesired Small RNAs Originate from an Artificial microRNA Precursor in Transgenic Petunia (Petunia hybrida)
Although artificial microRNA (amiRNA) technology has been used frequently in gene silencing in plants, little research has been devoted to investigating the accuracy of amiRNA precursor processing. In this work, amiRNAchs1 (amiRchs1), based on the Arabidopsis miR319a precursor, was expressed in order to suppress the expression of CHS genes in petunia. The transgenic plants showed the CHS gene-s...
متن کاملEffects of sulfur nutrition on expression of the soybean seed storage protein genes in transgenic petunia.
The 7S seed storage protein (beta-conglycinin) of soybean (Glycine max [L]. Merr.) has three major subunits; alpha, alpha', and beta. Accumulation of the beta-subunit, but not the alpha- and alpha'-subunits, has been shown to be repressed by exogenously applied methionine to the immature cotyledon culture system (LP Holowach, JF Thompson, JT Madison [1984] Plant Physiol 74: 576-583) and to be e...
متن کاملTranscriptome Changes Associated with Delayed Flower Senescence on Transgenic Petunia by Inducing Expression of etr1-1, a Mutant Ethylene Receptor
Flowers of ethylene-sensitive ornamental plants transformed with ethylene-insensitive 1-1(etr1-1), a mutant ethylene receptor first isolated from Arabidopsis, are known to have longer shelf lives. We have generated petunia plants in which the etr1-1 gene was over-expressed under the control of a chemically-inducible promoter, which would allow expression of etr1-1 to be initiated at the desired...
متن کاملIsolation barriers between petunia axillaris and Petunia integrifolia (Solanaceae).
The isolation barriers restricting gene flow between populations or species are of crucial interest for understanding how biological species arise and how they are maintained. Few studies have examined the entire range of possible isolation barriers from geographic isolation to next generation hybrid viability. Here, we present a detailed analysis of isolation barriers between two flowering pla...
متن کاملDifferential expression of two MADS box genes in wild-type and mutant petunia flowers.
We isolated and characterized two flower-specific genes from petunia. The protein products of these genes, designated floral binding protein 1 (FBP1) and 2 (FBP2), are putative transcription factors with the MADS box DNA binding domain. RNA gel blot analysis showed that the fbp1 gene is exclusively expressed in petals and stamen of petunia flowers. In contrast, the FBP1 protein was only detecta...
