Main conclusionWe have characterized four novel constitutive promotersARP1, H3F3, HSPandH2BF3that are active in all tissues/stages of transgenic plants and stable over two homozygous generations. Gene promoters that are active and stable over several generations in transgenic plants are valuable tools for plant research and biotechnology. In this study, we characterized four putative...
To be effective in crop biotechnology applications, gene promoters need to be stably active over sequential generations in a population of single-copy transgenic lines. Most of the stress-inducible promoters characterized in plants thus far have been analyzed at early (T0, T1 or T2) generations and/or by testing only a small number of transgenic lines. In our current study, we report our analysis...
We have previously characterized the constitutively active promoters of the APX, PGD1 and R1G1B genes in rice (Park et al. 2010 in J Exp Bot 61:2459–2467). To have potential crop biotechnology applications, gene promoters must be stably active over many generations. In our current study, we report our further detailed analysis of the APX, PGD1 and R1G1B gene promoters in various organs and tissues...
