    Systemic induction of proteinase-inhibitor-II gene expression in potato plants by wounding (1988)
    Springer
    Planta 174 (1988), S. 84-89

    ISSN: 1432-2048
    Keywords: Gene expression (systemic induction) ; Proteinase inhibitor II ; RNA (proteinase inhibitor II) ; Solanum (gene expression) ; Wounding (gene expression)

    Notes: Abstract The systemic induction of expression of the gene for proteinase inhibitor II after wounding different parts of potato (Solanum tuberosum L.) plants was analysed at the RNA level. Wounding of either leaves or tubers led to an induction of expression of this gene in non-wounded upper and lower leaves as well as in the upper stem segment, whereas no expression was observed in nonwounded roots or in the lower stem segment. The signal mediating the systemic induction in nonwounded tissue must therefore be able to move both acropetally and basipetally. The systemic wound response is specific for the expression of the proteinase-inhibitor-II gene as no influence was observed for the expression of genes encoding the small subunit of ribulose-1,5-bisphosphate carboxylase and the tuber storage protein patatin which were examined in parallel with the proteinase-inhibitor-II gene.

    The expression of a chimeric Phaseolus vulgaris nodulin 30-GUS gene is restricted to the rhizobially infected cells in transgenic Lotus corniculatus nodules (1994)
    Springer
    Plant molecular biology 26 (1994), S. 1995-2001 
    Details
    ISSN: 1573-5028
    Keywords: gene regulation ; nodule ; nodulin ; Phaseolus vulgaris ; transgenic plants

    Topics: Biology
    Notes: Abstract In Phaseolus vulgaris there is a nodulin family, Npv30, of ca. 30 kDa, as detected in an in vitro translation assay [2]. We isolated a gene (npv30-1) for one of the members of this family. The nucleotide sequence of the promoter of npv30-1 contains nodule-specific motifs common to other late nodulin genes. The promoter was fused to the GUS reporter gene; this chimeric fusion was introduced into Lotus corniculatus via Agrobacterium rhizogenes transformation. GUS activity was only detected in the infected cells of the nodules of transgenic plants. By contrast, the expression of a 35S-GUS construct was restricted to the uninfected cells and the vascular tissue.
