Reporter gene activity under the regulation of the oil palm metallothionein-like gene, MT3-A promoter was assessed in prokaryotes. Vector constructs containing MT3-A promoter with (W1MT3-A) and without (W2MT3-A) five prime untranslated region (5'-UTR) fused to ß-glucuronidase (GUS) gene in pCAMBIA 1304 vector were produced. 5'-rapid amplification of cDNA ends (RACE) using mRNA isolated from Esc...
The tomato (Lycopersicon esculentum cv Ailsa Craig) polygalacturonase genes TAPG1 (LYCes;Pga1;2) and TAPG4 (LYCes;Pga1;5) are abundantly expressed in both abscission zones and the pistils of mature flowers. To further investigate the spatial and temporal expression patterns for these genes, the TAPG gene promoters were ligated to beta-glucuronidase (GUS) reporter genes and transformed into toma...
Commercial cultivation of the mushroom fungus, Agaricus bisporus, utilizes a substrate consisting of a lower layer of compost and upper layer of peat. Typically, the two layers are seeded with individual mycelial inoculants representing a single genotype of A. bisporus. Studies aimed at examining the potential of this fungal species as a heterologous protein expression system have revealed unex...
Transgenic Phytophthora palmivora strains that produce green fluorescent protein (GFP) or beta-glucuronidase (GUS) constitutively were obtained after stable DNA integration using a polyethylene-glycol and CaCl2-based transformation protocol. GFP and GUS production were monitored during several stages of the life cycle of P. palmivora to evaluate their use in molecular and physiological studies....
A novel sequence that functions as a promoter element for moderate constitutive expression of transgenes, designated as the PtMCP promoter, was isolated from the woody perennial Populus tomentosa. The PtMCP promoter was fused to the GUS reporter gene to characterize its expression pattern in different species. In stable Arabidopsis transformants, transcripts of the GUS reporter gene could be de...
The gene expression of two Al-induced Arabidopsis glutathione S-transferase genes, AtGST1 and AtGST11, was analyzed to investigate the mechanism underlying the response to Al stress. An approximately 1-kb DNA fragment of the 5'-upstream region of each gene was fused to a beta-glucuronidase (GUS) reporter gene (pAtGST1::GUS and pAtGST11::GUS) and introduced into Arabidopsis ecotype Landsberg ere...
beta-glucuronidase (GUS) is a reporter protein commonly expressed in transgenic plants allowing the visualization of the transformed individuals. In our recent work, we showed that consumption of transformed potato plants expressing this GUS enzyme improves performance of the phloem feeding aphid Myzus persicae. Those results led us to the conclusion that the expression of GUS in potato plants ...
Stably transformed Arabidopsis lines in which GUS marked cell clones are readily produced in response to heat-shock have been established and characterized. Control of GUS activation is achieved by heat-shock-induced FLP recombinase activity which "switches on" expression of a GUS marker gene previously held transcriptionally silent. To obtain efficient GUS sectoring, single insert Arabidopsis ...
We isolated the 5’ upstream promoter regions of the fruit-type sucrose synthase (SS) gene from tomato and Japanese pear by inverse PCR. The 5’ region of the tomato SS gene (TOMSSF) contained an intron approximately 1.6 kbp long in the 5’untranslated region, whereas the equivalent 5’ region in the Japanese pear SS gene (PypSUS1) had no intron. Each region was fused to the β-glucuronidase (GUS) g...
