To provide effective and specific native promoters for canola (Brassica napus L.) genetic modification, three promoters were isolated by genome walking from this species. These three promoters were fused to the uidA reporter gene (GUS) and were independently used to generate populations of transgenic canola plants. Plants transformed with BnPGPro-GUS (B. napus putative germin promoter) exhibited GUS activity in all the tissues tested at a level comparable to those transformed with CaMV35 S promoter. This indicates that BnPGPro may serve as a native constitutive promoter for canola. The other two promoters, BnPro3-GUS and BnPro5-GUS (B. napus, promoter 3 and 5), exhibited GUS activity in various tissues. None of these two promoters expressed in embryo, however. These novel Brassica native promoters can be used to modify canola genes for various purposes.

<p>Reporter gene assays are commonly used to study the expression pattern of a gene and the promoter activity. The purpose of this study was to assemble the chimeric gene constructs consisting of CaMV 35S promoter orOsAER1 gene promoter connected to the β-glucuronidase (GUS) reporter gene encoding the β-glucuronidase enzyme and to obtain an efficient method for Agrobacterium tumefaciens-mediated transient transformation of tobacco sprouts. The CaMV 35S promoter fragment reamplified from pCAMBIA1301 binary vector and the OsAER1 gene promoter fragment amplified from rice cv. Awan Kuning were ligated into pCAMBIA1300int::gus::tNOS to produce binary vectors pCAMBIA1300int::p35S::gus::tNOS and pCAMBIA1300int::prOsAER1::gus::tNOS. The vectors were used for transient transformation of 5–day old tobacco seedlings. The transformation was carried out using two bacterial cultures with densities of OD600 = 0.5 or OD600 = 1.0 combined with a vacuum for 15 or 30 minutes. Tobacco seedlings transformed with pCAMBIA1300int::p35S::gus::tNOS showed higher transformation efficiency as compared tothe ones transformed with pCAMBIA1300int::prOsAER1::gus::tNOS. A higher efficiency was obtained from transformation using bacterial culture with density of OD600 = 0.5 in combination with a vacuum for 30 minutes. Expression of GUS gene in the tobacco sprouts transformed with CaMV 35S promoter construct was observed through out the sprouts area (root, hypocotyl, cotyledon, and leaf), where as expression of GUS gene was observed in root, hypocotyl, and cotyledon, but not in leaf on tobacco sprouts transformed with OsAER1 promoter construct. These results indicate that the transient transformation is a quick and simple method for testing a chimeric gene construct.</p>

Abstract Background Fresh water bodies represent less than 1% of overall amount of water on earth and ensuring their quality and sustainability is pivotal. Although several campaigns have been performed to monitor the occurrence of micropollutants by means of chemical analysis, this might not cover the whole set of chemicals present in the sample nor the potential toxic effects of mixtures of natural and anthropogenic chemicals. In this sense, by selecting relevant toxicity endpoints when performing in vitro bioanalysis, effect-based methodologies can be of help to perform a comprehensive assessment of water quality and reveal biological activities relevant to adverse health effects. However, no prior bioanalytical study was performed in wetland water samples from the Spanish Mediterranean coastline. Methods Eleven samples from relevant water bodies from the Spanish Mediterranean coastline were collected to monitor water quality on 8 toxicity endpoints. Aryl hydrocarbon receptor (AhR), androgenicity (AR+ and AR−), estrogenicity (ER+ and ER−), oxidative stress response (Nrf2) and vitamin D receptor (VDR+ and VDR−) reporter gene assays were evaluated. Results AhR was the reporter gene assay showing a more frequent response over the set of samples (activated by 9 out of 11 samples), with TCDD-eq in the range 7.7–22.2 pM. For AR, ER and VDR assays sporadic activations were observed. Moreover, no activity was observed on the Nrf2 reporter gene assay. Wastewater and street runaway streams from Valencia could be responsible for enhanced activities in one of the water inputs in the Natural Park ‘L’Albufera’. Conclusions Water quality of relevant wetlands from the Spanish Mediterranean coastline has been evaluated. The utilization of a panel of 5 different bioassays to cover for different toxicity endpoints has demonstrated to be a good tool to assess water quality.
