Abiotic stress has been shown to limit the growth, development, and productivity of crops. Here, we characterized the function of a rice bZIP transcription factor OsbZIP16 in drought stress. Expression of OsbZIP16 was dramatically induced under drought conditions. Transient expression and transactivation assays demonstrated that OsbZIP16 was localized in the nucleus and had transactivation acti...

Drought stress is a severe environmental factor that greatly restricts plant distribution and crop production. Recently, we have found that overexpressing AtWRKY57 enhanced drought tolerance in Arabidopsis thaliana. In this study, we further reported that the Arabidopsis WRKY57 transcription factor was able to confer drought tolerance to transgenic rice (Oryza sativa) plants. The enhanced droug...

Gressel et al. (2014; in this issue of New Phytologist, pp. 360–362) disapprove of media coverage of our recent peer-reviewed paper (Wang et al., 2014; this issue ofNewPhytologist, pp. 679–683), and they question whether the paper can be seen as ‘deserving publication’. In this study, our main hypothesis was that overproduction of a key metabolic enzyme (EPSPS) may have the unanticipated effect...

To investigate the role of Ser162 in phosphorylation-dependent regulation of maize sucrose-phosphate synthase (SPS) activities in rice, transgenic rice plants expressing wild-type or mutagenized maize SPS were produced. Our results indicate that Ser162 was responsible for overproduction-induced inactivation of SPS protein and for light/ dark modulation of this protein in vivo.

We have generated transgenic rice plants expressing the Datura stramonium adc gene and investigated their response to drought stress. We monitored the steady-state mRNA levels of genes involved in polyamine biosynthesis (Datura adc, rice adc, and rice samdc) and polyamine levels. Wild-type plants responded to the onset of drought stress by increasing endogenous putrescine levels, but this was i...

Citespace and other visualization software were used to analyze the knowledge graph of relevant pieces literature on GM research in past decade, sort out number trend, core authors, institutions, journals published, keyword co-occurrence gm decade. The analysis shows that interest TRANSGENIC has changed recent ten years. United States, China, countries is similar contribution sun, moon, stars, ...

Rice tungro bacilliform virus (RTBV) replicates only in phloem cells in infected rice plants and its promoter drives strong phloem-specific reporter gene expression in transgenic rice plants. We isolated a cDNA encoding a basic leucine zipper (bZIP) protein, RF2a, which binds to the Box II cis element that is important for expression from the promoter. RF2a, which stimulates Box II-dependent tr...

This study used a static, partial budgeting approach to estimate the potential net benefits of the adoption of herbicide-tolerant transgenic rice in California. Scenarios were developed based on average cost figures across the state using actual pesticide use data and assuming a rice-only rotation, as well as a three-year field study of efficacy of herbicide regimes in the presence of herbicide...

The transgenic tobacco plants have been generated that express the E. coli beta-glucuronidase (GUS) gene under control of the promoter from the rice proliferating cell nuclear antigen (PCNA, DNA polymerase auxiliary protein) gene. GUS expression detected in situ by staining with the chromogenic substrate, 5-bromo-4-chloro-3-indolyl-beta-D-glucuronide (X-Gluc), was restricted to meristems in the...

We examined the function of the rice (Oryza sativa L.) antiporter-regulating protein OsARP by overexpressing it in tobacco (Nicotiana tabacum L.). In public databases, this protein was annotated as a putative Os02g0465900 protein of rice. The OsARP gene was introduced into tobacco under the control of the cauliflower mosaic virus 35S promoter. The transformants were selected for their ability t...
