The growth of transgenic canola (Brassica napus) expressing a gene for the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase was compared to non-transformed canola exposed to flooding and elevated soil Ni concentration, in situ. In addition, the ability of the plant growth-promoting bacterium Pseudomonas putida UW4, which also expresses ACC deaminase, to facilitate the growth of non-tran...

Technology development is seminal to many aspects of basic and applied plant transgenic science. Through the development and commercialization of genetically modified crops, the evolution of plant transgenic technologies is also relevant to society as a whole. In this study, literature statistics were used to uncover trends in the development of these technologies. Publication volume and impact...

Abiotic stress results in massive loss of crop productivity throughout the world. Because of our limited knowledge of the plant defense mechanisms, it is very difficult to exploit the plant genetic resources for manipulation of traits that could benefit multiple stress tolerance in plants. To achieve this, we need a deeper understanding of the plant gene regulatory mechanisms involved in stress...

Soil salinity is a major abiotic stress that decreases plant growth and productivity. Recently, it was reported that plants overexpressing AtNHX1 or SOS1 have significantly increased salt tolerance. To test whether overexpression of multiple genes can improve plant salt tolerance even more, we produced six different transgenic Arabidopsis plants that overexpress AtNHX1, SOS3, AtNHX1+SOS3, SOS1,...

In this study, poplar (Populus alba) cellulase (PaPopCel1) was overexpressed in a tropical Leguminosae tree, sengon (Paraserianthes falcataria), by the Agrobacterium tumefaciens method. PaPopCel1 overexpression increased the length and width of stems with larger leaves, which showed a moderately higher density of green color than leaves of the wild type. The pairs of leaves on the transgenic pl...

Arsenic is a toxic pollutant present in the environment that causes serious health issues. Phytoremediation is one potential solution to mitigate arsenic contamination in either soil or water. Two main forms of arsenic exist in the environment, arsenite, [As(III)], and arsenate, [As(V)]. In plant mechanisms, arsenate reductase reduces arsenate to arsenite with the help of thioredoxins or glutar...

It has been suggested that the rol genes of Agrobacterium rhizogenes could play an essential role in the activation of secondary metabolite production in plant transformed cultures. This study investigated whether the content of anthraquinone phytoalexins was changed in callus cultures of Rubia cordifolia transgenic for the 35S-rolB and 35S-rolC genes in comparison with a non-transformed callus...

abstract the purpose of this research was to transform two economically important cultivars of strawberry with p5cs gene, which encodes δ1-pyrroline-5-carboxylate synthetase (p5cs), the key enzyme in proline biosynthesis. shoots were obtained on ms basal medium supplemented with 2% glucose and 4 mg/l tdz for camarosa and kurdistan cultivars. for genetic transformation, a binary vector pbi121 co...
