Plant development consists of the initial phase of intensive cell division followed by continuous genome endoreduplication, cell growth, and elongation. The maintenance of genome stability under these conditions is the main task performed by DNA repair and genome surveillance mechanisms. Our previous work showed that the rate of homologous recombination(More)
Brassica napus (canola) is the second largest oilseed crop in the world. It is among the first crops to be genetically transformed, and genetically modified cultivars are in commercial production at very significant levels. Despite the early lead with respect to transgenesis, there remain cultivars that are recalcitrant to transformation. To address this,(More)
In the present study, interactions between the duration of treatment with auxin and different cytokinins and their effect on shoot regeneration were evaluated with the aim to establish a rapid and efficient in vitro regeneration method applicable to a variety of Populus species. Three different species, Populus angustifolia, P. balsamifera, and P. deltoids,(More)
The frequency of plant transformation can be improved by addition of various chemical into transformation media. In the past, we showed that exposure of tobacco, wheat and triticale explants to ammonium nitrate, cerium and lantanium chloride and potassium chloride resulted in an increase in the frequency of transformation. Here, we tested whether a(More)

Cell-penetrating peptides (CPPs) are short 8-30 amino-acid oligopeptides that act as effective transducers of macromolecular cargo, particularly nucleic acids. They have been implemented in delivering dsDNA, ssDNA, and dsRNA into animal and plant cells. CPPs and nucleic acids form nano-complexes that are often 100-300 nm in size but still effectively(More)
Microspore cell death and low green plant production efficiency are an integral obstacle in the development of doubled haploid production in wheat. The aim of the current study was to determine the effect of anti-apoptotic recombinant human B-cell lymphoma-2 (Bcl-2△21) and caspase-3-inhibitor (Ac-DEVD-CHO) in microspore cell death in bread wheat cultivars(More)
Microspores are the pre-gametophyte stage of pollen, and have proven to be a successful tissue culture material for the production of doubled haploid plants. Microspore culture has also been used as a platform for the production of transgenic plants. The use of cell-penetrating peptides (CPPs) as transfection agents in microspores has been previously(More)
The present study demonstrates Agrobacterium tumefaciens-mediated stable genetic transformation of two species of poplar - Populus angustifolia and Populus balsamifera. The binary vector pCAMBIA-Npro-long-Luc containing the luciferase reporter gene was used to transform stem internode and axillary bud explants. Putative transformants were regenerated on(More)
