Phosphomannose isomerase, pmi, as a selectable marker gene for durum wheat transformation
Transgene technology provides a powerful tool for developing traits that are otherwise difficult to achieve through conventional methods. The development of transgenic plants requires the use of selectable marker genes, as the efficiency of plant transformation is less than optimal for many important species, especially for monocots such as durum wheat (Triticum turgidum var. durum). Many conce...
متن کاملMannose-Based Selection with Phosphomannose- Isomerase (PMI) Gene as a Positive Selectable Marker for Rice Genetic Transformation
A positive selectable marker system was adapted for transformation of mature embryo-derived calli of Indica rice (Oryza sativa L.) utilizing the PMI gene encoding for phosphomannose-isomerase that converts mannose-6-phosphate to fructose-6-phosphate. The transformed cells grew on medium supplemented with 3% mannose as carbon source and calli were selected on media containing various concentrati...
متن کاملPhosphomannose Isomerase, A Novel Selectable Plant Selection System: Mode of Action and Safety Assessment
Phosphomannose isomerase (PMI), an enzyme not present in many plants, catalyzes the reversible interconversion of mannose 6-phosphate and fructose 6-phosphate. Plant cells lacking this enzyme are incapable of surviving on synthetic medium containing mannose. Plants derived from sugar beet and corn cells that had been genetically modified to express the E. coli manA gene encoding PMI were evalua...
متن کاملArabidopsis phosphomannose isomerase 1, but not phosphomannose isomerase 2, is essential for ascorbic acid biosynthesis.
We studied molecular and functional properties of Arabidopsis phosphomannose isomerase isoenzymes (PMI1 and PMI2) that catalyze reversible isomerization between D-fructose 6-phosphate and D-mannose 6-phosphate (Man-6P). The apparent K(m) and V(max) values for Man-6P of purified recombinant PMI1 were 41.3+/-4.2 microm and 1.89 micromol/min/mg protein, respectively, whereas those of purified reco...
متن کاملChlorimuronethyl Resistance Selectable Marker Unsuited for the Transformation of Rice Blast Fungus (Magnaporthe Grisea)
Chlorimuronethyl resistance gene is increasingly used as a selectable marker for transformation, especially fungal transformation. Magnaporthe grisea is an important model organism for investigating fungal pathogenicity, and Agrobacterium tumefaciens-mediated transformation (ATMT) is used for functional mutagenesis of the fungus. However, our results showed that rice blast strains collected fro...
