Electroporation-mediated gene transfer into intact plant tissues was demonstrated in pea, cowpea, lentil, and soybean plants.
Transient expression of a chimericgus reporter gene was used to monitor the uptake and expression of the introduced DNA in electroporated nodal axillary buds in
vivo. The branches that grew out of the nodal meristems were chimeric and expressed the introduced gene up to 20 d after electroporation.
Transgenic R1 pea, lentil, and cowpea plants were recovered from seeds originating on these chimeric branches as shown by Southern blot
hybridization and GUS expression. Transgenic R2 soybean and lentil plants were also obtained. Segregation ratios in these populations showed a strong bias against transgene
presence or expression. 相似文献

A domain needed for the catalytic efficiency of an enzyme model of simple processivity and domain–domain interactions has been characterized by NMR. This domain 4 from phosphomannomutase/phosphoglucomutase (PMM/PGM) closes upon glucose phosphate and mannose phosphate ligands in the active site, and can modestly reconstitute activity of enzyme truncated to domains 1–3. This enzyme supports biosynthesis of the saccharide-derived virulence factors (rhamnolipids, lipopolysaccharides, and alginate) of the opportunistic bacterial pathogen Pseudomonas aeruginosa. 1H, 13C, and 15N NMR chemical shift assignments of domain 4 of PMM/PGM suggest preservation and independence of its structure when separated from domains 1–3. The face of domain 4 that packs with domain 3 is perturbed in NMR spectra without disrupting this fold. The perturbed residues overlap both the most highly coevolved positions in the interface and residues lining a cavity at the domain interface. 相似文献
