Isolation, culture, and plant regeneration of protoplasts of two shrubby Oxalis species from south america
Protoplasts were successfully isolated from internodal callus tissues of both Oxalis glaucifolia and O. rhombeo-ovata when they were digested in a solution containing 0.1% (w/v) Macerozyme R-10, 0.5% (w/v) cellulase Onozuka R-10 and 0.3 mmol m-3 sucrose. Protoplasts proliferated to give cell colonie...

| Sumario: | Protoplasts were successfully isolated from internodal callus tissues of both Oxalis glaucifolia and O. rhombeo-ovata when they were digested in a solution containing 0.1% (w/v) Macerozyme R-10, 0.5% (w/v) cellulase Onozuka R-10 and 0.3 mmol m-3 sucrose. Protoplasts proliferated to give cell colonies on Gamborg et al.'s B5 medium supplemented with 0.3 mmol m-3 mannitol, 0.5 mg dm-32, 4-D, and 2.0 mg dm-3 kinetin. Callus was produced upon transfer of cell colonies to Murashige and Skoog medium containing 2.0 mg dm-3 l-naphthaleneacetic acid (NAA) and 0.1 mg dm-3 kinetin for O. glaucifolia, or with 5.0 mg dm-3 NAA and 0.5 mg dm-3 6-benzylaminopurine, for O. rhombeo-ovata. Plants were regenerated from O. glaucifolia protoplasts on a medium containing 0.1 mg dm-3 NAA, 1.0 mg dm-3 kinetin and 1.0 mg dm-3 gibberellic acid, but only vascular nodules were differentiated by O. rhombeo-ovata protoplast-derived calli. © 1989 Oxford University Press. |
