Ultrastructure of Inoculated Anthers in Relation to the Frequency of Induction of Pollen Callus in Anther Culture of Oryza sativa L
Anther Culture Oryza sativa L Rice Ultrastructure
2009/8/6
The formation of pollen callus was induced when rice anthers, which contained microspores in the mid-uninucleate and late-uninucleate stage, were cultured. The ultrastructure of the microspores was al...
Isolation and Culture of Protoplast from Finger Millet(Eleusine coracana)Callus
Cell division Cell wall Finger millet Protoplast isolation and culture
2009/8/5
High yield of protoplast was obtained from the green callus tissue of finger millet at one week after subculture on MS medium with 0.2 mgl-1 2, 4-D and 0.1 mgl-1 kinetin. The protoplasts were release...
