Explant Selection, Preparation, and Culturing for Callus Induction.
In experiment B explants (n = 135) were left on MS medium supplemented with 1 mg/l of 2,4D (Alfa Aesar, Haverhill, Massachusetts, USA) and 1 mg/l of BAP (SERVA Feinbiochemica, Heidelberg, Germany) without NPs for 5 weeks to accumulate callus biomass.
Finally, they were subcultured in the same medium every three weeks for six selection cycles until the herbicide resistant callus was formed.
In the same way one does not need to know the precise histological process by which callus forms to remove it, one does not need to know every detail of how a pathological force came to happen to counter it.
After choosing, the experiment was repeated with the four best callus inductor media (CIM), which were called M1, M2, M3, and M4, and subsequently distributed between the different light qualities (white, blue, red, and dark), in the BIM medium for 40 days and 16 hours photoperiod at 25[degrees]C [+ or -] 2.
As a matter of fact, loss of regeneration potentiality or genetic instability is the major constrain in development stable salt-tolerant plants from salt-tolerant callus. Therefore, this present study attempts to produce and develop stable salt-tolerant MR219 plants by screening and selecting salt-tolerant callus line.
