Effect of culture methods on the regeneration of albino rice (Oryza sativa L.) plantlets.

In our study, we investigated the effects of regeneration conditions on both green and albino rice plants (Oryza sativa L.). The regeneration frequency of an albino cell line was compared to a normal cell line obtained from mature seed under two kinds of culture conditions; namely, the static culture on semi-solid regeneration medium and the suspension culture in liquid regeneration medium. The albino cell line, from which only albino plantlets were regenerated, was induced from the albino leaf segments. There were no significant differences in the regeneration frequencies between normal and albino calli on the semisolid regeneration medium. On the other hand, the frequency of regeneration of albino calli was significantly lower than that of the control specifically in the liquid regeneration medium.
