Global InformationPhotoautotropic tissue culture information
Photoautotrophic tissue culture is defined as "micropropagation without sugar in the culture medium, in which the growth or accumulation of carbohydrates of cultures is dependent fully upon photosynthesis and inorganic nutrient uptake".[1]
There are multiple advantages to using this form of propagation, because this system actively encourages plant growth. Namely, there are lower contamination rates due to the lack of sugar in the growing medium, and more catering to plants that aren't able to be successfully multiplied by conventional means. Many plants have trouble being propagated to due physiological or morphological inhibitions that make root formation difficult from cuttings. And after the plantlet develops in vitro, then the ex-planting process can often be very stressful and result in plant death, which isn't a problem for pre-acclimated plantlets grown via photoautotrophic tissue culture (In this context, pre-acclimated refers to plantlets that have developed a cuticle and have been cultivated in an open air system as opposed to the closed system seen in typical operations).
