What is micropropagation in potato plants?

Micropropagation is the rapid vegetative propagation of plants under in vitro conditions of high light intensity, controlled temperature and a defined nutrient medium. The technique has been applied to a substantial number of commercial vegetatively propagated plant species. The cost and efficiency of production are the key issues in the commercial micropropagation of potato, and different modes adopted for potato micropropagation have different implications over these issues. In vitro propagation of potato by the serial culture of single-node cuttings (containing axillary buds) has been widely used in the rapid multiplication of disease-free material in elite seed potato programmes (Goodwin et al., 1980 ). The in vitro produced microplants are uniform, true-to-parent type and reliable propagules of choice. They are extensively used by the industry for the production of mini-tubers, almost exclusively in greenhouses, although direct planting into the field can also be employed. In many situations, a relatively low-technology facility can be assembled and utilized – costs can be cut by using generic systems such as supermarket shelving for lighting racks, the use of household sugar rather than laboratory-grade sucrose, replacing distilled water by de-mineralized water and the use of inexpensive food containers as culture vessels. These, although not technically sterile, are produced as food quality items and can reduce operational costs considerably. However, an area that requires careful attention is the matrix used for culture, which, when expensive laboratory-grade agar is used, accounts for more than 75% of the total media cost. Regarding the use of less-expensive agar alternatives, one report cited the use of sago, a processed (gelatinized) edible starch, as a replacement for agar in potato in vitro systems ( Naik and Sarkar, 2001 ), but the economics of this approach need to be determined. Another critical factor is the need for some form of aeration for the growing cultures. The use of cheaper food-grade vessels does not allow proper aeration, so a form of ‘venting’ using micropore-tape may be needed. Several commercial micropropagation companies have devised ingenious systems for carbon dioxide enrichment of the in vitro culture vessels. Additionally, there are low-cost lighting systems on the market. A recent technical report on manipulation of the culture environment on in vitro air movement and its impact on the process of photosynthesis carried out by potato plantlets ( Kitaya et al., 2005) described how enhancement of the air movement in the culture vessel promoted photosynthesis of the in vitro plantlets. Photoautotrophic micropropagation using sugar-free medium is an area of potential utility to scale-up potato micropropagation for commercialization, and recent advancements in the development and utilization of large culture vessels and case studies concerning photoautotrophic micropropagation were described by Zobayed et al. (2004). Manual handling is a major requirement for all conventional micropropagation systems, and it has been estimated that labour costs may represent 65–85% of the total costs; consequently, it has been proposed that the introduction of methods for the automation of specific stages in the whole micropropagation process may assist in reducing total operating costs ( Kondo and Ting, 1998 ). One specific area that may in the future lead to a reduction in the total number of handling steps is the use of aeroponic or bioreactor systems. The use of temporary immersion techniques to enhance production in vitro has been the subject of recent interest and was first reported in potato by Teisson and Alvard (1999) and further advanced by Piao et al. (2003). This methodology has seen widespread uptake in many other species, and this may be an area for further study and refinement in potato.

What is photoautotrophic micropropagation?

Photoautotrophic micropropagation (PAM) narrowly refers to the propagation and growth of explants or plants under disease-free conditions on medium containing no supplemental organic components as nutrients. In PAM or sugar-free medium micropropagation, chlorophyllous explants having photosynthetic ability are used to enhance their photoautotrophic growth. Environmental factors such as light intensity and carbon dioxide concentration need to be properly controlled for promoting photosynthesis of explants and/or plants. Photoautotrophic micropropagation, which improves both the in vitro aerial and root zone environments, significantly promotes the growth of in vitro plants, increases the multiplication rate, and thus shortens the multiplication period of the in vitro stage. Moreover, in vitro plants grown under photoautotrophic conditions show better acclimatization with higher survival rate during the ex vitro stage. As plants, by nature, are considered as photoautotrophic organisms by using inorganic materials existing in the environment to produce carbohydrates for their own need via photosynthetic activity, PAM has recently become a worthy method in commercial plant production in a controlled environment. This chapter reviews the special features of PAM and its practical application over the last decade, and the potential for scaling up large culture vessels to aseptic culture rooms for closed transplant production systems.

What are the limitations of microplants?

To overcome these limitations, the weaning of plantlets under an intermediary ex vitro hardening phase involving conditions of high humidity and reduced light intensity, until the emergence of true and photosynthetically active leaves, is critical to the success of this stage. This hardening phase of microplants requires careful execution to minimize or eliminate losses at this crucial stage of micropropagation. The maintenance of the high health status of the material is paramount, and the microplants are vulnerable at this stage. The use of sterilized media, or non–soil-based substrates, greatly facilitates the avoidance of subsequent pathogen problems. The careful design of the facilities used for these procedures is important, and attention is needed to assure aseptic conditions as far as possible. Many production facilities use protective clothing, filtered air and detailed hygiene procedures, as clearly any contamination at this stage would prove to be costly for the company in terms of loss, or the disruption of production.
