Photoautotrophic Micropropagation of Rhododendron
Progress in Biotechnology, 2001Co-Authors: Carmen Valero-aracama, Chieri Kubota, S M A Zobayed, Shyamal K. Roy, Toyoki KozaiAbstract:ABSTRACT Photoautotrophic Micropropagation (no sugar in the medium under a controlled environment) has many advantages over conventional photomixotrophic Micropropagation (using sugar-containing medium), such as promoted growth and development of plantlets in vitro and enhanced percent survival ex vitro with many different plant species. Rhododendron is an important ornamental woody species, which often shows low multiplication rates and low percentages of rooting in vitro and survival ex vitro in conventional photomixotrophic Micropropagation, and which could possibly benefit from photoautotrophic culture. In the present study, photoautotrophic culture was investigated during the multiplication and preparation stages of Rhododendron Micropropagation. Based on the results, suitable conditions for obtaining a large number of Rhododendron plantlets with enhanced growth included the absence of plant growth regulators in the medium, a relatively high photosynthetic photon flux, a high CO2 concentration, two-leafed nodal cuttings as explants and full-strength medium. Normal roots were obtained in the absence of plant growth regulators, although the percentages of rooted plantlets were low. Further research is needed to enhance rooting in photoautotrophic Micropropagation.

Horticultural Reviews - Environmental Control and Photoautotrophic Micropropagation
1999Co-Authors: Byoung Ryong Jeong, Kazuhiro Fujiwara, Toyoki KozaiAbstract:The growth and development of chlorophyllous explants, shoots and plantlets in vitro are influenced by aerial and/or physical environmental factors more significantly in photoautotrophic Micropropagation using sugar-free culture medium than in heterotrophic or photomixotrophic Micropropagation using sugar-containing culture medium. It is because, in photoautotrophic Micropropagation, carbon dioxide(CO2) in air is a sole carbon source for increase in dry mass by photosynthesis. Thus, measurement and control of aerial and/or physical environmental factors are essential in photoautotrophic Micropropagation to promote their photosynthesis, growth and development and to reproduce a number of quality plantlets in vitro at low production costs. In this article, methods of environmental measurement and control used in photoautotrophic Micropropagation are briefly discussed. A detailed discussion has been given in Kozai et al. (1995).

The In Vitro Environment and its Control in Micropropagation
Transplant Production Systems, 1992Co-Authors: Toyoki Kozai, Kazuhiro Fujiwara, M. Hayashi, Jenny Aitken-christieAbstract:The reasons for high production costs of micropropagated plantlets are analyzed. Problems requiring solutions by proper control of the in vitro environment for improving shoot/plantlet quality and cost effectiveness are revealed. Features of the in vitro environment and responses of shoots/plantlets cultured in vitro to the environment in conventional Micropropagation are discussed in detail. The features and responses are interpreted from an environmental control point of view. Similarity of growth patterns between plantlets and seedlings under different in vitro environmental conditions is shown. Strategies for environmental control in Micropropagation are discussed. The environmental effect on growth and development of shoots/plantlets cultured in vitro under controlled environments is shown. Advantages and disadvantages of heterotrophic, photomixotrophic and photoautotrophic Micropropagation are discussed. Some novel environmental control systems are introduced.

Plantform Bioreactor for Mass Micropropagation of Date Palm
Methods in molecular biology (Clifton N.J.), 2017Co-Authors: Abdulminam H. A. Almusawi, Abdullah J. Sayegh, Ansam M. S. Alshanaw, John L. GriffisAbstract:A novel protocol for the commercial production of date palm through Micropropagation is presented. This protocol includes the use of a semisolid medium alternation or in combination with a temporary immersion system (TIS, Plantform bioreactor) in date palm Micropropagation. The use of the Plantform bioreactor for date palm results in an improved multiplication rate, reduced Micropropagation time, and improved weaning success. It also reduces the cost of saleable units and thus improves economic return for commercial Micropropagation. The use of the Plantform bioreactor successfully addresses other hindrances that can occur during the scale-up of date palm Micropropagation, including asynchrony of somatic embryos, limited maturation of somatic embryos, and highly variable germination frequencies of embryos.

Micropropagation of Date Palm: A Review
Cell & Developmental Biology, 2015Co-Authors: Mouaad Amine Mazri, Reda MezianiAbstract:Somatic embryogenesis and organogenesis are the two pathways of choice for rapid and large-scale propagation of date palm. They have been successfully used for the Micropropagation of elite genotypes and have proved their effectiveness for the commercial production of many cultivars. Nevertheless, regeneration through somatic embryogenesis or organogenesis in date palm is still difficult to achieve for recalcitrant genotypes and is often hampered by certain physiological disorders. In the present review, we report the results of a number of studies carried out on date palm Micropropagation. It also describes different factors that influence each stage of somatic embryogenesis and organogenesis and the main problems encountered during these two Micropropagation processes.

Micropropagation of Certain Underutilized Fruit Crops
2008Co-Authors: Maneesh Mishra, Ramesh Chandra, Rakesh Tiwari, Rajesh Pati, R. K. PathakAbstract:Abstract Micropropagation is a proven means of producing millions of identical plants under a controlled and aseptic condition, independent of seasonal constraints. It not only provides economy of time and space but also gives greater output and allows further augmentation of elite disease free propagules. India is homeland of many important yet underutilized fruit crops such as Indian gooseberry (Emblica officinalis Gaertn), bael (Aegle marmelos Corr.), jackfruit (Artocarpus hetrophyllus L.), tamarind (Tamarindus indica L.) and jamun or black plum (Syzygium cuminii L. Skeels.). Most of these crops have medicinal value and are suitable for growing under marginal situations. The commercial production of these crops is restricted due to the shortage of desirable planting material. Micropropagation can play an important role in rapidly increasing new cultivars of these fruit crops. This review paper outlines the work done on Micropropagation of these fruit crops.
