“…Genetic engineering, with which any genes from any organisms can be utilized, has liberated plant breeding from these previous genetic constrains. Flower color modification with genetic engineering has been reviewed (Chandler and Lu 2005;Tanaka 2006;Tanaka et al 2005;Tanaka and Brugliera 2006) and regulatory and commercial issues of genetically modified floricultural plants have been reviewed (Chandler 2003;Chandler and Tanaka 2007).…”

A broad spectrum of living modified organisms (LMOs) have been developed and commercial production of them have already been started. It is the global requirement to conduct environmental biosafety after the implementation of Cartagena Protocol on Biosafety. Environmental biosafety assessment is of cardinal importance even in confined field trials and at the deliberate release to an environment for practical uses. It is necessary to collect various categories of data prior to fields; not only about the morphological and physiological traits of the LMOs in some confined experimental facilities, but also about characteristics of host organisms in the natural habitat and field for intended releases. Environmental release of LMOs is possible only after collected information is examined systematically and comprehensively in a scientifically-sound manner, and target end-points of such uses are well-identified. Environmental biosafety assessments principally require case-by-case evaluation. Gene-flow, allelopathy and invasiveness are three key aspects in GM plants. In Japan, many crop species do not have their wild relatives due to their historical introduction from overseas. Furthermore, crops grow properly only under agricultural practices, and invasive weediness of these plants is very likely low. In contrast, floricultural plants and trees have related native species located around the fields that can cross with the transgenic counterparts in many cases. In this review, we examine the environmental biosafety assessment of LMO floricultural plants and trees enumerating the example of field trials in Japan, and describe concepts that should be noted for the commercial cultivation and environmental release of these species.

“…Investigation of color formation in a flower is required for orchids breeding programs to improve the quality of the orchids [5][6][7]. It is quite difficult breeding orchid to obtain a new flower color conventionally because of the low probability of getting the desirable colors without changing the flower's other characteristics.…”

Dendrobium helix cv. Pomeo Brown is one of the most attractive species in Spatulata section. This orchid is an epiphyte which has clustered stem, elliptic leaves, and erected flowers with brown petals. The brown color of D. helix cv. Pomeo Brown is due to the anthocyanin. Biosynthetic pathway of anthocyanin is regulated by several enzymes, including key enzyme dihydroflavonol-4-reductase (DFR) which is encoded by DFR gene. This study aimed to analyze the DFR gene from D. helix cv. Pomeo Brown by PCR using primer which were designed based on Dendrobium moniliforme. The sequences amplified using these primers could not be analyzed. Based on the sequence chromatograph, it can be suggested that the amplified DNA consists of several DFR fragments.
