Jun 27, 2024 · In these reports, betacyanin and betaxanthin were introduced, and the obtained transgenic plants exhibited a changed color, such as red, purple, and yellow, by the ectopic accumulation of betalain pigments. More recently, a versatile expression system for betalain engineering, called RUBY, has been developed in Arabidopsis and rice . This ...

Feb 1, 2023 · A fast and efficient recognition method of transgenic lines will greatly improve detection efficiency and reduce cost. In this study, we successfully identified the transgenic soybean plants by the color. We isolated a GmW1 gene encoding a flavonoid 3′5′-hydroxylase from a soybean cultivar ZH42 (purple flower). We found that purple flowers ...

Oct 1, 2018 · The genetic engineering of petunia flower color via protoplast transformation is a remarkable example of transgenic ornamental plants (Meyer et al., 1987). However, protoplast culture and plant regeneration is much more difficult and takes substantially longer culture times than tissue culture.

Dec 5, 2018 · In this study, we attempted to modify flower colors by genome editing of a flavonoid biosynthetic-related gene using the basic CRISPR/Cas9 system. For this purpose, we used Torenia fournieri, a model plant widely applied for flower research [20].

A recent overexpression of PhCHS5 and PhF3′5′H genes in petunia and phalaenopsis resulted in deeper floral lip color in both transgenic plants, suggesting the relevance of these genes in phalaenopsis breeding for novel colors .

Transgenic flowers for novel colour are the one in which genes are modified or introduced through genetic engineering and has integrated in its genome for pleasing look. Flower colour is a key element in consumer selection between ornamental varieties available in the market place.

In this chapter, we review recent advances in flower color modification by genetic engineering, especially focusing on the methodology. We have included our own recent results on successful production of flower-color-modified transgenic plants in …

Recent advances in genetic transformation techniques enable the production of desirable and novel flower colors in some important floricultural plants. Genetic engineering of novel flower colors is now a practical technology as typified by commercialization of a …

Flower color is mainly determined by the structure of flavonoids, a group of secondary metabolites of plants. The biosynthetic pathway and the genes involved in the pathway are well characterized such that it is possible to change flower color by engineering the pathway by …

Feb 15, 2019 · Flowers are determined by three classes of pigments: flavonoids, carotenoids and betalains. Flavonoids and carotenoids are widespread; however, betalains can be found only in plants of several...
