Biotechnological approaches for improvement of flower crops
Author(s): Bharti Gautam and RK Dubey
Abstract: Unequivocally, horticultural industry has been revolutionized due to contribution by ornamental plants. Flowers and its products are globally traded commodities. Due to rising needs, ornamental plant industry requires new plant varieties with elite traits such as improved anatomical attributes, floral colour, pigments, fragrance and stress tolerance. Therefore, we witness transgenic plant varieties of high aesthetic and commercial value. This century is considered as the era of bio-economy lead by bioscience and biotechnology. Classical breeding strategies for developing new plant lines has some limitations and draw backs i.e. male sterility, degree of heterozygosity etc. Hence, biotechnological approach together with classical breeding methods has been eventually used to modify flower colour, fragrance, appearance of some novel trait, disease resistance etc. Techniques like genetic engineering (GE) has been broadly adopted as more feasible methods to deal with intrinsic obstacles of classical techniques and floral trait modification. Transgenic strategies possess immense potential to produce novel flower phenotypes that are not found in nature. The prime benefit in adopting GE is that any gene from other species gene pool could be introduced in ornamental plants. Achieving a novel flower colour is considered as a chief commercial asset obtained from transgenic plants. Besides this several other commercial traits are also important which enhance the commercial value of flower cops commercially but a little information is available regarding successful transformation of other valuable horticultural characteristics. This review gives a summarized account of the work done on various aspects of floriculture using biotechnological approaches.
