Floral Induction and Flower Development of Orchids.

Area of Science:

• Botany
• Plant Molecular Biology
• Horticulture

Background:

• Orchids are a large, highly evolved angiosperm family, valued in horticulture as potted plants and cut flowers.
• Orchid flowering is influenced by environmental cues (e.g., temperature) and internal genetic programs.
• Floral transition involves floral meristem maintenance and organ specification, crucial for flower development.

Purpose of the Study:

• To review recent research on orchid floral transition and flower development.
• To emphasize key genes and genetic networks involved in these processes.
• To showcase applications of molecular breeding and biotechnology in manipulating orchid flowering.

Main Methods:

• Literature review consolidating recent scientific progress.
• Emphasis on molecular and genetic mechanisms.
• Case studies of successful biotechnological interventions.

Main Results:

• Advances in molecular and genetic technologies have significantly improved understanding of orchid flowering.
• Key genes and genetic networks regulating floral transition and development have been identified, particularly in *Phalaenopsis*, *Dendrobium*, and *Oncidium*.
• Molecular breeding and biotechnology tools offer effective strategies for controlling orchid flowering and flower development.

Conclusions:

• Understanding orchid flowering mechanisms is advancing rapidly due to molecular research.
• Targeted manipulation of flowering is achievable through modern breeding and biotechnological approaches.
• These advancements hold significant potential for the orchid horticultural industry.
