Abstract

In plants, color is a powerful tool to attract insects and herbivores which act as pollinators and vehicles of seed dispersion. In particular, flower color has held key post for human with aesthetic value. Horticultural industry has developed methods to produce new and attractive color varieties in flowering plants. Carotenoids are one of the main pigments being responsible for red, orange, and yellow colors. Their biosynthetic pathway has been considered as a major target of metabolic engineering for color modification of flowers and fruits. Here, we review the diverse efforts to modify pigment phenotype by the control of carotenogenic gene expression and enzyme levels. Recent reports about regulating degradation and storage of carotenoids will be also summarized to help the creation of engineered flower with novel color phenotype which is not existed in nature.

식물에서 화색은 종자를 퍼트리기 위해 꽃가루 매개충과 초식동물을 유인하는데 매우 중요한 도구이다. 사람에게 화색은 다채로운 시각적 다양성으로 큰 심미적 가치를 지님으로써 화훼산업의 발전은 새롭고 다양한 매력을 지닌 화색을 생산하는 방향으로 꾸준히 발전되어 왔다. 카로티노이드 성분은 화색 중에서 적색, 홍색, 황색을 나타내는 천연색소로서 이러한 카로티노이드 생합성 경로는 생명공학 기술을 이용하여 화색을 변화시키려는 대사공학의 주된 대상으로 여겨져 왔다. 본 총설에서는 카로티노이드 생합성 대사관련 유전자 발현 조절에 의한 색소 표현형의 변화를 소개하고자 하며, 최근 카로티노이드의 생합성을 넘어 절단과 축적 조절이 화색 변경을 위한 대표적인 기작으로 보고됨에 따라 다양한 화색만큼이나 다양한 조절 기작에 대한 현재까지의 지식을 총 동원하여 원하는 화색을 지닌 인공적인 꽃(engineered flower)을 생산하기 위한 전략을 종합해서 제시하고자 하였다.
