(EN) CONTROL OF PLANT FLOWERING TIME BY REGULATING THE EXPRESSION OF PHYTOCHROME C
(KO) 피토크롬C의 발현억제에 의한 식물의 개화시기의 조절
Abrégé
(EN)

It is found out that a rice phyC gene mutant, which is a plant isolated by a method of isolating a mutant with the use of a mutant panel, shows a flowering (earing) time about 1 week earlier than a control in case of growing under long-day conditions. This result indicates that plant flowering can be promoted under long-day conditions by regulating the expression of phyC gene. The promotion of plant flowering with the use of phyC gene can largely contribute to breeding of useful crops or ornamental plants having novel characteristics suitable for cultivation areas or cultivation times, etc. Moreover, a rice phyC gene mutant, the flowering of which is promoted under long-day conditions, is highly expected as a novel rice variety with quickened harvest.

뮤턴트 판넬(mutant panel)을 이용한 돌연변이체의 단리법을 이용하여 단리한 식물인 벼의 phyC 유전자 돌연변이체는, 장일조건에서 키울 경우, 대조군에 비교하여 1주일 정도 개화시기가 빨라지는 것이 발견되었다. 이 결과는, phyC 유전자의 발현을 억제하는 것에 의하여, 장일조건에 있어서 식물의 개화를 촉진할 수 있다는 것을 나타내고 있다. phyC 유전자를 이용한 식물의 개화의 촉진은, 재배지역이나 재배시기에 적응한 새로운 형질을 가지는 유용 농작물이나 관상용 식물 등의 품종의 개량에 크게 공헌할 수 있다. 또, 장일조건에 있어서 개화가 촉진된 벼의 phyC 유전자 돌연변이체는, 수확시기가 빨라진 새로운 벼로서의 이용이 크게 기대된다.
