Abstract: 본 발명은 Pr 흡수 스펙트럼이 더 긴 파장으로 이동된 조절된 파이토크롬 A(modified phytochrome A, PHYA) 핵산 분자에 관한 것이다(즉 장파장 또는 적색-이동한).   장파장 파이토크롬을 갖는 식물은 야생형 파이토크롬을 갖는 식물보다 더 큰 효율의 성장 및 발달을 위해 캐노피 및 음지 조건에 반응하는 것이 기대된다(즉 식물에서 음지회피성 반응의 억제).   식물에서 음지회피성 반응은 잎 성장, 저장 기관 생산 및 생식 발달을 희생시켜 잎자루 및 잎꼭지의 신장 성장에서 빠르고 매우 효과적인 증가를 유도하기 때문에 수확률의 상당한 손실을 야기한다.   따라서 음지 광(light)을 효과적으로 이용하는 장파장 파이토크롬은 식물에서 음지회피성 반응을 억제하고 식물에게 음지에 대한 내성을 줄 것이다.   본 발명에서는 몇 개의 장파장 파이토크롬이 식물 PHYA에서 빌린 리아제 도메인(bilin lyase domain) 지역에서 부위 돌연변이 유발(site-directed mutagenesis)에 의해 발생되었고 음지회피성 반응을 억제하는 그들의 능력은 PHYA 부족한 아라비돕시스 탈리아나( Arabidopsis thaliana )(생태형 col-0) 내로 장파장 파이토크롬을 형질전환하는 것에 의해 시험되었다.   장파장 파이토크롬을 갖는 유전자도입 식물은 야생형 식물 및 야생형 파이토크롬을 갖는 유전자도입 식물과 비교하여 증가된 음지내성을 보여주었다.   그러므로 본 발명은 수확률 감소를 유도하는 주요한 원인의 하나인 식물의 그늘회피성을 억제하기 위해 이용될 수 있을 것이고 궁극적으로 높은 수율을 갖는 음지내성 식물을 발생시키기 위해 이용될 수 있을 것이다.   본 발명은 또한 조절된 PHYA를 발현하는 최소한 한 개의 세포를 갖는 식물, 조절된 PHYA 핵산의 최소한 한 부분을 포함하는 벡터 및 음지내성을 갖는 식물을 생산하기 위해 이러한 벡터를 이용하는 방법을 포함한다.
