Indole-3-acetic acid를 생산하는 미생물은 어떤 게 있는가? | , 1999; Steenhoudtand Vanderleyden, 2000). IAA를 생산하는 미생물 중에서 홍색 비유황 광합성세균(purple non-sulfur phototrophic bacteria)은 자연계에 널리 분포하고 있고 육상의 토양이나 물이 있는 환경에서 모두 발견되며(Larimer et al., 2004), Rhodobacter capsulatus, Rhodobacter sphaeroids, Rhodopseudomonas faecalis, 그리고 Rhodopseudomonas palustris 등이 IAA를 합성하는 것으로 보고되었다(Song, 2010; Bong, 2017; Sakpirom, 2017). | |
Indole-3-acetic acid란 무엇인가? | Indole-3-acetic acid (IAA)는 천연에서 가장 널리 분포하고 있는 옥신 화합물이며 식물 생장을 조절하고 세포의 신장을 촉진하는 식물 호르몬의 일종이다(Lambrecht et al., 2000). | |
옥신의 역할은? | 많은 Plant growth-promoting bacteria는 IAA 또는 관련 옥신 화합물을 생산하는데(Taghavi etal., 2009), 옥신은 미생물과 식물과의 signaling molecule로서(Spaepen et al., 2007) 식물 뿌리를 자극하여 세포분열과 발근이 촉진되며 줄기와 뿌리의 신장을 유도하여 기주 식물에 의한 토양 양분의 흡수를 증가시키는 것으로 알려져 있다(Dobbelaere et al., 1999; Steenhoudtand Vanderleyden, 2000). |
