DRM1 and DRM2 expression regulation: potential role of splice variants in response to stress and environmental factors in Arabidopsis

Abstract: The DRM1/ARP gene family is increasingly exhibiting associations with stress conditions at the transcript level. Traditionally correlated with dormancy, increases in transcript levels in response to various treatments have also been reported in various species. As alternative transcript splicing is common in stress conditions, the splice variants of AtDRM1 and AtDRM2 were assessed further in this study. A previously undescribed splice variant of AtDRM1 (AtDRM1.6) is introduced in this work. In silico analyses … Show more

“…We explored the similarities between dormancy and GPA: gene expression changes from growing to arrested meristems and vice versa are consistent with the idea that GPA represents a shoot dormancy. For example, two of the genes with highest gene expression changes during GPA are the AtDRM1 and AtDRM2 genes, considered markers for dormant axillary buds (Tatematsu et al, 2005;Rae et al, 2014). Furthermore, genes responding to ABA, which have recently been proposed to regulate axillary bud growth (Yao and Finlayson, 2015), are strongly up-regulated during GPA.…”

“…이러한 결과는 현사시나무의 PagDRM1 유전자가 건조와 염 스트레스에 반응하여 발현 이 증가함을 의미한다. 염과 건조 처리에 의한 DRM 유전자의 발현 증가는 애기 장대(AtDRM1.1, AtDRM2)에서도 보고된 바 있다 (Rae et al 2014). 또한 배추의 BrDRM1 (Lee et al 2013)과 땅콩의 AhDRM1 유전자도 염과 건조에 의해 발현이 증가하는 것으로 나타 났다 (Govind et al 2009).…”

“…완두콩의 PsDRM1은 본 연구결 과와 유사하게 ABA에 의해 발현이 증가하지만 GA에 대해 서는 반응하지 않았다 (Stafstrom et al 2000). 그러나 애기장 대의 AtDRM1.2와 AtDRM1.4는 GA에 의해 발현이 감소하는 것으로 나타났다 (Rae et al 2014). 따라서 GA 처리에 따른 PagDRM1 유전자의 반응은 다른 식물에서 보고된 DRM 유 전자의 발현특성과는 차이가 있는 것이다.…”
