| 1 | RNA Polymerase V Functions in Arabidopsis Interphase Heterochromatin Organization Independently of the 24-nt siRNA-Directed DNA Methylation Pathway显示文摘在 Arabidopsis, pericentromeric 重复, retroelements,和 silenced rRNA,基因在作为 chromocenters 知道的原子结构以内被装配进 heterochromatin。管理高顺序的 heterochromatin 组织的机制糟糕被理解但是 24-nt 小介入 RNA (siRNAs ) 被知道在 heterochromatin 起关键作用形成。原子 RNA 聚合酶 IV (Pol IV ) , RNA 依赖的 RNA 聚合酶 2 (RDR2 ) ,并且像骰子(DCL3 ) 3 为 24-nt siRNAs 的生物的续生说被要求有 ARGONAUTE 4 (AGO4 ) 的那个伙伴。原子 RNA 聚合酶 V (Pol V ) 与 DRD1 协作(在 RNA 依赖的 DNA METHYLATION 1 缺乏) 招募在被假设绑在 siRNA-AGO4 建筑群并且随后的包含不同颜色的 loci 产生抄本 de-novo DNA methylation 或 histone 修改机械。这里,我们报导主要 pericentromeric 重复和包含不同颜色的标记 histone H3 离氨酸的弄空的那 decondensation 在 chromocenters 的 9 dimethylation 在 pol V 和 drd1 异种明确地发生。pericentromeric 重复冷凝作用的混乱与 pericentromeric 180-bp 重复的特定的班的 transcriptional 复活是重合的。我们进一步证明 Pol V 独立于 Pol IV, RDR2,和影响分裂期间 heterochromatin 组织的调停 DCL3 的 siRNA 生产工作,可能由包含招募的 RNA 结构或修改染色质的蛋白质。 | Olga Pontes Pedro Costa-Nunes Paul Vithayathil Craig S.
