Methylation of a MITE insertion in the - Oxford Academic
2022年7月28日 · A miniature inverted-repeat transposable element (MITE) insertion (MITE-MdRF1) in the promoter of MdRFNR1-1, a drought-inducible gene, is methylated and recognized by the MdSUVH–MdDNAJ complex. Methylated MITE-MdRF1 activates MdRFNR1-1 expression and enhances drought tolerance in apple.
Methylation of a MITE insertion in the MdRFNR1-1 promoter is …
2022年9月27日 · Miniature inverted-repeat transposable elements (MITEs) are widely distributed in the plant genome and can be methylated. However, whether DNA methylation of MITEs is associated with induced allelic expression and drought tolerance is unclear. Here, we identified the drought-inducible MdRFNR1 (root- …
A MITE Transposon Insertion Is Associated with Differential Methylation …
2014年3月7日 · MITE insertions can alter methylation at adjacent sites and impact gene expression. MITE transposon insertions such as the one observed at Vgt1 have been repeatedly shown to be associated with QTL for agronomic traits in crops (Guillet-Claude et al. 2004; Magalhaes et al. 2007; Studer et al. 2011; Hou et al. 2012; Zerjal et al. 2012). In most ...
Dynamic changes in transposable element and gene methylation …
MITEs appear to be the main sources of 24-nt siRNAs that regulate gene expression through the RNA-directed DNA methylation pathway. DNA methylation has been proposed to regulate …
A miniature inverted-repeat transposable element (MITE) insertion (MITE-MdRF1) in the promoter of MdRFNR1-1, a drought-inducible gene, is methylated and activates its expression in apple....
(PDF) Methylation of a MITE insertion in the MdRFNR1-1 …
2022年7月28日 · The methylated MITE-MdRF1 is recognized by the transcriptional anti-silencing factors MdSUVH1 and MdSUVH3, which recruit the DNAJ domain-containing proteins MdDNAJ1, MdDNAJ2, and MdDNAJ5, thereby...
[PDF] Methylation of a MITE insertion in the MdRFNR1-1 …
2022年7月28日 · The molecular roles of methylated MITE-MdRF1 in induced MdRFNR1-1 expression as well as the drought response of apple are illustrated and shed light on the molecular mechanisms of natural variation in perennial trees. Miniature inverted-repeat transposable elements (MITEs) are widely distributed in the plant genome and can be methylated.
Methylation of a MITE insertion in the MdRFNR1-1 promoter is …
MdRFNR1-1 but not MdRFNR1-2 expression was significantly induced by drought stress, which was positively associated with the MITE-MdRF1 insertion and its DNA methylation. The …
西北农林科技大学果树逆境生物学团队 - NWAFU
该研究仔细观察 MdRFNR1 的两个等位基因，研究发现在 MdRNFR1-1 的启动子中发现了一个 430 bp 的微型反向重复 TE (MITE) 插入。进一步通过 PCR 基因分型的 371 个 Malus 种质中的 30 个中发现了这种 MITE 插入。
Plant LTR-retrotransposons and MITEs: control of transposition …
2003年6月5日 · Although MITEs cannot be inactivated by TGS, silencing-associated processes, such as methylation, could influence its ability to transpose. Methylation has been shown to modify the capacity of the TIRs of different class II transposons to bind the transposase, and thus influence their transposon competence ( Benito and Walbot, 1997 ; Ros and ...
