Cloning, subcellular localization, and expression analysis of VvRING1a from grapevine
Jing Feng,Yu Huang,Jiang Lu 한국원예학회 2019 Horticulture, Environment, and Biotechnology Vol.60 No.5
Polycomb group (PcG) proteins within polycomb repressive complex 1 (PRC1) and PRC2 are signifi cant epigenetic regulationfactors involved in controlling plant developmental transitions. PRC2 catalyzes H3K27 trimethylation (H3K27me3),and PRC1 recognizes the site of H3K27me3 and catalyzes H2AK119 monoubiquitination to maintain transcription repression. PRC2 components are conserved from plants to animals and have been investigated for a long time. However, thecompositions and functions of PRC1 vary between animals and plants. Plant PRC1 has only been confi rmed in recent years. Very little research has been conducted on PcG in grapevine ( Vitis vinifera ‘Cabernet Sauvignon’). Here, we cloned the fulllengthcoding sequence of the VvRING1a gene, which is homologous with the Arabidopsis thaliana PRC1 core componentAtRING1a . We then analyzed the structure, subcellular localization, and expression pattern. The tissue-specifi c expressionanalysis showed that VvRING1a is expressed in various tissues, including in roots, stems, leaves, fl owers, buds, and fruits. This study will be a useful reference for further study of VvRING1a .
