dapseq of banana

Ethylene insensitive 3/ethylene insensitive 3-like (EIN3/EIL) are important transcriptional regulators in fruit ripening. Here, we studied the expression of 13 EIL genes during banana fruit ripening, and identified MaEIL9 to be most upregulated in the ripening stage. DAP-seq analysis revealed that MaEIL9 directly targets a subset of genes related to fruit ripening, such as the starch hydrolytic genes MaAMY3D and MaBAM1.

乙烯不敏感蛋白3/乙烯不敏感蛋白3类似蛋白（Ethylene insensitive 3/ethylene insensitive 3-like, EIN3/EIL）是果实成熟过程中关键的转录调控因子。本研究分析了香蕉果实成熟期间13个EIL基因的表达情况，并鉴定出在成熟阶段上调表达最为显著的MaEIL9。DNA亲和纯化测序（DAP-seq）分析结果显示，MaEIL9可直接靶向一类与果实成熟相关的基因，例如淀粉水解基因MaAMY3D与MaBAM1。
