Eggplant ( L.) is the third most important crop in the family of Solanaceae. Prickles are considered as the undesirable traits during the plantation of eggplant and the transportation of fruits. In this study, we constructed a high-quality genetic linkage Bin map derived from the re-sequencing analysis on a cross of a prickly wild landrace, 17C01, and a cultivated variety, 17C02. The major quantitative trait locus (QTL) controlling the development of prickles on the calyx (explained 30.42% of the phenotypic variation), named as , was identified on a ~7 kb region on chromosome 12. A gene within , which encodes a WUSCHEL-related homeobox-like protein, with higher expression levels in 17C01 calyx and 22-bp deletion in 17C02 was probably the functional gene for prickle formation. Results from this study would ultimately facilitate uncovering the molecular regulatory mechanisms underlying the development of a prickle in eggplant.
茄子（L.）是茄科中第三重要的作物。刺被认为是茄子种植和果实运输过程中不受欢迎的性状。在本研究中，我们通过对多刺野生地方品种17C01和栽培品种17C02的杂交进行重测序分析，构建了一个高质量的遗传连锁Bin图谱。在12号染色体上一个约7 kb的区域内，鉴定出了控制花萼上刺发育的主要数量性状位点（QTL）（解释了30.42%的表型变异），命名为 。 内的一个基因编码一种与WUSCHEL相关的类同源异型盒蛋白，在17C01花萼中表达水平较高，在17C02中存在22-bp缺失，该基因可能是刺形成的功能基因。本研究结果最终将有助于揭示茄子刺发育的分子调控机制。
