Haustoria of parasitic plants have evolved sophisticated traits to successfully infect host plants. The degradation and modification of host cell walls enable the haustorium to effectively invade host tissues. This study focused on two () genes and a set of the cell wall enzyme genes principally expressed during the haustorial invasion of Yuncker. The orthogroups of the TF and cell wall enzyme genes have been implicated in the cell wall degradation and modification activities in the abscission of tomatoes, which are currently the phylogenetically closest non-parasitic model species of species. Although haustoria are generally thought to originate from root tissues, our results suggest that haustoria have further optimized invasion potential by recruiting regulatory modules from other biological processes.
寄生植物的吸器已经进化出复杂的特性以成功感染寄主植物。寄主细胞壁的降解和修饰使吸器能够有效地侵入寄主组织。本研究聚焦于两个（）基因以及一组主要在云克吸器侵入过程中表达的细胞壁酶基因。转录因子（TF）和细胞壁酶基因的直系同源组与番茄脱落过程中的细胞壁降解和修饰活动有关，番茄是目前该物种在系统发育上最接近的非寄生模式物种。尽管一般认为吸器起源于根组织，但我们的结果表明，吸器通过从其他生物学过程中招募调控模块进一步优化了侵入潜力。
