Orobanche cumana (sunflower broomrape) is an obligate parasitic plant that infects sunflower roots, causing yield losses. Here, by using a map-based cloning strategy, we identified HaOr7-a gene that confers resistance to O. cumana race F-which was found to encode a leucine-rich repeat receptor-like kinase. The complete HAOR7 protein is present in resistant lines of sunflower and prevents O. cumana from connecting to the vascular system of sunflower roots, whereas susceptible lines encode a truncated protein that lacks transmembrane and kinase domains.

受体样激酶增强了向日葵对 Orobanche cumana 的抗性。

Orobanche cumana（向日葵broomrape）是一种专性寄生植物，会感染向日葵根部，导致产量损失。在这里，通过使用基于图谱的克隆策略，我们鉴定了 HaOr7 - 一种赋予对 O. cumana 种族 F 的抗性的基因，该基因被发现编码富含亮氨酸的重复受体样激酶。完整的 HAOR7 蛋白存在于向日葵的抗性品系中，并阻止 O. cumana 连接到向日葵根的血管系统，而易感品系编码缺乏跨膜和激酶结构域的截短蛋白。
