Striga species are obligate root parasitic weeds of cereals, including rain-fed rice, in sub Saharan Africa (SSA). They are the major biotic constraint to cereal production causing yield losses worth > 10 billion US$ annually. Control of Striga is essential for food security and poverty alleviation for small-holder subsistence farmers, but it remains elusive. The use of resistant cultivars is currently limited by a lack of knowledge of the molecular genetic basis of host resistance and parasite virulence.

独脚金属是撒哈拉以南非洲（SSA）谷物（包括雨养稻）的专性根寄生杂草。它们是谷物生产的主要生物制约因素，每年造成的产量损失超过100亿美元。对Striga的控制对于小农户的粮食安全和减贫至关重要，但仍然难以实现。由于对寄主抗性和寄生虫毒力的分子遗传基础缺乏了解，目前限制了抗性品种的使用。
