Wani Sabon Fata a Yaƙin Cutar Kwayar cuta ga Dankali

A team of at least 13 scientists from USA, France, Saudi Arabia and Great Britain recently released a paper that brings another new hope for potato growers around the world in their battle against Phytophthora infestans.

The oomycete Phytophthora infestans is a damaging crop pathogen and a model organism to study plant-pathogen interactions. The fungus-like microorganism causes global crop damage amounting to around USD6bn each year and threatens food security.
