In silico analysis of effector proteins to elucidate infection strategies of fungal plant pathogens

Senanayaka, S.A.A.R.; Ariyawansa, K.G.S.U. (2020)

Plant pathogenic fungi infect plants to fulfill their nutrient requirements, and this process (pathogenesis) usually leads to disease development. The susceptibility or resistance of host plants against pathogens is partly ...
