Antifungal activity and computational study of constituents from Piper divaricatum essential oil against Fusarium infection in black pepper.

Fusarium disease causes considerable losses in the cultivation of Piper nigrum, the black pepper used in the culinary world. Brazil was the largest producer of black pepper, but in recent years has lost this hegemony, with a significant reduction in its production, due to the ravages produced by the Fusarium solani f. sp.

Identifying sequences potentially related to resistance response of Piper tuberculatum to Fusarium solani f. sp. piperis by suppression subtractive hybridization.

Piper tuberculatum is an exotic Piper from the Amazon region that shows resistance to infection by Fusarium solani f. sp. piperis, causal agent of Fusarium disease in black pepper (Piper nigrum L.
