Abstract Pineapple (Ananas comosus var. comosus) fusariosis is an economically important fungal disease affecting the plant and its fruit. A rapid and reliable diagnosis is the base of integrated disease management practices. Fusariosis has resulted in quarantines for pineapple products in Central America, Africa and Asia. Difficulties diagnosing and correctly identifying the fungus Fusarium guttiforme, agent of the pineapple fusariosis, have led to the search for new methodologies, and for this we developed a new reliable molecular method to detect it. For diagnostic purposes, real-time PCR of elongation factor gene 1-α (ef1) was used to rapidly, specifically and sensitively diagnose F. guttiforme. A pathogenicity test was conducted with slips of the...

Biotechnological approaches for plant viruses resistance: from general to the modern RNA silencing pathway
Provedor de dados: 52
Autores: Rodrigues,Silas Pessini; Lindsey,George G.; Fernandes,Patricia Machado Bueno.
Virus diseases are significant threats to modern agriculture and their control remains a challenge to the management of cultivation. The main virus resistance strategies are based on either natural resistance or engineered virus-resistant plants. Recent progress in understanding the molecular mechanisms underlying the roles of resistance genes has promoted the development of new anti-virus strategies. Engineered plants, in particular plants expressing RNA-silencing nucleotides, are becoming increasingly important and are likely to provide more effective strategies in future. A general discussion on the biotechnology of plant responses to virus infection is followed by recent advances in engineered plant resistance.
