A review of geminivirus diseases in vegetables and other crops in Brazil: current status and approaches for management Horticultura Brasileira
Inoue-Nagata,Alice K; Lima,Mirtes F; Gilbertson,Robert L.
ABSTRACT: Insect-transmitted viruses cause some of the most damaging and economically important diseases of crop plants, especially in tropical and subtropical regions. The geminiviruses, a group of single-stranded DNA viruses with unique twined icosahedral virus particles, are responsible for many of these diseases. Of particular importance are the geminiviruses transmitted by whiteflies (Bemisia tabaci), which are in the genus Begomovirus. This is the largest genus of plant viruses (in terms of number of species), and some are responsible for many devastating diseases in vegetable and fiber crops throughout the world. This review presents the current understanding of begomoviruses, the diseases they cause, and approaches for disease management. An...

Selection of tomato genotypes for processing with high zingiberene content, resistant to pests Horticultura Brasileira
Lima,Isabela P; Resende,Juliano TV; Oliveira,João RF; Faria,Marcos V; Dias,Diego M; Resende,Nathalia CV.
ABSTRACT Tomato cultivars resistant to arthropod pests are an important tool to reduce the use of pesticides. Resistance sources can be found in wild Solanum species such as S. habrochaites, which shows high levels of zingiberene (ZGB). This study aimed to evaluate the resistance of a tomato F2 progeny to spider mite and whitefly by evaluating the ZGB content, in laboratory, in plants from the F2 population of the interspecific crossing Solanum lycopersicum cultivar Redenção x Solanum habrochaites var. hirsutum (PI-127826), F1 plants, susceptible plants (cultivar Redenção) and plants of the wild species (PI-127826). From the F2 population, six plants with high content and three with low content of ZGB were selected. For evaluating the impact of ZGB on the...
