Peptide fraction inhibiting plant pathogen growth predominated in cell wall ext...
Almeida, H. O.; Mattos, E. C.; Barbosa, M. O.; Teixeira, F. R.; Magalhães, R. D. M.; Romeiro, R. S.; Fontes, E. P. B.; Pereira, M. C. BaracatSome varieties of eggplant are little susceptible to some plant pathogens, and antimicrobial peptides (AMPs) could be part of this innate‐defence mechanism. This work aimed to evaluate the in vitro antimicrobial activity of peptide‐enriched fractions from cell wall extracts (CWE) and soluble extracts (SE) from young plants and fully expanded leaves of eggplants against Ralstonia solanacearum and Clavibacter mic...
Bioprospection of cationic and anionic antimicrobial peptides from bell pepper ...
Teixeira, F. R.; Lima, M. C. O. P.; Almeida, H. O.; Romeiro, R. S.; Silva, D. J. H.; Pereira, P. R. G.; Fontes, E. P. B.; Baracat‐Pereira, M. C.Bioprospection of natural compounds to be used as plant protection offers exciting possibilities in agribusiness. ‘Samara’ (SM) and ‘Sunshine’ (SH) cultivars of bell pepper are resistant against some plant pathogens, and leaf antimicrobial peptides could account for their defence system. In the present study, 5–7 kDa peptides were partially purified from cell wall extract (CWE) of bell pepper leaves and further...
Tomato yellow spot virus, a tomato-infecting begomovirus from Brazil with a clo...
Andrade, E. C.; Manhani, G. G.; Alfenas, P. F.; Calegario, R. F.; Fontes, E. P. B.; Zerbini, F. M.Geminiviruses are characterized by a circular, single-stranded DNA genome and twinned icosahedral particles. Begomoviruses (whitefly-transmitted geminiviruses) are a major constraint to crop production worldwide. In Brazil, tomato-infecting begomoviruses emerged as serious pathogens over the last 10 years, due to the introduction of a new biotype of the insect vector. Tomato yellow spot virus (ToYSV) is a newly...
Biological and molecular properties of Tomato rugose mosaic virus (ToRMV), a ne...
Fernandes, J. J.; Carvalho, M. G.; Andrade, E. C.; Brommonschenkel, S. H.; Fontes, E. P. B.; Zerbini, F. M.A viral complex causing golden mosaic and leaf distortion (rugosity) in tomato plants was obtained from viruliferous whiteflies, and named TGV-Ub1. This complex was sap-transmitted from tomato to Nicotiana benthamiana. PCR amplification using universal begomovirus primers yielded two distinct fragments for DNA-A, suggesting that the TGV-Ub1 complex comprised at least two distinct viruses. Clones corresponding t...
