Emerging and re-emerging plant diseases continue to present multifarious threats to global food security. Considerable recent efforts are therefore being channeled towards understanding the nature of pathogen emergence, their spread and evolution. Xanthomonas euvesicatoria pv. perforans (Xep), one of ...
Este estudo avaliou o efeito de diferentes composições de substratos na produção de tubérculos em recipientes. O experimento foi conduzido em casa de vegetação, na Epamig Sudeste (Viçosa, MG), de outubro de 2022 a fevereiro de 2023, com nove tratamentos compostos por solo combinado...
A tiririca-amarela (Cyperus esculentus L. apresenta potencial alimentício e industrial, mas ainda é pouco explorada no Brasil. Este estudo teve como objetivo avaliar a produção de tubérculos em função de diferentes materiais propagativos (tubérculos inteiros, mudas, tubérculos seccionados e escarifica...
Vertical farming offers a controlled environment for food production in regions where land scarcity and environmental stress are prevalent. This study presents a bio-inspired optimization strategy for refining the spectral composition of red, green, and blue (RGB) light from light-emitting diode&...
In 2024, dieback was detected on mango trees in Pernambuco, Brazil, with 40% disease incidence in all areas visited. Three isolates (MP22, MP27 and MP29) were obtained. Based on morphology, cultural and molecular analysis, the causal agent was identified as Diaporthe arecae. Koch's&...
Garlic flowering is agronomically important because it ensures seed production, which is necessary for the reproduction of the species and the generation of new plants. Therefore, the objective of this study was to evaluate the agronomic performance and flowering capacity of garlic geno...
Study shows host species drive PVY evolution. Serial passages of isolates PVYNb and PVYSt in solanaceous hosts revealed that N. benthamiana promotes viral diversification and fitness, while tomato acts as a sink, limiting adaptation. Host-specific mutations underscore virus emergence potential.
BraCTV (Topilevirus) causes curly top disease in Brazilian tomatoes, transmitted by leafhoppers. Study confirms its presence in DF, PE, MT, SC, and SP, with high incidence in SP (79.2%). Symptoms include leaf curling and stunting. Results highlight the need for urgent monitoring and...
Identificou-se uma nova espécie de begomovírus bipartido em tomateiros em Cristalina (GO), nomeada Tomato severe deformation virus (TSDV). Com identidade de ~86% ao ToICV2, causou severa deformação e clorose em testes de patogenicidade (Postulados de Koch), com alta taxa de infecção (87,13%).
Estudo sobre o ToALCV (Topilevirus) no DF. Clone infeccioso confirmou os Postulados de Koch, causando nanismo e clorose. Todas as 15 cultivares testadas foram suscetíveis, incluindo as resistentes a begomovírus. B. tabaci, A. albidula e transmissão mecânica resultaram negativos.
