Mango anthracnose, caused by Colletotrichum spp., is the most significant disease of mango (Mangifera indica L.) in almost all production areas around world. In Mexico, anthracnose has only been attributed to C. asianum and gloeosporioides. The aims this study were identify species associated with symptoms Mexico phylogenetic inference using ApMat marker, determine distribution these species, test their pathogenicity virulence on fruits. Surveys carried out from 2010 2012 59 commercial...
Developing a comprehensive and reliable taxonomy for the Colletotrichum gloeosporioides species complex will require adopting data standards on basis of an understanding how methodological choices impact morphological evaluations phylogenetic inference. We explored in molecular evaluation associated with banana Brazil. The choice alignment filtering algorithm has significant topological inference retention phylogenetically informative sites. Similarly, marker affects delimitation boundaries,...
Persian lime (Citrus latifolia Tan.) is an important and widely cultivated fruit crop in several regions of Mexico. In recent years, severe symptoms gummosis, stem cankers, dieback were detected the lime-producing region states Veracruz Puebla, The aims this study to identify species Lasiodiplodia associated with these symptoms, determine distribution species, test their pathogenicity virulence on plants. 2015, symptomatic samples collected from 12 commercial orchards, 60 isolates obtained....
Botryosphaeria dieback is an important disease of table grape in the São Francisco Valley, main Brazilian exporting region. The objectives this study were to identify species Lasiodiplodia associated with botryosphaeria grapes investigate prevalence and distribution region, evaluate their pathogenicity virulence green shoots grape. A total 112 isolates obtained from 14 vineyards, located Casa Nova, Juazeiro Petrolina. Fungal identifications made using phylogenetic analysis based on partial...
Phytotoxic metabolites produced in liquid culture by six species of Lasiodiplodia isolated Brazil and causing Botryosphaeria dieback grapevine were chemically identified. As ascertained LC/MS, L. brasiliense, crassispora, jatrophicola, pseudotheobromae jasmonic acid, brasiliense synthesized, besides also (3R,4S)-4-hydroxymellein. euphorbicola hormozganensis some low molecular weight lipophilic toxins. Specifically, (-)-mellein, (3R,4R)-(-)- (3R,4S)-(-)-4-hydroxymellein, tyrosol, synthesized...
Summary. During the last five years a decline of table grape plants has been noticed in nurseries, young planta- tions and vineyards Northeastern region Brazil, where management systems for grapevine production are adapted to specific environmental conditions tropical viticulture. Samples show- ing symptoms were obtained from plantations located Sao Francisco, Assu Siriji Valleys 2010, subjected fungal isolation. Grapevine trunk pathogens identified using morphological molecular methods....
Anthracnose, caused by Colletotrichum musae, is the most important postharvest disease of banana and widely distributed among production regions in Brazil. Although thiophanate-methyl a fungicide frequently used Brazilian orchards to control Sigatoka leaf spot, Collettotrichum populations are also exposed, resulting evolution resistance inability manage anthracnose. We investigated 139 isolates C. musae for sensitivity vitro. The 50% mycelial growth inhibition (EC50) values varied between...
Papaya fruits (Carica papaya L.) (cv. Golden) showing post-harvest anthracnose symptoms were observed during surveys of disease in northeastern Brazil from 2008 to 2012. Fruits affected by showed sunken, prominent, dark brown black lesions. Small pieces (4 5 mm) necrotic tissue surface sterilized for 1 min 1.5% NaOCl, washed twice with sterile distilled water, and plated onto potato dextrose agar (PDA) amended 0.5 g liter-1 streptomycin sulfate. Macroscopic colony characters microscopic...
Abstract In this work, a collection of 94 Macrophomina isolates obtained from roots two weed species, Trianthema portulacastrum and Boerhavia diffusa, collected during surveys conducted 2015 2016 in melon production fields Northeastern Brazil, were characterized by using molecular techniques. Phylogenetic analysis the EF1‐α gene allowed identification 32 as M. phaseolina 62 pseudophaseolina . Results pathogenicity test performed on seedlings cv. “Gladial” revealed that all inoculated able to...
