1. Symptomatology associated with “Purple top”, an emerging disease of solanaceous fruit species
ABSTRACT “Purple top” is an emerging disease that affects solanaceous crops, reported mainly on Solanum tuberosum (potato). Additionally, Bactericera cockerelli has been reported as the insect vector of Candidatus Liberibacter solanacearum (CaLso), a pathogen that has been associated with this disease. However, the information about this disease in Andea

2. InibiÃÃo dos efeitos locais do veneno de Bothrops pauloensis por alcalÃides esteroidais de Solanum campaniforme Roem. &Schult. (Solanaceae). / Inhibition of the local effects of Bothrops pauloensis by steroidal alkaloids from Solanum campaniforme Roem. &Schult. (Solanaceae).
Envenenamentos por serpentes sÃo um importante problema de saÃde muito difundido em paÃses tropicais. Entre as espÃcies mais perigosas da AmÃrica do Sul encontra-se o gÃnero Bothrops. Acidentes ofÃdicos causados por espÃcies Bothrops podem desenvolver rapidamente dano tecidual local grave, incluindo edema, hemorragia, mionecrose, ulceraÃÃo de pele

3. Caracterização química e genética da interação Capsicum spp. (Solanacea), pulgão Aphis gossypii Glover (Hemiptera: Aphididae) e o parasitóide Aphidius colemani Viereck (Hymenoptera, Braconidae, Aphidiinae) / Chemical and genetic characterization of the interaction Capsicum spp. (Solanaceous), Aphis gossypii Glover (Hemiptera: Aphididae) and the parasitoid Aphidius colemani Viereck (Hymenoptera, Braconidae, Aphidiinae)
O controle de pragas das espécies vegetais cultivadas tem sido normalmente realizado por meio de inseticidas, o que é indesejável tanto por motivos econômicos quanto ambientais, já que as aplicações sucessivas afetam os inimigos naturais e aumentam a possibilidade de desenvolvimento de populações da praga resistentes aos inseticidas. Esses problemas

4. Alternative control of Tetranychus evansi Baker & Pritchard (Acari: Tetranychidae) on tomato plants grown in greenhouses
Tetranychus evansi Baker & Pritchard is an important pest of solanaceous plants, including tomatoes. This mite is characterized by a high reproductive rate, which leads to high population growth in a short period of time causing important economic damage. Control of T. evansi is mainly through synthetic acaricides. In searching for environmentally friendly c

5. New hosts of Myrothecium spp. in Brazil and a preliminary in vitro assay of fungicides
Myrothecium roridum and M. verrucaria are two plant pathogenic species causing foliar spots in a large number of cultivated plants. This paper aims to study the causal agents of foliar spots in vegetable crops (sweet pepper, tomato and cucumber), ornamental plants (Spathiphyllum wallisii, Solidago canadensis, Anthurium andreanum, Dieffenbachia amoena) and a

6. Sobrevivência de Ralstonia solanacearum em resto de cultura de pimentão e diferentes tipos de solo de Pernambuco, Brasil
A murcha-bacteriana do pimentão é causada por Ralstonia solanacearum, raça 1, biovares 1 e 3 e causa grandes prejuízos à cultura desta solanácea. Este trabalho teve por objetivo estudar a sobrevivência do patógeno em tecidos infectados de caule e raiz incorporados ao solo às profundidades de 0, 5 e 15 cm; e em 10 diferentes tipos de solo na ausênci

7. Effect of two solanaceous plants on developmental and population parameters of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)
Tuta absoluta (Meyrick) is an important tomato pest that also feeds on other host-plants from the Solanceae family. We studied the effect of two cultivated plants, tomato (Lycopersicum esculentum Mill.) and potato Solanum tuberosum L. on the development and populational parameters of T. absoluta related with host-plant suitability. Larval developmental time,

8. Region VI of cauliflower mosaic virus encodes a host range determinant.
A domain of cauliflower mosaic virus (CaMV) which controls systemic spread in two solanaceous hosts (Datura stramonium and Nicotiana bigelovii) was mapped to the first half of open reading frame 6. Whereas ordinary strains of CaMV are unable to infect solanaceous species except to replicate locally in inoculated leaves, a new CaMV strain (D4) induces chlorot

9. Hybridization of potato spindle tuber viroid to cellular DNA of normal plants*
Molecular hybridization experiments of 125I-labeled potato spindle tuber viroid (PSTV) with DNA from uninfected or PSTV-infected tomato plants showed that infrequent DNA sequences complementary to PSTV exist in both uninfected and infected cells. DNA titration experiments revealed that at least 60% of PSTV is represented by sequences in DNA of several normal

10. A High-Affinity Binding Site for the AVR9 Peptide Elicitor of Cladosporium fulvum Is Present on Plasma Membranes of Tomato and Other Solanaceous Plants.
The race-specific Cladosporium fulvum peptide elicitor AVR9, which specifically induces a hypersensitive response in tomato genotypes carrying the Cf-9 resistance gene, was labeled with iodine-125 at the N-terminal tyrosine residue and used in binding studies. 125I-AVR9 showed specific, saturable, and reversible binding to plasma membranes isolated from leav

11. Specificity in Ecological Interactions. Attack from the Same Lepidopteran Herbivore Results in Species-Specific Transcriptional Responses in Two Solanaceous Host Plants1[w]
Model systems have proven enormously useful in elucidating the biochemical function of plant genes. However their ecological function, having been sculpted by evolutionary forces specific to a species, may be less conserved across taxa. Responses to wounding and herbivore attack differ among plant families and are known to be mediated by oxylipin, ethylene,

12. RNS2: a senescence-associated RNase of Arabidopsis that diverged from the S-RNases before speciation.
Several self-compatible species of higher plants, such as Arabidopsis thaliana, have recently been found to contain S-like RNases. These S-like RNases are homologous to the S-RNases that have been hypothesized to control self-incompatibility in Solanaceous species. However, the relationship of the S-like RNases to the S-RNases is unknown, and their roles in
