ABSTRACT The population structure of Phytophthora infestans in the Toluca Valley of central Mexico was assessed using 170 isolates collected from cultivated potatoes and the native wild Solanum spp., S. demissum and S. xendinense. All isolates were analyzed for mitochondrial DNA (mtDNA) haplotype and amplified fragment length polymorphism (AFLP) multi-locus fingerprint genotype. Isolate samples...

In the present study, the clastogenic effect of Solanum lycopersicum fruit extract has been evaluated against cyclophosphamide (CP)-induced chromosomal aberrations in the bone marrow cells of the mice. Single i.p. administration of Solanum lycopersicum fruit extract at different test doses, namely 500, 1000 and 1000 mg/kg body weight have provided protection, when given 24 hr prior to the singl...

Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) is a major pest of potato, (Solanum tuberosum L.), tomato (Solanum lycopersicum L.), and peppers (Capsicum spp.). The purpose of our research was to identify and determine the impact of natural enemies on B. cockerelli population dynamics. Through 2 yr of field studies (2009-2010) at four different sites and laboratory feeding tests, we ident...

A major bottleneck to introgressive hybridization is the lack of genome collinearity between the donor (alien) genome and the recipient crop genome. Structural differences between the homeologs may create unbalanced segregation of chromosomes or cause linkage drag. To assess large-scale collinearity between potato and two of its wild relatives (Solanum commersonii and Solanum chacoense), we use...

The endemic and rare Solanum vespertilio and S. lidii from the Canary Islands are notable in being andromonoecious, self compatible, highly heterandrous (with short >reward= anthers and one very long >pollination= anther), and bearing strongly zygomorphic corollas. Solanum vespertilio flowers are also tetramerous, and some display enantiostyly. Given their island distribution, uncommon for sola...

Background & Aim: Solanum anomalum Thonn. ex Schumach. (family Solanaceae) is a shrub growing up to 2 metres tall. The edible fruits are gathered from the wild and consumed locally and the leaves are used locally in the treatment of various diseases. Evaluation of anti-inflammatory activity of leaf extract of Solanum anomalum was carried out to ascertain its uses in t...

General phytochemical screening of the aqueous extract of fruits of Solanum xanthocarpum (Solanaceae) revealed the presence of steroids, terpenes, phenolic compounds, saponins, fatty acids, alkaloids. Fractionation of aqueous extract and activity guided isolation resulted in isolation of two white crystalline powder which were subjected to physical, chemical and spectral identification using IR...

Solanum brasilianum Dunal was described by Dunal in 1813 with reference only to an illustration in an 18th century work by Leonard Plukenet. Th e plate is diffi cult to interpret and no explicitly related specimens were available so the name S. brasilianum has long been regarded as “unresolved” and has never been used. Material matching the Plukenet plate was discovered in the herbarium of the ...
