Cilj istraživanja bio je utvrditi alelopatski potencijal lucerne (Medicago sativa L.) na klijavost sjemena i rast klijanaca rotkvice (Raphanus sativus L.), radiča (Cichorium intybus L. var. foliosum) rajčice (Lycopersicon esculentum Mill.). Vodeni ekstrakti pripremljeni od suhe nadzemne mase u tri koncentracije (1 %, 2,5 % 5 %) testirani su laboratorijskim uvjetima. Alelopatski ovisio o test vr...

Extracts of style, petal, leaf, petiole, stem, and callus derived from stems of wild tomato (Lycopersicon peruvianum) contain characteristic sets of arabinogalactan-proteins. This is demonstrated by crossed electrophoresis in which Yariv reagent, which specifically binds to and precipitates arabinogalactan-proteins, is incorporated into the second gel.

Chimeric genes containing a pollen-specific promoter from tomato (Lycopersicon esculentum) or the CaMV35S promoter were transiently expressed following their introduction into tobacco (Nicotiana tabacum) pollen using high velocity microprojectiles. Transient expression of the microprojectile-introduced genes in leaves and pollen was similar to that observed for these genes in stably transformed...

Population genetics theory predicts that strong selection for rare, beneficial mutations or against frequent, deleterious mutations reduces polymorphism at linked neutral (or weakly selected) sites. The reduction of genetic variation is expected to be more severe when recombination rates are lower. In outbreeding species, low recombination rates are usually confined to certain chromosomal regio...

In the tomato (Lycopersicon esculentum) plant, the fruit juice was found to be the richest source of agglutinating activity. The lectin responsible could be inhibited by oligomers of N-acetylglucosamine, and this property was exploited to purify the lectin by affinity adsorption on trypsin-treated erythrocytes. The lectin is a glycoprotein that cross-reacts immunologically with the lectin from ...

Eight wild tomato species are native to western South America and one to the Galapagos Islands. Different classifications of tomatoes have been based on morphological or biological criteria. Our primary goal was to examine the phylogenetic relationships of all nine wild tomato species and closely related outgroups, with a concentration on the most widespread and variable tomato species Solanum ...
