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 ...

We have studied the induction of gene expression at low temperature by cloning mRNAs that accumulate when unripe tomato (Lycopersicon esculentum) fruit are incubated at 4 degrees C. Two cloned mRNAs, C14 and C17, accumulate relatively rapidly in response to cold treatment, while a third, C19, displays a delayed response. Significant levels of these mRNAs were not detected during fruit ripening ...

two-spotted spider mite (tssm) is becoming resistant to many of the pesticides used in the tomatofields. a potential alternative method of control is host plant resistance, which may be mediated byglandular trichomes. in this experiment, level of entrapment and mortality of the pest by type ivglandular trichomes were studied on accessions of lycopersicon hirsutum humb & bonpl, l. pennellii(cor....

We investigated whether lines of transgenic tomato (Solanum lycopersicum) expressing the Bs2 resistance gene from pepper, a close relative of tomato, demonstrate improved resistance to bacterial spot disease caused by Xanthomonas species in replicated multi-year field trials under commercial type growing conditions. We report that the presence of the Bs2 gene in the highly susceptible VF 36 bac...

The complete mRNA sequence of one tobacco (nicotiana tabacum) gene—guanosine monophosphate (GMP)synthase, was amplified using the rapid amplification cDNA ends methods. full-length GMP synthase gene 2,127bp containing a 1,617 bp open reading frame, which encodes protein 538 amino acids. Sequence analysis revealed that shares high homology with wood tobacco(99%), nicotiana attenuata(99%), toment...

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...

In the past, a classical map of the tomato genome has been established that is based on linkage data from intraspecific Lycopersicon esculentum crosses. In addition, a high density molecular linkage map has recently been constructed using a L. esculentum x L. pennellii cross. As the respective maps only partially match, they provide limited information about the relative positions of classical ...
