Resistance gene Cf-9 of cultivated tomato (Lycopersicon esculentum) confers recognition of the AVR9 elicitor protein of the fungal pathogen Cladosporium fulvum. The Cf-9 locus, containing Cf-9 and four homologs (Hcr9s), originates from Lycopersicon pimpinellifolium (Lp). We examined naturally occurring polymorphism in Hcr9s that confer AVR9 recognition in the Lp population. AVR9 recognition occ...

Several properties of the cholinesterase from Phaseolus aureus Roxb. and of pectin (methyl) esterases from both Phaseolus aureus and Lycopersicon esculentum (L.) Mill. are contrasted. Cholinesterase activity is inhibited by all of the concentrations of NaCl tested, from 0.05 m to 0.9 m, a property which differs sharply from published data pertaining to pectin esterase. Although crude preparatio...

The uptake and biotransformation of TNT was studied in cell suspension cultures and in whole plants of Datura innoxia and Lycopersicon peruvianum. In cell culture, TNT was rapidly removed from the growth medium and recovered from the cell extract in the form of a variety of biotransformation products resulting from nitroreduction, deamination, Nacetylation and side chain oxidation to aldehyde a...

S. MANEVA, S., T. VATCHEV and E. MITEVA, 2013. Effect of lead excess in soil on the accumulation of P, K and Na in infected by Fusarium oxysporum f. sp. radicis-lycopersici in tomato (Lycopersicon esculentum Mill.) plants. Bulg. J. Agric. Sci., 19: 972-980 Pot experiments were conducted in greenhouse of IPAZR, “N. Poushkarov”, Sofia, to study the effects of excess lead (Pb) in soils on the upta...

Prolonged infection of tomato hybrid (Lycopersicon esculentum x Lycopersicon peruvianum) by Citrus exocortis viroid (CEVd) resulted in viroid-like enlarged structures, detected by gel electrophoresis. This population included two new enlarged variants or D-variants, D-87 and D-76, and three transient species or D-forms, D-38, D-40 and D-43. Sequence analyses exposed a locus near the terminal re...

this study sought to investigate the effects of two tomato varieties [Lycopersicon esculentum Mill. var. esculentum (Esc) and Lycopersicon esculentum Mill. var. cerasiforme (cEr)] on acetylcholinesterase (AchE) and butyrylcholinesterase (bchE) activities in vitro. Phenolics content, carotenoids characterisation, inhibition of Fe2+ and quinolinic acid-induced malondialdehyde (MDA) production in ...

The lectin of the tomato, Lycopersicon esculentum, or of the potato, Solanum tuberosum, can be passively coupled to amide-modified polystyrene spheres to be used as a detection reagent for the specific identification of group B streptococcal cultures grown in selective or nonselective Todd-Hewitt broth for 5 and 4 h, respectively. Agglutination occurred when the lectin reagents were allowed to ...

The green-fruited Lycopersicon hirsutum Humb. and Bonpi. accumulated sucrose to concentrations of about 118 micromoles per gram fresh weight during the final stages of development. In comparison, Lycopersicon esculentum Mill. cultivars contained less than 15 micromoles per gram fresh weight of sucrose at the ripe stage. Glucose and fructose levels remained relatively constant throughout develop...
