Although the importance of light for tomato plant yield and edible fruit quality is well known, the PHYTOCHROME INTERACTING FACTORS (PIFs), main components of phytochrome-mediated light signal transduction, have been studied almost exclusively in Arabidopsis thaliana. Here, the diversity, evolution and expression profile of PIF gene subfamily in Solanum lycopersicum was characterized. Eight tom...

A new pregnane glycoside, 3-O-beta-lycotetraosyl 5alpha-pregna-3beta,26beta-diol-20-one was isolated from overripe tomato, the fruit of Lycopersicon esculentum MILL.

conclusions the vermicompost as a potential source of plant nutrients for sustainable tomato production can reduce health and environmental problems. results the analysis of the variance results revealed that the effect of the type and amount of fertilizers on tomato yield was significant at 1% level. the results of this study showed that using the vermicompost dosage to cow manure of 500 g/m2 ...

Wild oat is a nuisance monocot weed mainly in cereal canopies. The increasing problem of herbicide resistance and the implementation integrated pest management includes use seed meals from species with allelopathic potential. This study aimed to assess efficacy as an environmentally friendly alternative for control herbicide-susceptible (S) -resistant (R) wild biotypes. A pot experiment was car...

Application of an aqueous solution of aminoethoxyvinylglycine (AVG) ([S]-trans-2-amino-4-(2-aminoethoxy)-3-butenoic acid hydrochloride) to the locular surface of excised 1 cm diameter × 4 mm thick pericarp discs of pre-climacteric, maturegreen tomato (Lycopersicon esculentum Mill., cv. Castlemart) fruit significantly reduced both ethylene and protein biosynthesis in a log-linear fashion. Exposu...

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 ...
