Hybrid seed failure represents an important postzygotic barrier to interbreeding among species of wild tomatoes (Solanum section Lycopersicon) and other flowering plants. We studied genome-wide changes associated with hybrid seed abortion in the closely related Solanum peruvianum and S. chilense where hybrid crosses yield high proportions of inviable seeds due to endosperm failure and arrested ...

Phosphorylation of phosphoenolpyruvate carboxylase (PEPc; EC 4.1.1.31) plays an important role in the control of central metabolism in higher plants. Two PPCK (PEPc kinase) genes have been identified in tomato (Lycopersicon esculentum cv Alicante), hereafter termed LePPCK1 and LePPCK2. The function of the gene products has been confirmed by transcription of full-length cDNAs, translation, and i...

Many plant disease resistance genes (Rgenes) encode proteins characterized by the presence of a nucleotide-binding site (NBS) and a leucine-rich repeat (LRR) region and occur in clusters of related genes in plant genomes. One such gene, Mi-1, confers isolate-speciWc resistance against root-knot nematodes, aphids and whiteXies in cultivated tomato, Solanum lycopersicon. The DNA region carrying M...

The effect of electroplating factory effluent at different dilutions (such as 0.0, 0.10, 0.25, 0.50, 1.00, 1.50, 2.00, 2.50, 3.00, 3.50 and 4.00%) on the germination, growth and nutrient concentration in Tomato (Lycopersicum esculentum) and Egg-plant (Solanum melongena) was studied in an urban soil of Aligarh District of Uttar Pradesh. The results indicated that the germination of both the plan...

Solanum lycopersicum and Solanum tuberosum are agriculturally important crop species as they are rich sources of starch, protein, antioxidants, lycopene, beta-carotene, vitamin C, and fiber. The genomes of S. lycopersicum and S. tuberosum are currently available. However the linear strings of nucleotides that together comprise a genome sequence are of limited significance by themselves. Computa...

The present study aimed to clarify the relationship between sugars and vitamin C in fruit. The objective was to determine whether vitamin C content was regulated by sugar content due to the role of sugar as a precursor for vitamin C. During summer, maximal content in sugar and vitamin C were found in both genotypes tested Solanum lycopersicon 'Cervil' and 'Levovil'. During autumn, fruit pruning...

Wild potato contains about 100 species that are native to the Americas from the southwestern United States to central Chile and adjacent Argentina, Uruguay, Paraguay, and southern Brazil. We report the occurrence of naturalized populations of the wild potato Solanum chacoense in seven sites in southern Australia, eastern China, England, New Zealand, the eastern United States, central Peru, and ...

The effect treatments with the recommended application rates of avermectin, buprofezin, white oil, lambda-cyhalothrin and cyromazine on Trialeurodes vaporariorum Westwood (Aleyrodidae: Homoptera) was evaluated. Pesticides were applied against larvae infesting brinjal (Solanum melongena L.) and tomato (Lycopersicon esculentum Mill) plants in a natural environment of the Cameron Highlands, Pahang...
