Molecular mechanisms underlying the transition from genetic self-incompatibility to self-compatibility are well documented, but the evolution of other reproductive trait changes that accompany shifts in reproductive strategy (mating system) remains comparatively under-investigated. A notable exception is the transition from exserted styles to styles with recessed positions relative to the anthe...

Meloidogyne hapla Chitwood is among the most serious nematode pests in temperate vegetable crops grown in rotation with potato (Solanum tuberosum L.), a crop with known resistance to potato cyst. While the types of agronomic trait improvements, crops, and pests are limited by resources, preserving improved crops in a rotation system requires understanding their performance against nontarget pes...

Introduction: The larvicidal activity of oils, fatty acids, and methyl esters of Solanum lycocarpum fruit against Culex quinquefasciatus is unknown. Methods: The larvicidal activity of samples of ripe and unripe fruit from S. lycocarpum was evaluated against third and fourth instar larvae of C. quinquefasciatus. Results: The oils, fatty acids, and methyl esters of S. lycocarpum showed the great...

Flowering in tomato (Solanum lycopersicum L.) has long been investigated by plant physiologists and horticulturists aiming to increase productivity of this important fruit crop. The disruption of the sequence of events which give rise to normal development of the reproductive structures by either the manipulation of the environment, hormones or mutations has provided information useful to unrav...

Glandular trichomes from tomato (Solanum lycopersicum) and other species in the Solanaceae produce and secrete a mixture of O-acylsugars (aliphatic esters of sucrose and glucose) that contribute to insect defense. Despite their phylogenetic distribution and diversity, relatively little is known about how these specialized metabolites are synthesized. Mass spectrometric profiling of acylsugars i...

The information and resources generated from diverse "omics" technologies provide opportunities for producing novel biological knowledge. It is essential to integrate various kinds of biological information and large-scale omics data sets through systematic analysis in order to describe and understand complex biological phenomena. For this purpose, we have developed a Web-based system, Plant Me...

Cultivated tomato species develop leaf injury while grown in continuous light (CL). Growth, photosynthesis, carbohydrate metabolism and antioxidative enzyme activities of a cultivated (Solanum lycopersicum L. 'Aromata') and a wild tomato species (Solanum pimpinellifolium L.) were compared in this study aiming to analyze the species-specific differences and thermoperiod effects in responses to C...

Tomato (Solanum lycopersicum) is a model plant of the Solanaceae family. Various biological aspects of tomato have been investigated with molecular biological approaches, and a significant amount of DNA and protein sequencing data on tomato has been accumulated. Recently, the number of tomato genome sequences in the International Nucleotide Sequence Databases has been rapidly increasing due to ...

Growing vegetables economically in the use of constructed wetland for wastewater treatment can play a role in overcoming water and food scarcity. Allium porrum L., Solanum melongena L., Ipomoea aquatica Forsk., and Capsicum annuum L. plants were selected to grow in hybrid constructed wetland (CW) under natural conditions. The impact of the ratio of nitrate to ammonium nitrogen on ammonium and n...
