Plant non-specific lipid transfer proteins (nsLtps) have been reported to be involved in plant defense activity against bacterial and fungal pathogens. In this study, we identified 135 (122 putative and 13 previously identified) Solanaceae nsLtps, which are clustered into 8 different groups. By comparing with Boutrot's nsLtp classification, we classified these eight groups into five types (I, I...

In the Rosaceae, Scrophulariaceae, and Solanaceae, the stylar product of the self-incompatibility (S-) locus is an RNase. Using protein sequence data from 34 RNase genes (three fungal RNases, seven angiosperm non-S RNases, 11 Rosaceae S-alleles, three Scrophulariaceae S-alleles, and ten Solanaceae S-alleles) we reconstructed the genealogy of angiosperm RNases using the neighbor joining method a...

The SOL Genomics Network (SGN; http://sgn.cornell.edu) is a rapidly evolving comparative resource for the plants of the Solanaceae family, which includes important crop and model plants such as potato (Solanum tuberosum), eggplant (Solanum melongena), pepper (Capsicum annuum), and tomato (Solanum lycopersicum). The aim of SGN is to relate these species to one another using a comparative genomic...

The increasing rate of irreversible damages to natural habitats has reinforced the need for gathering biodiversity fundamental data to conservation. Priority setting is the most important step in protection programs. Solanaceae as the the one of important economic families of eudicots distributed throughout North and South America, Europe, Africa, Asia, Australia, and the South Pacific. Up to n...

Tobacco (Nicotiana tabacum) is a member of the Solanaceae, one of the agronomically most important groups of flowering plants. We have performed an in silico analysis of 1.15 million gene-space sequence reads from the tobacco nuclear genome and report the detailed analysis of more than 2,500 tobacco transcription factors (TFs). The tobacco genome contains at least one member of each of the 64 w...

Knowledge about the distribution of mutational fitness effects (DMFE) is essential for many evolutionary models. In recent years, the properties of the DMFE have been carefully described for some microorganisms. In most cases, however, this information has been obtained only for a single environment, and very few studies have explored the effect that environmental variation may have on the DMFE...

The Solanaceae family includes some important vegetable crops, and they often suffer from salinity stress. Some miRNAs have been identified to regulate gene expression in plant response to salt stress; however, little is known about the involvement of miRNAs in Solanaceae species. To identify salt-responsive miRNAs, high-throughput sequencing was used to sequence libraries constructed from root...

Transcriptional profiling allows for the assessment and comparison of cross-species gene activity and function on a comprehensive scale. The Solanaceae is a large, diverse dicot family, with well-established genetic relationships between major crop species (tomato, potato, pepper, eggplant, and tobacco). Although Arabidopsis thaliana is often the model of choice for anchoring comparative studie...
