The histories of crop domestication and breeding are recorded in genomes. Although tomato is a model species for plant biology and breeding, the nature of human selection that altered its genome remains largely unknown. Here we report a comprehensive analysis of tomato evolution based on the genome sequences of 360 accessions. We provide evidence that(More)
Plant heat stress transcription factors (Hsfs) are the critical components involved in mediating responses to various environmental stressors. However, the detailed roles of many plant Hsfs are far from fully understood. In this study, an Hsf (SlHsfA3) was isolated from the cultivated tomato (Solanum lycopersicum, Sl) and functionally characterized at the(More)
The C-repeat (CRT)/dehydration-responsive element (DRE) binding factor (CBF/DREB1) transcription factors play a key role in cold response. However, the detailed roles of many plant CBFs are far from fully understood. A CBF gene (SsCBF1) was isolated from the cold-hardy plant Solanum lycopersicoides. A subcellular localization study using GFP fusion protein(More)
Tomato gray mold disease, caused by Botrytis cinerea, is a serious disease in tomato. Clonostachys rosea is an antagonistic microorganism to B. cinerea. To investigate the induced resistance mechanism of C. rosea, we examined the effects of these microorganisms on tomato leaves, along with changes in the activities of three defense enzymes (PAL, PPO, GST),(More)
Tomato leaf mold is a common disease in tomato cultivation. This disease is caused by Cladosporium fulvum, which has many physiological races and differentiates rapidly. Cf genes confer resistance to C. fulvum, and the C. fulvum-tomato pathosystem is a model for the study of gene-for-gene interactions. Plants carrying the Cf-19 gene show effective(More)
Solanum lycopersicum and Solanum habrochaites are closely related plant species; however, their cold tolerance capacities are different. The wild species S. habrochaites is more cold tolerant than the cultivated species S. lycopersicum. The transcriptomes of S. lycopersicum and S. habrochaites leaf tissues under cold stress were studied using Illumina(More)
In an experimental field, seed vivipary occurred in one accession of tomato rin mutant fruit at approximately 45-50 days after pollination (DAP). In this study, the possible contributory factors to this viviparous germination were investigated. Firstly, developing seeds were freshly excised from the fruit tissue every 5 days from 25-60 DAP. Germination(More)
A total of 30 isolates of Cladosporium fulvum was collected from three provinces (Liaoning, Jilin and Heilongjiang) and the Beijing area in 2013. All isolates were tested on a set of tomato cultivars with differential genotypes against C. fulvum. New races 2.5 and 2.4.5 were identified, which have not been previously reported in China. Race 2.4.9, which had(More)
The transfer of plastid DNA sequences into plant nuclear genomes plays an important role in the genomic evolution of plants. The abundance of nuclear-localized plastid DNA (nupDNA) correlates positively with nuclear genome size, but the genetic content of nupDNA remains unknown. In this mini review, we analyzed the number of nuclear-localized plastid gene(More)
