The retrotransposon-based sequence-specific amplification polymorphism (SSAP) marker system was used to assess the genetic diversities of collections of tomato and pepper industrial lines. The utility of SSAP markers was compared to that of amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) markers. On the basis of our results,(More)
Using a previously described vector (pKL203) we fused several heterologous ribosomal binding sites (RBSs) to the lacZ gene of E. coli and then studied the variation in expression of the fusions. The RBSs originated from bacteriophage Q beta and MS2 genes and the E. coli genes for elongation factor EF-Tu A and B and ribosomal protein L11 (rplK). The(More)
Lettuce (Lactuca sativa) seeds exhibit thermoinhibition, or failure to complete germination when imbibed at warm temperatures. Chemical mutagenesis was employed to develop lettuce lines that exhibit germination thermotolerance. Two independent thermotolerant lettuce seed mutant lines, TG01 and TG10, were generated through ethyl methanesulfonate mutagenesis.(More)
Reverse breeding (RB) is a novel plant breeding technique designed to directly produce parental lines for any heterozygous plant, one of the most sought after goals in plant breeding. RB generates perfectly complementing homozygous parental lines through engineered meiosis. The method is based on reducing genetic recombination in the selected heterozygote(More)
Biochemical characterization in combination with genetic analyses in BC 2 S 1 plants and near-isogenic lines led to the detection and validation of C. baccatum loci affecting flavor, terpenoid content and Brix level. The species Capsicum baccatum includes the most common hot peppers of the Andean cuisine, known for their rich variation in flavors and(More)
A vector (pKL203) was constructed which contains the promoter-operator region of the lacZ gene and the major part of the coding sequence of the lac operon. The lacZ translation initiation signals [Shine-Dalgarno (SD) sequence and AUG codon] were deleted, and in their place a synthetic linker sequence was inserted, providing single restriction sites for SmaI(More)
