Variability within eight cpDNA introns including trnS-trnfM, trnL-trnT, trnH-psbA, trnF-trnL, trnD-trnT, trnCrpoB, rps16 and matK, and the nuclear waxy introns was examined in seven species of Capsicum (C. annuum, C. baccatum, C. chinense, C. frutescens, C. pubescens, C. chacoense and C. rhomboideum) in order to evaluate the feasibility of utilizing these loci for DNA barcoding within the C. an...

In order to support further genetic, diversity, and phylogeny studies of Capsicum species, the transferability of a Capsicum annuum L. simple sequence repeat (SSR) microsatellite set was analyzed for C. frutescens L. ("malagueta" and "tabasco" peppers) and C. chinense Jacq. (smell peppers, among other types). A total of 185 SSR primers were evaluated in 12 accessions from 115 C. frutescens L. a...

Of the Capsicum peppers (Capsicum spp.), cultivated C. annuum is the most commercially important, but has lacked an intraspecific linkage map based on sequence-specific PCR markers in accord with haploid chromosome numbers. We constructed a linkage map of pepper using a doubled haploid (DH) population derived from a cross between two C. annuum genotypes, a bell-type cultivar 'California Wonder'...

One single pathotype (race 0) was identified among eight tested isolates of Phytophthora capsici (Leonian) collected in northwest Spain, after inoculation tests using pepper cultivars of different origin, including the well known reference resistant cultivar Serrano Criollo de Morelos 334. Complete resistance to P. capsici was not found after the inoculation of 23 local genotypes of Capsicum an...

Pepper (Capsicum spp.) is one of the most cultivated vegetable and spice crops in the world. Capsicum genetics have been extensively studied, but the most recent Capsicum gene list was published more than a decade ago. Since then, new genes have been described. This updated gene list provides detailed descriptions of genes, including the genes characteristics, the genetic background of the muta...

Four pepper genotypes classified as resistant and four pepper genotypes classified as susceptible to several avirulent populations of M. incognita were compared for their reactions against a population of Meloidogyne incognita (Chitwood) Kofoid and White which had been shown to be virulent to resistant bell pepper (Capsicum annuum) in preliminary tests. The virulent population of M. incognita o...

We report a comprehensive proteome analysis of chromoplasts from bell pepper (Capsicum annuum L.). The combination of a novel strategy for database-independent detection of proteins from tandem mass spectrometry (MS/MS) data with standard database searches allowed us to identify 151 proteins with a high level of confidence. These include several well-known plastid proteins but also novel protei...

A range of gas conditions was generated by packing individual capsicums (green ‘Tasty’ bell peppers, Capsicum annuum L.) in packages with different areas of permeable low-density polyethylene film (0.0006–0.48 m) at four different temperatures (0, 12, 20 and 30°C). Steady-state O2 and CO2 partial pressures in the package were used to calculate rates of O2 uptake and CO2 production. The results ...
