This study aimed to identify Capsicum genotypes with resistance to bacterial spot (BS), anthracnose and Pepper yellow mosaic virus (PepYMV). Fifty-four genotypes of Capsicum spp were evaluated. Resistance reaction against BS was evaluated using three replicates, testing hypersensitivity and quantitative resistance in leaves. After evaluation, inoculated leaves were detached from the plants, bei...

Capsicum baccatum, commonly known as ají, has been reported as a source of variation for many different traits to improve common pepper (C. annuum), one of the most important vegetables in the world. However, strong interspecific hybridization barriers exist between them. A comparative study of two wide hybridization approaches for introgressing C. baccatum genes into C. annuum was performed: i...

The regulatory metabolite, fructose 2,6-bisphosphate (Fru 2,6-P(2)) was found in green pepper (Capsicum annuum L.). The Fru 2,6-P(2) level was found to: (a) rise rapidly in response to heat; (b) drop rapidly, followed by recovery, in response to cold storage of fruit and, (c) oscillate during cold storage of fruit. The possible existence of a relationship between chilling injury and Fru 2,6-P(2...

Obtaining agricultural products with better quality is closely related to the development of new cultivars. New cultivars are increasing gradually internationally as a result breeding programs. Capsicum annuum L. ‘A30706 F1’, ‘Kılçık ‘Bitter F1’ pepper newly developed registered in Turkey. A30706 F1 bitter and black coloured long also called purple coloured, Kılçık sweet thin Bitter hot pepper....

Flow cytometric measurements of nuclear DNA content were performed using ethidium bromide as the DNA stain (internal standard, Hordeum vulgare 'Ditta', 1C = 5.063 pg) in 25 samples belonging to nine diploid species and four varieties of Capsicum: C. chacoense, C. parvifolium, C. frutescens, C. chinense, C. annuum var. annuum, C. baccatum var. baccatum, C. baccatum var. pendulum, C. baccatum var...

The in vitro properties of semi-purified chlorophyllase (chlorophyll-chlorophyllido hydrolase, EC 3.1.1.14) from Capsicum annuum fruits have been studied. The enzyme showed an optimum of activity at pH 8.5 and 50 degrees C. Substrate specificity was studied for chlorophyll (Chl) a, Chl b, pheophytin (Phe) a and Phe b, with Km values of 10.70, 4.04, 2.67 and 6.37 microM respectively. Substrate i...

In the environment, many microorganisms coexist in communities competing for resources, and they are often associated as biofilms. The investigation of bacterial ecology and interactions may help to improve understanding of the ability of biofilms to persist. In this study, the antibacterial and antibiofilm activities of extract Capsicum annuum L on the growth and biofilm formation of common pa...

Chloroplast (cp) genome sequences provide a valuable source for DNA barcoding. Molecular phylogenetic studies have concentrated on DNA sequencing of conserved gene loci. However, this approach is time consuming and more difficult to implement when gene organization differs among species. Here we report the complete re-sequencing of the cp genome of Capsicum pepper (Capsicum annuum var. glabrius...
