Fluorescent chromosome banding and measurements of nuclear DNA content by image cytometry of Feulgen-stained cells were performed in one sample each of eight diploid (2n = 24) species of Solanum: S. endoadenium, S. argentinum, S. pseudocapsicum, S. atropurpureum, S. elaeagnifolium, S. sisymbriifolium, S. chenopodioides, and S. palustre. The species studied(More)
A total of 106 samples taken from natural Argentinean populations of the weedy Solanum elaeagnifolium (subgenus Leptostemonum) were studied cytologically to understand the impact of the different ploidy levels in its distribution and origin. Classical Feulgen staining was employed to determine mitotic chromosome numbers in all samples. 2C nuclear DNA(More)
Triple staining with the fluorochromes chromomycin A3, distamycin A and 4′-6-diamidino-2-phenylindole (CMA/DA/DAPI) was applied to somatic metaphases and interphase nuclei of 11 taxa of wild chili peppers (Capsicum), with 2n = 2x = 24 (C. annuum var. glabriusculum, C. cardenasii, C. chacoense, C. flexuosum, C. galapagoense, C. eximium, C. praetermissum and(More)
The primary and secondary structures of the intergenic spacer (IGS) between the 3′-end of 25S ribosomal RNA (rRNA) gene and the 5′-end of 18S rRNA gene are described for the cultivated chili pepper Capsicum pubescens. The recognized functional IGS is 2,078 bp in length. According to nucleotide base composition, regulatory elements, and conserved and(More)
