Abstract

In this study, it was aimed to determine the chromosome number of 21 Salvia L. species, to determine chromosome morphology, to reveal karyotype analysis in detail and to contribute to the cytotaxonomy of Salvia. In this context, the results are as follows: (i) the first report for the number of chromosomes of ten species, namely S. corrugata Vahl. (2n = 16), S. curviflora Benth. (2n = 16), S. darcyi J.Compton, S. greggii A.Gray, S. longifolia Nutt., S. vitifolia Benth. (2n = 22), S. subrotunda A.St.-Hil. ex Benth. (2n = 44), S. oppositiflora Ruiz & Pav. (2n = 56), S. stolonifera Benth. and S. atrocyanea Epling (2n = 60); (ii) the karyotypic variations and new chromosome numbers different from previous reports for three species, namely S. cardiophylla Benth. (2n = 36), S. cuspidata Ruiz & Pav. (2n = 44) and S. microphylla Sessé & Moc. (2n = 46); (iii) the same chromosome numbers from previous reports for eight species, namely S. campanulata Wall. ex Benth. (2n = 16), S. elegans Vahl. (2n = 20), S. involucrata Cav., S. mexicana Sessé & Moc. (2n = 22), S. apiana Jeps., S. leucophylla Greene, S. mellifera Greene (2n = 30), and S. splendens Ker Gawl. (2n = 44); (iv) the detailed chromosome measurements and karyotype analyses for all species studied for the first time; (v) the symmetrical karyotypes for all studied species; (vi) the variations resulting from dysploidy or polyploidy and discussing their reasons.

期刊介绍： Caryologia is devoted to the publication of original papers, and occasionally of reviews, about plant, animal and human karyological, cytological, cytogenetic, embryological and ultrastructural studies. Articles about the structure, the organization and the biological events relating to DNA and chromatin organization in eukaryotic cells are considered. Caryologia has a strong tradition in plant and animal cytosystematics and in cytotoxicology. Bioinformatics articles may be considered, but only if they have an emphasis on the relationship between the nucleus and cytoplasm and/or the structural organization of the eukaryotic cell.
