“…Other karyotype characters frequently observed in species of some Lililaes genera is the bimodality of the karyotyopes (Sanso 2002, Jara-Seguel & Zúñiga 2004, Peruzzi et al 2009). This karyotype character was also observed here for Luzuriaga species.…”

The karyotype of Luzuriaga radicans R. & P. was quantitatively studied, assessing characters such as chromosome morphology and size, satellite location, asymmetry level and bimodality. L. radicans has an asymmetric and bimodal karyotype 2n = 20 with three metacentric pairs, followed by six submetacentric and one subtelocentric chromosome pair. One satellite was observed in the short arm of chromosome pair 6. The total haploid set length was 48.7 µm and the mean chromosome size was 4.87 ± 2.35 µm. Comparing L. radicans with other two species of the genus a high resemblance among their karyotypes was found.

“…Bayer (Alstroemeriaceae) both located between 32°S and 33°S in Central Chile (Buitendijk and Ramanna, 1996;Sanso, 2002), and Lapageria rosea Ruiz & Pav. (Philesiaceae) (Hanson et al, 2003;Jara-Seguel and Zúñiga, 2004). L. rosea inhabits two distinct zones, at 30°S in northern Chile (Fray Jorge National Park) and from 33°S to 40°S in the forests of southern Chile.…”

Chile is located in the south-western region of South America along the Pacific Ocean and contributes to the worldwide flora with ca. 6,120 species of Bryophyta, Pteridophyta, Pinophyta, Gnetophyta, and Magnoliophyta (1.9% of worldwide total species), exhibiting high endemism across all plant divisions. Little is known about the genetic diversity of Chilean land plants worldwide, including their cytogenetic and molecular characteristics. In 2012 we published the first state-of-the-art review in Cytogenetics of Chilean Angiosperms. The article gathered 78 publications from 1924 to 2010 accounting for approximately 139 species (2.8% of total Chilean species). The aim of this paper was to review the advances in cytogenetic studies of Chilean land plants, reporting additional cytogenetic data for species of four botanical divisions until 2020.Cytogenetic data were searched in the CPCD (Chilean Plants Cytogenetic Database). In total, we found 180 publications from both Chilean and foreign researchers. To date, cytogenetic data have been reported for 499 Chilean land plant species (8.2% of total) belonging to 244 genera and 117 families. In this context, the 2001-2020 period has been among the most productive regarding publications, with 74 available reports that include 163 additional species. Based on chromosome numbers, angiosperms and bryophytes registered the greatest diversity with 55 and 29 different 2n, respectively; both divisions having the greatest number of studied species. Given the importance of increasing information on Chilean land plants, it is expected that more publications will contribute to the knowledge of their cytogenetic diversity in the near future.

“…With regard to fB chromosomes, their occurrence in Chilean plants is very low (Jara Seguel and Urrutia, 2012) and their contribution to the ICNH values is negligible. Only one species within the studied dataset (Lapageria rosea) has been described as having B chromosomes (Jara Seguel and Zúñiga, 2004) in six PWA. Moreover, values of fOCN=0 were obtained in all PWA, since there were no species with an odd number of chromosomes across the dataset.…”

Karyotypes of two Colocasia oresbia botanical varieties from Bangladesh were analyzed and compared with orcein, chromomycin A 3 (CMA) and 4´-6 diamidino-2-phenylindole (DAPI).Both varieties had 2n= 2 x = 26 chromosomes (karyotypic formula: 20m+ 6sm) and a pair of satellites each. Total chromosome length was 144.18 ± 2.45 μm in C. oresbia var. oresbia and 133.02 ± 2.75 μm in C. oresbia var. stolonifera. The karyotype of Colocasia oresbia var.oresbia is 2A whereas that of C. oresbia var. stolonifera is 1A. Six CMA and four DAPI bands were observed in C. oresbia var. oresbia and eight CMA and six DAPI bands in C. oresbia var. stolonifera. However, in these two morphologically distinct C. oresbia varieties of two different ecological zones, the same somatic chromosome number, diversification in various karyotypic parameters and CMA/DAPI-banding patterns were observed. In addition to taxonomic characters, the studied karyotype features will contribute to the characterization of these two C. oresbia varieties and to establish a base for future research.

El Cariotipo De Lapageria Rosea Ruiz Et Pav. (Liliales: Philesiaceae)

Abstract: Lapageria rosea Ruiz et Pav. showed an asymmetric and bimodal karyotype 2n = 2x = 30, with three metacentric, six submetacentric and six subtelocentric chromosome pairs. One B chromosome pair was also observed. The total chromosome length (2n) was 131.3 + 0.22 µm.
