Two medicinal plants, O. corniculata and O. triangularis, were investigated cytogenetically for proper characterization. Both plants had Complex Chromocenter interphase nuclei and Continuous prophase chromosomes. O. corniculata was discovered to have 2n=48 chromosomes and 2n=30 in O. triangularis. The chromosomal length range was 0.82±0.02-1.61±0.02 in O. corniculata and 1.02±0.02- 2.52±0.03 in O. triangularis. The total length of the 2n chromosome complement was 53.52±1.19 and 46.76±0.41 for O. corniculate and O. triangular, respectively. The two species differed in centromeric formulas, such as 48m for O. corniculata and 28m+2sm for O. triangularis. In their karyotype, no steady decrease in chromosomal length was seen. These characteristics showed that O. corniculata and O. triangularis could be considered primitive species. Therefore, compiling the cytogenetic features will be helpful to ensure the genuine identification and characterization of the two medicinally important Oxalis species. J. Bangladesh Acad. Sci. 48(1); 135-140: June 2024

“…Hence, the demands of these edible species are increasing day by day as a vital part of the country diet. Even after ongoing analysis of molecular genetics and breeding programs in Allium species, the classical cytogenetical analysis are essential to estimate the numerical and structural features of chromosome set considering karyotype construction to fulfill the increasing needs (Saha et al 2020).…”

Three edible species of Allium, namely, A. sativum, A. cepa and A. tuberosum were cytogenetically investigated to highlight the chromosomal variations among them. These three species of Allium revealed two different numbers of chromosomes with divergent karyotype formula i.e. 2n = 16 = 12m + 4sm in A. sativum, 2n = 16 = 14m + 2sm in A. cepa and 2n = 32 = 28m + 2sm+ 2st in A. tuberosum. A pair of satellite chromosome was found only in A. tuberosum. According to Stebbins’s classification 1B (A. sativum) and 2A (A. cepa and A. tuberosum) type of chromosomal asymmetry were observed. The present cytogenetical analysis revealed that A. cepa was primitive in nature compared to other two species. A. sativum was found to be contemporary to A. cepa and A. tuberosum was more advanced type. Bangladesh J. Bot. 51(2): 353-358, 2022 (June)

“…As cytogenetical analyses are inevitable as they provide important details based on numerical and structural characteristics of chromosome set as to karyotype (Akber et al 2020, Saha et al 2020. Only cytogenetical report highlighting the chromosomal aberration of T. ilisha was carried out in Iraq (Majeed 2016).…”

Tenualosa ilisha (Hamilton, 1822), commonly known as Hilsha shad is a valuable and highly acceptable species in terms of their high flavored properties. Hilsha shad has striking morpho-genetical adaptation to heterogeneous habitats across their migratory routes. Cytogenetic analysis demonstrates the changes in chromosomes. But none was focused on the cytogenetic analysis of T. ilisha in Bangladesh. T. ilisha was found to possess 2n = 42 number of chromosomes along with a karyotype formula: 1M + 31m + 8sm + 2st using giemsa staining technique. The results demonstrated ‘diffuse type of interphase nuclei, co-existence of continuous type and interstitial type of prophase chromosomes respectively. No heteromorphic sex chromosomes were determined cytologically. The presence of diverse types of chromosomes based on centromeric position, gradual decrease in total haploid chromosome complement, mean centromeric asymmetry, coefficient of variation of chromosome length and Stebbins’s classification highlighted its asymmetry in karyotype with advance nature. Therefore, the elemental karyological data will offer information for the proper identification, cytotaxonomical classification, expanding productivity and preservation of genetic resources ofT. ilisha.
