چکیده
Combretum micranthum G. Don, also known as kinkéliba, is native to West Africa where the plant grows wild a shrub, liana, or tree and valued for its numerous attributes including health nutritional benefits. Despite this, genetic information commensurate with economic value lacking. The aim of this study was determine nuclear DNA content chromosome numbers C. germplasm from eastern Senegal, Africa. Genome size estimates were determined, first time, number analyzed using actively growing root tips. mean, median, minimum, maximum genome 1587.44 Mb, 1540.85 1472.24 2146.66 respectively. Cytological analysis revealed 2 n = 2x 26. results investigation can be useful structural functional genomics, sequencing endeavors, phylogenic studies well breeding domestication programs.

Cytogenetic characterization and genome size of the medicinal plant Catharanthus roseus (L.) G. Don
BACKGROUND AND AIMS Catharanthus roseus is a highly valuable medicinal plant producing several terpenoid indole alkaloids (TIAs) with pharmaceutical applications, including the anticancer agents vinblastine and vincristine. Due to the interest in its TIAs, C. roseus is one of the most extensively studied medicinal plants and has become a model species for the study of plant secondary metabolism...

reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
New report on chromosome number , karyotype and 4 C DNA content in three species of
Extensive karyotype analysis including determination of somatic chromosome number, total chromosome length and volume and estimation of 4C DNA content were carried out on three species of Pachypodium namely P. lamerei; P. namaquanum and p rosulatum ' horombense' for the first time. A significant variation in nuclear DNA amount was recorded at interspecific level. The somatic chromosome number 2...
متن کاملDNA content of nuclei and chromosome number in sublines of the Ehrlich ascites carcinoma.
The study of metaphase chromosomes of ascites tumors has shown that, for a given strain of tumor, there is found a characteristic modal chromosome number (referred to as «),which frequently lies near that of the diploid number for the host organism (3). Other tumors have modal numbers in the tetraploid range, this condition appearing to enhance the ability of the tumor cells to grow in host st...
متن کاملChromosome number and sex determination coevolve in turtles.
Although much progress has been achieved in understanding the genetic basis of adaptation, the drivers of genome evolution remain obscure. For instance, extensive variation among reptilian genomes continues largely unexplained, yet reptiles hold critical clues about vertebrate evolution. Turtles posses diverse chromosome numbers (2N = 28-66) derived from extensive genomic rearrangements, plus v...
