Chromosome stability of in vitro propagated Cucurbita cultivars

assessment of genetic stability of olive in vitro propagated by rapd marker

the effect of sub culturing frequencies and different cytokinins (benzyl amino purine (bap), 2-isopentenyl adenine (2ip) on genetic stability of micropropagated shoots from olive plant were investigated by using physiological traits and random amplified polymorphic dna (rapd) markers. axillary buds of the olive (cv. dezful) plants were cultured and subcultured in dkw medium, supplemented with b...

The Stability of Variola Virus Propagated in Embryonated Eggs

After 24 transfers in embryonated eggs a strain of variola virus (Chinese) was established in the testis of the rabbit and maintained for 11 passages at intervals of 7 days. Residence in the rabbit testis was not accompanied by any significant alteration in the species identity of the virus. A second strain of variola virus (Minnesota) was transferred 180 times in embryonated eggs with no appar...

Comparisons of in vitro propagation of tomato cultivars

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

High Genetic Stability of Dengue Virus Propagated in MRC-5 Cells as Compared to the Virus Propagated in Vero Cells

This work investigated the replication kinetics of the four dengue virus serotypes (DEN-1 to DEN-4), including dengue virus type 4 (DEN-4) recovered from an infectious cDNA clone, in Vero cells and in MRC-5 cells grown on Cytodex 1 microcarriers. DEN-1 strain Hawaii, DEN-2 strain NGC, DEN-3 strain H-87, and DEN-4 strain H-241 , and DEN-4 strain 814669 derived from cloned DNA, were used to infec...
