  Tall fescue is an open pollinated cool season turf grass. Micropropagation and genetic transformation of monocot species have always experienced low genetic transformation efficiency. Therefore, evaluation of explant types and carbon source in media, likely through callus optimization would lead to the genetic transformation improvement which is the goal of this experiment. After surface sterilization of tall fescue seeds, different seed explants with or without embryo, have used to evaluate callus induction ability. Normal sugar, maltose and equal amount of sugar and maltose were also used as a different source of carbon in a completely randomized design with three replications. Finally, embryogenic calli, induced to produce shoots in MS media supplemented with 10 mg/L 2,4-D and 0.05 mg/L BA. The presence of embryo on explant is a necessity for callus induction. Explant without embryos which were cut differently failed to produce callus. The assessment of three carbon source during the course of multiplication under in vitro culture indicated that sucrose and maltose significantly improved total chlorophyll and carotenoid content in regenerated shoots while MS media with equal amount of both aforesaid carbon sources were not effective. The results gained in the present experiment indicated that embryo-contained cross section of seeds and using maltose was the best explant and the best carbon source for callus induction and shoot proliferation respectively.

  The maltose disaccharide is easily converted into two glucose molecules during cellular glycolysis and is an energy source for sperm motility. To evaluate the effect of maltose on the kinetics of water buffalo epididymal sperm, 10 pairs of buffalo bull testicles, after the usual industrial slaughter, were transported to the laboratory of the Faculty of Veterinary Medicine in a polystyrene box at a temperature of 5o to 8o Celsius. In the laboratory, after fixing the tail of the epididymis with two fingers, several incisions were made in noncapillary zones. After the milky liquid containing concentrated spermatozoa was extracted, this liquid was transferred to an Eppendorf cell culture medium containing 10% bovine serum albumin (BSA). Five levels of maltose sugar (1, 3, 5, 10, 15 mM) were added to the Eppendorf containing 1 ml culture medium and 30-40 million sperm with 10% BSA and incubated at 37o C for 24 hours. Sperm kinetics were assessed at 1, 6, 12 and 24 hours by computer-assisted sperm analysis (CASA). Statistical analysis showed that CASA data such as rapid progressive motility (class A, %), progressive motility (class B, %), viability (class A+B+C, %), straight-line velocity (VSL, µm/s), curvilinear velocity (VCL, µm/s), average path velocity (VAP, µm/s) and lateral head amplitude (ALH, µm) at 24 hrs were higher in the maltose group than in the control group (p<0.05). In conclusion, this study suggests that maltose has a desirable effect on buffalo epididymal spermatozoa and maltose may act as an energy substrate for sperm motility. Manuscript profile
