In Vitro Regeneration Of Sandal (Santalum Album L.) From Leaves, Abdul Mujib
In Vitro Regeneration Of Sandal (Santalum Album L.) From Leaves, Abdul Mujib
Turkish Journal of Botany
The first successful induction of adventitious shoot buds on Santalum album L. leaves is reported. De novo shoots were induced directly on leaves without any callusing stage. A leaf length of 0.5-1.5 cm only showed bud inducing potential. Bud formation occurred on both MS and WPM basal media, although, liquid media were more responsive. Among the plant growth regulators, BAP at low concentrations (0.44 and 2.22 µM) was effective in this organogenetic process but exogenous auxin application failed to illicit a similar morphogenetic response. Epiphyllous shoot formation was more pronounced on leaf lamina in which the dorsal and ventral leaf …

Purification And Partial Characterisation Of An Acid Lipase In Germinating Lipidbody Linseedlings, Reda Helmy Ahmed Sammour
Turkish Journal of Botany
Electrophoretic analysis of germinating linseed proteins showed a gradual decrease in the quantity of a protein with a molecular weight of 42 kDa. This protein accumulates after 36 h of germination in synchronisation with an increase in lipase activity, and a decrease in the quantity of the total lipids. The 42 kDa subunit was found to be a lipid body membrane protein. This protein was isolated and identified by immunoprecipitation as a subunit of lipase. The linseed lipase acted on a wide range of triacylglycerols and had optimal activity at pH 4.7. The activity of the enzyme was slightly affected …
In Vitro Mass Propagation Of Cucumis Sativus L. From Nodal Segments, Naseem Ahmad, Mohammad Anis
In Vitro Mass Propagation Of Cucumis Sativus L. From Nodal Segments, Naseem Ahmad, Mohammad Anis
Turkish Journal of Botany
An efficient reproducible protocol for the in vitro multiplication of cucumber (Cucumis sativus L.), an important vegetable crop, was developed from nodal explants. Addition of casein hydrolysate to the shoot induction medium (MS + BA) significantly enhanced the number of multiple shoots or growth of the regenerants. Optimum shoot regeneration was observed on Murashige and Skoog (MS) medium containing 1.0 µM 6-benzyladenine (BA) and (200 mg/l) casein hydrolysate. Rooting of isolated in vitro raised microshoots was readily achieved with (1.0 µM) \alpha-naphthalene-acetic acid (NAA) in 1/2 MS. The plantlets thus obtained were successfully established in a greenhouse.
