The efficiency of mitochondrial DNA markers in constructing genetic relationship among Oryx species
To date, only parts of mitochondrial DNA from cytochrome b, 12S rRNA, 16S rRNA and non-coding D-loop had been sequenced for different species ofOryx. Discrepancy in the genetic relationship among Oryx species was previously revealed when combinations of these sequences were analyzed. In the present study, various combinations of these data sets and different sampling sizes of the closely related...

Defense responses in tomato fruit induced by oligandrin against Botrytis cinerea
Oligandrin is known to induce resistance against a number of plant diseases. However, its effects on postharvest diseases are still unclear. The effects of oligandrin on the control of postharvest diseases in tomato fruit and its underlying mechanisms were investigated in this study. The treatment of tomato fruit with oligandrin (10 μg/ml) significantly reduced the incidence and severity of gray mould (caused...

Somatic embryogenesis and plantlet regeneration from protoplast culture of Muscari neglectum Guss
A protocol has been developed for plant regeneration from protoplast culture of Muscari neglectum using regenerable embryogenic calli obtained from bulb culture on Murashige and Skoog medium (MS) plant growth regulators (PGR)-free or containing lower 1-naphthaleneacetic acid (NAA) and 6-benzylaminopurine (BA) concentrations and 30 g/l sucrose. Protoplasts were isolated directly from embryogenic calli, embedded in...
