in this study, the shape and size differences between 30 samples of garra rufa and garra variabilis species captured in tigris river were investigated by using geometric morphometric methods. according to the results of this study, there is no difference between these two species in terms of size (cs); however, they are quite different from each other in terms of shape and this difference is si...

Triangular cells are formed during early logarithmic growth of Trigonopsis variabilis. Good triangularity is obtained with methionine, proline, hydroxyproline, or alanine as a nitrogen source.

Five anabolic and two catabolic enzymes of arginine metabolism were neither repressed nor induced after inclusion of arginine in the growth medium of Anabaena variabilis.

The present study was carried out in order to examine and characterize the bidirectional hydrogenase in the cyanobacterium Nostoc sp. strain PCC 73102. Southern hybridizations with the probes Av1 and Av3 (hoxY and hoxH, bidirectional hydrogenase small and large subunits, respectively) revealed the occurrence of corresponding sequences in Anabaena variabilis (control), Anabaena sp. strain PCC 71...

Synganglia, salivary gland, midgut, ovary, fat body and muscle alone and in combination from the ixodid tick, Dermacentor variabilis (Say), or the argasid tick, Ornithodoros parkeri Cooley, were incubated in vitro in separate experiments with L-[methyl-(3)H]methionine and farnesoic acid or with [1-(14)C]acetate. Life stages examined in D. variabilis were 3 and 72 h old (after ecdysis) unfed nym...

Synganglia, salivary gland, midgut, ovary, fat body and muscle alone and in combination from the ixodid tick, Dennacentor variabilis (Say), or the argasid tick, Omithodoros parkeri Cooley, were incubated in vitro in separate experiments with L-[methyl-3H]methionine and farnesoic acid or with [1-14C]acetate. Life stages examined in D. variabilis were 3-72 hold (after eclosion) unfed nymphs, part...

The quantitative anatomical characteristics of Quercus variabilis virgin cork grown in Korea were observed by scanning electron microscopy and compared with suber reproduction from Portugal to obtain basic data for further utilization domestic resources Korean industries. Q. showed a smaller growth ring width higher latecork percentage than cork. proportion cells lenticular channels suber, wher...
