Heat shock (HS) at 40 degrees C was given to the root system of Nicotiana tabacum wild type (WT) and to HSIPT transgenic plants transformed with the bacterial cytokinin biosynthesis gene isopentenyltransferase (ipt) cloned behind the heat shock 70 promoter from Drosophila melanogaster. HS increased cytokinin concentrations in roots and leaves of transgenic plants. The effect was smaller in WT p...

Irradiation of maize (Zea mays) roots and coleoptiles with visible light causes dark-reversible absorbance changes in these organs. There is an increase in absorbance near 440 nanometers and smaller increases below 410 nanometers and about 595 nanometers. Decreases in absorbance are observed at about 420 nanometers and minor ones at 537 and 575 nanometers. These responses are also observed in c...

Complex Multiplication (CM) method is a frequently used method for the generation of elliptic curves (ECs) over a prime field Fp. The most demanding and complex step of this method is the computation of the roots of a special type of class polynomials, called Hilbert polynomials. However, there are several polynomials, called class polynomials, which can be used in the CM method and have much s...
