DNA binding specificity and cleavage activity of Pacmmar transposase.

Mariner-like elements (MLEs) are members of the Tc1/mariner superfamily of transposable elements which transpose by a "cut and paste" mechanism. Most of the MLEs characterized to date are transpositionally inactive due to the accumulation of mutations in their transposase gene. Here, we report the biochemical study of two copies of the Pacmmar element (Pacmmar1.

Osmotic adjustment, gas exchanges and chlorophyll fluorescence of a hexaploid triticale and its parental species under salt stress.

The effect of salt stress (NaCl 85.7 or 110 mmol/L) was investigated in the triticale T300 and its parental species, Triticum dicoccum farrum (Triticum df) and Secale cereale cv. Petkus.
