Effects of water deficit on the activity of nitrate reductase and content of su...

The effects of a two weeks soil drying period on the activity of nitrate reductase (NR; EC 1.6.6.6) were studied on Helianthus annuus L. and non-nodulated Lupinus albus L. plants, growing under two nutrient supply regimes. NR activity was assessed in leaf and root extracts, by measuring the activity of the unphosphorylated active form (NRact), the maximal extractable activity (NRmax) and the activation state. T...

Effects of soil drying and subsequent re-watering on the activity of nitrate re...

The effects of drought on the activity of nitrate reductase (NR) were studied in Helianthus annuus L. plants subjected to soil drying and subsequent rewatering. Drought did not negatively affect the activation state of NR, but resulted in linearly correlated decreases in the activity of the unphosphorilated active form and the total activity of NR, both in roots and leaves. The concentration of nitrate in roots...

A reassessment of the anamorphic fungus Fusicoccum luteum and description of it...

When Fusicoccum luteum was first described in 1985, it was not found sporulating in nature and its teleomorph was not known. Recently, a Botryosphaeria sp. was found on grapevines in Portugal, and the anamorph in culture resembled F. luteum. Nucleotide sequence of the nuclear rDNA internal transcribed spacer ITS2 distinguished isolates of this fungus from others in the B. dothidea complex, and the teleomorph, B...
