Macronutrient deficiency in cucumber plants: impacts in nutrition, growth and symptoms
(2021-01-01)
This study aimed to assess the growth, nutrition and visual deficiency symptoms of cucumber plants as a function of macronutrient omission. The experiment was conducted in a completely randomized design, with seven treatments ...
Modulation of Expression and Activity of ABC Transporters by the Phytoestrogen Genistein: Impact on Drug Disposition
(Bentham Science Publishers, 2016-04)
ATP binding cassette (ABC) transporters are involved in drug absorption, distribution and elimination. They also mediate multidrug resistance in cancer cells. Isoflavones,such as genistein (GNT), belong to a class of ...
