Hairy roots are more sensitive to auxin than normal roots.
Responses to auxin of Lotus corniculatus root tips or protoplasts transformed by Agrobacterium rhizogenes strains 15834 and 8196 were compared to those of their normal counterparts. Three different types of experiments were performed, involving long-term, medium-term, or short-term responses to a synthetic auxin, 1-naphthaleneacetic acid. Root tip elongation, proton excretion by root tips, and ...
متن کاملPhosphate-deprived roots are hypersensitive to auxin.
Low concentrations of phosphate (Pi) in soil trigger alterations to the architecture of the root system that increase a plant’s capacity to absorb Pi. Many plants stimulate the uptake of this essential nutrient by promoting lateral root (LR) formation, increasing root hair length and density (see figure), and suppressing primary root growth. Auxin is a key player in LR development: exogenous au...
متن کاملLong-term Morphine-treated Rats are more Sensitive to Antinociceptive Effect of Diclofenac than the Morphine-naive rats
This study investigates the effectiveness of the antinociceptive effects of diclofenac, an NSAID, on the nociceptive behavior of morphine-treated rats on formalin test.Rats were treated with morphine-containing drinking water for twenty one days, which induced morphine dependence. The antinociceptive effects of 8, 16, and 32 mg/kg doses of diclofenac were then evaluated and compared with distil...

متن کاملPolyprenols in hairy roots of Coluria geoides.
Long-chain polyisoprenoid alcohols built from several up to more than 100 isoprenoid units are common constituents of all living organisms. They were found mostly in plants, bacteria, yeasts and mammalian cells. In vitro hairy root culture of Coluria geoides was obtained from plants transformed with Agrobacterium rhizogenes. Growth was optimal at 0.75% (w/v) glucose and at 22 degrees C. Dry sam...
