“…Alfalfa leaves turned light green or even yellow with increasing OTC doses. The phytotoxicity might be caused by the inhibition of translational activity of chloroplast and chloroplast (p)ppGpp synthase activity by tetracycline, which is structurally similar to OTC (Bradel et al, 2000;Kasai et al, 2004).…”

“…Hence, there is a potential risk that plants might transfer antibiotics from the soil into the food chain. There are some reports dealing with the effects of antibiotics on plant growth and development (Batchelder, 1981(Batchelder, , 1982Migliore et al, 1998;Bradel et al, 2000;Jjemba, 2002a,b), but information is scant on characterizing the antibiotic uptake into higher plants.…”

Plant uptake of antibiotic oxytetracycline is energy-dependent. AbstractA series of experiments were conducted in a hydroponic system to investigate the uptake of oxytetracycline (OTC) and its toxicity to alfalfa (Medicago sativa L.). OTC inhibited alfalfa shoot and root growth by up to 61% and 85%, respectively. The kinetics of OTC uptake could be well described by MichaeliseMenten equation with V max of 2.25 mmol g À1 fresh weight h À1 , and K m of 0.036 mM. The uptake of OTC by alfalfa was strongly inhibited by the metabolic inhibitor, 2,4-DNP (2,4-dinitrophenol), at pH 3.5 and 6.0, but not by the aquaporin competitors, glycerol and Ag þ . OTC uptake, however, was significantly inhibited by Hg 2þ , suggesting that the inhibition of influx was due to general cellular stress rather than the specific action of Hg 2þ on aquaporins. Results from the present study suggested that OTC uptake into alfalfa is an energy-dependent process.

“…Till today, all the treatments against phytoplasmas have proved ineffective. Tetracyclines are known to have a bacteriostatic effect on phytoplasmas (Davis et al , 1968; Freitag & Smith, 1969; Šarić & Cvjetković, 1985; Bradel et al , 2000; Andersen et al , 2001; Kamińska & Śliwa, 2003). However, symptoms in treated plants would reappear after prolonged growth without the antibiotic, and phytoplasma presence was confirmed by PCR assays.…”

Phytoplasmas are noncultivable bacteria usually maintained in Catharanthus roseus shoots grown in vitro on MS medium with benzylaminopurine. The aim of our research was to examine the influence of indole-3-butyric acid (IBA) on C. roseus shoots infected with three different phytoplasma strains. Supplement of IBA in the medium supported plant growth, photosynthesis and remission of symptoms in all phytoplasma-infected shoots, but had no effect on the presence of EY-C and SA-I phytoplasma strains in tested tissue. However, HYDB phytoplasma was undetectable in approximately half of the tested shoots grown on the medium with IBA. After 1 year of IBA treatment, HYDB-infected periwinkle shoots were retransferred to the medium supplemented with benzylaminopurine. Some of the shoots showing remission of symptoms during the IBA treatment permanently escaped the infection and remained negative when tested for phytoplasma presence. This is the first report on the differential influence of plant growth regulators on phytoplasma-infected C. roseus shoots.

“…Tetracycline antibiotics suppressed disease symptoms of aster yellows (Doi et al, 1967; Davis et al, 1968), sugarcane white leaf (Shikata et al, 1969), Western X‐disease (Amin and Jensen, 1971), Pierce's disease (Hopkins and Martensen, 1971), pear decline (Nyland and Moller, 1973) and apple proliferation (Zawadzka and Kamińska, 1975). More recently, antibiotic treatments caused a remission of symptoms of phytoplasma free‐branching affected poinsettia plants (Bradel et al, 2000) and, in some cases, the symptoms of sudden decline of cabbage trees in New Zealand (Andersen et al, 2001).…”

Effect of Antibiotics on the Symptoms of Stunting Disease of Magnolia liliiflora Plants

Treatment of diseased magnolia plants with Oxytetracycline, Baytril or Tylan did not reduce the number of symptomatic plants, but promoted shoot growth, development of symptomless leaves and flower buds. The most efficient were 500 ppm Baytril, 200 ppm Tylan and 500 or 1000 ppm Oxytetracycline. Lower concentrations of Baytril and Oxytetracycline were less effective and higher concentrations of Tylan decreased the growth of magnolia shoots. All the tested antibiotic treated and untreated magnolias were shown by polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) to contain the AY (16SrI) phytoplasma and two also to contain a phytoplasma related to apple proliferation phytoplasma group (16SrX). The results indicate that Magnolia is a natural host of phytoplasmas belonging to the aster yellows and apple proliferation phytoplasma groups, and support the suggestion that phytoplasmas are the cause of magnolia stunting disease.
