الوصف: | The effect of microgravity on the expression of genes for tubulin, stress and aging in Arabidopsis seedlings from wild-type, and the auxinic mutants aux 1 and eir/pin2 is reported. Simulated microgravity was produced through the Random Positioning Machine (RPM). The results showed that the tubulin genes TUA4, TUA6 and TUB2, in plants subjected to μg, showed a peak of expression at 3h in the wild-type, whereas in the mutants it was delayed to 6h. The microgravity treatment tested on the expression of stress genes FeSOD1 and CAT3 showed ony a significant increase of senescence SAG12 showed increased expression in the wild-type starting at 3h, whereas in the mutant a significant increase was seen only at 24h. From the collected data we conclude that auxin transport and action should be involved in tubulin synthesis, stress, and the senescence process. |
