Rice (Oryza sativa) is a highly Al-tolerant crop. Among other mechanisms, a higher expression of STAR1/STAR2 (sensitive to Al rhizotoxicity1/2) genes and of Nrat1 (NRAMP Aluminium Transporter 1), and ALS1 (Aluminium sensitive 1) can at least in part be responsible for the inducible Al tolerance in
We correlated root growth inhibition with aluminium (Al(3+)) localization and toxicity symptoms in rice roots using seedlings of two genotypes (tolerant and sensitive) that were exposed to different AlCl(3) concentrations. Al(3+) localization was evaluated by hematoxylin in primary roots and by
Oryza rufipogon L. (O. rufipogon) or a common wild rice, showed considerable aluminum (Al) tolerance. In this study, we examined the physiologic and genetic response of wild rice short term and long term to Al toxicity, respectively. In the short term study, morin staining, DAPI staining and aniline
