- Title
Anoxia Tolerance in a Root Hair Defective Mutant of Rice.

- Abstract
Anoxia tolerance of rice (Oryza sativa L.) seedlings was investigated using wild type (WT) and root hair defective mutant RH2. The elongation of both RH2 and WT roots was suppressed by anoxia, but this suppression was less in RH2 than in WT roots. The anoxic treatment increased the activity of alcohol dehydrogenase in both RH2 and WT roots, but the induction was greater in RH2 roots. These results suggest that anoxia tolerance of RH2 roots is greater than that of WT roots, indicating that root hairs may interfere with the anoxia tolerance of rice roots.
