H sub(2)O sub(2) Is Required for Optimal Establishment of the Medicago sativa/Sinorhizobium meliloti Symbiosis

The symbiotic interaction between Medicago sativa and Sinorhizobium meliloti RmkatB super(++) overexpressing the housekeeping catalase katB is delayed, and this delay is combined with an enlargement of infection threads. This result provides evidence that H sub(2)O sub(2) is required for optimal pro...

Zusammenfassung:The symbiotic interaction between Medicago sativa and Sinorhizobium meliloti RmkatB super(++) overexpressing the housekeeping catalase katB is delayed, and this delay is combined with an enlargement of infection threads. This result provides evidence that H sub(2)O sub(2) is required for optimal progression of infection threads through the root hairs and plant cell layers.
