SLO2 - Plant Editosome Database - CNCB-NGDC

Summary

Editing Factor: SLO2
Synonym: SLOW GROWTH 2
Description: Loss-of-function mutation in SLO2 results in plant growth retardation, and delayed development, and leads to the dysfunction of mitochondrial complex I, III and IV; This Short Communication discusses the conservation of upstream regions of editing sites affected by SLO2 and illustrates the effect of mutation of SLO2 on activation of the alternative pathway; The slo2 growth retardation phenotypes are largely suppressed by supplying sugars or increasing light dosage or the concentration of CO2; Both the abundance and activity of complex I are highly reduced in the slo2 mutants, as well as the abundance of complexes III and IV; It is proposed that SLO2 is required for carbon energy balance in Arabidopsis by maintaining the abundance and/or activity of complexes I, III, and IV of the mitochondrial electron transport chain
