Enhanced SIMR in rcd1 double mutants.

Enhanced SIMR, defined as increased growth defects and/or dwarfism, is observed in the listed rcd1 double mutants. The biological process(es) altered in the mutant crossed with rcd1 is briefly summarized. Of the double mutants used for cell death experiments (Figure 5 and 6) only rcd1 vtc2 displayed enhanced SIMR. In addition rcd1 agb1-2, rcd1 gpa1-4 and rcd1 agb1-2 gpa1-4 displayed leaf characteristics of both parents: round leaves like the G-protein mutants and wavy, bushy leaves like rcd1.
