Germplasm Phenotype:

• crr2-1  — Plants display impaired intergenic processing of the polycistronic transcript rps7-ndhB, resulting in no detectable mature form of ndhB mRNA.
• crr2-2  — Plants display impaired intergenic processing of the polycistronic transcript rps7-ndhB, resulting in no detectable mature form of ndhB mRNA.
• crr7-1 crr2-1  — No described phenotype. This line was used to assess the formation of the NDH complex by introducing into this double mutant a transgenic copy of the wild-type CRR7 gene.
