Phenotype of P2MH Carrying a G373E Mutation in the RBP-P Gene.

(A) Morphology of the wild type, P2MH (homozygous P2 mutant), and P2N (background genotype carrying normal RBP-P isolated from the heterozygous P2 mutant) during vegetative growth. The P2MH mutant is dwarf, has chlorophyll-deficient leaves, and produces fewer tillers than the wild type.

(B) Direct comparison of the leaf blades of P2MH and P2N with the wild type. Box shows an enlarged image of a region of the P2MH leaf.

(C) P2MH mutant showed late development of reproductive organs. When grains produced by wild-type and P2NH plants started to mature (turn brown), P2MH just began to “flower.”

(D) and (E) Comparison of the tassels from the wild type, P2N, and P2MH. (E) is an enlarged view of the area enclosed in a rectangle in (D).

(F) Severe flowering defect in P2MH. Due to the abnormal development of flower structure, P2MH failed to produce grains. Bar = 1 cm.
