Fig. 8. Arabidopsis PGY genes encode ribosomal proteins. (A) Schematic representation of PGY1/RPL10aB, PGY2/RPL9C, PGY3/RPL5A genes showing sites of point mutations in pgy1-1, pgy1-2, pgy2-1, pgy3-1 alleles and site of T-DNA insertion in pgy2-2. (B-D) mRNA expression patterns of PGY1 (B), PGY2 (C) and PGY3 (D) in transverse sections of 10-day-old vegetative apices. All three genes are expressed in the meristem and throughout leaf primordia. In older leaves expression is higher in the vasculature and at the margins of the leaf, in cytoplasmically dense cells. Scale bars: 50 µm.
