Transcript Analysis of Pti1a and Pti1b in Rice.

(A) Total RNA was extracted from homozygous and heterozygous pti1a plants and NB. Ten micrograms of total RNA was used for RNA gel blot analysis. The closed arrowhead indicates normal size of Os Pti1a mRNA, and the open arrowhead indicates the size of Os Pti1a with Tos17. Equal loading of RNA samples is shown by the quantity of rRNA.

(B) Expression analysis of Os Pti1a and Os Pti1b was performed with total RNA extracted from seedling root (SR), seedling leaf (SL), adult leaf blade (LB), adult leaf sheath (LS), panicle, not emerged (PnE), and panicle, ripening (PR).
