(A) Diagram of rice plant (left) and rice panicle structure (right). Time course of changes in 13C distribution in the panicle (B); in the flag leaf (C); in the INT1 (D) and in flag leaf sheath and others (determined as pooled organs with these tissues) (E). In panicle structure in (A), superior kernels attached to the same position, where the on-site cell metabolomics was conducted, were displayed with thick lines. Changes in 13C distribution in the superior kernels were also shown (see inset in B). The plants were labeled with 13CO2 for 30 min from the flag leaf at 8 DAH at day time, as indicated by the arrow in (B–E). White and black circles indicate the control and HNT treatments, respectively. Gray areas indicate the HNT treatment. FL, flag leaf; INT1, first internode; LS1, first leaf sheath; L2, second leaf blade. Each point is the mean ± SE of four samples from different plants. * and ** show p < 0.05 and 0.01 by t-test, respectively.
