Figure 5. Expression profiles of rice PLA superfamily.

Different PLA class expression has been represented by a separate heat map. Reproductive development comprising six stages of panicle [P1 (0–3 cm), P2 (3–5 cm), P3 (5–10 cm), P4 (10–15 cm), P5 (15–22 cm), and P6 (22–30 cm)] and five stages of seed [S1 (0–2 DAP), S2 (3–4 DAP), S3 (4–10 DAP), S4 (11–20 DAP) and S5 (21–29 DAP)]. Clustering of the expression profile was done with log transformed average values taking mature leaf as base line. Three experimental stress conditions are denoted as C: Cold Stress, D: Drought Stress, S: Salt Stress and SL: control, seven day old unstressed seedling. A gene is considered differentially expressed during reproductive development if up- or down-regulated at least two-fold, with respect to the three vegetative controls (mature leaf, root and 7- day old seedling) and with respect to the seven day old unstressed seedling in case of abiotic stress. The color scale at the bottom of each heat map is given in log₂ intensity value.
