LecRK-VIII.2 promotes the growth of rosettes, roots, and stems by coordinating the source–sink relationship. A, Rosettes from 35-d-old plants of WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7, bar = 1 cm. B, Roots from 35-d-old plants of WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7, bar = 1 cm. C, Primary stems from 35-d-old plants of WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7, bar = 1 cm (upper panel). Total seeds from each plant of WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7 (bottom panel). D, Relative rosettes size (35-d-old plants, n = 8) of lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7 to WT. Values are means ± SE relative to the WT value that is set at 1. E, Root dry weight per plant of WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7 (82-d-old plants, n = 12). F, Relative stem thickness of lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7 to WT (n = 12). G, Shoot dry weight (without seeds) per plant of WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7 (82-d-old plants, n = 12). H, Total dry weight per plant of WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7 (82-d-old plants, n = 12). I and L, Seed weight to shoot weight ratio (I), seed weight to root weight ratio (J), seed weight to total weight ratio (K), root weight to shoot weight ratio (L). M, Relative size of epidermal cells in rosettes from WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7 (35-d-old plants, n > 100). N and O, Chlorophyll content in rosettes from 35-d-old plants of WT, lecrk-VIII.2-1, lecrk-VIII.2-2, and OE7. FW means fresh weight. Values are means ± SE, n = three biological repeats. The dry weight of shoots and roots was scored after incubation at 80°C for 12 h, while the seed weight was scored after incubation at 37°C for 3 d. Values are means ± SE (E–H, n = 12). *P < 0.05, **P < 0.01 compared with WT (Student’s t test).
