a, b Adaxial side of the primary lateral shoot base in a wild-type plant (a) and in an RNAi NtLs knock-down plant (b); c–f Primary lateral shoots of SAS-Ls-1 (c), SAS-Bl-1-1 (e), SAS-ls-1 (d), and SAS-bl1-1 (f) plants; g–i Seedlings of the SAS-rev mutant (g), ‘Coker319′ (h), and Coker319-ls-1 (i); j, k Flowers of Coker319-ls-1 plants; l–n Diagrammatic representation of primary, secondary, and tertiary lateral shoot formation in the leaf axils of SAS-Ls and ls lines (l), SAS-Bl1 and bl1 lines (m), and SAS-REV and rev lines (n). Each column in (l–n) represents a single plant, with each square representing an individual leaf axil. From bottom to top, the squares represent the leaf positions of plants after topping. Red indicates the presence of primary to tertiary (or more) lateral shoots; yellow indicates the presence of primary to secondary lateral shoots; green indicates the presence of only the primary lateral shoot; and white indicates a lack of lateral shoots
