Prompt Description

Generate a scientific illustration in the style of a Current Biology graphical abstract, depicting ABA signaling response curves during tomato fruit development under varying PYL receptor overexpression conditions. Main panel: A graph with the x-axis labeled 'Fruit Development Stage (days after flowering) / Endogenous ABA Concentration (increasing over time)' and the y-axis labeled 'ABA Signaling Strength'. Display three distinct sigmoid curves: 1. Wild type / control (PK7, black or gray line): A moderate sigmoid curve with a threshold in the middle, saturating around 38–40 days. Label: 'WT: medium fruit set, medium size, normal ripening (~38–40 days)'. 2. PYL2-OE (dimeric, low basal activity, red, steep line): A curve strongly shifted to the right with a very steep slope, exhibiting switch-like/on-off behavior. The signal is low in early stages, with an explosive rise in late stages. Label: 'PYL2-OE: early low ABA → weak signal → high fruit set, many small fruits (40–50 per plant, ~0.4–0.5 g); late high'
