From: Transcriptomics and co-expression networks reveal tissue-specific responses and regulatory hubs under mild and severe drought in papaya (Carica papaya L.)

Figure 1

Effect of drought stress on papaya plants. (a) Three-month-old ‘Maradol’ papaya plants under control condition (CN) and at 10 and 20 days after stress imposition (DASI). The gradient-colored arrow indicates the intensity of the imposed stress: green = well-watered or no stress, yellow = mild stress, and red = severe stress. White arrows in the plants at 10 DASI indicate leaf wilting. (b–d) Effect of drought stress on papaya plant physiology: (b) CO2 assimilation rate (A), (c) transpiration rate (T), and (d) leaf water potential (Ψ) of the papaya plant depicted in a). Bars and error bars represent means and standard deviation (s.d.), respectively, of three independent plants (n = 3). Different letters indicate statistically significant differences (ANOVA, Tukey p < 0.001).
