In the original article, there was an error in Figure 1 as published. The value of Ψsoil at 33 DAT should be −1.44 MPa. The corrected Figure 1 appears here.
Figure 1.
Dynamics of RSWC and Ψsoil in the well-watered (CK) and drought-stressed tomato seedlings during 27–33 DAT. Mean values and SD were presented (n = 6). ns indicated no significant difference and ** indicated significant difference at P < 0.01 level between drought and well-watered treatment.
The associated text in the Results section Dynamic of Soil Water Status has also been updated to reflect the correction to Figure 1, as described below.
The originally published sentence “By withholding irrigation from 27 to 33 DAT during the progressive drying process, RSWC in the drought treatment decreased gradually from 82.90 to 37.27% and Ψsoil decreased by 1.12 MPa correspondingly.” has been corrected to read “By withholding irrigation from 27 to 33 DAT during the progressive drying process, RSWC in the drought treatment decreased gradually from 82.90 to 37.27% and Ψsoil decreased by 1.04 MPa correspondingly.”
In the original article, there was an error in Figure 3 as published. The value of Ψsoil at 33 DAT should be −1.44 MPa. The corrected Figure 3 appears here.
Figure 3.
Effect of soil water potential (Ψsoil) on the relative contribution of the photosynthesis capacity limiting factors: limitations of An resulting from gs (ls), gm (lm), and biochemical photosynthetic capacity (lb) after transplanting. Data were means. Different letters indicated statistically significant difference between well-watered (CK) and drought plants at P < 0.05 level.
The associated text in the Results section Quantitative Analysis of Photosynthetic Limitation in Response to Soil Drying has also been updated to reflect the correction to Figure 3, as described below.
The originally published sentence “Thirdly, with Ψsoil decreasing to −1.54 MPa, lm contributed to 41.99% reduction in photosynthesis, followed by ls (36.93%) and lb (21.08%), showing that gm was the most important limiting factor to photosynthetic capacity under the severe drought condition.” has been corrected to read “Thirdly, with Ψsoil decreasing to −1.44 MPa, lm contributed to 41.99% reduction in photosynthesis, followed by ls (36.93%) and lb (21.08%), showing that gm was the most important limiting factor to photosynthetic capacity under the severe drought condition.”
In the original article, there were errors in Table 2 as published. Owing to a miscalculation, the values of the parameters were incorrect. The corrected Table 2 appears here.
Table 2.
Sensitivity analyses of the effects of ±20% error of light mitochondrial respiration (Rd), chloroplast CO2 compensation point (Γ*), electron transport rate (Jf), and intercellular CO2 concentration (Ci) on calculation of gm in well-watered and severe drought tomato at Ψsoil = −1.44 MPa as compared with the original value of gm.

Data were mean ± SD (n = 6). ns indicated no significant difference and ** indicated significant difference at P < 0.01 level between drought and well-watered treatment.
The associated text has also been updated to reflect to reflect the correction to Table 2, as described below.
In the Results section Sensitivity Analyses of Parameters in the Estimation gm, the originally published sentence “20% variation of Rd, Γ* did not affect gm significantly (Table 2).” has been corrected to read “10% variation of Rd and Jf did not affect gm significantly, whereas Γ* has a significantly effect on gm in well-watered plants (Table 2).”
In the Results section Sensitivity Analyses of Parameters in the Estimation gm, the originally published sentence “20% underestimation of Ci resulted in an overestimation of gm, while gm was unaffected by overestimation of Ci in both the well-watered and drought treatments.” has been corrected to read “Variation of Ci resulted in an overestimation of gm in well-watered plants, whereas gm in drought treatment was unaffected by overestimation of Ci.”
In the Discussion section Response of gm to Ψleaf and ABA Under Soil Drought, the originally published sentence “However, the sensitivity analyses showed that an overestimation of Ci did not induce gm decline neither in the well-watered nor drought-stressed plants (Table 2).” has been corrected to read “However, the sensitivity analyses showed that an overestimation of Ci did not induce gm decline in drought-stressed plants (Table 2).”
In the original article, there were errors (incorrect P-values) in the following sentence from the Results section Ψleaf and ABA in the Regulation of gs, gm, gt, and An: “In summary, ABA was negatively related to gm (r = −0.64, P < 0.001) and gs (r = −0.55, P < 0.001) (Table 1).” The sentence should have read “In summary, ABA was negatively related to gm (r = −0.64, P < 0.01) and gs (r = −0.55, P < 0.01) (Table 1).”
The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.
