Figure 5. Relative transcript levels of CitSus1-6 in mature leaves in response to dehydration (A) and in fruit segment membrane (B) and juice sacs (C) in response to mild drought stress.

Bars marked with lower-case letters indicate that the expression levels showed significant difference at P<0.05 by using Duncan's test. Asterisk (*) on bars indicates the gene expression levels showed significant difference between film mulch and the control at P<0.05 by using t-test (LSD). In the present study, film mulch decreased the soil water content creating a mild drought stress compared with the control.
