Abstrakt
Drought is one of the most important issues in crop production which may disrupt
physiological processes and biochemical metabolism in rice plants, including the emergence of
plant resistance gene expression such as OsAB13 and OsLEA, the formation of ROS (Reactive
Oxygen Species), namely hydrogen peroxide (H2O2), as well as the emergence of gene expression
related to antioxidant enzyme activity such as OsAPX1, OsCATA, Mn-SOD, Cu/Zn-SOD, and
APX Cytosolic. Besides the emergence of plant resistance gene expression, ROS, and changes in
gene expression related to antioxidant enzymes, rice plants also produce salicylic acid which acts
as an endogenous signal to activate plant resistance gene responses and can encourage plant
resistance responses such as antioxidant enzyme activity. The treatments in this study included:
control, 15% PEG 6000, 15% PEG 6000 + SA 1 mM, and SA 1 mM. The results showed that the
interaction between treatments and rice plant varieties significantly affected plant height, root
length, total chlorophyll, and H2O2 content. The expression of the OsAPX1, OsCATA, Mn-SOD,
and Cu/Zn-SOD genes increased in the 15% PEG 6000 treatment compared to the control. In the
15% PEG 6000 + SA 1 mM treatment, there was an increase in gene expression of APX
Cytosolic, Cu/Zn-SOD, and OsCATA compared to the 15% PEG 6000 treatment. The OsLEA is
expressed in Siakraya and Sertani 1 as an indicator of resistance to drought stress, and the
OsAB13 is expressed in Indragiri, Sertani 1, and Siakraya varieties as an indicator of resistance
to drought stress.
