Potassium fertilisation reduced late embryogenesis abundant (LEA) gene expression in Malaysian rice (MR220) under water stress condition

The application of potassium fertiliser might mitigate water stress effects in developing rice, thus influencing Late Embryogenesis Abundant (LEA) gene expression and growth in the plant tissue. This study was conducted to examine LEA gene expression in its drought tolerance mechanisms and the growt...

This study was conducted to examine LEA gene expression in its drought tolerance mechanisms and the growth of Malaysian Rice (MR220) when exposed to water stress and potassium fertilisation. Three treatments were developed, namely the control (CF; Continuously flooding + 80 kg K2O/ha), water stress under standard potassium fertilisation (WS; Water Stress 25 days + 80 kg K2O/ha) and water stress under high potassium fertilisation (WSK; Water Stress 25 days + 120 kg K2O/ha).
