Major abiotic stress signaling phytohormone abscisic acid (ABA) in japonica rice (Oryza sativa L.) cv. Dongjin with or without endophytic Paecilomyces formosus LWL1 under no stress (NS) and prolonged heat stress (HS)
ABA was analyzed in freeze-dried samples of 30 randomly collected plants from each of three treatment replicates from three independently conducted experiments. Values of ABA analysis in respective treatments were pooled together to calculate the mean±SD. For each set of treatments, the asterisk on error bar indicates significant differences between plants treated with and without P. formosus at the P<0.05 level by Student’s t-test
