SOC1, oil palm, flowering, in situ RNA hybridizationAbstract
The oil palm industry has been affected by abnormality in its clonal palm. Oil palm abnormality which arose from in vitro regeneration was first detected during flowering process. In this study, localized expression of an oil palm homologue of SOC1 gene was investigated using in situ RNA hybridization. Tissue specific localization expression of OPSOC1and OPSOC1-3’ showed that SOC1 is expressed in both normal and abnormal flower. The gene is highly expressed in abnormal oil palm flower throughout flower initiation and development. The role of SOC1 in inducing floral organ and its expression pattern provides a better understanding of regulation of OPSOC1 in normal and abnormal oil palm flower.
