要旨本文	Tropical timber species face increasing environmental stress due to climate change and deforestation. Understanding molecular mechanisms underlying resilience traits is essential for sustainable forestry. This study highlights gene expression profiling in Falcataria falcata (sengon) which is a fast-growing leguminous tree widely cultivated in Indonesia. Despite its adaptability, sengon is vulnerable to drought stress, which has become more frequent due to climate change. Morphological responses and drought-induced gene expression in sengon seedlings from different provenances and ages were analyzed by comparing the expression of genes regulating abiotic stress as different periods of water stress as compared to the control. Morphological parameters and expression profiles of drought-related genes were analyzed using quantitative real-time PCR (qPCR) and RNAseq. The insights contribute to molecular breeding and conservation of tropical timber resources under a changing climate.
