On September 7, 2026, the rubber tree biology team at Hainan University successfully constructed a single-cell development map of the xylem in rubber trees for the first time. This study utilized single-cell transcriptomics sequencing and chromatin openness sequencing techniques to identify 10 cell clusters and clarify the composition and differentiation relationships of xylem cells. The research found that the fast-growing variety RK525 exhibits enhanced spindle lineage development and more active secondary cell wall deposition. The team identified key transcription factors HbSND2 and HbC3H14, confirming that changes in chromatin state are involved in regulating the growth rate of rubber trees. These findings were recently published in the international journal *Plant Cells and Environment*, providing important resources and theoretical support for the molecular improvement of fast-growing, high-yielding, and high-quality rubber tree wood.
