Cold stress involves CBF dependent regulatory pathway to remodel wood formation in<i>Eucalyptus gunnii</i>hybrids Open
While being the most planted tree worldwide, most Eucalyptus species are sensitive to frost. Long-term exposure to cold temperatures, among other abiotic cues, triggers modification of secondary xylem differentiation in Eucalyptus , but th…

Functional investigation of five R2R3-MYB transcription factors associated with wood development in Eucalyptus using DAP-seq-ML Open
A multi-tiered transcriptional network regulates xylem differentiation and secondary cell wall (SCW) formation in plants, with evidence of both conserved and lineage-specific SCW network architecture. We aimed to elucidate the roles of sel…
