Leaf excision evokes an ultradian gene expression rhythm to prime de novo root regeneration. Leaf excision evokes an ultradian gene expression rhythm to prime de novo root regeneration

Ultradian rhythm of gene expression in excised leaf. Overall design: After the synchronization treatment (dark and incubated under dark and 16 °C conditions for 24 h after excision), excised leaves were incubated at 22 °C in continuous light condition and were collected every 30 min with a total of 16 time points for transcriptome analysis through RNA-seq.
