Hmm, that textbook rule—high auxin-to-cytokinin for roots, low for shoots—is what I learned too. But with our rare *Umbong*, I’ve watched a balanced ratio stubbornly push out a shoot, then a root from the same callus, like it’s remembering its own rhythm. My lab notes are full of these quiet rebellions. It reminds me of watching my daughter’s hands on the loom; the pattern is in the book, but the true form emerges under her fingers, with a life of its own.
