文摘
- •
Hormone metabolite profile done during development of maize reproductive organs.
- •
Novel trans-zeatin metabolite 6-(3-methylpyrrol-1-yl)purine identified.
- •
6-(3-methylpyrrol-1-yl)purine has anticytokinin properties and inhibits CKX enzymes.
- •
Distinct preferences of maize CK-glucosyltransferases lead to cis-zeatin accumulation.
