zeatin
C2/Highly SpecializedTechnical/Scientific
Definition
Meaning
A natural plant hormone (cytokinin) that promotes cell division and growth.
Specifically refers to adenine-type cytokinin first discovered in maize (Zea mays) kernels; used in plant tissue culture and biotechnology to stimulate shoot formation and delay senescence.
Linguistics
Semantic Notes
Term is almost exclusively used in botany, plant physiology, and agricultural science. It denotes a specific chemical compound (C10H13N5O).

Learning
Memory Aids
Mnemonic
Think: ZEA (from maize, Zea mays) + TIN (as in a small metal container for a precious compound). "The precious growth factor from maize kernels."
Conceptual Metaphor
ZEATIN IS A GREEN SIGNAL FOR CELLS TO DIVIDE.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "зеатин" (direct transliteration) – the correct Russian botanical term is "зеатин" but ensure it's recognized in the specific scientific context, not mistaken for a brand or common noun.
Common Mistakes
- Pronouncing it /zeɪˈætɪn/ (incorrect stress).
- Using it as a general term for fertilizer (it's a specific hormone).
- Misspelling as 'zeatine' (confusion with chemical suffix '-ine').

FAQ
Frequently Asked Questions
Not directly in field agriculture; its primary use is in laboratory-based plant tissue culture and micropropagation for research and producing clones of elite plants.
Yes, while originally discovered as a natural compound in maize, synthetic zeatin and its analogs (like kinetin) are widely used in laboratory settings.
They are stereoisomers. Trans-zeatin is the biologically active, naturally prevalent form, while cis-zeatin is less active and often synthetic.
It is a plant-specific hormone and is not known to have hormonal effects on animals or humans. Safety in a laboratory context relates to standard chemical handling procedures.
