Anthocyanin induction
nounPronunciation: /ˌænθoʊˈsaɪənɪn ɪnˈdʌkʃən/
The enhanced synthesis and accumulation of anthocyanin pigments in plant tissues in response to various abiotic stresses including UV radiation, cold, drought, and high light. Anthocyanins function as antioxidants and photoprotectants under stress conditions.
Plain English
Plants produce more red and purple pigments in response to stress, which help protect them from damage.
Etymology & History
Usage
"Anthocyanin induction in apple leaves exposed to UV-B radiation provided significant photoprotection against oxidative damage."
Style guide notes: Use 'anthocyanin induction' to emphasize the stress-triggered response; specify wavelength when discussing UV stress contexts.

Frequently Asked Questions
What stresses trigger anthocyanin induction in plants?
UV radiation, cold temperature, drought, high light intensity, and nutrient deficiency all stimulate anthocyanin synthesis.
How do anthocyanins protect stressed plants?
Anthocyanins scavenge free radicals, absorb excess light energy, and reduce photoinhibition in chloroplasts under stress.
Why Test Candidates on This?
Anthocyanin induction is regularly tested in plant stress physiology, pigment metabolism, and visible stress response assessments.
