While the presence of melanin in plants is more complex and enigmatic than in animals, the answer is yes, plants do have melanin or melanin-like pigments.
Here's a more detailed breakdown:
-
What is Melanin? Melanin refers to a group of high molecular weight, black and brown pigments that are formed through the oxidation and polymerization of phenolic compounds.
-
Melanin in Different Kingdoms: Melanin is present across all kingdoms of living organisms.
-
The Enigma of Plant Melanin: While present, melanin in plants remains less understood than in other organisms. Its precise structure and function can vary significantly across different plant species.
-
Plant "Melanin" Examples: The reference notes that it is technically melanin or melanin-like pigments. This suggests that while plants may not produce melanin identical to that found in animals, they create similar compounds.
- These pigments are generally produced through the oxidation and polymerization of phenolic compounds.
-
Conclusion: The presence of melanin, or at least melanin-like pigments, is acknowledged in plants, even if its nature is not as clearly defined as it is in animals.
