Can plant fruit and seeds be albino like animals?
When thinking of albinism in fruits, the only thing I could think of is strawberries. Yes, there can be albinism in strawberries! They are nearly always assocoated with excess nitrogen and are usually tasteless. According to a research by Lieten et al, their mineral composition also differes. Albino strawberries contain higher N:Ca and K:Ca ratio than normal fruits. Another study by Sharma et al shows that albino strawberries show less lipoxygenase activity. Also, Hwang et al and team found that presence of more than normal silicon also causes, among many other things, albinism.



You can get more information here, here, here and here. Obviously, there could be numerous other examples, but albino strawberries is all I could remember.

PS the exact genetic cause and mechanism of albinism in strawberries is not known yet. When searching online, I only found a study by Plante et al which suggests presence of mixoploid cells over a critical number which might have an effect on it.
