Over the years, I have recorded white-flowered forms of the following, and I understand that they tend to be double recessive variants. Is this in fact the case?
- Cirsium palustre
- Prunella vulgaris
- Geranium robertianum
- Centranthus ruber
- Hyacinthoides non-scripta
I really don't know how it is e.g. for the black Iris. Sometimes there is a yellow flowering between them. And someone told me that it like the dark glove missing. I like this explanation. As it sound to me not really having a genetical basis.
Hi
I've found this article its not the latesest but it might be interesting for you.
Hello Tamás,
thank you for that - yes - that isn't the latest, but it's still OK! Very nice!
best wishes,
Thomas
In many cases, it is a LOF (loss of function) mutation in the anthocyanin biosynthesis pathway that blocks the ability of plants of producing anthocyanins. This can happen at the whole plant level or at a modular level (e.g. Flowers). A lot of this has been studied in Ipomoea and other plant models. Search in Google Scholar and you'll find plenty of articles. Good luck.
It also happens in Fritillaria persica. And as Fernando wrote it is a mutation in the pathway of the coloring.
The yellow one is rare. But there are intermediary ones.
