Does anyone happen to recall the title or author of a science fiction novel with the following major plot elements?
My recollection, not a quote:
On an alien planet, whose plants are not green (lacking chlorophyll), and thus are less efficient and being outcompeted by introduced Earth plants. Later, however, a scientist genetically engineers the native life to also produce chlorophyll, resulting in a more efficient photosynthesizer, which then outcompetes the Earth plants, causing the nascent colony to starve as they cannot eat the alien plants.
I believe this book is also loosely linked to other books by the same author, via the main character.
