-- SPON Andrus 1951 Proc Amer Soc Hort Sci 57:345. Butler 1954 TGC 4:9. De Jong 2004 Theor Appl Genet = Myb domain transcription factor. Anthocyanin absent except on cotyledons and lower sides of leaves; anthocyanin accumulation more intense under growth retarding conditions; under low temperature and low light intensity, foliage becomes yellowish, webs of corolla-like tissue appear between segments of the calyx, and fertility may be reduced.
Anthocyanin modifications: intensification, reduction or elimination Yes
