GmCHLI1

Gene Details:

GmCHLI1, a gene encoding the I subunit of magnesium (Mg)-chelatase, which functions in hexamers as responsible for the semi-dominant etiolation phenotype in soybean.
We performed map-based cloning and found that a CHLI homolog in soybean, GmCHLI1, is responsible for the etiolation phenotype.
These results indicate that the GmCHLI1 and GmCHLI2 missense mutations not only affect interaction capacity but also influence the transcript abundance of Mg-chelatase subunits and subsequently block chlorophyll biosynthesis.
These results indicate that all four GmCHLIs can function as the CHLI subunit but that their functions could be dominant negatively affected by non-synonymous mutation of either copy of GmCHLI1 and GmCHLI2, further suggesting that the different copies might interacted in nature.
