If the flag leaf was a primary source of Cd transported to the grain, it might be expected that greater transport would lead to lower Cd content in the flag leaf of the high-Cd NIL, or at a minimum the flag leaf Cd content of NILs would converge during grain filling.
The higher Cd contents of NIL qcd4-1,2 brice rice might be caused by the increases in whole plant accumulation before heading and translocation from total leaves after heading through the interaction between qcd4-1 and qcd4-2, much like in bread and durum wheat [ 34, 35].

The Cd contents of "Nipponbare", NIL qcd4-1, aNILNIL qcd4-2 leates at 35 days after heading were 54, 49, and 70% as much as at 5 days, respectively (P < 0.05), and NIL qcd4-1,2 contents had decreased by 40% (P < 0.001).
However, grain Cd content of the high-Cd NIL was significantly greater than that of the low-Cd NIL at all harvests (P < 0.001).
Although whole-plant Cd content of the low-Cd NIL was 6% greater (across all harvests) than the high-Cd NIL (P < 0.05), this was attributable to 15% greater biomass in the low-Cd NIL.
The original mapping of the QTL identified phenotypic variation in grain protein content between NILs of approximately 10% [[ 33]].
Total Cd contents in parts other than the ears (leaf blades, sheaths, and culms) of NIL qcd4-2 did not change from 5 to 35 days after heading, but "Nipponbare" and the other NILs decreased (P < 0.05).
But their actual narrative content is nil.
And which countries will suffer the ignominy of "nil points"?
