Hd6 required functional Hd1 to delay flowering under LD conditions. Flowering-time phenotypes of Hd6 lines in rice are shown. Days to flowering after sowing were measured for each plant. Hd6+, Hd6−, and Hd6ox indicate the genotypes of each line (+, functional allele; −, nonfunctional allele; ox, overexpresser driven by the 35S promoter). Each line was grown under the indicated photoperiod conditions. Each bar represents the mean ± sd of flowering time from 10 to 20 plants. Representative results of two to four independent experiments are shown. Hd1+/hd6−, Nipponbare (an hd6-defective cultivar); Hd1+/ Hd6+, NIL(Hd6) (NIL in a Nipponbare genetic background with a functional Hd6 allele from a Kasalath indica cultivar; Supplemental Fig. S2); Hd1+/Hd6ox1 and Hd1+/Hd6ox2, two independent transgenic rice plants (T3) overexpressing Hd6 cDNA in Nipponbare; hd1−/hd6−, NIL(Hd1) (NIL in a Nipponbare genetic background with a nonfunctional Hd1 allele from the Kasalath cultivar); hd1−/Hd6+, NIL(Hd1,6) [progeny line from NIL(Hd1) and NIL(Hd6)]; hd1−/Hd6ox3 and hd1−/Hd6ox4, two independent transgenic rice plants (T3) overexpressing Hd6 cDNA in NIL(Hd1).
