摘要：population. Two independent sets of co-localized loci were isolated as single Mendelian factors, and haplotypes that promote flowering and reduce germination derived from weedy and cultivated rice, respectively. The presence of negative and positive correlations indicates that the rice complex has maintained two contrasting patterns of SD-FT coadaptation, with the positive being "recessive" to the negative pattern. Modeling with isogenic lines suggests that a negative pattern could generate a greater synergy (difference between haplotype variants) than the positive one for seedbank persistence, or enhanced plant adaptation to seasonal changes in temperature or moisture. However, the early-flowering dormant genotype of a positive pattern could also have a selective advantage over its counterpart for weeds to avoid harvesting. The isolated haplotypes could be used to manipulate cultivars simultaneously for germination ability and growth duration.
