| 英文摘要 | Paracentric inversion is known to inhibit genetic recombination between normal and inverted chromosomal segments in heterozygous arrangements. insect inversion polymorphisms have been studied to reveal adaptive processes for maintaining genetic variation. we report the first paracentric inversion in rice (oryza sativa), which was discovered in our effort to clone the floral organ number gene fon3. recombination at the fon3 locus on the long arm of chromosome 11 was severely suppressed over a distance of more than 36 cm. an extensive screening among 8,242 f-2 progeny failed to detect any recombinants. cytological analysis revealed a loop-like structure on pachytene chromosomes, whereas fish analysis showed the migration of a bac clone from a distal location to a position closer to the centromere. interestingly, the locations where the genetic recombination suppression began were coincided with the positions of two physical gaps on the chromosome 11, suggesting a correlation between the physical gaps, the inversion breakpoints. transposons and retrotransposons, and tandemly arranged members of gene families were among the sequences immediately flanking the gaps. taken together, we propose that the genetic suppression at the fon3 locus was caused by a paracentric inversion. the possible genetic mechanism causing such a spontaneous inversion was proposed. |
