Aneuploidization under segmental allotetraploidy in rice and its phenotypic manifestation.

ABSTRACT:

Key message

We report a repertoire of diverse aneuploids harbored by a newly synthesized segmental allotetraploid rice population with fully sequenced sub-genomes and demonstrate their retention features and phenotypic consequences. Aneuploidy, defined as unequal numbers of different chromosomes, is a large-effect genetic variant and may produce diverse cellular and organismal phenotypes. Polyploids are more permissive to chromosomal content imbalance than their diploid and haploid counterparts, and therefore, may enable more in-depth investigation of the phenotypic consequences of aneuploidy. Based on whole-genome resequencing, we identify that ca. 40% of the 312 selfed individual plants sampled from an early generation rice segmental allotetraploid population are constitutive ane
