A type of aneuploidy,trisomy,in which cells have an abnormal number of chromosomes (2n =2x+1),results in significant morbidity and mortality.The mechanisms by which the abnormal number (1.5 times) of normal genes located on the chromosome leads to cellular dysfunction and the specific features of various trisomic syndromes are not well understood.Primary trisomy (2n =2x+1) results in significant physiological and morphological abnormalities.In rice (Oryza sativa; 2n =2x =24),different primary trisomic individuals carrying a different chromosome as the extra chromosome show different chromosome-specific abnormalities.
