Chromosomal fragment deletions in different pollen developmental stages. a The number of aneuploid sperm and pollen for B73 and the B73-inducer line. b The degree of chromosome fragmentation (in CAU5) was estimated in meiotic and mitotic stage by single cell and nucleus sequencing and observation under microscope. ^∗ χ ² test, P represents the difference of aneuploid frequency of B73-inducer sperms (14/52) and B73 sperms (3/50). ^#χ² test, P represents the significant difference of aneuploid frequency of B73-inducer pollens (9/26) and B73 pollens (3/25). ^$ χ ² test, P represents the difference of aneuploid frequency of CAU5 pollens (6/22) and CAU5 microspores (1/72)
