DNA fragmentation in psl mutant. The DNA ladder of psl plants was detected by DNA gel blot analysis. Equal amounts of total DNA isolated from psl and wild-type plants at the same developmental stage were loaded in each lane. Positions of DNA standards (identified in bases) are indicated at right. 10 DBF: 10 days before flowering; 2, 7 DAF: 2 and 7 days after flowering
