Spindle lengths in Arabidopsis WT and ask1-1 male meiosis

LengthLength Difference
μm
WTL1 7.0 ± 0.11-a (n = 45)
L2 9.7 ± 0.11-b (n= 26)L2 − L1 = 2.7
L38.3 ± 0.11-c (n = 16)L3 − L1 = 1.3
ask1-1 L1 7.0 ± 0.11-d (n = 12)
L2 8.4 ± 0.11-e (n= 23)L2 − L1 = 1.4
L39.8 ± 0.11-e (n = 25)L3 − L2 = 1.4
L411.8 ± 0.11-e (n = 11)L4 − L3 = 2.0
L54.91-f (n = 1)L6 − L5 = 0.7
L6 5.6 ± 0.11-f (n = 5)L1 − L6 = 1.4

Data are presented as means ± SEM, except for L5 ofask1-1. (n = no. of spindles measured). When similar spindle lengths were observed for meiosis I and II, the means were calculated with values from meiosis I and II.

    • F1-a  WT metaphase I and II.

    • F1-b  WT anaphase I.

    • F1-c  WT anaphase II.

    • F1-dask1-1 metaphase I and meiosis II.

    • F1-eask1-1 anaphase I and meiosis II.

    • F1-fask1-1 meiosis II.
