SD, standard deviation.
Significantly different than wild type, P-value ≤0.01, Fisher’s uncorrected LSD.
GC, germ cells, proliferative zone cell is considered REC-8 positive, HIM-3 negative nucleus.
sME, start of meiotic entry region, number of germ cell diameters from distal end to the first HIM-3 positive germ cell.
eME, end of meiotic entry region, number of germ cell diameters from distal end to the last REC-8 positive germ cell.
Strain maintained at 15°, shifted to 20° at mid-L4 stage.
Null(0) for mir-35 family; actual genotype mir-35 thru 41(nDf50) mir-42-45(nDf49).
