Figure 7From: Callose plug deposition patterns vary in pollen tubes of Arabidopsis thalianaecotypes and tomato speciesVariation in first callose plug position in seven tomato species. (A) Average length of the first interval in two independent experiments (black and white bars). An unpaired t test was performed between two independent experiments. Error bars are SEM, P< 0.5. (B) Distribution of first interval lengths. 150μm was used as a criterion to group first interval lengths. The percentages represent the proportion of pollen tubes with the first interval <150μm. S.hab: S. habrochaites; S.pen: S. pennellii; S.sit: S. sitiens; S.per: S. peruvianum; S.chi: S. chilense; S.pim: S. pimpinellifolium; S.lyc: S. lycopersicum.Back to article page
