Method p.851 left column 2nd paragraph:"[Investigators] demonstrate that Arabidopsis PHBs [prohibitin] (AtPHBs) are mitochondrial factors that are predominantly expressed in proliferative tissues and provide genetic evidence that type-I plant PHBs are necessary to support cell division in apical tissues."
Comments p.855 right column bottom paragraph:"Table 2 presents the average root cortex cell growth parameters of atphb3KO and Col-0 plants 1 week after germination. The overall rate of root growth in wild-type plants was approximately 300 µm/h, whereas in atphb3[KO] roots it was less than 100 µm/h." p.857 left column top paragraph:"Besides the cell division rate, cell expansion was also influenced. Root meristem cells spend most of their growth in the division (meristematic) zone (135±10 h in Col-0 Table 2), and once they leave the actual meristem they expand very rapidly to their mature size in a matter of hours (5±1 h in Col-0)." Note-2nd column from left, "Col-0" is wildtype
