Figure 1 displays how Pard6b knockdown suppresses formation of the blastocyte cavity, although it does not affect early blastomere cleavages in embryo (Table 1).

SasG therefore promotes cell adhesion.)PMID:17660408IDA: Inferred from Direct Assay

Figure 8 shows that SasG-expressing SH1000 cells form a biofilm measured with crystal violet staining and read at A570. SH1000 variants carrying pALC2073 expressing SasG with eight, six and five B repeats resulted in the formation of a biofilm. Strains expressing four, two or one B repeats did not form biofilms (Fig. 8c)

Figure 6 and figure 7 display unbalanced cell growth and division in the absence of StkP. Wild-type cells were able to develop one cell-division ring in the center while cells with mutated strains became over-elongated and formed multiple rings, leading to division into more than two daughter cells.

Figure 2A shows that the fusion of amino acids 218 to 309 of Tus to the C-terminus of GFP restored nuclear targeting, defining the NLS sequence of Tus. Further depicted in Figure 3A, alteration of any one of the basic amino acids 218-309 resulted in pronounced perturbation of nuclear targeting of the fusion proteins. )PMID:20126275IMP: Inferred from Mutant Phenotype

Culturing of yceP mutants and wild-type strain in LB did not lead to a variation in observed biofilm formation while twofold (P = 0.052) and threefold (P = 0.001) increases in biofilm occurred in LB glu upon deletion of yceP (Figure 1A). Lastly when biofilm formation was observed in a continuous flow system in M9C glu medium, the yceP deletion caused the cells to form a more random, scattered, and globular biofilm with far less surface coverage (Figure 2B).
