TL;DR: A general model for auxin signalling is suggested in which the modulation of the relative abundance of different Aux/IAA proteins can determine which down-stream responses are induced, and suggests that root hair initiation is controlled by the Relative abundance of SHY2 and AXR3 in a cell.

TL;DR: A biotin switch isobaric tagging for relative and absolute quantification (iTRAQ)-based method to identify S-acylated proteins from Arabidopsis is described and it is demonstrated that LRR-RLK FLS2 is required for a full response to elicitation by the flagellin derived peptide flg22, but is not required for localization to the plasma membrane.

TL;DR: It is shown that TIP1 binds the acyl group palmitate, that it can rescue the morphological, temperature sensitivity, and yeast casein kinase2 localization defects of the yeast S-acyl transferase mutant akr1Δ, and that inhibition of acylation in wild-type Arabidopsis roots reproduces the Tip1− mutant phenotype.

TL;DR: BSim, a highly flexible agent-based computational tool for analyzing the relationships between single-cell dynamics and population level features, is introduced, enabling the modeling of bacterial behavior in more realistic three-dimensional, complex environments.

TL;DR: It is concluded that ERULUS is a key auxin-controlled regulator of cell wall composition and pectin dynamics during root hair tip growth.
