iny hairs on Arabidopsis thaliana roots elongate via tip growth, in which new membrane is added specifically at the root hair tip. Vincent et al. (page 801) now show that a phosphatidylinositol transfer protein (PITP) related to yeast Sec14p is critical for this polarized growth, suggesting that PIP 2 may be the start of the polarity cascade in this system. The authors show that Arabidopsis has...

I need not have worried. As Sydney himself put it in the introduction to Loose Ends, a collection of his best columns from the first three years published in book form: “[Peter] accepted no excuses about being late for deadlines and I am pleased to say I managed to meet all of these, if only by microseconds in some cases”. Whether microseconds, hours or, occasionally, a couple of days before th...

rust caused by phakopsora pachyrhizi syd. is a major constraint to soybean product in asia. early detection and possibilities of controlling plant diseases by the integration of several image processing methods has been the subject of extensive research. the main contribution of this paper is to present different methodologies for quantitatively detecting soybean rust at each stage of disease d...

Active zones (AZs) are presynaptic membrane domains mediating synaptic vesicle fusion opposite postsynaptic densities (PSDs). At the Drosophila neuromuscular junction, the ELKS family member Bruchpilot (BRP) is essential for dense body formation and functional maturation of AZs. Using a proteomics approach, we identified Drosophila Syd-1 (DSyd-1) as a BRP binding partner. In vivo imaging shows ...
