Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

A Tip-Localized Phospholipid Is Key for Polar Growth of Pollen Tubes

Zhou et al. demonstrate that phosphatidylserine regulates Rab GTPase-mediated vesicle trafficking and polar growth of pollen tubes. Plant Cell https://doi.org/10.1105/tpc.19.00844 Background: Pollen tube growth is an indispensable event during double fertilization in flowering plants. This peculiar…
