Leaf margin organisation and the existence of vaterite-producing hydathodes in the alpine plant Saxifraga scardica (Elsevier, 2018-04-01)Some sections of species within the genus Saxifraga deposit a chalky crust on the surface of their leaves, originating from the guttation medium produced by the sunken hydathodes found generally at or near the leaf margin. ...
In bacteria, alternative sigma factors regulate diverse stress responses and developmental programs. Sigma factors share a common pool of core RNA polymerase (RNAP). Sharing has been assumed to occur through partitioning ...
The self-organization of plant microtubules inside the cell volume yields their cortical localization, stable alignment, and sensitivity to external cues. (Public Library of Science (PLoS), 2018-02-20)Many cell functions rely on the ability of microtubules to self-organize as complex networks. In plants, cortical microtubules are essential to determine cell shape as they guide the deposition of cellulose microfibrils, ...
