The promotive effect of auxin on shoot cell expansion provided the bioassay used to isolate
this central plant hormone nearly a century ago. While the mechanisms underlying auxin …

transporters are involved in sensing cellular pH changes.•Root derived small mobile …

Plant cells are embedded within cell walls, which provide structural integrity, but also
spatially constrain cells, and must therefore be modified to allow cellular expansion. The …

Understanding plant-microbe interactions requires examination of root exudation under
nutrient stress using standardized and reproducible experimental systems. We grew …

Despite being composed of immobile cells, plants reorient along directional stimuli. The
hormone auxin is redistributed in stimulated organs leading to differential growth and …

The expansion of gene families during evolution could generate functional diversity among
their members to regulate plant growth and development. Melatonin, a phylogenetically …

The gaseous hormone ethylene plays a key role in plant growth and development, and it is a
major regulator of stress responses. It inhibits vegetative growth by restricting cell …

In the last three decades, more than 200 monoclonal antibodies have been raised against
most classes of plant cell wall polysaccharides by different laboratories worldwide. These …

The phytohormone auxin has been shown to be of pivotal importance in growth and
development of land plants. The underlying molecular players involved in auxin …

Plant roots navigate in the soil environment following the gravity vector. Cell divisions in the
meristem and rapid cell growth in the elongation zone propel the root tips through the soil …
