TL;DR: Unlike what is seen in planta, some additional transport of the benzoic acid is observed in yeast and mammalian cells expressing AtPGP1, suggesting that other factors present in plant tissues confer enhanced auxin specificity to PGP-mediated transport.

TL;DR: Water stress recognized by the root system predominantly results in shoot-localized ABA action that culminates in a focused response in guard cells, revealing a spread of physiologically active ABA from the vascular tissue into the areoles of the cotyledons.

TL;DR: A highly sensitive and accurate multiplex gas chromatography–tandem mass spectrometry (GC–MS/MS) technique is reported for indole-3-acetic acid, abscisic acid, jasmonic Acid, 12-oxo-phytodienoic acid and salicylic acid.

TL;DR: Results suggest that a regulatory loop appears to exist by which sulphate deficiency, through an increase in glucobrassicin turnover and nitrilase 3 accumulation, initiates the production of extra auxin leading to increased root growth and branching, thus allowing the root system to penetrate new areas of soil effectively to gain access to fresh supplies of sulphur.

TL;DR: Experiments on epidermal strips showed that in contrast to wild type, the sulfonylurea glibenclamide had no effect on stomatal opening in mrp5‐1 plants, which strongly suggests that AtMRP5 may also function as an ion channel regulator.
