TI - PIN-FORMED and PIN-LIKES auxin transport facilitators KW - AUXIN KW - AUXIN TRANSPORT KW - PHYTOHORMONE N2 - The phytohormone auxin influences virtually all aspects of plant growth and development. Auxin transport across membranes is facilitated by, among other proteins, members of the PIN-FORMED (PIN)and the structurally similar PIN-LIKES (PILS)families, which together govern directional cell-to-cell transport and intracellular accumulation of auxin. Canonical PIN proteins, which exhibit a polar localization in the plasma membrane, determine many patterning and directional growth responses. Conversely, the less-studied non-canonical PINs and PILS proteins, which mostly localize to the endoplasmic reticulum, attenuate cellular auxin responses. Here, and in the accompanying poster, we provide a brief summary of current knowledge of the structure, evolution, function and regulation of these auxin transport facilitators UR - https://drive.google.com/file/d/1WDVuyx10fSOaWJQasNMjZX30wUH8rsKR/view?usp=drivesdk ER -
