@article{7106, abstract = {PIN-FORMED (PIN) transporters mediate directional, intercellular movement of the phytohormone auxin in land plants. To elucidate the evolutionary origins of this developmentally crucial mechanism, we analysed the single PIN homologue of a simple green alga Klebsormidium flaccidum. KfPIN functions as a plasma membrane-localized auxin exporter in land plants and heterologous models. While its role in algae remains unclear, PIN-driven auxin export is probably an ancient and conserved trait within streptophytes.}, author = {Skokan, Roman and Medvecká, Eva and Viaene, Tom and Vosolsobě, Stanislav and Zwiewka, Marta and Müller, Karel and Skůpa, Petr and Karady, Michal and Zhang, Yuzhou and Janacek, Dorina P. and Hammes, Ulrich Z. and Ljung, Karin and Nodzyński, Tomasz and Petrášek, Jan and Friml, Jiří}, issn = {2055-0278}, journal = {Nature Plants}, number = {11}, pages = {1114--1119}, publisher = {Springer Nature}, title = {{PIN-driven auxin transport emerged early in streptophyte evolution}}, doi = {10.1038/s41477-019-0542-5}, volume = {5}, year = {2019}, }
