Glucosinolate Transporter1 involves in salt-induced jasmonate signaling and alleviates the repression of lateral root growth by salt in Arabidopsis.
Title: Glucosinolate Transporter1 involves in salt-induced jasmonate signaling and alleviates the repression of lateral root growth by salt in Arabidopsis.
Expression of glucosinolate (GLS) importers GTR1 and GTR2 inside the stele, along with earlier observations, suggest three possible routes of stele-synthesized aliphatic GLS after their synthesis: (i) GTR-dependent import to cells symplastically connected to cortical cells and rhizosphere; (ii) GTR-independent transport via xylem to the shoot; and (iii) GTR-dependent import to GLS-degrading myrosin cells at the cortex.
Title: Rhizosecretion of stele-synthesized glucosinolates and their catabolites requires GTR-mediated import in Arabidopsis.
dimerization of GTR1, possibly induced by dephosphorylation of the Thr residue located between the possible transmembrane regions, regulates its plasma membrane localization.
Title: Dimerization of GTR1 regulates their plasma membrane localization.
GTR1 would be involved in the translocation of JA and JA-Ile in plant and may be contributed to correct positioning of JA and JA-Ile to attenuate an excessive wound response in undamaged leaves
Title: GTR1 is a jasmonic acid and jasmonoyl-l-isoleucine transporter in Arabidopsis thaliana.
Phosphorylation of AtGTR1 is not directly involved in regulating AtGTR1 transport activity.
Title: Phosphorylation at serine 52 and 635 does not alter the transport properties of glucosinolate transporter AtGTR1.
GTR1 role of transport processes in leaf glucosinolate distribution
Title: Elucidating the role of transport processes in leaf glucosinolate distribution.
glucosinolate can specifically translocate from rosette and roots to inflorescence in a GTR1- and GTR2-dependent manner
Title: Upon bolting the GTR1 and GTR2 transporters mediate transport of glucosinolates to the inflorescence rather than roots.
GTR1 and GTR2 control the loading of glucosinolates from the apoplasm into the phloem. [GTR1]
Title: NRT/PTR transporters are essential for translocation of glucosinolate defence compounds to seeds.
