Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

textThe expression of SMALL AUXIN UP-RNA 39 (SAUR 39) is positively regulated by the TIG1 transcription factor. TiG1 promotes cell elongation and increases the tiller angle in rice (Zhang et al., 2019). The SAUR39 gene is expressed at higher levels in older leaves and low levels in inflorescence and roots. SAUR39 gene showed rapid induction by transient change in different environmental factors, including auxin, nitrogen, salinity, cytokinin, and anoxia. Plants over-expressing SAUR39 display reduced shoot and root growth, altered shoot morphology, reduced size of vascular tissue, low yield, and decreased basipetal auxin transport (Kant et al., 2009). Thus, it is a negative regulator of auxin synthesis and transport. The SAUR39 gene has an auxin-responsive element in its 5′ untranslated region.
